India Renewable Curtailment Exposes Grid Bottleneck Behind Clean Power Growth

Ember

India renewable curtailment reached around 300GWh in January-March because of transmission constraints, showing that the country’s clean power buildout is now running ahead of grid readiness. The lost generation accounted for nearly two-thirds of India’s total renewable curtailment in the first quarter.

India renewable curtailment was concentrated in renewable-heavy northern and western grid pooling stations, especially Rajasthan and Gujarat. These regions have added large solar and wind capacity, but transmission expansion has not kept pace.

India renewable curtailment is strategically important because wasted clean power weakens project economics, increases peak power costs and delays the energy transition. It also highlights rising demand for grid materials, including copper, aluminium conductors, transformers, electrical steel and battery storage systems.

The curtailed volume represented around 1.5-2% of total renewable generation from interstate transmission system-connected plants in northern and western India. On 30 March alone, India lost 34GWh of renewable output because of insufficient transmission margins.

Transmission Delays Threaten Renewable Project Economics

India has achieved only around 80% of its annual transmission buildout targets over the past five years. That gap is now becoming visible in curtailment, grid connection delays and weaker returns for renewable developers.

One in four interstate transmission schemes scheduled for the 2026-27 fiscal year faces delays of at least one year. Around 20GW of renewable capacity is expected to face grid connectivity delays exceeding four months.

These delays carry direct financial consequences. A six to twelve-month delay in solar projects can reduce internal rates of return by 100-200 basis points because of lost early cash flows and higher financing costs.

The problem also affects India’s fuel import exposure. Curtailed renewable generation could have displaced costly gas-fired power during peak demand periods, reducing reliance on expensive LNG at a time when spot gas prices were elevated by the US-Iran war.

For metals markets, the message is clear. India’s renewable buildout now needs faster transmission investment, which means more demand for aluminium conductor, copper cable, transformers, substations, steel structures and grid equipment.

BESS Deployment Offers Near-Term Relief

Battery energy storage systems could provide a near-term solution at renewable pooling stations. Ember estimates that around 3-4GW of two-hour storage could absorb most curtailed renewable generation.

The economics are becoming more attractive. Stored solar power delivered at 7-8 rupees/kWh would remain below the Rs9-10/kWh many Indian states pay for peak-demand electricity.

This makes BESS deployment more than a technical fix. It is a cost-control tool, a grid-stability tool and a way to protect renewable project returns.

Battery storage demand also has materials implications. BESS deployment supports demand for lithium, phosphate, graphite, copper, aluminium, power electronics and thermal management systems, with lithium iron phosphate likely to remain important for stationary storage.

India’s southern region recorded no transmission-related renewable losses because renewable additions and transmission readiness were better aligned. That contrast shows that curtailment is not inevitable; it is a planning and execution problem.

India’s clean power transition will therefore depend on synchronising generation, transmission and storage investment. Solar and wind additions alone will not deliver energy security if power cannot move from renewable zones to demand centres.

The Metalnomist Commentary

India’s renewable curtailment shows that the energy transition is becoming a grid materials story. The next bottleneck is not only solar panels or wind turbines, but transmission capacity, storage deployment and the metals needed to move clean electricity.

China Renewable Energy Plan Supports Metals Demand but Leaves Growth Uncertain

China, Renewable Energy Plan

China renewable energy plan for 2026-30 points to continued structural demand growth for copper, aluminium, lithium, vanadium and rare earths. However, the metals impact will depend on how far wind, solar, storage and grid investment move beyond targets that China is already close to reaching.

China renewable energy plan targets wind and solar at more than 50% of total installed power capacity by 2030 and positions them as the main source of power generation. The wording is important because wind and solar already account for around 48% of China’s installed power capacity.

China renewable energy plan therefore provides policy support but not necessarily a new demand shock. The key issue for metals producers is whether Beijing pushes deployment materially above the 50% threshold and introduces additional incentives for solar, storage and grid infrastructure.

China’s total installed power capacity reached 4,010GW by the end of May. Solar accounted for 1,260GW and wind for 660GW, with both sectors still growing at double-digit rates.

Copper and Aluminium Depend on How Far Renewables Expand

Renewable infrastructure remains a major source of metals consumption. Solar projects require aluminium for frames, mounting systems and electrical applications, while wind turbines consume aluminium, copper, speciality steels and rare earth permanent magnets.

Industry estimates put aluminium consumption at around 13,500t for every 1GW of solar capacity and up to 3,000t for 1GW of wind capacity. Further expansion could therefore create substantial incremental demand.

However, China is already close to the plan’s minimum capacity target. Wind and solar together represent about 48% of total installed capacity, leaving only a modest increase required to exceed 50%.

This has made market participants cautious. If deployment slows after the target is reached, incremental aluminium demand could be weaker than previous renewable investment cycles.

The outcome changes if actual capacity moves toward 55% or higher. Chinese policy targets are often designed with room for overachievement, meaning the final installed share could materially exceed the stated minimum.

Copper has a stronger structural demand case because renewable generation also requires transmission, substations, grid reinforcement and electrical equipment.

Copper demand from China’s wind and solar sectors is expected to reach around 1.85mn t this year, almost three times the 620,000t consumed in 2020. That growth demonstrates how renewable buildout is already reshaping Chinese copper consumption.

Storage and Charging Add Another Critical Metals Demand Layer

The plan extends beyond renewable generation. China is targeting 300GW of new energy storage capacity and 40mn electric vehicle charging units by 2030.

Storage deployment strengthens demand for lithium and other battery materials. Rapid renewable penetration increases the need to balance variable generation, making grid-scale batteries increasingly important to the power system.

Lithium consumption from energy storage could rise substantially over the next decade. However, strong demand growth does not automatically mean higher lithium prices because new mine and processing capacity may expand just as quickly.

Vanadium could also benefit if long-duration flow batteries capture part of China’s storage market. Rare earth demand may gain additional support from wind turbine generators and high-performance electric motors.

Charging infrastructure adds another copper and aluminium demand channel. Millions of additional charging points require cables, connectors, distribution equipment and grid upgrades.

The plan therefore supports a wider metals ecosystem than wind and solar installations alone. Generation, storage, charging and grid reinforcement all add material intensity to China’s energy transition.

The biggest uncertainty is execution. China has already built renewables at enormous scale, so future metals demand will depend on whether policy accelerates deployment beyond current momentum rather than merely formalising existing trends.

The Metalnomist Commentary

China’s new energy plan is supportive for metals, but the 50% wind-and-solar target alone is not the real story because the country is already close to it. The stronger demand signal will come from how aggressively Beijing expands storage, grids and renewable capacity beyond the minimum target.

BHP renewable power for copper projects accelerates South Australia’s low-carbon shift

BHP

BHP renewable power for copper projects is moving from strategy to execution in South Australia. The new deals with Neoen link Olympic Dam, Carrapateena and Prominent Hill to dedicated wind and battery assets, reshaping their long-term emissions profile. As a result, BHP renewable power for copper projects is becoming central to the group’s decarbonisation roadmap and its compliance with Australia’s safeguard mechanism.

Wind, storage and safeguard compliance for Olympic Dam

BHP will source 100MW of renewable electricity from Neoen’s 300MW Goyder North wind farm and 200MW Goyder battery. This follows an earlier contract for 70MW from Goyder South, which has supplied Olympic Dam since July. Together, these agreements should cover about 70pc of BHP’s copper-related electricity demand in South Australia by 2030.

Olympic Dam falls under Australia’s safeguard mechanism, where on-site generation counts towards covered scope 1 emissions. In 2023-24, Olympic Dam produced 244,321t of CO₂e, staying just below its 246,875t baseline. Therefore, BHP renewable power for copper projects is not just an ESG narrative but a direct tool for avoiding the surrender of additional ACCUs or safeguard credits.

Meanwhile, BHP still surrendered 47,000 ACCUs across 16 other facilities, including iron ore, coal and nickel operations. This highlights how decarbonisation progress remains uneven across the portfolio. However, the South Australian power strategy shows how dedicated renewable contracts can reduce both compliance risk and long-term power-price exposure.

Copper decarbonisation, diesel displacement and long-term risk

BHP is targeting a 30pc cut in operational greenhouse gas emissions by 2029-30 versus 2019-20 levels. The group has already reduced operational emissions to 8.7mn t CO₂e, a 36pc decline from that baseline. In this context, BHP renewable power for copper projects provides a tangible bridge between climate commitments and actual asset-level performance.

The company ultimately aims for net-zero operational emissions by 2050, mainly by displacing diesel in its mining fleets. Progress here has lagged because of technical delays in low-emission vehicle deployment. However, locking in large-scale renewable power for copper operations buys valuable time while mobile-equipment solutions mature.

For customers and policymakers, BHP renewable power for copper projects offers a clearer line of sight to lower-carbon copper supply. This matters as OEMs, grid operators and EV supply chains increasingly differentiate between standard and low-emission copper units. It also strengthens South Australia’s positioning as a hub for renewable-powered mining and processing.

The Metalnomist Commentary

BHP’s structured shift into contracted wind and storage underscores how decarbonisation is becoming a core competitiveness issue for copper miners. For metals buyers, the next phase will involve translating these renewable power deals into quantifiable, auditable carbon advantages at the cathode, rod and cable level.

Soaring Renewables Growth Still Falls Short of COP28 Target, Varies Widely by Region

Renewable energy deployment is speeding up at an “unprecedented rate” but still falls short of what it will take to hit the tripling of global capacity that countries committed to at last year’s United Nations climate summit, the International Renewable Energy Agency warns in an assessment published earlier this month.

That’s in spite of renewable energy producers installing 473 gigawatts of new capacity last year, accounting for 85% of the new electricity entering the global system, Canary Media reports.

Renewable energy capacity grew 14% last year, contributing to a 10% compound annual growth rate between 2017 and 2023, IRENA says. But it’ll take annual growth of 16.4% to meet countries’ 2030 deadline to triple the amount of renewable energy available around the world by 2030.

“Renewable energy has been increasingly outperforming fossil fuels, but it is not the time to be complacent,” said IRENA Director-General Francesco La Camera. “Renewables must grow at higher speed and scale” unless countries want to “face failure in reaching the tripling renewables target,” thereby putting the climate goals in the 2015 Paris agreement at risk.

The commitment to triple global renewable energy capacity and double the rate of annual energy efficiency improvements by 2030 was one of the signature results of last year’s COP28 climate summit in Dubai. “But IRENA’s analysis found that even if renewables continue to be deployed at the current rate over the next seven years, the world will fall 13.5% short of the target to triple renewables to 11.2 terawatts,” Climate Home News reports.

“Today’s report is a wake-up call for the entire world: while we are making progress, we are off track to meet the global goal,” said COP28 President and fossil fuel CEO Sultan Al Jaber. “We need to increase the pace and scale of development.”

Decarbonization Divide

La Camera added that the top-line numbers obscure “ongoing patterns of concentration in geography” that “threaten to exacerbate the decarbonization divide and pose a significant barrier to achieving the tripling target.” The numbers show Asia leading the world in renewable power generation followed by North America, and South America recording an “impressive jump”, but Africa lagging at just 3.5% annual growth due to a persistent and dire lack of climate finance.

Global Renewables Alliance CEO Bruce Douglas echoed the concern about the imbalances in deployment between regions. “We shouldn’t be celebrating,” he said. “This growth is nowhere near enough and it’s not in the right places."

Even with the aggregate growth data for Asia, Climate Home says, analysis by the REN21 international policy group shows the continent as a whole—excluding renewables powerhouse China—accounting for less than 18% of new capacity additions in 2023.

“The justice piece is huge and too often overlooked,” Douglas said, with IRENA reporting that Africa has seen less than 2% of global renewables investment over the last two decades. “That’s not acceptable in terms of an equitable transition,” he declared.

In the Financial Times, human geographer Brett Christophers of the University of Uppsala’s Institute for Housing and Urban Research cautions against mistaking China’s big numbers on renewable energy deployment for a global trend.

“The view that the world is finally winning in the energy transition away from fossil fuels is increasingly prominent,” he writes. But “comforting as this take may be, we need to throw cold water over it. We are emphatically not yet winning, and it is time to stop pretending that we are.”

‘Hugely Misleading’

It’s “hugely misleading” to look at the global growth rate for renewables when “there is not one single energy transition but a series of regional transitions of widely varying form, pace and scope,” Christophers adds. That matters because “we need rapid growth in renewable investment everywhere,” in every region of the world.

But at present, “the outsized materiality of one—China’s—means global figures veil more than they reveal. They currently look impressive because, and only because, China’s do.”

Elsewhere, the New York Times reports that the U.S. oil industry is still booming, with high prices and recent growth in demand translating into higher profits, even as renewable energy and electric vehicles surge. “That the price and demand for oil have been so strong suggests that the shift to renewable energy and electric vehicles will take longer and be more bumpy than some climate activists and world leaders once hoped,” the Times writes.

While the industry has gained from high prices brought on by the COVID-19 recovery and Russia’s war in Ukraine, the Times lists other factors that have improved oil companies’ prospects: under pressure from Wall Street to offer better financial returns: they’ve become more hesitant to go into debt to pay for new growth, while laying off workers and automating more of their operations. The result is that oil and gas operators in the lower 48 U.S. states have generated US$485 billion in free cash flow since 2021, compared to $140 billion in the previous decade.

“The environmental consequences of the oil industry’s financial turnaround are mixed,” the Times writes, citing Brookings Institution Director Samantha Gross. “Producing and burning fossil fuels releases greenhouse gases that are warming the planet. But higher oil prices are also making cleaner forms of energy more attractive.”

Adani Green BESS Expansion Makes Khavda a Major Grid Storage Platform

Adani Green Energy

Adani Green BESS capacity has reached 3.37GWh at the Khavda renewable energy park in Gujarat, marking a major step in India’s effort to make large-scale renewable power more reliable and dispatchable. Adani Green Energy added 2GWh to the 1.37GWh installed in March.

Adani Green BESS development at Khavda is significant because the project is now the largest single-location battery storage installation outside China, according to the company. The system is co-located with AGEL’s 30GW renewable energy project, of which 9.9GW is already operational.

Adani Green BESS expansion also signals how India’s clean energy transition is moving beyond generation capacity alone. Solar and wind projects need storage to manage intermittency, stabilise grids and supply power during peak demand periods.

The company plans to scale its storage footprint quickly. It is targeting more than 10GWh of new capacity by March 2027 and aims to reach 50GWh over the next five years.

Khavda Storage Strengthens Renewable Power Dispatchability

The Khavda BESS uses lithium-ion battery technology integrated with advanced energy management systems. This allows faster grid response, better stability and more reliable renewable power delivery.

This matters because India is adding renewable power at scale, but grid flexibility remains a major constraint. Battery storage helps convert variable solar and wind generation into usable power during high-demand periods.

AGEL said the 3.37GWh system can power about 1mn homes for a full day. It can also meet peak electricity demand in cities such as Indore or Chandigarh, or supply the entire state of Goa.

The Khavda project therefore shows how battery storage is becoming core electricity infrastructure. It is no longer only a backup tool or pilot technology.

For India, this type of storage capacity supports energy security, renewable integration and reduced dependence on fossil fuel peaking power. It also strengthens the case for more domestic battery materials, cell manufacturing and power electronics capacity.

Battery Storage Growth Lifts Materials and Supply-Chain Demand

Large BESS projects create demand across several material chains. Lithium-ion batteries require lithium, graphite, copper, aluminium, separators, electrolytes, battery management systems and thermal control technologies.

Copper demand is also supported by cabling, grid connections, transformers and power conversion systems. Aluminium can benefit through enclosures, busbars, structural systems and cooling components.

India’s rapid storage targets could therefore deepen demand for battery raw materials and downstream manufacturing. The country will need reliable supply chains for cells, modules, inverters and grid equipment if it wants to scale from gigawatt-hours to tens of gigawatt-hours.

The Khavda system also highlights the strategic link between renewable energy and industrial policy. Battery storage deployment can create demand signals for local manufacturing, recycling and critical minerals processing.

However, scaling to 50GWh will require capital, land, grid integration, battery procurement and long-term project economics. Storage must become not only technically viable, but also financially repeatable.

Adani Green’s commissioning shows that India is moving quickly. The next challenge is building a domestic ecosystem that can support storage deployment without relying too heavily on imported battery materials and equipment.

The Metalnomist Commentary

Khavda shows that the renewable energy race is becoming a storage race. India’s next clean-energy bottleneck will not be only solar or wind capacity, but the battery materials, grid equipment and financing needed to make renewable power dispatchable.

Rio Tinto Kennecott wind VPPA secures 78.5MW for Utah copper decarbonization

Kennecott

The Rio Tinto Kennecott wind VPPA expands renewable sourcing for copper production. Rio Tinto signed a 15-year renewable energy supply agreement with TerraGen for its Kennecott copper mine. The Rio Tinto Kennecott wind VPPA covers 78.5MW of renewable power. Therefore, Kennecott copper mine decarbonization moves closer to execution.

TerraGen will deliver supply from the Monte Cristo I wind farm. The project totals 238.5MW in Hidalgo County and began commercial operations this week. Meanwhile, miners are shifting to long-term renewable contracts to manage carbon exposure. As a result, VPPAs are becoming a mainstream tool for metals producers.

TerraGen wind output supports a 15-year renewable energy supply agreement

The VPPA ties Kennecott’s load to wind generation attributes. Rio Tinto will source 78.5MW from the Monte Cristo I asset. However, a VPPA settles financially and does not physically deliver electrons to Utah. Therefore, the contract still supports emissions accounting through renewable attributes.

This structure can hedge power pricing and reduce reported emissions intensity. It can also align with customer demands for low-carbon copper. Meanwhile, copper buyers are tightening Scope 3 expectations across supply chains. As a result, renewable contracts can improve offtake competitiveness.

Kennecott adds solar capacity alongside wind procurement

Kennecott is building a broader clean energy portfolio. Rio Tinto installed a 5MW solar plant in 2023. It is also finishing a 25MW solar plant. Therefore, the Rio Tinto Kennecott wind VPPA complements on-site generation.

Kennecott operates integrated downstream infrastructure beyond the mine. The site includes a concentrator, smelter, refinery, and logistics assets. Meanwhile, these assets drive large, steady electricity demand. As a result, renewable contracting can support decarbonization across the full copper value chain.

The Metalnomist Commentary

Integrated copper sites win when they decarbonize smelting and refining, not only mining. Meanwhile, VPPAs offer speed, but they do not fix local grid constraints. Therefore, Rio Tinto should pair contracts with operational efficiency and on-site flexibility.

Australia Invests $63 Million in Neoen’s Renewable Energy Projects

Neoen

The Australian government has committed A$100 million ($63.2 million) in funding to French renewable energy producer, Neoen, to support the development of three large-scale renewable energy and battery storage projects in Australia. This investment reflects Australia's ongoing push to expand its renewable energy infrastructure and reduce reliance on fossil fuels.

Focus on Battery Storage and Solar Power

The three projects in question include:

1. A 341MW Battery Energy Storage System (BESS) in Western Australia.
2. A 270MW BESS in Queensland.
3. A 440MW peak solar farm in New South Wales.

These projects, which are still under development, aim to enhance Australia's energy security by integrating large-scale storage solutions with renewable energy generation. The Western Australia BESS is particularly significant as it will be an extension of the already operational Collie Battery Energy Storage System, which stores and discharges 219MW of power. Once both parts of the Collie system are fully operational, they will support up to 20% of the state's average energy needs.

Neoen’s New South Wales solar farm, known as the Culcairn Solar Farm, is scheduled to begin generating 800 GWh/year by 2026, covering an area of 1,000 hectares. While a BESS at the site is a possibility, Neoen has yet to make any official announcements regarding that development.

Role of the Clean Energy Finance Corporation (CEFC)

The Clean Energy Finance Corporation (CEFC), a state-owned green investment fund, is providing the funding to Neoen. The CEFC has already been involved in funding a total of 2.3GW worth of battery storage projects across Australia, playing a crucial role in the country's transition to a cleaner, more sustainable energy grid.

Australia’s Renewable Energy Growth

Renewable energy generation has surged across Australia, now accounting for 25% of the country’s total power generation in 2023, up from 17% in 2017. During the same period, the combined share of gas and coal in power generation fell from 81% to 63%. This shift aligns with the government’s broader climate goals, including decarbonizing the energy sector and ensuring energy resilience.

The funding commitment to Neoen comes just a day after the Australian government allocated A$14.1 million to GrainCorp and Ampol to promote the development of sustainable aviation fuels and renewable diesel.

Tomago Aluminium Smelter Gains NSW Support as Power Costs Threaten Capacity

Tomago aluminium

Tomago aluminium smelter will receive additional support from the New South Wales government as Australia seeks to prevent the 600,000 t/yr facility from closing when its current electricity contract expires in 2028.

Tomago aluminium smelter support forms part of NSW's 2026-27 budget, alongside federal negotiations over a new long-term power purchase agreement. The governments are trying to create an electricity cost structure that keeps one of Australia's largest industrial power users commercially viable.

Tomago aluminium smelter owner Rio Tinto had previously warned that the operation could close because of unsustainable electricity costs. Losing the facility would remove substantial domestic primary aluminium capacity and weaken Australia's downstream manufacturing supply chain.

The proposed support illustrates a broader challenge facing energy-intensive industries: governments want to preserve strategic domestic production while electricity systems undergo a costly transition toward renewable generation and new grid infrastructure.

Power Agreement Becomes Critical to Tomago’s Future

Australia's federal and NSW governments agreed in December 2025 to pursue a long-term support package for Tomago.

The proposal includes a fixed-price power purchase agreement designed to provide greater certainty over one of the smelter's largest operating costs.

In return, Tomago would commit to investing A$1bn in the facility over ten years from 2028.

That investment could help modernise the smelter and improve its competitiveness while Australia's electricity market changes around it.

Primary aluminium smelting requires enormous volumes of continuous electricity. This makes smelters particularly vulnerable to high wholesale power prices, network costs and uncertainty around future supply.

Tomago's 600,000 t/yr capacity also gives the negotiations strategic importance beyond the individual company. Closure would materially reduce Australian primary aluminium production and increase reliance on imported metal for domestic industrial users.

The government is therefore effectively weighing the cost of supporting power-intensive manufacturing against the economic and strategic consequences of losing the capacity altogether.

Renewable Infrastructure Could Reshape Australia’s Aluminium Economics

NSW is also allocating A$291mn for road upgrades supporting transport of equipment into renewable energy zones.

This infrastructure investment is relevant to Tomago because the long-term competitiveness of Australian aluminium increasingly depends on access to large volumes of affordable renewable electricity.

Aluminium smelters can potentially become major anchor customers for renewable generation because they consume power continuously at industrial scale.

However, the transition requires sufficient generation, transmission and firming capacity to maintain stable electricity supply around the clock.

The state budget also reflects the continuing importance of fossil fuel revenues during that transition. NSW has raised its royalty forecasts following higher thermal coal prices triggered by the global gas supply shock.

Coal royalty revenue is expected to remain substantial over the coming years even as NSW invests heavily in renewable infrastructure.

This creates a transitional industrial model in which existing resource revenues help finance the power system required for future low-carbon manufacturing.

For aluminium, the outcome at Tomago could become a test case. If governments and industry can establish a competitive long-term electricity framework, Australia could preserve primary metal capacity while gradually reducing its carbon intensity.

The Metalnomist Commentary

Tomago demonstrates that the future of primary aluminium will increasingly be decided by electricity economics rather than ore availability. Australia has abundant resources and renewable potential, but retaining smelting capacity requires turning that energy advantage into reliable industrial power prices.

Alcoa Massena aluminum smelter investment anchors long-term US primary capacity

Alcoa Massena aluminum smelter

Alcoa Massena aluminum smelter investment marks a renewed commitment to US primary aluminum production and regional industrial jobs. The company has secured a 10-year, 240MW renewable power contract from the New York Power Authority, with extension options. This long-dated Massena renewable power deal underpins operations and gives Alcoa confidence to reinvest capital in the site. As a result, the plant’s future looks more secure in a market focused on low-carbon metal.

Alcoa will pair the new power deal with a $60mn modernization of the smelter’s anode baking furnace. The project, partially supported by a $6mn grant from Empire State Development, will run through 2028. Modern anode technology should improve energy efficiency and process stability, supporting lower emissions per tonne of primary aluminum. Therefore, the Alcoa Massena aluminum smelter investment aligns commercial resilience with decarbonisation goals.

Renewable power underpins Massena smelter competitiveness

The Massena renewable power deal is central to Alcoa’s cost and carbon strategy at the smelter. The 240MW allocation of renewable energy, starting 1 April, lowers exposure to volatile market power prices. It also strengthens Alcoa’s ability to market lower-carbon primary aluminum to automotive and packaging customers. Over time, options for two additional five-year terms could extend that visibility well beyond 2035.

Access to dedicated hydropower and other low-carbon sources is increasingly a competitive advantage in smelting. Many global smelters face pressure from higher fossil-based electricity prices and tightening climate policies. By contrast, Massena’s power structure gives Alcoa a stable platform for long-term contracts with downstream buyers. Consequently, the Massena renewable power deal reinforces the strategic value of US smelting capacity.

Modern anode baking furnace supports capacity and ESG goals

Upgrading the anode baking furnace is a critical part of the Alcoa Massena aluminum smelter investment. Carbon anodes are consumed in the electrolytic process, combining with oxygen from alumina and leaving molten aluminum. Furnace design and performance directly affect energy use, cell stability and overall emissions. New equipment should lift reliability, extend anode life and improve current efficiency in the pots.

It remains unclear whether nameplate capacity of 130,000 t/yr will change after the project. However, better anode performance often translates into higher effective output and lower unit costs. That, in turn, can support longer-term employment and justify further incremental improvements at the site. In a market where buyers increasingly demand traceable low-carbon aluminum, the Alcoa Massena aluminum smelter investment positions the plant as a more attractive supplier.

The Metalnomist Commentary

This package of renewable power and furnace modernisation shows how policy support can unlock private capital for hard-to-abate industries. If Massena’s upgraded profile leads to greener, more competitive primary aluminum, it could become a blueprint for other legacy smelters in North America. For downstream OEMs, a more secure and cleaner US supply base reduces dependence on higher-carbon imports.

Rio Tinto signs new wind deal for Kennecott to lock in 78.5MW renewable power via VPPA

Rio Tinto, Australia

Rio Tinto signs new wind deal for Kennecott to expand renewable power coverage for its Utah copper operations. Rio Tinto signed a 15-year renewable energy supply agreement with Terra-Gen for the Kennecott copper mine near Salt Lake City. Rio Tinto signs new wind deal for Kennecott to secure 78.5MW of renewable energy from TerraGen’s Monte Cristo I wind farm in Texas. Therefore, the miner is tightening the link between low-carbon electricity and copper supply reliability.

TerraGen will supply power from the 238.5MW Monte Cristo I wind farm in Hidalgo County, Texas. The wind facility began commercial operations this week. Meanwhile, Rio Tinto structured the purchase through a virtual power purchase agreement. As a result, the company can decarbonize its electricity footprint without requiring direct physical delivery.

VPPA structure extends the Kennecott decarbonization roadmap

Rio Tinto signs new wind deal for Kennecott as part of a broader decarbonization push at the site. The company installed a 5MW solar plant in 2023 and is close to finishing a 25MW solar plant. Meanwhile, the VPPA adds longer-term renewable coverage and price visibility. Therefore, Kennecott’s energy strategy is moving from pilot assets to portfolio-style procurement.

This approach is increasingly common for energy-intensive metals. VPPAs can hedge power exposure and reduce reported emissions intensity. However, they require careful accounting and contract management. As a result, the structure matters as much as the headline megawatts.

Integrated mining, smelting, and refining makes energy a strategic lever

Kennecott is an integrated copper complex, not only a mine. The site includes a concentrator, smelter, and refinery, plus transport and storage infrastructure. Meanwhile, electricity and heat costs influence operating margins across the chain. Therefore, renewable procurement can support both decarbonization targets and resilience during power market volatility.

Copper buyers are also tightening sustainability requirements. Lower-carbon power can help miners defend market access and premium contracts. However, the benefits depend on consistent operations and transparent emissions reporting. As a result, Rio Tinto signs new wind deal for Kennecott with both cost and customer strategy in mind.

The Metalnomist Commentary

Copper is becoming an electricity story as much as a mining story. Meanwhile, integrated smelting sites face greater scrutiny on Scope 2 emissions. Therefore, long-dated VPPAs will keep spreading across the copper industry as customers demand verified low-carbon supply.

Asia leads renewable capacity growth in 2024, but gaps widen

IRENA

Capacity milestones and technology mix

Asia leads renewable capacity growth in 2024 and shapes global additions. Asia leads renewable capacity growth with 71% of 582GW installed. Total renewable capacity rose 15% to 4.4TW. Solar added 453GW, while wind added 114GW. Renewables now hold 46.2% of global capacity, near fossil’s 47.3%.

Tripling target, regional gaps, and investment

Asia leads renewable capacity growth, yet the world lags the 2030 tripling goal. At today’s pace, capacity reaches only 10.3TW by 2030. Growth must accelerate to 16.6% yearly. Africa, Eurasia, Central America, and the Caribbean added just 2.8%. Closing gaps needs policy, finance, and technology transfer. Global energy investment will hit $3.3tn in 2025, with two-thirds “clean.” China remains the largest clean-energy investor.

Strong Asian momentum lifts solar, wind, and grid component demand. However, uneven access to capital limits broader adoption. Therefore, stable frameworks and concessional funding remain critical. Developers must also expand storage and transmission to absorb growth.

The Metalnomist Commentary

Asia’s surge is real, but global equity still lags. Expect supply-chain tightness in inverters, transformers, and HV equipment. Watch policy pipelines and grid upgrades to sustain installation velocity.

Mercedes bets on green aluminium from Norway's Hydro for next-gen CLA

Mercedes aluminium body

Mercedes is turning to green aluminium from Norway's Hydro to cut embedded emissions in its new CLA model. The green aluminium from Norway's Hydro is certified at just 3kg of CO₂ per kilogram of metal across mining, refining, smelting and casting. This compares with a global average of 16.7kg, giving Mercedes a meaningful reduction in material-related emissions. The alloy also contains 25pc post-consumer scrap, which further lowers its lifecycle footprint and supports circular-economy targets.

However, the company’s claim that CLA production is “net carbon-neutral” still depends on offsets. Mercedes powers the plant with 100pc renewable electricity, mainly externally sourced hydropower, which materially cuts scope 2 emissions. But scope 1 emissions from on-site processes and logistics, as well as upstream emissions from suppliers, remain. Therefore, the move to green aluminium from Norway's Hydro is a genuine step forward, even if the overall net-zero claim rests partly on controversial offset mechanisms that investors often scrutinise.

Green aluminium supports low-carbon steel and battery initiatives

The CLA’s use of green aluminium from Norway's Hydro forms part of a broader materials decarbonisation strategy. Mercedes says its latest battery cell design cuts emissions by about 30pc per cell through renewable energy in anode and cathode production. The company also relies on “net carbon-neutral” cell manufacturing at suppliers, since it does not produce cells in-house. As a result, the true impact depends on supplier practices and verification of their renewable power usage.

Meanwhile, Mercedes is layering in low-carbon steel to tackle emissions in chassis and body-in-white applications. The CLA incorporates steel from US producer Nucor’s Econiq-RE range, made using 100pc renewable energy. Mercedes also has a deal with Steel Dynamics for more than 50,000 t/yr of CO₂-reduced steel for its Tuscaloosa plant. Together with green aluminium from Norway's Hydro, these supply contracts show how OEMs are weaponising procurement to reduce embodied carbon ahead of incoming carbon border measures.

Demand for certified green aluminium rises faster than headline prices

Demand for certified low-carbon aluminium is rising as automakers prepare for tighter climate regulations and potential carbon border charges. Carmakers want to cut embedded emissions at the material level, especially for high-intensity metals such as aluminium and steel. This is likely to support growing premiums for Hydro’s Reduxa-style green aluminium grades and similar products from competitors. As a result, upstream smelters with renewable power and high scrap usage gain a strategic pricing advantage.

However, headline aluminium prices on global exchanges remain relatively stable despite bullish long-term forecasts. London Metal Exchange cash aluminium has traded in a narrow range over the past year, even as demand for differentiated “green” material accelerates. This suggests that the value is migrating into contract premiums and long-term offtake deals instead of the base price. Over time, producers unable to demonstrate low-carbon credentials may find themselves pushed into a discounted “grey” segment of the market.

The Metalnomist Commentary

Mercedes’ partnership around green aluminium from Norway's Hydro shows how decarbonisation is increasingly driven by procurement, not just tailpipe regulation. For metals producers, the message is clear: access to cheap renewable power and high-quality scrap streams will shape competitiveness more than pure tonnage growth. As carbon accounting tightens, the premium for verifiable low-carbon tonnes is likely to widen, rewarding early movers across the aluminium value chain.

Michigan BESS Projects Approved to Support Grid Reliability and Data Center Growth

Michigan BESS Projects

Michigan BESS projects received regulatory approval on 27 March, adding 1,332MW of battery energy storage capacity to support grid reliability, renewable power integration and large-load electricity demand. The Michigan Public Service Commission approved six battery energy storage system projects across two major demand areas.

Three of the Michigan BESS projects will provide a combined 1,000MW to support DTE Electric’s integrated resource plan. That plan calls for adding 15,000MW of solar and wind generation in Michigan, making storage capacity essential for balancing intermittent renewable output.

The remaining three projects, totalling 332MW, will support a 1,383MW data center being developed by Green Chile Ventures, an Oracle subsidiary. The storage assets are intended to improve reliability and reduce costs for customers as data center electricity demand rises.

Battery Storage Becomes Critical for Renewable Grid Planning

Battery energy storage systems are becoming a core part of Michigan’s clean power buildout. DTE Electric’s 1,000MW of approved storage will be tied to 20-year tolling agreements, giving the utility more flexibility as solar and wind capacity expands.

This matters because renewable power growth requires fast-response assets that can shift electricity from periods of high generation to periods of high demand. BESS projects can also reduce strain on the grid during peak periods and support more reliable power delivery.

Michigan BESS projects therefore represent more than a backup power investment. They are part of the infrastructure needed to make renewable generation useful at scale and to protect grid stability as electricity demand grows.

Data Center Demand Adds a New Storage Growth Channel

The data center-linked BESS projects show how artificial intelligence and cloud infrastructure are reshaping power markets. Green Chile Ventures must develop 1,383MW of energy storage to match the contracted demand of its data center project.

The approved 332MW is only the first phase of that requirement. Green Chile Ventures will bear the costs over 15 years, while DTE Electric will develop, own and operate the facilities.

This structure highlights a wider market trend. Data centers need faster power access, and battery storage can help bridge the gap between project timelines, grid constraints and customer affordability concerns. Michigan already hosts 74 data centers, with Detroit accounting for 32, making power infrastructure an increasingly important competitiveness factor.

The Metalnomist Commentary

Michigan BESS projects show that battery storage is becoming essential infrastructure for both renewable energy and AI-driven data center growth. The next bottleneck will not only be battery supply, but also transformers, grid equipment, copper, aluminium and permitting capacity.

Cop 31 Electrification Target Could Reshape Global Power and Metals Demand

Cop 31

Cop 31 electrification target proposed by Turkey would lift electricity’s share of global final energy consumption to 35% by 2035, from around 20% today. The IEA is urging countries to support the goal at the November climate summit in Antalya.

Cop 31 electrification target would place power systems at the centre of the next phase of global decarbonisation. Reaching the target would require substantial investment in generation, grids, storage and end-use electrification across transport, buildings and industry.

Cop 31 electrification target also carries major implications for metals demand. More electricity infrastructure would support long-term consumption of copper, aluminium, electrical steel, battery materials and other inputs used in transmission, storage and renewable generation.

The political challenge is financing. Developing countries warned that higher borrowing costs, limited technology access and weak capital availability could prevent them from participating in the transition at the same pace as wealthier economies.

Grid Investment and Finance Will Determine Delivery

Turkey proposed the 35% electrification goal during climate talks in Bonn. The IEA said the target is achievable and could become a major legacy of Cop 31 if governments reach agreement.

However, expanding electricity use requires far more than adding renewable generation. Countries need transmission lines, distribution networks, transformers, substations, storage systems and digital grid infrastructure.

That creates a significant industrial demand signal. Copper will be central to cables, transformers and electrical equipment, while aluminium will remain critical for transmission conductors and lightweight electrical applications.

Battery storage will also become more important as renewable penetration rises. This supports demand for lithium, graphite, copper and other battery materials, while alternative storage technologies could create additional demand for vanadium, zinc and other metals.

Developing economies face the biggest financing challenge. High borrowing costs can make power projects significantly more expensive even when renewable resources are strong.

Turkey and Australia therefore want finance to sit alongside electrification in the Cop 31 agenda. Ministers from Ethiopia, Colombia and other developing countries also stressed that implementation will depend on better access to capital and technology.

Without that support, electrification could widen industrial inequality. Countries with cheaper financing would build grids and clean power faster, while higher-risk markets could remain dependent on older infrastructure and more expensive energy.

Clean Power Source Will Decide Climate Impact

Electrification alone does not guarantee lower emissions. The climate benefit depends on how the additional electricity is generated.

Civil society groups and governments have warned that rising electricity consumption can still be supplied by coal, gas or other fossil fuels. That means the electrification target must be linked with clean generation expansion and fossil fuel transition policies.

The Powering Past Coal Alliance has called for governments to integrate electrification, clean power build-out and coal transition scenarios. It warned that rapid power demand growth could otherwise lock countries into new coal capacity.

Colombia also argued that faster renewable deployment is not enough without addressing the phase-out of fossil fuels. This debate will remain central to negotiations around the broader transition away from fossil energy.

For industrial supply chains, the distinction matters. A clean electrification pathway creates sustained demand for renewable generation, grids, batteries and low-carbon materials. A fossil-heavy pathway may still increase metals demand, but with a much weaker emissions benefit.

The 35% target therefore represents more than an energy consumption metric. It would influence capital allocation, power infrastructure planning and material demand across multiple sectors for the next decade.

The Metalnomist Commentary

A global electrification target would be a major structural driver for copper, aluminium, electrical steel and storage materials. But without affordable finance and clean generation, electrification could expand electricity demand faster than it reduces emissions.

Japex storage battery station supports Hokkaido renewable energy growth

Japex

Japex storage battery station development in Hokkaido marks a strategic shift in Japan’s upstream energy companies toward grid flexibility. The new Japex storage battery station in Tomakomai will support a stable supply of renewable energy as variable output rises. As a result, the project strengthens Japan’s broader push to integrate large-scale renewables without sacrificing reliability.

Japex will build the Tomakomai storage battery station as one of Japan’s largest power-storage facilities, with 20MW capacity. The company targets commercial operations in autumn 2027, aligning the Japex storage battery station with accelerating wind and solar additions in Hokkaido. Meanwhile, the firm highlights that storage batteries will play a growing role in balancing renewable energy output and maintaining grid stability.

Hokkaido emerges as a storage and renewables cluster

Hokkaido offers Japex strong fundamentals for expanding its battery storage business. The region already hosts significant renewable energy capacity and has made visible progress in adopting storage solutions. Therefore, locating the Japex storage battery station in Tomakomai leverages both existing infrastructure and future solar and wind growth.

Japex has already commissioned a smaller 2MW storage battery station in Chiba prefecture, gaining early operational experience. In Tomakomai, the company also runs two solar power plants and plans another for 2028, further deepening its presence in low-carbon assets. However, Japex emphasizes that the Tomakomai storage battery station will operate as a grid-level resource rather than being tied to a single power plant. This design allows the asset to respond dynamically to system needs across the local network.

The Metalnomist Commentary

Japex’s move into large-scale storage signals how traditional upstream players are repositioning for a decarbonised power system. By building a major storage hub in Hokkaido, the company is not just following renewable growth but actively enabling it. For metals and battery supply chains, sustained roll-out of 20MW-class projects across Japan will reinforce long-term demand for advanced battery materials and grid technologies.

Rio Tinto Boyne Smelters Secures A$2bn Australian Support for Renewable Aluminium

Rio Tinto

Rio Tinto Boyne Smelters will receive major government support as Australia moves to keep aluminium production viable during its energy transition. Canberra and Queensland will each provide A$1 billion over 10 years to support the 500,000 t/yr aluminium smelter at Gladstone.

The funding will be linked to production credits for aluminium made with renewable energy. In return, Rio Tinto will underwrite nearly A$7.5 billion in new energy generation and transmission in central Queensland.

Rio Tinto Boyne Smelters is strategically important because aluminium smelting is highly power-intensive. The agreement shows how Australia is using public funding to prevent industrial closures while shifting heavy industry away from coal-fired electricity.

Renewable Power Becomes Central to Aluminium Smelter Survival

The support package reflects the growing pressure on Australian metals processors. Rising energy costs and the phase-down of coal-fired generation have made long-term power security a critical issue for smelters, refiners, and steelmakers.

The plan to shift Rio Tinto Boyne Smelters toward renewable power was first flagged in 2024. Rio Tinto also indicated last year that the 1.68GW Gladstone coal-fired power plant could close on 31 March 2029.

BSL produced 370,000 tonnes of aluminium in 2025, below its 500,000 t/yr nameplate capacity. It remains Australia’s second-largest aluminium smelter after the 600,000 t/yr Tomago facility in New South Wales, which is also expected to receive major taxpayer support to remain open beyond 2028.

Australia Uses Industrial Policy to Protect Metals Capacity

Australian aluminium smelter support is becoming part of a wider industrial policy response. Federal and state governments have already pledged major funding for Whyalla steelworks, Glencore’s Mount Isa copper smelter, and Nyrstar’s smelters in Hobart and Port Pirie.

The Boyne agreement also connects aluminium production with carbon regulation. The facility is registered under Canberra’s safeguard mechanism and reported covered scope 1 emissions of 921,558t CO2e for the July 2023-June 2024 compliance year, below its baseline of 931,303t CO2e.

Rio Tinto owns 73.5% of Boyne, while YKK Aluminium, UACJ Australia, and Southern Cross Aluminium hold the remaining stakes. The ownership structure reinforces the smelter’s importance to both domestic and regional aluminium supply chains.

The Metalnomist Commentary

Australia is effectively deciding that aluminium smelting is too strategic to lose during the energy transition. The real test will be whether renewable power support can preserve industrial capacity without creating a permanent subsidy model.

SECI to Invest ₹25 Billion in 200MW Solar and Battery Storage Projects in Madhya Pradesh

India SECI

India’s Solar Energy Corporation Expands Green Push With New Projects in Dhar and 1,000MWh Storage Facility

SECI Accelerates Renewable Energy Drive with Major Investment in Madhya Pradesh

India’s Solar Energy Corporation of India (SECI) has committed ₹25 billion ($286.5 million) to develop key renewable energy infrastructure in Madhya Pradesh. SECI signed an initial agreement with the state government to build a 200MW solar project in Dhar and a 1,000MWh battery energy storage system.

The investment falls under the Central Public Sector Undertaking (CPSU) scheme and will be executed in phases. SECI, which operates under India’s Ministry of New and Renewable Energy, aims to strengthen the country’s clean energy capacity and reduce dependence on fossil fuels.

Long-Term Clean Energy Commitment Supports India’s Energy Transition Goals

The 200MW solar plant is part of a broader 500MW agreement signed in 2023 with MP Power Management Company Limited (MPPMCL). Under this agreement, SECI will supply renewable electricity to Madhya Pradesh for 25 years, reinforcing long-term power stability through sustainable means.

By investing in solar power and energy storage, SECI continues to lead India's green energy movement. The dual focus on generation and storage aligns with national goals to improve grid reliability and boost clean energy adoption across sectors.

Battery Storage to Play Crucial Role in Energy Security

The planned 1,000MWh battery storage project marks a significant step toward ensuring round-the-clock renewable power availability. With India's energy demands rising, storage infrastructure is essential to integrate intermittent sources like solar into the national grid effectively.

SECI’s announcement confirms its commitment to supporting India’s decarbonization strategy while strengthening Madhya Pradesh’s role as a clean energy hub.

Hillside Aluminium Smelter Future Hinges on South32 Eskom Power Deal

Hillside Aluminium

Hillside aluminium smelter operations beyond 2031 will depend on a new long-term power agreement between South32 and South African utility Eskom. The companies are negotiating a replacement contract for the KwaZulu-Natal smelter before its current discounted electricity supply arrangement expires.

The Hillside aluminium smelter is one of South Africa’s most important energy-intensive industrial assets. Securing competitively priced power is essential because aluminium smelting depends on stable, large-scale and affordable electricity.

South32 and Eskom have created a working group to explore ways to bring competitively priced renewable energy into South Africa’s national grid. The goal is to support Hillside’s future power needs while also benefiting Eskom’s wider customer base.

The talks come shortly after South32 moved its Mozal aluminium smelter in Mozambique into care and maintenance after failing to secure a new electricity supply agreement. That decision highlights the strategic risk facing smelters when power contracts expire without a commercially viable replacement.

Power Security Becomes the Main Aluminium Constraint

Electricity is the defining cost factor for primary aluminium. Smelters need continuous power, and even modest changes in tariffs can determine whether production remains competitive.

The Hillside aluminium smelter currently benefits from a discounted power contract that runs until 2031. A new agreement would secure the plant’s operating future beyond that date and reduce uncertainty for workers, suppliers and downstream customers.

South32’s experience at Mozal shows what is at stake. The Mozambican smelter was moved into care and maintenance after its electricity contract expired at the end of March and no new agreement was reached.

That outcome gives urgency to the Hillside negotiations. Without a competitive long-term power solution, South32 could face difficult decisions about one of its key southern African aluminium assets.

For Eskom, the talks also carry wider industrial policy significance. South Africa needs to preserve energy-intensive manufacturing while managing grid constraints, decarbonisation pressure and the transition toward cleaner power.

Renewable Power Could Support Low-Carbon Aluminium

The working group’s focus on renewable energy shows how aluminium supply is becoming tied to decarbonisation. Buyers increasingly want lower-carbon aluminium, especially in automotive, packaging, construction and industrial applications.

A renewable-linked power solution could improve Hillside’s long-term competitiveness. It would help South32 reduce emissions exposure while keeping the smelter connected to South Africa’s industrial base.

However, the challenge is execution. Renewable power must be competitively priced, reliable and integrated into the national grid in a way that supports continuous smelter operations.

The agreement could also set a precedent for other energy-intensive industries in South Africa. If Eskom and South32 can structure a viable low-carbon power model, it may help attract or retain industrial investment in metals, chemicals and manufacturing.

For the aluminium market, the message is clear. Future smelting capacity will depend less on ore or alumina access alone and more on long-term power security, grid reliability and carbon intensity.

The Metalnomist Commentary

The Hillside power talks show that aluminium competitiveness is now an energy strategy question. South32 and Eskom must prove that South Africa can keep heavy industry alive while moving toward lower-carbon electricity.

Brazil Critical Minerals Industry Needs Government Support to Move Downstream

Brazil, Critical Minerals

Brazil critical minerals industry development will depend on stronger government support, infrastructure and long-term capital if the country wants to move beyond raw material extraction. Industry executives at the Energy Summit in Rio de Janeiro argued that mineral wealth alone will not create competitive processing and manufacturing supply chains.

Brazil critical minerals industry has substantial geological potential, but projects face gaps in logistics, technology, processing capacity and financing. Predictable legal and regulatory frameworks will therefore be essential to attract investment with mine-development timelines measured in decades.

Brazil has recently strengthened its national critical minerals framework, with policy focused on domestic processing, transformation and higher-value production rather than exports of raw materials alone.

The industrial opportunity extends beyond individual minerals. Companies can improve project economics by recovering multiple metals and valuable by-products from existing mining and processing streams.

Renewable Power Could Give Brazil a Processing Advantage

Brazil does not need to replicate China’s critical minerals model to become competitive. Its advantage could come from combining mineral resources with abundant renewable electricity and water resources to build a lower-carbon processing base.

This matters because refining and mineral processing are often energy-intensive. Access to competitive renewable power can reduce operating costs and lower the embedded carbon of finished materials.

That advantage could become increasingly valuable as automotive, battery, aerospace and industrial customers demand more traceable and lower-carbon feedstock.

Brazil also needs to capture more value between the mine and final customer. Beneficiation, refining, recycling and advanced materials production create significantly more industrial value than exporting ore or concentrate alone.

Government support can help close the financing gap during this transition. Critical mineral projects typically require large upfront capital commitments and long development periods before generating cash.

The challenge is therefore not simply identifying deposits. Brazil needs infrastructure, technology transfer, skilled labour and stable rules that encourage companies to build processing capacity domestically.

Copper Investment Shows Scale of Industrial Opportunity

Copper illustrates both Brazil’s opportunity and the broader global supply challenge. Electrification, grids, renewable energy, energy storage and artificial intelligence infrastructure are increasing the strategic importance of the metal.

Major new discoveries remain difficult, while existing mines are often facing declining grades and higher development costs. This strengthens the value of large established mineral districts that can support expansions and new processing capacity.

Vale Base Metals is positioning Carajas as one of its main copper growth platforms. The company has outlined multi-billion-dollar copper investment in the region, including $3.5bn of planned spending between 2026 and 2030 alone.

Vale is also pursuing more automated mining technologies and hybrid extraction systems, including electric equipment. These investments could reduce operating emissions while improving productivity.

Copper recovery remains challenging because ore contains relatively small amounts of payable metal compared with total material moved. That makes efficiency, energy costs and by-product recovery increasingly important to project economics.

Brazil’s wider critical minerals strategy will face the same test. Resource scale provides the opportunity, but competitiveness will depend on whether the country can convert geology into processed materials and reliable industrial supply.

The Metalnomist Commentary

Brazil has the resources and renewable power to become more than a mineral exporter, but geology alone will not build a critical materials industry. The decisive step is using policy and capital to pull processing, technology and downstream manufacturing into the country.

Codelco Secures 1.5TWh of Renewable Energy to Power Copper Operations

Codelco

Chilean copper giant advances toward 100% clean energy target

Chilean copper producer Codelco signed two major renewable power purchase agreements (PPAs) totaling 1.5TWh annually, supporting its goal of achieving a 100% clean energy matrix by 2030. The deals highlight Codelco’s commitment to sustainable copper production through long-term renewable energy sourcing.

New PPAs cover full operations and future demand

The first PPA grants 1TWh/year to Generadora Metropolitana, a joint venture between France’s EDF and Chile’s AME. The second assigns 0.5TWh/year to GR Power Chile, backed by Spain’s Grenergy. These agreements will begin in January 2026 and run through December 2040. They will supply power across Codelco’s mining divisions and cover future expansions.

Grenergy confirmed the energy will come from hybrid projects, including the 340MW Monte Aguilar photovoltaic plant and battery energy storage systems (BESS) in the Biobio region. The agreement guarantees 24/7 electricity availability.

Codelco deepens clean energy strategy

This follows Codelco’s previous 2024 PPAs totaling 1.8TWh/year signed with Colbun, Atlas Renewable Energy, and Innergex. Together, these efforts support Chile’s broader decarbonization goals while ensuring energy security for one of the world’s most critical copper producers.

The Metalnomist Commentary

Codelco’s strategic shift to clean energy solidifies Chile’s role in low-carbon copper supply. These PPAs also reflect the global mining sector’s accelerating push toward sustainability amid growing ESG expectations.
