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.
