Other renewable electricity developments We rely on renewable and non-renewable electricity to power our mines, processing plants and supporting infrastructure. We are working to displace gas and coal-fired power with solar PV, wind and other renewable technologies. We are focusing on the transition to renewable energy sources in 5 main regions: the Pilbara in Western Australia, RBM in South Africa, bauxite operations in Weipa, Australia, Kennecott in the US, and Oyu Tolgoi in Mongolia. Total electricity-related emissions from these assets were 0.9Mt CO 2 e in 2024. In 2024, RBM signed two renewable energy agreements: a 20-year 140MW wind PPA at Khangela and a 20-year 230MW wind PPA at Overberg. We also purchased EACs to cover the period until these assets are commissioned. At Kennecott, a 78.5MW wind VPPA and a 25MW solar PV facility were approved. Additionally, commissioning of a 5MW solar PV plant was completed in 2024, after undergoing rectification works and commissioning throughout the year. Construction on a second 25MW plant started in late 2024. At Amrun, a 12MW solar farm is under construction, and at Gove, 10MW of solar is being built. Decarbonising the electricity at each of these locations has varying degrees of complexity, including whether the power is externally or internally generated, land access requirements (including permitting and Traditional Owner engagement) and availability of commercial solutions. A 100MW solar PV facility can require a land area of approximately 200 hectares, equivalent to the operating footprint of one of our mines in the Pilbara. Although renewables benefit from established construction methods, are lower technical risk and relatively low impact on the ground, the sheer scale of the renewables footprint means that we must take the time required to find suitable sites and engage with Traditional Owners. We invest our own capital in renewable energy projects while also using other renewable energy procurement methods (such as PPAs and EACs) that align with global standards and practices. Under the GHG Protocol, renewable electricity must either have an EAC or be derived from renewable generation that is not contractually committed to another party. In alignment with the GHG Protocol we report eligible energy supplies as renewable and include them in our Scope 2 emissions reporting. Group electricity
