Alcoa Corporation has announced the signing of a contract for renewable energy to support the planned restart in 2024 of aluminum smelting at the San Ciprián smelter in Spain. The long-term power purchase agreement is with Greenalia, an independent renewable energy developer and producer. Subject to windfarm permitting processes, the agreement would commence in 2024 and extend to the end of 2033.Due to exorbitant energy prices, Alcoa announced in December of 2021 a two-year curtailment of aluminum smelting at the site. During the curtailment, Alcoa is working to secure power purchase agreements and make improvements to prepare the smelter for the planned restart to begin in January of 2024.The agreement is expected to provide up to 183 megawatts of the smelter’s baseload power consumption, representing approximately 45 percent of the energy required to meet the smelter’s maximum capacity of 228,000 metric tons per year. The contract’s pricing terms are confidential. Alcoa is continuing to pursue options for the remaining 55 percent of the smelter’s electricity requirements.While the smelter is curtailed, the casthouse and the San Ciprián alumina refinery continue to operate.
