Alcoa Corporation announced an additional power purchase agreement to support the future restart of the San Ciprián aluminum smelter in Spain. This latest agreement is with Endesa, a leading company in the Spanish electricity sector that is a subsidiary of the Enel Group. The agreement will provide power balancing services for the smelter load from 2024 to at least 2030.

Balancing services provide electricity to the smelter's consumption point, either from baseload volumes from a power purchase agreement with Endesa, via other third-party agreements, or from the market directly. The agreement with Endesa would include up to 131 megawatts beginning in the second half of 2025 and through 2033, representing slightly more than 30 percent of the smelter's energy requirements at maximum capacity. The final volume and start of the baseload power deliveries can be adapted as the process to develop windfarms evolves.

The pricing terms are confidential. The agreement with Endesa will supplement the terms of a separate agreement reached earlier this year with Greenalia for up to 183 megawatts. That agreement, which is subject to windfarm permitting process, would represent approximately 45% of the energy required to meet the smelter's maximum capacity.

Together, the agreements with Endesa and Greenalia could provide up to approximately 75% of the smelter base load power. Alcoa is continuing to pursue options for the remaining 25% of the smelter's electricity requirements.
