Alcoa’s (NYSE:AA) San Ciprián complex has been impacted by the widespread power outage across Spain.
As a result of the outage, both the refinery and smelter at the complex were affected.
The company is conducting a thorough assessment of the facility to determine the full extent of the operational and financial impact.
Spain and Portugal have been hit by a major power outage, which has been causing chaos along the Iberian Peninsula with gridlocked traffic, trains unable to operate, hospitals relying on backup power, and nuclear power stations automatically shut down.
It’s been reported that Spanish grid operator REE said the outage was caused by a sudden and large drop in power supply, leading the grid interconnection between Spain and France to trip.
Meanwhile, during Q1 2025 Alcoa’s net income increased 171% sequentially to US$548 million, with adjusted net income increasing 106% sequentially to US$568 million.
Adjusted EBITDA excluding special items increased to US$855 million, a 26% increase sequentially. The company finished the first quarter with cash of US$1.2 billion.
For Q2 2025, the aluminium segment “expects sequential unfavourable impacts of US$90 million due to US Section 232 tariffs on imports of aluminium from Canada, and $15 million of restart costs for the San Ciprián smelter. Alumina costs in the aluminium segment are expected to be favourable by $165 million sequentially”.
Alcoa is a global company focused on bauxite, alumina, and aluminum products with a vision to reinvent the aluminium industry for a sustainable future.
