San Ciprián reanuda el rearranque tras el apagón eléctrico

La empresa conjunta recibe certezas sobre la resiliencia de la red eléctrica

MADRID, 14 de julio de 2025 – Hoy, Alcoa Corporation (NYSE: AA, ASX: AAI) y su socio en la empresa conjunta, IGNIS Equity Holdings, SL (IGNIS EQT), han anunciado que se reanudará el proceso de rearranque de la planta de aluminio de San Ciprián, en España.

El 28 de abril, el complejo San Ciprián de Alcoa se vio afectado por un apagón generalizado en toda España. Como consecuencia de esta interrupción del suministro, tanto la refinería como la planta de aluminio de San Ciprián resultaron afectadas, lo que repercutió significativamente en la capacidad para llevar a cabo un rearranque completo y a tiempo de la planta de aluminio. Tras evaluar los daños ocasionados, la empresa conjunta decidió pausar el rearranque hasta que el Gobierno de España proporcionara detalles suficientes sobre las causas del apagón y las medidas previstas para evitar que se repita.

“Hemos revisado el informe del Gobierno de España sobre las circunstancias que causaron el apagón, así como las medidas e inversiones previstas para mejorar la resiliencia de la red eléctrica. También nos hemos reunido con representantes del gobierno nacional y autonómico, y hemos recibido certezas de que seguirán promoviendo acciones para ofrecer una energía fiable y competitiva”, afirmó Rob Bear, vicepresidente de operaciones de Alcoa en España. “En base a estos factores y a las declaraciones públicas recientes del Gobierno, la empresa conjunta ha decidido reanudar el rearranque de la planta de aluminio.”

La empresa conjunta estima que el proceso de reinicio estará finalizado a mediados de 2026.

Según los precios actuales, la compañía está revisando sus estimaciones previas y prevé registrar una pérdida neta (antes de impuestos e intereses de minoritarios) para la planta de aluminio de aproximadamente entre 90 y 110 millones de dólares, lo que equivale a entre 0,35 y 0,42 dólares por acción común en 2025. Se espera además que el consumo de efectivo para las operaciones de la planta se aproxime a entre 110 y 130 millones de dólares en 2025. Este cambio desfavorable frente a las estimaciones previas se debe al retraso en la finalización del rearranque y al ingreso correspondiente que ahora se proyecta que pase de 2025 a 2026.
