The battery power plant is the largest in the world according to the company, Vistra, that owns it.
It completed an expansion of the facility in 2023, adding more than 110,000 battery modules needed to store renewable energy. Energy storage facilities like this one are essential for power grids to be able to keep enough excess solar and wind energy so it’s available when the sun goes down and winds wane.
The current blaze is unrelated to fires burning further south that have devastated Los Angeles County.
