IRVING, Texas — July 11, 2022 — Vistra released the following statement:

Vistra’s Moss Landing Energy Storage Facility has successfully restarted with more than 98% of its 400-megawatt capacity now storing and releasing power to the California grid for the all-important summer season.

The company began incrementally bringing the facility online throughout May and June after implementing identified corrective actions, including related to connectors in the water-based heat suppression system.

The remaining 7 MW will be restored later this summer once replacement batteries and electrical components are received.

Vistra continues to work with regulators and state and local officials as it completes the restoration work.

Vistra’s Moss Landing Energy Storage Facility consists of two separate buildings – one housing the 300-MW Phase I system and the other housing the 100-MW Phase II system. Construction is underway on the 350-MW Phase III expansion, which is set to be commercially operational next summer. A potential fourth phase could eventually expand the site’s capacity to 1,500 MW – enough to power approximately 1.125 million California homes.

Statement issued May 9, 2022:

Vistra expects to have a substantial portion of its 400-megawatt Moss Landing Energy Storage Facility back online for summer, with the entire facility operational during the summer. With corrective actions determined and implementation nearing completion, including replacement of connectors in the water-based heat suppression system and testing, the company anticipates it will have 200 MW available in early June, with another 150 MW coming online incrementally throughout the month. The remaining 50 MW are anticipated to become operational in August as we receive replacement batteries and complete installation.

Vistra continues to work with regulators and state and local officials as it completes the restoration work comprehensively, properly, and safely.
