Vistra Energy has welcomed the enactment of clean energy policies in Illinois which the power generation company said will support 300MW of solar and 150MW of battery storage to be built at nine of its coal plant sites. 

Augmentation at the Vistra Moss Landing Energy Storage Facility in California has been completed, with the world’s biggest battery energy storage system (BESS) now at 400MW / 1,600MWh. 

US power generation holding company Vistra has renewed its call for legislation designed to assist the transition from coal to renewable energy in the US state of Illinois.

A proposal by Pacific Gas & Electric (PG&E), one of California’s three main investor-owned utilities (IOUs) to deploy large-scale energy storage to replace peaking natural gas plants has been approved by the state’s regulator.
