About

The Wright Solar project is a proposed 280 MW hybrid solar and battery energy storage project in Merced County, California. The development project consists of a 200 MW solar photovoltaic component coupled with an 80 MW battery energy storage system. It is interconnected to the CAISO grid under queue ID CAISO-779, with an interconnection request date of March 31, 2011, and a proposed commercial operation date of October 21, 2026. The project's interconnection agreement was executed on March 21, 2014.

The project is connected to the Los Banos-Panoche #1 230kV Line. Wright Solar has been the subject of recent news coverage, with 25 articles appearing in the press.
