sourceThe MONTEZUMA II project is a proposed 132 MW hybrid wind and battery energy storage project located in Solano County, California. The project consists of 78 MW of wind generation and a 54 MW battery energy storage system. Interconnection is with Pacific Gas & Electric (PGAE) within the California Independent System Operator (CAISO) region.
The project, identified as CAISO-222 in the CAISO interconnection queue, entered the queue on May 23, 2007, with a proposed commercial operation date of January 29, 2012. An Interconnection Agreement (IA) was executed on December 17, 2010. The point of interconnection is Birds Landing 230 kV. The project has been mentioned in recent news coverage.
