About

The Mulqueeney Ranch Wind project is a proposed 114 MW wind generation project located in Alameda County, California. The project is being developed within the California Independent System Operator (CAISO) region and interconnects with Pacific Gas & Electric (PGAE) at the Tesla 230 kV point of interconnection.

The project entered the CAISO queue as queue ID CAISO-1277 on May 2, 2016. The interconnection agreement (IA) was executed on July 25, 2018, and the proposed commercial operation date (COD) is June 1, 2026. The project's interconnection status is currently listed as active.
