FERC approves new interconnect deal for Mesquite Solar 1

The Federal Energy Regulatory Commission on Nov. 26 accepted the California Independent System Operator’s Sept. 30 filing of a Large Generator Interconnection Agreement (LGIA) for a 165-MW solar facility.

The LGIA is among CAISO, project developer Mesquite Solar 1 LLC and San Diego Gas & Electric (SDG&E). The Mesquite Solar LGIA provides for the interconnection of a 165-MW solar photovoltaic facility located near Arlington, Ariz. CAISO also noticed termination of the pilot Pseudo-Tie Participating Generator Agreement between Mesquite Solar and CAISO, effective February 2012. 

Sempra U.S. Gas & Power and Consolidated Edison Development recently became equal partners in two of Sempra U.S. Gas & Power’s solar facilities; the 150-MW Copper Mountain Solar 2 near Las Vegas and Mesquite Solar 1. Under the terms of the joint-venture agreements, which were announced in May, each company will own a 50% interest in each of the solar facilities. The terms of the transaction were not disclosed.

Mesquite Solar 1, the first phase of Sempra U.S. Gas & Power’s Mesquite Solar complex located in Arlington, Ariz., was completed in late 2012. Power from the facility has been fully sold to Pacific Gas & Electric under a 20-year contract.
