California ISO files interconnect deal for 165-MW Mesquite Solar 2 project

The California Independent System Operator filed on Aug. 21 at the Federal Energy Regulatory Commission an executed Large Generator Interconnection Agreement (LGIA) with San Diego Gas & Electric (SDG&E) and project developer Mesquite Solar 2 LLC for a 165-MW facility due in commercial operation in late 2016.

The LGIA provides for the interconnection of the Mesquite Solar 2 solar photovoltaic facility located in Maricopa, Arizona. The Mesquite Solar 2 LGIA contains deviations from the CAISO pro forma LGIA that are substantially identical to those previously accepted by the commission in another interconnection agreement for a solar project that also utilizes existing connections to the Hassayampa Switchyard while being included in the CAISO’s Balancing Authority Area. Specifically, precedent for the Mesquite Solar 2 LGIA was established by the Mesquite Solar 1 LLC project in 2013.

Mesquite Solar 2 will utilize an existing interconnection comprised of two 500 kV generation tie lines between the Hassayampa Switchyard and the Mesquite 230/500 kV Switchyard.

Mesquite Solar 2 has elected for this 165-MW solar photovoltaic Large Generating Facility to have Full Capacity Deliverability Status, as such term is defined in the CAISO Tariff.

The targeted commercial operation date for the project is Nov. 30, 2016.

A project contact listed in the LGIA is: Mesquite Solar 2 LLC c/o David Grazda Director-Asset Management, Sempra U.S. Gas & Power LLC, 488 8th Avenue, HQ11S3, San Diego, CA 92101, Phone: (619) 696-4480, Fax: (619) 696-4096. dgrazda@semprausgp.com.
