Mesquite Solar 3 files co-tenancy deal for Arizona solar projects

Mesquite Solar 3 LLC filed with the Federal Energy Regulatory Commission on Aug. 1 an LGIA Co-Tenancy Agreement (Mesquite CTA) dated May 10, 2016.

The parties to the Mesquite CTA are Mesquite Solar 3 (MS3), SEP II LLC and SGS Development LLC. The Mesquite CTA relates to the rights and responsibilities of the parties under the Large Generator Interconnection Agreement (Mesquite LGIA) dated as of April 19, 2016, by and among MS3, SEP II, SGS, the California Independent System Operator (CAISO) and San Diego Gas & Electric (SDG&E).

MS3 owns a solar photovoltaic (PV) facility currently under construction that is located in Maricopa County, Arizona, in the vicinity of the Hassayampa switchyard. MS3 is authorized to make wholesale sales of electricity at market-based rates, has received waivers commonly granted to market-based rate sellers, and is an exempt wholesale generator (EWG). SEP II holds real estate interests and permits associated with future development of solar PV generation in the vicinity of Hassayampa, and is authorized to sell wholesale energy, capacity and ancillary services at market-based rates, and has received waivers commonly granted to market-based rate sellers. SEP II and MS3 are party to two shared facilities agreements (Mesquite SFAs) governing their respective pro rata ownership – along with adjacent generators – of certain shared generator interconnection facilities (Shared Facilities) connecting to Hassayampa.

SGS, which does not own or control generation or transmission facilities, may in the future become party to the Mesquite SFAs in the event SGS develops a generation facility that makes use of the shared facilities.

The phases to be constructed, owned and operated by each of the CoTenants are projected to have a net nameplate capacity of 152 MW for Mesquite Solar 3 and a combined net nameplate capacity of 218 MW for SEP II and SGS Development.
