Mesquite Solar files shared grid deal for Arizona solar projects

Mesquite Solar 1 LLC on Dec. 15 filed with the Federal Energy Regulatory Commission an Amended and Restated Co-Tenancy and Shared Facilities Agreement that covers one existing and other future solar projects in Arizona.

The parties to this Restated Inter-Phase SFA are Mesquite Solar 1, Mesquite Solar 2 LLC, Mesquite Solar 3 LLC, SEP II LLC and Sempra Global Services (SGS). The agreement governs the terms and conditions under which the parties will own, utilize, operate, and maintain their interests in a 34.5/230kV substation and a 230kV generation-tie line that is approximately four miles in length, which are limited and discrete facilities used solely to connect generating facilities to the grid.

Each of the parties to the Restated Inter-Phase SFA is a wholly- or partially-owned indirect subsidiary of Sempra Energy.

  • Mesquite Solar 1 owns a solar photovoltaic facility located in Maricopa County, Arizona, in the vicinity of Hassayampa and interconnected to the grid via the Mesquite Solar Generator-tie Facilities, which in turn connects to additional shared facilities that Mesquite Solar 1 owns jointly as a tenant-in-common with Mesquite Solar 2, Mesquite Solar 3, SEP II, Mesquite Power LLC and The Salt River Project Agricultural Improvement and Power District (SRP). 
  • SEP II holds real estate interests and permits associated with future development of solar photovoltaic generation in the vicinity of Hassayampa. SEP II 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 will assign to MS2 and MS3 a portion of SEP II’s undivided interests in the Mesquite Solar Generator-tie Facilities.
  • MS2 and MS3 are developing solar photovoltaic facilities adjacent to the MS1 facility and approximately 100 MW and 152 MW in size, respectively. MS2 and MS3 will sell the output of their facilities to unaffiliated wholesale buyers under long-term power purchase agreements.
