sPower divides 330-MW California solar project into 11 phases

Southern California Edison on April 25 filed with the Federal Energy Regulatory Commission a First Amended Large Generator Interconnection Agreement that divides a major solar project into 11 sub-projects.

The Amended LGIA is among Elevation Solar C LLC, Western Antelope Blue Sky Ranch B LLC, Antelope Big Sky Ranch LLC, Summer Solar LLC, Antelope DSR 1 LLC, Antelope DSR 2 LLC, Antelope DSR 3 LLC, Solverde 1 LLC, Bayshore Solar A LLC, Bayshore Solar B LLC and Bayshore Solar C LLC, and with the California Independent System Operator.

In September 2014, SP Antelope DSR LLC, CAISO and SCE entered into the Original LGIA. The Original LGIA was accepted for filing by the FERC in a letter order dated Dec. 17, 2014.

Subsequently, the project company requested and the CAISO and SCE agreed to amend the Original LGIA to: change the project name from SP Antelope DSR Project to Big Sky Solar Project; increase the number of phases for the project from two to eleven; increase the number of main transformer banks from two to nine to support the eleven proposed phases; and reflect eleven co-tenants instead of one tenant.

The project phases now are: 

  • Phase 1: 40 MW (gross) of the Big Sky Solar Project.
  • Phase 2: 20 MW (gross) of the Big Sky Solar Project.
  • Phase 3: 20 MW (gross) of the Big Sky Solar Project.
  • Phase 4: 20 MW (gross) of the Big Sky Solar Project.
  • Phase 5: 5 MW (gross) of the Big Sky Solar Project.
  • Phase 6: 50 MW (gross) of the Big Sky Solar Project.
  • Phase 7: 85 MW (gross) of the Big Sky Solar Project.
  • Phase 8: 20 MW (gross) of the Big Sky Solar Project.
  • Phase 9: 20 MW (gross) of the Big Sky Solar Project.
  • Phase 10: 20 MW (gross) of the Big Sky Solar Project.
  • Phase 11: 30 MW (gross) of the Big Sky Solar Project.

The Amended LGIA covers a new, approximate 0.2-mile, 220-kV generation tie-line from the Big Sky Solar Project site to SCE’s Antelope Substation. For purposes of this agreement, the generation tie-line will be referred to as the Antelope-Big Sky 220 kV Transmission Line.

The commercial operation target dates for the phases are:

  • Phases 1-4 (100 MW), June 30, 2016;
  • Phases 5-7 (140 MW), Oct. 31, 2016; and
  • Phases 8-11 (90 MW), Dec. 31, 2016.

The contact for all 11 project companies is: Adam Foltz, Director of Interconnection and Transmission, Afoltz@SPower.com, 2180 South 1300 East, Suite 600, Salt Lake City, UT 84106. That is contact information for Sustainable Power Group (sPower).
