FERC grants various approvals for 200-MW Imperial Valley Solar 1

The Federal Energy Regulatory Commission on May 31 issued an order that conditionally accepts and suspends, for a nominal period, an agreement related to the Imperial Valley Solar 1 LLC (ISV-1) project in California.

The proposed tariff would permit IVS-1 to make wholesale sales of electric energy, capacity, and ancillary services at market-based rates in the Southwest region. The commission, among other things, granted IVS-1 waiver of the obligation to file an Open Access Transmission Tariff (OATT), and to establish and maintain an Open Access Same-Time Information System (OASIS). It also granted IVS-1’s request for other waivers commonly granted to market-based rate sellers. 

Additionally, the commission found that IVS-1 meets the criteria for a Category 2 seller in the Southwest region and is so designated.

On March 21, as amended on April 17, IVS-1 filed an application for market-based rate authority with an accompanying tariff providing for the sale of electric energy, capacity, and ancillary services at market-based rates in the markets administered by the California Independent System Operator (CAISO).

IVS-1 will own a 200-MW solar photovoltaic facility located in Imperial County, Calif. All of the output from the facility, which is due for operation around July 1, will be sold to San Diego Gas & Electric (SDG&E) under a 25-year power purchase agreement. 

This facility will represent the first of four phases of a 600-MW photovoltaic facility.

  • Imperial Valley Solar 2 LLC will own the second phase (150 MW of capacity expected to begin commercial operation by Dec. 31, 2015).
  • Imperial Valley Solar 3 LLC will own the third phase (150 MW of capacity expected to begin commercial operation by March 31, 2016).
  • Imperial Valley Solar 4 LLC will own the fourth phase (100 MW of capacity expected to begin commercial operation by June 30, 2016).

IVS-1 said that all of these companies have entered into a Large Generator Interconnection Agreement (LGIA) Co-Tenancy Agreement dated September 2012, pursuant to which each company and Imperial Valley Solar LLC share in the rights and responsibilities under the LGIA.

IVS-1 said that it is a wholly-owned, indirect subsidiary of AES Solar Power LLC, which is a joint venture between AES Corp. (NYSE: AES) and Riverstone Holdings LLC. IVS-1 said that it owns and controls, or is affiliated with, a total of 4,595 MW of installed capacity in the CAISO market.

Said the AES website: “AES Solar, established in 2008 as a joint venture between The AES Corporation and Riverstone Holdings LLC, develops, finances, constructs, owns and operates utility-scale solar photovoltaic (PV) projects globally. AES Solar currently has 233 MW of projects in Europe and Asia and has a pipeline of projects under development in the U.S., Europe and Asia.”
