- Renewables developer Intersect Power has brought a 310MWp PV, 448MWh energy storage system project online in California.
- The Athos project is part of a near-term portfolio for Intersect, which totals 2.2 GW of solar PV and 1.4 GWh of co-located energy storage, the remainder of which will be operational in 2023.
Intersect Power, a Renewable energy developer, has brought a 310MWp PV, 448MWh energy storage system project online in California. The company announced the 22 December 2022 start of commercial operations for its Athos III solar project in Riverside County last week. The solar PV used for the project can generate a maximum of 224MWac/310MWp of solar energy, and the project features a 112MW/448MWh battery energy storage system (BESS), a four-hour unit. Energy storage projects need to have a discharge duration of four hours to participate in Resource Adequacy, grid operator CAISO’s framework for ensuring enough energy supply to meet demand.
The Athos project is part of a near-term portfolio for Intersect, which totals 2.2 GW of solar PV and 1.4 GWh of co-located energy storage, the remainder of which will be operational in 2023. The company secured US$2.6 billion of project financing in November 2021, as reported for the units, which will all be located in California and Texas.
The Athos project, also called the Blythe Mesa solar, was built on land owned by the federal agency Bureau of Land Management (BLM). Intersect is also developing another solar-plus-storage project on BLM land, which features a 500MW battery system. The mix of debt, tax equity and financing commitments was provided or arranged by HPS Investment Partners, Morgan Stanley Renewables Inc, MUFG, Santander Corporate & Investment Banking, Cobank, KeyBanc Capital Markets, Helaba, and Nord LB. The Athos project will meet the domestic content and prevailing wage requirements in the Inflation Reduction Act (IRA) to benefit from tax credits on the energy produced. It was initially developed by RRG Renewables, from which Intersect acquired it in 2020 at early-stage development before starting construction the following year.
