Completes construction, term, and tax equity financing for 1.04 GW / 2.76 GWh in projects, including largest single project financing to date for standalone storage.

Plus Power LLC announced completion of $1.8 billion in new financing for standalone battery storage, including the largest single such project financing to date, to help stabilize the U.S. electrical grid while incorporating more solar and wind energy.

The company, which leads the sector for developing, owning, and operating standalone energy storage wherever on the grid it is most needed, will use the capital to fund the construction and operations of five projects. Plus Power has a rapidly growing portfolio of large-scale lithium-ion battery systems in more than 25 states and Canada, and the company is executing on 10 gigawatts of interconnection capacity now in transmission interconnection queues.

Today's announcement includes Plus Power's $707 million financing for the 250 megawatt Sierra Estrella Energy Storage facility in Avondale, Arizona, west of Phoenix. It will be the largest to date for a standalone energy storage project. The 11-acre footprint of the Sierra Estrella project allows the project to be sited without attached generation, closer to load.

The announced transactions are also supporting construction of 700 megawatts of batteries on the ERCOT grid in Texas. Three new Plus Power battery plants will begin operation by next summer to handle increased demand amid increasingly extreme temperatures and numerous days of scarce operating reserves on the power grid.

For example, as this year's summer heat waves triggered record demand for electricity, Plus Power's existing 100-megawatt Gambit Energy Storage facility in Angleton, Texas, repeatedly provided energy and ancillary grid services (such as regulation up and down, contingency reserve, and frequency response) to help grid operators stabilize the power system and avert a blackout.

The financing commitments announced today cover five projects totaling 1,040 megawatts of capacity (or 2,760 megawatt-hours). The transactions will support both construction and operations of the portfolio and include construction financing, term financing, letters of credit, and tax equity investments, in partnership with 11 leading industry lenders and investors.

The size and breadth of the financings by leading institutions - and the projects' geographic and revenue structure diversity - highlights the variety of services and value that well-sited standalone energy storage can offer power markets.

"Over the last year, Plus Power has raised an unparalleled amount of capital for standalone storage projects from a wide range of leading energy project finance banks and investors," said Josh Goldstein, chief financial officer of Plus Power. "This capital will support the ongoing buildout of the largest and most diverse portfolio of standalone storage projects in the U.S. The scale highlights our first-mover advantage in bringing high-quality projects to market as well as the tremendous work by our fantastic team."

Goldstein added, "We deeply value our financing partners who support the construction and operation of our wide portfolio across the U.S., enabling decarbonization and the transition to a more efficient grid."

Among the completed transactions were construction, term, and tax equity financings totaling $884 million on three new standalone storage facilities in Texas. They bring Plus Power's current ERCOT portfolio to 800 MW, or 1,575 MWh. Deutsche Bank and First Citizens Bank were the coordinating lead arrangers, with First Citizens Bank as the administrative agent and Siemens Financial Services, Inc. acting as the joint lead arranger. They include:

$212.2 million of tax equity financing from Foss & Company, as well as $276 million of construction and term financing, for the 300 MW / 600 MWh Rodeo Ranch Energy Storage facility in Pecos.

$196 million of construction and term financing for the 200 MW / 400 MWh Ebony Energy Storage facility in Comal County, northeast of San Antonio.

$200 million of construction and term financing for the 200 MW / 400 MWh Anemoi Energy Storage facility in Hidalgo County, on the Mexican border northwest of Matamoros.
While the Ebony and Anemoi projects are expected to operate as merchant resources in the ERCOT wholesale market, Plus Power executed an innovative hedge for Goldman Sachs' commodities group for a portion of the Rodeo Ranch Energy Storage facility.

The Sierra Estrella project was one of two Plus Power landmark project financings in Arizona that totaled $903 million and 340 MW / 1,360 MWh. Both projects have 20-year energy storage services agreements with Salt River Project and are under construction, aiming to be online by the second quarter of 2024 in time for another summer of anticipated record peak demand. Norddeutsche Landesbank and Société Générale acted as coordinating lead arrangers while Mizuho, U.S. Bank, Bank of America, CoBank, and Siemens Financial Services, Inc. were joint lead arrangers. The financings include:

$202 million of tax equity for the 250 MW / 1,000 MWh Sierra Estrella Energy Storage facility in Avondale from Bank of America, coupled with a $505 million construction, term loan, and letter of credit facility.

$196 million construction, term loan and letter of credit facility for the 90 MW / 360 MWh Superstition Energy Storage project in Gilbert, southeast of Phoenix.
