• Platform has at least two projects awaiting clearance on NYSERDA’s ISC solicitation
• Taft project in Worcester, MA expected to commercialize later this year

Flatiron Energy formally launched a sales process, said the sources familiar with the situation.

Teasers for the process, known as Project Westfold, were recently distributed to the market.

Overall, NPM Interconnection queue data is tracking at least seven pre-operational projects, at just over 1.9 GW, across PJM, ISO-NE and NYISO.

The pipeline, behind that, is also all in the Northeast.

The company engaged Guggenheim Securities earlier this year to explore capital markets solutions.

Flatiron both secured a strategic investment from Hull Street Energy in July 2024, while securing a follow-on commitment from Hull Street in October 2025 and also upsizing its existing credit facility to USD 250m with HPS Investment Partners.

Hull Street, Flatiron Energy, and Guggenheim did not return calls seeking comment.

The company’s most advanced project has been the 200 MW / 800 MWh Taft project in Worcester County, Massachusetts that closed project financing September 2025 and is slated to commercialize later this year.

NPM SIGNALS, though, has also detected multiple bids that Flatiron has submitted into New York State Energy Research and Development Authority (NYSERDA) inaugural Index Storage Credit solicitation that is expected to be resolved soon as NYSERDA had been expected to announce contract awards during 2Q26.

Flatiron disclosed that its 123 MW / 492 MWh Battery Park Storage project in Kings County, New York and 123 MW / 492 MWh Palladium Storage project in Bronx County, New York were both vying for the ISC.
