Ameresco Announces Completion of Multiple Financing and Tax Credit Transfer Transactions

The facility with Counterpointe SRE and Barings has streamlined Ameresco’s execution of multiple financings, driving consistency and scale across an expanding pipeline of large-scale energy storage and solar‑plus‑storage projects.

Under this platform Ameresco has executed a series of strategic financing and ITC sales transactions that reinforce the Company’s capability to pair long‑term debt solutions with the sale of associated transferable tax credits to help accelerate the deployment of advanced battery energy storage and solar PV infrastructure. Recently closed transactions under the shelf and ITC sales platforms include:

• the sale of ITC generated from the completion of a 50 MW / 200MWh BESS project by Ameresco’s development team, which was previously financed with long-term debt through the issuance of Series A notes under the shelf facility;

• the financing of a 12MW solar and 10MW / 50MWh BESS project with long‑term debt through the issuance of Series B notes under the shelf facility and concurrent sale of the associated ITC; and

• the financing (including an ITC bridge financing) of a 25MW / 100MWh BESS project with long-term debt through the issuance of Series C notes under the shelf facility. Ameresco expects to monetize the related ITC upon commercial operations of the BESS project and will use the proceeds to repay the bridge financing.

“These newly completed transactions mark another important step in our strategy to deploy long‑duration, flexible capital solutions that support the rapid expansion of solar and advanced energy storage infrastructure across the country,” said George Sakellaris, President & CEO of Ameresco. “The versatility of the CounterpointeSRE/Barings private shelf facility enables us to efficiently finance a diverse range of assets while helping our customers advance their resilience, reliability, and decarbonization goals. We look forward to continuing to execute additional transactions under this structure as we scale our development pipeline.”

“These transactions demonstrate the value of a scalable financing platform that supports the continued build-out of energy storage and solar infrastructure,” said Eric Alini, CEO of CounterpointeSRE. “Ameresco has shown a strong ability to combine project execution with disciplined capital structuring, and we are pleased to partner with both them and Barings to provide long-term financing solutions that incorporate transferable tax credits. This platform accelerates the deployment of capital to high-quality energy transition assets across the U.S.”

“Barings is proud to partner with CounterpointeSRE in supporting Ameresco through a platform that brings consistency and efficiency to financing large scale storage and solar assets,” said Stephen Coscia, Managing Director, Global Infrastructure Debt at Barings. “These transactions reflect our commitment to delivering long-term capital solutions that advance critical energy infrastructure across the country, while positioning Barings to deliver attractive risk-adjusted returns to our investors.”
