12 May 2022

Ameresco Inc. (NYSE:AMRC), a leading cleantech integrator, and Powin LLC (Powin), a global leader in the design and manufacture of safe and scalable battery energy storage solutions, announced that they have signed a long term non-exclusive purchasing framework agreement for Powin to supply Ameresco with 2,500 MWh of its modular BESS Stack750 product as part of its Centipede hardware platform.

The long-term purchase agreement is intended to supply a portion of Ameresco’s BESS needs through mid-2025 and be utilized in Ameresco’s project and asset installations for a wide array of customers ranging from small municipal utilities to large Federal projects. Ameresco chose Powin’s system because the modular design of the Stack750 product is well suited for a variety of Ameresco’s customer needs and requires decreased lead time to deploy, reduced space on-site, and a lower overall capital cost.

“Building on our experience with BESS projects across the globe, we are excited to agree to this supply to help meet our growing demand for battery energy storage technologies as a part of our comprehensive customer solution set,” said Doran Hole, EVP and Chief Financial Officer, Ameresco. “As costs have declined and the technology matured, battery storage has rapidly become a go to clean energy technology. Whether as a standalone system or as part of an integrated solar or microgrid solution, BESS have become an integral technology for customers looking to increase energy resiliency and reliability. This agreement is designed to bolster our BESS availability with a high quality, flexible product and offer advantageous equipment delivery timelines to support our growing base of customers throughout our various vertical markets.”

Earlier this year, Powin announced that it will produce its Centipede platform in North America, further supporting Powin’s ability to navigate supply chain challenges and ensure its customers have the products needed to execute projects. Powin is uniquely positioned to nearshore Stack750 manufacturing due to the company's vertically integrated business model, diversified supply chain and control over the product design. By owning the product design and manufacturing from the Energy Management System (StackOS) down to the Powin battery module, Powin has become an industry leader in BESS safety, product quality, deployment agility and project reliability, passing extraordinary value on to Powin customers like Ameresco.

Geoff Brown, CEO of Powin, stated, “Ameresco has built a reputation as a trusted partner of the U.S. government, major corporations, and utilities in deploying renewable energy projects and battery energy storage systems. We are pleased that the Ameresco has selected Powin as one of their partners as they expand their energy storage business. With our new North American production facility, we plan to provide Ameresco with both the advanced, modular and energy-dense hardware required for their use cases as well as the experience needed to navigate supply chain constraints.”

Over the past decade, Powin has worked to advance its patented battery management technology and develop market-leading product offerings. Headquartered in Oregon, Powin has built over 2,000 MWh of systems in 12 states and 8 countries. Powin has a contracted pipeline to supply over 5,800 MWh of energy storage systems globally over the next three years.
