This financial backing was a prerequisite for the company’s strategic evolution, providing the resources necessary to acquire and develop capital-intensive assets like the $80 million Bridgeport fuel cell park. The influx of capital signals strong investor confidence in the company’s vertically integrated model and its strategy to address the growing demand for distributed baseload power.

EQT’s Strategic Backing

In January 2025, global investment firm EQT acquired Scale Microgrids through its Transition Infrastructure fund. This transaction was the fund’s first North American investment, signaling a clear strategic intent to back companies building the next generation of energy infrastructure. EQT‘s support provides not just capital, but also strategic guidance and access to a global network, positioning Scale Microgrids to compete for larger and more complex projects.

Securing Project-Level Capital

By June 2025, Scale Microgrids announced it had surpassed $1 billion in total project financing to build out its pipeline. For the specific 9.6 MW Bridgeport project, the company secured debt financing from major institutions Investec and MUFG, along with tax equity from Foss & Co. This ability to secure project-specific, non-recourse financing from established lenders validates the commercial viability and bankability of its new fuel cell strategy and the underlying technology.

Scale Microgrids’ Hy Axiom and Investor Partnerships for 9.6 MW Project

Scale Microgrids assembled a consortium of technology suppliers and financial institutions to execute its first major fuel cell project, signaling a shift toward complex, multi-party project development. The successful orchestration of the Bridgeport project required deep collaboration with technology provider Hy Axiom for the core equipment, as well as a syndicate of financial partners to underwrite the $80 million investment. This partnership-heavy approach is essential for de-risking and executing large-scale, novel energy projects.

Hy Axiom Technology Integration

The Bridgeport project is built around 21 Pure Cell Model 400 phosphoric acid fuel cells supplied by Hy Axiom, a subsidiary of Doosan Corporation. This partnership provides Scale Microgrids with a mature and commercially proven fuel cell technology capable of delivering high-efficiency power and useful thermal energy. The selection of a veteran supplier like Hy Axiom mitigates technology risk and ensures the reliability required for a baseload power application.

Financial Consortium for Bridgeport

Bringing the Bridgeport project to financial close involved a strategic alliance with key financial players. Scale Microgrids worked with Nu Power LLC, the original project developer, to acquire the asset. It then structured a complex financing package with Investec and MUFG as lenders and Foss & Co. as the tax equity investor. This ability to marshal support from different corners of the financial industry is a core competency for developing capital-intensive infrastructure.

US Northeast Focus, Scale Microgrids’ Connecticut Fuel Cell Project

Scale Microgrids‘ strategic fuel cell initiative is centered in the U.S. Northeast, with the Bridgeport, Connecticut project serving as a key entry point into a region with high energy costs and a demand for resilient power infrastructure. While the company’s solar and storage portfolio has a wider national footprint, the deliberate choice of Connecticut for its first major fuel cell project highlights a strategy of targeting specific regional markets where the value proposition of clean, reliable, and locally-sited power is highest.

Connecticut as a Proving Ground

Connecticut and the broader New England region present an ideal market for CHP fuel cell projects. The area is characterized by high electricity prices, grid congestion, and a history of weather-related power outages, creating strong commercial and institutional demand for energy resilience. Furthermore, supportive state-level programs for clean energy have created a favorable policy environment for technologies like fuel cells, making it a logical location for Scale Microgrids to validate its expanded business model.

Targeting High-Value Regions

The Bridgeport project, which will provide power equivalent to 8, 500 homes and heat to the University of Bridgeport and 20 other facilities, is a template that can be replicated in other high-value regions. Urban centers, university campuses, hospitals, and industrial parks in areas with constrained grids are prime targets. By proving its ability to execute a complex CHP project in the Northeast, Scale Microgrids develops the credibility and operational experience needed to expand this model to other target markets across the country.
