Enel, through its subsidiary Enel Green Power North America, has signed an agreement to acquire a portfolio of seven operational photovoltaic plants in the United States totalling approximately 270 MW. The assets are being acquired from a US utility for around USD $140 million, with an expected positive contribution of roughly USD $20 million per year to ordinary EBITDA. The portfolio includes projects across Virginia, North Carolina, and South Carolina, marking Enel’s entry into these states and expanding its US renewable footprint.

Hull Street Energy, a private equity firm, has signed an agreement to acquire FirstLight from the Public Sector Pension Investment Board, in a deal covering nearly 1,400 MW of energy assets. The portfolio includes the 1,168 MW Northfield Mountain pumped storage hydro facility in Massachusetts, New England’s largest energy storage asset, alongside three operational solar and battery sites and 14 hydroelectric stations across Connecticut, Massachusetts, and Pennsylvania.

GridStor, backed by Goldman Sachs, acquired the 199MW / 796 MWH Birdseye battery energy storage project in Adams County, Colorado from Accelergen, marking its fifth acquisition within the last eighteen months. The project is set for construction to begin as early as 2027, with commercial operations planned for the end of 2028. Once operational, the facility is expected to provide power equivalent to serving over 150,000 households during periods of highest demand.

Frontier Power USA, a long-duration energy storage development and investment company, has signed a transaction to acquire a 480 MWh portfolio of BESS development projects from Bimergen Energy Corporation. The portfolio includes three ERCOT-based projects, including two “Texas 10” projects and a 100 MW / 400 MWh project with Notices-to-Proceed expected in mid-2026. The deal marks FPUSA’s first acquisition under its GWh capacity reservation agreement with Eos Energy Enterprise and will utilize Eos’ Z3 long-duration battery systems. FPUSA will fund 100 percent of construction equity and is expected to hold a 92.5 percent ownership stake in the project companies following contribution, with Bimergen retaining a 7.5 percent economic interest. 

US fusion startup Thea Energy has raised $100 million to develop its Eos demonstration system, a stellarator-based nuclear fusion device designed to generate carbon-free electricity. The funding round included US Innovative Technology, General Innovation Capital Partners, and Prelude Ventures, which previously backed the company in 2024. Thea was spun out of Princeton Plasma Physics Laboratory in 2022, giving the company deep roots within the broader Princeton University research ecosystem. The company plans to begin construction on the system next year, targeting completion by 2030 and commercial deployment by approximately 2034. The raise comes as investor interest in fusion accelerates alongside rising electricity demand from AI data centers, electrification, and industrial power consumption.

Austrian cleantech startup REPS has raised $23.6 million in equity financing to scale its Road Energy Production System, a patented “road power plant” that converts vehicle traffic into electrical energy. Based in Tyrol, Austria, the company installs its technology directly into existing road infrastructure, harvesting energy from trucks and cars without disrupting traffic flow. REPS is initially targeting ports, logistics hubs, industrial sites, and cities looking to lower energy costs while improving sustainability. The company says its system has already generated more than 6,700 kWh of electricity from real traffic conditions within six months of deployment and claims efficiency levels significantly above competing energy harvesting technologies.

Energy software startup Texture has raised $12.5 million in Series A funding led by VoLo Earth and Equal Ventures, with participation from existing investors Lerer Hippeau and Abstract Ventures. The company is building what it calls an operating system for the energy grid, helping utilities, hardware OEMs, and grid services companies unify fragmented operational data into a single platform. Texture’s software enables utilities to monitor grid assets, manage outages, dispatch distributed energy resources, and operate demand response programs from one system. The raise comes as utilities face mounting pressure from rising electricity demand, data center growth, EV adoption, and increasingly complex distributed energy networks.
