Insights

Energy Systems Strategist

Partnership expands utility-scale home storage deployment in Vermont and adds clear, monitorable customer pricing and product timelines.

The deal pairs Enphase hardware and services with Green Mountain Power distribution and customer reach, using leased IQ® Battery 10C systems to grow a 75 MW virtual power plant and provide customer-level backup and grid services. The business mechanism is straightforward: GMP secures distributed capacity and resilience while customers access storage through a ten-year lease at $55 per month or a one-time payment of $5,500, and Enphase supplies equipment, warranty, monitoring, and operations support.

Dependencies and risks are explicit and narrow: program value relies on sustained deployment and dispatch of the leased batteries into the 75 MW VPP, customer uptake of the lease terms, and timely delivery of the IQ Battery 10C units and the IQ Bidirectional EV Charger expected in 2026. Warranty, 24/7 service, and domestic manufacturing claims address operational risk, but program success still depends on enrollment rates and effective VPP dispatch to reduce costs for all customers.

Concrete items to watch within the next 12–24 months include enrollment pace versus planned VPP growth, actual dispatch volumes contributing to the 75 MW capacity, first shipments and deployment metrics for IQ Battery 10C units sourced domestically, and the commercial launch of the IQ Bidirectional EV Charger in 2026.

FREMONT, Calif., Nov. 12, 2025 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company and the world's leading supplier of microinverter-based solar and battery systems, today announced a new partnership with Green Mountain Power (GMP) in Vermont to launch innovations benefitting customers through technology and grid transformation. GMP selected Enphase to join its groundbreaking home battery lease program where customers have back up power when they need it and share stored energy during peak usage times so GMP can reduce costs for everyone.

“We’re thrilled to partner with Enphase to bring cutting-edge technology directly to our customers – strengthening the grid, improving reliability, and driving down costs,” said Mari McClure, president and CEO of GMP. “These innovative solutions are already helping customers stay powered through increasingly severe storms and grid events. We’re expanding access so more people can enjoy true energy independence and resilience, transforming the grid into a dynamic, two-way system – interconnected, adaptable, and stronger together.”

GMP’s battery lease program is a significant part of its growing 75 MW virtual power plant, which is now Vermont’s largest dispatchable energy source and peaking plant, helping to reduce costs for all GMP customers while boosting resiliency and grid flexibility. GMP and Enphase also expect to partner in bringing Vermonters the latest innovations, including access to Enphase’s bidirectional electric vehicle charger. The IQ® Bidirectional EV Charger is expected to launch in 2026 and will enable electric vehicles to power homes if the grid is down or send power to the grid during peak demand, adding another form of energy storage to GMP’s growing suite of flexible home energy offerings.

GMP’s battery lease program will offer eligible customers a ten-year lease of two IQ^® Battery 10C™ systems at $55 per month or a one-time payment of $5,500. All products in the 4th-generation Enphase^® Energy System – including the IQ Battery 10C, IQ^® Meter Collar, and IQ^® Combiner 6C – come with Enphase’s industry-leading 15-year warranty, 24/7 customer service, and access to the Enphase^® App for advanced system performance monitoring. Enphase also recently announced first shipments of the IQ Battery 10C supplied from manufacturing facilities in the United States that meet the new domestic content requirements.

“We are pleased to be selected by Green Mountain Power, one of the nation’s most innovative utilities, to help create a cleaner, more resilient, and reliable grid for Vermont,” said Badri Kothandaraman, president and CEO of Enphase Energy. “Our IQ Battery systems feature advanced technology that is being deployed by utilities around the world as a flexible tool to create value for both their grids and the homeowners they serve.
