Vermont's Green Mountain Power Replaces Traditional Plants with Home Battery Virtual Power Plant
Key points
- GMP installed home batteries for $55/month over 10 years.
- Over 5,500 Vermont homes use these battery systems.
- The virtual power plant is now Vermont's largest power source.
- US virtual power plant capacity could reach 160GW by 2030.
Vermont's Shift to Distributed Energy
Green Mountain Power (GMP), Vermont's largest utility, has implemented a program that replaces traditional power generation with a network of home battery systems. This initiative has led to a virtual power plant becoming the state's largest power source, demonstrating a shift towards distributed energy resources.
The program offers participants two home batteries for a monthly fee of $55 over a 10-year lease agreement. This alternative proved more cost-effective for some residents than purchasing a gas generator, which can cost around $12,000.
Benefits for Residents and Grid Stability
For individual homeowners, the battery systems provide energy security, protecting them from power outages, which have become more frequent due to extreme weather events in Vermont. Participants report not losing power since installation.
Collectively, these over 5,500 home battery systems form a virtual power plant, mimicking the capabilities of a traditional power plant. This network enhances grid resilience and provides a cleaner energy source for the state.
National Implications and Growth
The success in Vermont reflects a broader trend in the United States. According to Wood Mackenzie, the US currently has over 40GW of virtual power plant capacity. While this is still smaller than traditional fossil fuel sources, a 2025 US Department of Energy report projects that capacity could expand to 160GW by 2030.
This projected growth would equate to approximately 20% of the country's expected peak energy demand, indicating a significant role for virtual power plants in the future energy landscape.
