Vermont replacing power plants with home batteries
Green Mountain Power in Vermont is leasing home batteries to thousands of customers, creating a virtual power plant that provides emergency backup and replaces fossil-fuel peaker plants.
summary is enough The article covers a compelling real-world virtual power plant deployment, but technical readers can grasp the core model quickly without reading the full piece.
summary
Green Mountain Power, Vermont's largest utility, runs a program that installs home batteries in thousands of residences for a monthly fee. These connected batteries act as a virtual power plant, providing individual homes with resilient backup during severe storms while allowing the utility to smooth peak energy demand. This distributed network has successfully replaced multiple fossil-fuel peaker plants and now functions as the state's largest power source. However, scaling the model nationwide faces hurdles including utility financial incentives, regulatory building codes, and hardware costs.
key points
- Green Mountain Power's virtual power plant provides about 110MW of capacity, making it Vermont's largest power source and allowing the utility to decommission multiple fossil-fuel peaker plants.
- Customers pay a monthly lease fee for home batteries, gaining reliable backup power during extreme weather while the utility manages the stored energy during peak grid demand.
- Commenters and energy experts debate the underlying economics, noting concerns about upfront consumer costs, utility cost-shifting, and safety/building code restrictions for battery placement.

discussion mixed
consensus
Commenters generally see virtual power plants as a smart way to handle peak demand and smooth the duck curve, but many express skepticism about the financial structure, arguing that utilities are shifting infrastructure costs onto consumers.
pushback
Some commenters raise serious concerns about the fire risks and strict building code restrictions associated with home-installed lithium batteries, suggesting traditional generators are often more practical.
I'd feel better about this if they weren't charging people thousands for the batteries. As it is, this looks like a scam by utility companies to force their costs onto consumers and charge them for it on top of that. People should be being paid by the utility for storing, hosting, and allowing access to the power company's distributed infrastructure.
It's not as if the batteries people are paying for become their property, or are only for the homeowner's benefit. The utility company has the right to use that power however they want at any time including the "right to use all the energy in …
It articulates the critical pushback that users are paying for infrastructure that primarily benefits the utility while giving up privacy and property access.
