Greylock Power installs a whole-home battery at no cost to you. We handle everything — installation, maintenance, monitoring. You get reliable backup power when the grid goes down.
No upfront costs, no monthly fees, no complicated contracts. We install and own the battery — you host it.
Email us your address. We confirm your home qualifies — most Connecticut homes do.
Our licensed electricians install and commission a whole-home battery system. Usually one day.
Greylock Power remotely manages the battery to support the local grid during peak demand.
When the grid goes down, your lights, heat pump, and fridge keep running — automatically.
Greylock Power earns revenue through state clean energy programs. Your home hosts the battery. You get the benefits.
Keep your entire home running during outages — not just a few circuits. Heat pump, fridge, lights, everything.
We pay you an annual fee for hosting the battery on your property. No work required on your end.
We monitor, maintain, and repair the system for the life of the agreement. Nothing to manage.
A straightforward hosting agreement. You own your home; we own the battery. No liens, no complications.
The CT Green Bank, Eversource, and United Illuminating fund energy storage that reduces strain on the grid during peak demand. Greylock Power captures those incentives and passes the benefit to homeowners as free backup power — particularly in communities that experience the most outages.
See if your home qualifiesWe work with community organizations and local governments to bring backup power to the households that need it most.
If you work with low-income households, public housing, or underserved neighborhoods in Connecticut, we'd like to talk. We're actively seeking community partners for our initial deployments.
Start a conversationWe know "free" raises questions. Here are the most common ones.
Connecticut utility programs pay incentives for batteries that help stabilize the grid during peak demand. That revenue funds our operations — and we pass the benefit to you as free backup power.
Greylock Power owns and is responsible for the battery at all times. It does not become part of your home. There is no impact on your property taxes or title.
The battery detects the outage and automatically switches your home to battery power within milliseconds. No action needed on your part.
A multi-year hosting agreement, similar to a residential solar lease. We'll walk you through the terms before you sign anything.
The agreement can transfer to a new owner, or we can work with you on a transition. We handle the logistics.
Most Connecticut homes with a standard electrical panel qualify. Email us your address and we'll confirm within a day or two.
