WattsOn
Connecticut

Your neighbors lose power.
You lose nothing.

Whole-home backup from $79 a month, fixed. No equipment to buy.

Connecticut's battery program pays at today's rate only until the current block fills. Blocks step down, never up. The rate you lock is the rate you keep.

Illustrative program mechanics; live block status arrives with the per-address API.

Why is the price this low?

Estimates, not guarantees. Final plan by address.

Watch it work.

Cheap hours, expensive hours, and the moment the grid goes out.

One night in February

The storm knocks out the grid at 2:14 AM.

Here's what happens in your house. Which is to say: nothing.

The grid goes down. Your battery takes over in less time than a blink.

The fridge keeps humming. Two hundred dollars of groceries stay cold.

Rain keeps falling. The sump pump keeps pumping. The basement stays dry.

The baby monitor never drops. The WiFi never blinks. Everyone sleeps.

You wake up to coffee and a phone notification: "Your home ran on backup last night." That's how you find out.

Why is the price this low?

Fair question. Your battery does two jobs. It backs up your home, and at the grid's hardest moments it lends a hand, and the utility pays for that help. That payment is built into your flat price. Your backup always comes first, and you can see every event in the app.

How we can promise this.

Because before you ever typed your address, we already knew the neighborhood. All from public records and utility filings. Nothing about you personally, everything about the home.

Your rates. Which utility serves your address and what you pay at peak.
Your outages. What actually happened on streets like yours, how long, how often.
Your programs. What your utility pays battery owners, built into your flat price.

Who's behind WattsOn.

WattsOn is the consumer service from 257, an energy-data company. We map how homes across Massachusetts and Connecticut use, lose, and pay for power, and battery campaigns across the Northeast already run on that data. WattsOn turns it into a simple promise: your lights stay on, for one flat price, installed and maintained by licensed local crews. We never sell your address.

A real quote for your home: the system, the price, the install date. And if a battery is not a good fit for your home, we say so.

3
We install and maintain everything

Permits, install, monitoring, service. You don't lift a finger. Once you say yes, your installer calls to schedule. That is the only call.
