Software that decides when your home battery charges and when it powers your home.
Kettle Energy is developing software that manages home batteries: charging when electricity is cheaper and more plentiful, and supplying the home when it is needed most. We are setting up our first pilots with UK housing associations. Talk to us if you work for a housing association and want to take part.

A smart way to match energy with demand.
- 1
Clean electricity is not always used when it's generated.
Wind and solar output can exceed what the country needs at that moment — for example, on a windy night. When that happens, the price of electricity tends to fall.
- 2
Supply and demand do not always line up.
The network cannot always move that electricity to where it's needed, so some clean generation is turned down or switched off. Keeping supply and demand balanced at every moment is the job of the National Energy System Operator (NESO).

Kettle's software decides when to store and when to use.
Kettle's software is being built to weigh up electricity availability, time of day and expected household demand, all of which affect cost. It tells a home battery when to charge and when to supply electricity to the home.

Homes draw on stored electricity at cheaper times.
In a pilot, households would draw on stored electricity when they need it most, which is usually when demand — and prices — are higher. The aim is to reduce both waste and cost.
Why battery storage could help
Matching cleaner electricity with the moments homes need it.
Follow a typical day. Kettle's AI platform identifies opportunities to shift energy use and coordinate connected home batteries between periods of availability and demand.
01:00 · Overnight
Wind blows while the country sleeps
Generation is high and demand is low. This is the cheapest, cleanest electricity of the day — and the moment fewest people are using it.
Battery charging · 37% stored
- Clean electricity available
- What homes use
- Surplus that could be shifted
- Stored in the battery — 37%

The Kettle platform
How the software works.
Kettle brings together electricity prices, weather and expected household demand to decide when a home battery should charge and when it should supply the home. In a pilot, housing associations would get a view of how this performs across their homes.
- Reads. Electricity prices, time of day and expected demand.
- Decides. When to store electricity and when to use it.
- Manages. Batteries across participating homes.
- Measures. Costs, battery performance and resident feedback during the pilot.
Benefits
The pilot goals.
Kettle Energy aims to help housing associations offer warmer, more affordable homes. The first pilots will test whether the service can lower energy costs and give housing teams useful data on their stock, as well as gather feedback from residents.
01
Help residents manage household energy costs
Give residents clear, everyday information about their energy use so they can spot waste, change habits and keep more control over household costs.
02
Support residents in fuel poverty earlier
Spot unusual or inefficient energy use so landlords can offer support sooner to residents struggling to heat and power their homes affordably.
03
Give housing teams useful data on their stock
Use real energy data from participating homes to inform investment decisions, strengthen funding cases and protect the long-term value of housing stock.
04
Support EPC and decarbonisation planning
Measure energy use and carbon across housing stock to support EPC improvement plans, sustainability targets and reporting to stakeholders.
05
Build resident confidence and engagement
Turn energy data into simple, useful guidance that helps residents understand their homes, take part in energy-saving efforts and see the value of improvements.

Why Is Renewable Electricity Still Being Wasted?
On windy nights, Britain can produce more clean electricity than the network can deliver to the places using it. Understanding why that surplus goes unused is the starting point for using it better.
