We connect energy storage, market optimisation and distributed computing to unlock more value from every site.
- Store energy when prices are low. Use or sell it when it is worth more.
- Give suitable EV batteries a second life as energy storage.
- Turn available power into computing services and useful heat.

Circular batteries
Circular Batteries
Retired from a car does not have to mean finished. We assess suitable EV batteries for a second life storing electricity.

Computing & heat recovery
Edge Compute
Use available power to run paid computing work, then recover useful server heat for hot water and building heating.
Explore computing & heatStart with what you have
One platform.
Three ways to create value.
You do not need to be an energy trader or a computing expert. Tell us what you have, and we’ll explore where it could fit.
“I have a site or energy assets.”
Explore battery arbitrage, lower electricity costs and eligible payments for supporting the electricity network.
Explore this service →“I have batteries to repurpose.”
We welcome battery suppliers, fleet operators and dismantlers interested in responsible second-life storage.
Explore this service →“I have power, space or a need for computing.”
Explore hosting GPU and CPU equipment, buying computing services, or putting recovered server heat to use.

Intelligent energy. Circular infrastructure. Productive computing. Each service strengthens the next, helping unlock more value from a suitable site.
Store at the right time.
Give suitable EV batteries a second life. Charge them when electricity is cheaper.
Make stored power work.
Reduce peak electricity use, explore arbitrage and provide eligible grid flexibility.
Compute. Recover heat.
Use available capacity for computing, then recover useful heat for water and buildings.
A useful starting point
What could your
home save?
A home bill-savings estimate for storing solar power or charging a battery at cheaper times. Grid income, computing revenue and heat recovery require a separate site assessment.

Store power when it costs less. Use it when you need it.
Your savings estimate will appear here.
Potential annual electricity savings
- Using more spare solar power
- Charging at cheaper times
- Extra grid-service income
- Eligibility check needed
Estimated bill savings before service and equipment costs. Subject to your home, tariff and eligibility.
What’s included in your estimate?
Starting figures: 2,700 kWh is a household reference point, not an estimate of a solar home’s grid purchases. The 26.32p daytime starting rate reflects Ofgem’s GB Direct Debit average for October–December 2026. The 9p off-peak figure is an illustrative smart-tariff rate; some specialist tariffs offer this level but have equipment and eligibility conditions. It is not a rate available to every household. Replace both rates with your own. With no off-peak discount, use the same figure in both fields.
References checked 17 October 2026: Ofgem unit rates and an example specialist off-peak tariff. EV charging and heat-pump benefits are not added to this battery calculation; they are included in your assessment request.
Service charges, equipment, installation, maintenance and battery wear are not priced or deducted. Results are not a quote or guarantee. Extra grid income requires a separate eligibility check.
We estimate the benefit of moving electricity to a cheaper time, allowing for energy lost when charging and discharging. The two scenarios use 150 and 300 battery cycles per year, 80% of rated battery capacity and 90% round-trip efficiency. These are modelling assumptions, not measured performance or confidence limits. Power limits, charging windows, seasonality and your actual usage can reduce the opportunity.
We limit energy shifted to 60% of the electricity you currently buy from the grid. For an existing solar-and-battery system, the selected solar reserve reduces the capacity available for cheaper grid charging. We do not count existing solar or battery savings again. If you already charge cheaply, or are unsure, we request a personalised review rather than claim those savings are new.
For solar homes considering a new battery, stored solar is limited by exported electricity, battery capacity and remaining grid demand. We deduct lost export income and charging losses. Any remaining capacity can then be used for cheaper grid charging, so the same capacity and household demand are not counted twice. The annual model cannot determine your actual daily charging schedule.
The result compares the entered setup with your current grid purchases at the usual price entered. It assumes eligible equipment and an available cheaper tariff. Standing charges and other tariff changes are not included. Hardware and service costs need to be included in your personalised assessment before you decide.

Plain-English answers
A little more clarity.
Do I need solar panels, a battery and computers?
No. You can explore one service on its own. Start with the equipment or space you have and the outcome you want.
Can this work at my home?
Solar storage and smarter battery use may suit homes or businesses. Computing needs a separate assessment of the space, electrical supply, internet, cooling and costs.
How much could I save?
Use the savings calculator for an initial guide to battery savings. A personalised assessment needs your actual tariff, usage, equipment and all costs.
Try the savings calculatorWhat are second-life batteries?
They are suitable used batteries, often from electric vehicles, tested and repurposed to store power for buildings. Condition, safety, warranty and installation requirements still need to be checked.
What will it cost?
The cost depends on your property and the proposed system. We discuss equipment, installation, service charges and the commercial terms before any commitment.
