Store for later.
Use a compatible battery to hold solar generation or lower-cost electricity for another time.
INTELLIGENT ENERGY
Use electricity
at better times.
Solar, batteries and flexible electricity use can work together to lower costs. We help you assess when to store, use or export power around your site’s priorities.
- Solar generation
- Battery storage
- Site use or eligible export
WHO IT’S FOR
Homes, commercial sites and energy asset owners.
START WITH
Your tariff, electricity use and equipment.
THE NEXT STEP
A clear assessment of the options and commercial terms.
WHAT CHANGES
Your energy.
A more considered plan.
The value comes from making the right decision at the right time, while respecting the limits of the equipment.
Reduce expensive purchases.
Plan discharge around your demand, tariff and chosen battery reserve.
Assess export and flexibility.
Compare eligible payments with the cost of energy, battery wear and service fees. Market access depends on the agreement.
- Lower-cost electricity
- Store for later
- Displace higher-cost use
FROM A DECISION TO A RESULT
Timing matters.
The whole cost matters too.
A lower purchase price is only part of the calculation. Battery losses, wear, power limits and export terms all affect the outcome.
Our calculator lets you explore a reference scenario. A site proposal uses your actual information and sets out equipment, installation and ongoing costs.

Fleet charging belongs
in the energy plan.
A depot’s vehicles, other electrical loads and battery storage all share the same connection. Planning them together can reveal where time and capacity are available.
Explore fleet chargingBEFORE YOU DECIDE
Understand the fit.
Do I need solar panels?
No. Some battery use cases depend on tariff timing rather than solar. Eligibility for particular tariffs and programmes still needs checking.
Can a battery earn from the grid?
Some eligible assets can participate through suitable market arrangements. Payments, metering, availability commitments and fees must be confirmed for the service.
Who controls my equipment?
The proposal should state the permitted controls, your operating priorities, monitoring and what happens if communications fail.
THE PRACTICAL DETAILS
How an energy decision is made
Use generation on site first where it makes sense
Compare how much solar generation matches your electricity demand hour by hour. Direct use avoids buying that electricity at the import rate. Surplus can be stored or exported, depending on the value available in each route and your export arrangements.
Check Ofgem’s export guidanceBuy, store and use at better times
Battery arbitrage is the difference between what energy costs to put into a battery and what it is worth when discharged. For example, at 90% round-trip efficiency, putting in 10 kWh leaves about 9 kWh to use. The price difference needs to cover the lost energy, battery wear and service costs.
Try a reference estimateRespect limits and keep a reserve
The plan needs both kWh, the energy the battery can hold, and kW, how quickly it can charge or discharge. Add usable capacity, reserve settings, the inverter limit, the site’s import and export limits and any warranty conditions. These determine which opportunities can actually be delivered.
Work with your own tariff and usageAssess market access separately
On-site savings, supplier export payments and contracted flexibility are different sources of value. Flexibility means changing when the site imports or exports in response to a request. Check the route to market, metering, availability and settlement terms before assuming payments. Check that two proposed services can use the same equipment without conflicting commitments.
