Peak shaving
Discharge during your highest-demand periods so your site draws less from the grid when it is most expensive. On a DUoS red-band tariff this is often the single largest saving.
For Business
Storage that earns its place on the balance sheet
A commercial battery is only worth installing when your load profile says so. We start with your half-hourly data and tell you honestly whether the numbers work.
Value streams
Six ways a commercial battery pays
Most viable projects stack two or three of these. A project resting on only one is usually marginal.
Capacity charge management
Reducing your maximum demand can lower authorised supply capacity charges — a fixed cost many sites never revisit after their original connection.
Solar self-consumption
Weekend and shutdown generation that would otherwise be exported at a low rate can be stored and used on the next working day.
Resilience and backup
For sites where an outage means spoiled stock, halted production or clinical risk, storage can hold critical circuits while a wider strategy takes over.
Avoiding a grid upgrade
Where new load — EV charging in particular — would exceed your connection, storage can sometimes buffer demand and defer an expensive DNO reinforcement.
Flexibility services
Some assets can participate in grid flexibility markets for additional revenue. Eligibility and returns vary and must be verified, never assumed.
Sizing
Power and capacity are different things
A commercial battery is specified in two dimensions: how hard it can push (kW) and how long it can push for (kWh). Peak shaving demands power; overnight load shifting demands capacity. Getting this wrong is the most common reason a commercial system underperforms its business case.
- Half-hourly import data across at least twelve months
- Your tariff structure, including DUoS bands and capacity charges
- Peak demand events — how high, how often, how long
- Existing or planned solar generation profile
- Planned new load such as EV charging or electrified heat
- Which circuits, if any, must stay live during an outage
Delivery
What installation involves
- Location assessment — plant room, external compound or container
- Fire strategy, ventilation and separation distances
- Structural and civils work for the mounting position
- Switchgear modification and protection coordination
- G99 application to the network operator where required
- Commissioning, control strategy configuration and handover training
- Ongoing monitoring and a defined maintenance regime
When we'll tell you not to bother
If your site runs a flat daytime load on a simple tariff with no capacity constraint and no resilience requirement, a battery may add cost without adding much value. We would rather lose the order than install an asset that does not perform. In those cases we will usually recommend maximising the solar array first and revisiting storage when your tariff or load changes.
