Battery storage

Time-shift, peak avoidance, resilience, flex revenue — from one asset.

A battery is one piece of kit doing four jobs. We design and fund commercial battery storage for UK businesses — sized to your load, your tariff, your solar and your resilience requirements.

4 use cases
Solar shift, peak avoid, DSR, resilience
5-10 yrs
Typical payback range
4 funding routes
CapEx, lease, EaaS, share

The use cases — most batteries pay back by stacking them

Time-shift your solar

Store daytime solar generation and discharge into evening peaks. Self-consumption rises; export at low rates falls.

Peak-tariff avoidance

For half-hourly settled sites, discharging through your daily peak periods can materially cut your distribution and capacity costs.

Resilience and back-up

Critical loads stay live through grid faults. For hospitals, cold chain and data-room operations, that's a value beyond the energy bill.

Flex-market revenue

Batteries can earn through Demand-Side Response, Capacity Market and balancing services — we model the realistic stack, not just the headline.

Sized to the load

Battery sizing is a function of your half-hourly profile, your solar (if any) and your tariff structure. We don't size to a brochure spec.

Funded the way you want

CapEx, lease, EaaS or shared-savings. We model each route against your balance sheet before recommending.

Flex Portfolio

Move from a single price-fix to a portfolio you actively manage.

Our trade desk currently manages over 150 GWh in flex contracts on behalf of UK businesses, and beat supplier projections by 20% in the last 12 months. You stay in control. We do the trading.
