Commercial battery storage · Via Threefold Energy

A new tariff lowers
your rate. Battery storage
lowers your bill.

If your business spends more than £10,000 a year on electricity, switching tariff is only half the story. A commercial battery system shifts your demand off peak-rate periods and cuts what you actually pay — for the life of the system.

What it does,
and who it's for.

A commercial battery charges when electricity is cheap — overnight, or when on-site solar is generating — and discharges during peak periods when grid power costs most. On a time-of-use tariff, peak rates can run two to three times the overnight rate. A well-sized battery captures that gap, every single day.

Who qualifies

Annual electricity spend of £10,000 or more
A commercial metered supply (not domestic)
Three-phase supply preferred, though not essential for every system
Roof, plant room, or car-park space for the battery

Do I need solar to benefit? No. A grid-tied battery can save money purely by charging at cheap overnight rates and discharging at peak, without any solar generation.
