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.
How it works
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.
