For East Lothian businesses, a commercial battery is a tool for cutting costs in two ways: storing surplus solar generation for later use, and reducing peak demand charges by discharging during high-demand periods. If your business has high or spiky electricity use, battery storage can pay for itself faster than many expect.
Peak shaving for businesses
Many commercial electricity tariffs include demand or capacity charges based on your peak draw from the grid. A battery can detect when your demand is approaching a peak and discharge stored electricity to flatten that spike — known as peak shaving. Over a year, reducing peak demand can meaningfully lower your unit costs.
Storing surplus solar
If your business has commercial solar panels, a battery stores the surplus generation you do not use during the day — common on weekends or when production lines are idle — and makes it available when your business is running at full tilt.
Off-peak arbitrage
For businesses on time-of-use tariffs, a commercial battery can charge on cheap overnight electricity and discharge during expensive daytime periods. This works even without solar, turning cheap off-peak power into a hedge against peak rates.
Sizing a commercial battery
Commercial battery systems are sized to your demand profile — typically from tens of kWh up to several hundred kWh for larger premises. Our MCS-certified partners analyse your half-hourly consumption data before recommending capacity. Most commercial batteries are modular, so capacity can be expanded later if your needs grow.
Three-phase and grid connection
Commercial battery installs in East Lothian typically connect to a three-phase supply. Our partners handle grid notification and G99 application where required, so your install is compliant and your export limit is properly configured.
