Where Commercial Storage Fits
Manufacturing
Demand peaks and demand-charge exposure can be reviewed with measured load data.
Logistics & Haulage
Charging fleets at the existing grid connection where capacity allows.
Retail & Property
PV self-consumption can be examined per site, depending on load and PV profile.
Utilities
Grid-service participation depends on metering, market access and operating concept.
Charge Point Operators
Add charging power within an existing connection budget where the load profile allows.
Economics: What Drives the Business Case?
Load profile
as a basis
kW / kWh
sized separately
Tariff sheet
checked per project
A defensible business case needs measured load data, the grid operator tariff sheet and the planned operating strategy.
