At South Mimms Motorway Services on the outskirts of London, Open Energi have installed a 250kW/500kWh Powerpack alongside one of Tesla’s busiest UK charging locations. The Supercharger site can charge up to 12 cars at one time, and since popular charging periods often coincide with peak periods of grid demand when electricity prices are at their highest – flexible solutions are needed to ease the strain on the local network and control electricity costs. Integrating a Powerpack at the location has increased on-site energy capacity (from800kVA to 1050kVA) This has kept costs down by avoiding peak tariff consumption and capping the maximum grid power. Throughout the remainder of the day, the Powerpack system charges from and discharges to the grid, earning revenue.
