Circle K tackles power supply challenges with new “giant power bank”

The retailer is installing a combination of solar panels and a large-scale battery storage system in Sweden.

Circle K is addressing power supply constraints at its Flädie station by installing a combination of solar panels and a large-scale battery storage system. This development aims to resolve the challenges associated with lengthy lead times and insufficient grid capacity, paving the way for the deployment of more ultra-fast chargers for both heavy and light vehicles.

The new system, described as a “giant power bank,” will provide energy security and support the station's operations by utilizing 800 kW/1600 kWh of battery capacity. When integrated with solar energy and the existing grid connection, the facility will have a total capacity of 1.4 MW. The implementation is expected to enhance the availability of power during peak demands, as well as stabilize the local grid by balancing energy supply between the station and its charging infrastructure.

“It’s exciting to test new technology and implement it on a larger scale, supporting the operations of an entire station. This project demonstrates that solutions can be found if the will is there, and we will continue to push forward to ensure the necessary transition, despite the current lack of policy support,” said Lennart Olsson, Head of Heavy-Duty Charging at Circle K.

Alongside the energy storage and solar system, Circle K has now opened charging facilities for heavy vehicles at the Flädie station, in addition to four new charging points for passenger cars.
