Which service is right for you?

A battery is more than just storage. It’s flexible power that holds value in the energy market. When the grid is short on power, your battery is worth money. When there’s a surplus, you can buy power at a low price. The difference between taking smart action and doing nothing can amount to thousands of euros a year.

Flex Trading turns that value into reality. Covolt bundles your battery with other assets into a Virtual Power Plant and trades the power on multiple markets simultaneously. Our algorithms determine the optimal strategy every 15 minutes: charging, discharging, or reserving power for balancing services.

Covolt offers four versions of Flex Trading, each with its own focus and revenue model. From trading on predictable day-ahead prices to real-time trading on the imbalance market—or a fixed income through a tolling arrangement.
