Based on cycling requirements, three applications are most suitable for second-life EV batteries: providing reserve energy capacity to maintain a utility’s power reliability at lower cost by displacing more expensive and less efficient assets (for instance, old combined-cycle gas turbines), deferring transmission and distribution investments, and taking advantage of power-arbitrage opportunities by storing renewable power for use during periods of scarcity, thus providing greater grid flexibility and firming to the grid.

When Hamburger Hochbahn AG commissioned suena energy to market a stationary battery storage system at the Alsterdorf depot, the goal was to maximize revenues in the electricity and balancing power markets and to examine how battery storage could be used profitably at other sites. suena energy focused on an innovative approach: a combined multi-market strategy alternating semi-annually between front-of-the-meter (FtM) and behind-the-meter (BtM) operation, in full compliance with regulatory requirements.
