A different kind of volatility: Battery revenues remain strong in May 2026 April was defined by solar-driven oversupply and recurring negative prices. May told a different story. Wind generation dropped sharply, wholesale prices climbed, and ancillary services gained importance as the system searched for flexibility. Yet battery revenues barely moved. Lennard Wilkening, CEO of suena energy, explains why this is another reminder that successful battery trading depends less on any single market regime than on the ability to adapt across them.
