Grid operator dispute blocks full battery use at 76.5 MWh German hybrid plant

Eon Edis has withdrawn previously agreed import capacity from a newly commissioned 69 MW solar-plus-storage plant in northeastern Germany, according to pv magazine. The decision limits the site's 76.5 MWh battery to storing only generation produced on-site, blocking the grid-charging cycles that typically anchor merchant BESS revenue in the German zone.

The move sets up a direct operator-versus-DSO dispute over contracted connection rights. For asset owners and lenders elsewhere in Germany, the case raises questions about the enforceability of pre-agreed import allocations at the distribution grid level, particularly for hybrid plants where the battery is sized partly for arbitrage.

On the supply side, EVE Energy signed a five-year battery framework with Fluence covering 206 GWh in total. Committed deliveries stand at 16 GWh for 2027, with 190 GWh of reserved capacity allocated to subsequent years. The deal signals continued large-scale procurement confidence even as individual projects face grid-connection friction in European markets.
