Summary
Machine-generated summarySlovenske elektrarne (SE) is conducting a preliminary market consultation for control software to hybridize a motor generator with a battery energy storage system (BESS). SE operates one battery storage site at Dobsina, is building two more at Novaky and considers further investments. The software should maximise synergies between existing spinning resources and new battery storage, focusing on trading on the interday market and provision of ancillary services. Charging strategies must enable certification for ancillary services under the Slovak transmission system operator SEPS and optimise battery cycling. Regarding the BESS considered at the Cierny Vah site, SE wishes to assess whether market solutions can achieve significantly larger technical and economic benefits than the current BESS management principle at Dobsina.
