Charging Ahead: Hungary's Newly Introduced Rules Fuel Co-located BESS Expansion

The expansion of renewable energy sources, particularly photovoltaic (PV) systems, has been a cornerstone of Hungary's strategy to diversify its energy portfolio and achieve sustainability objectives. However, the inherent variability of solar power generation presents challenges for maintaining grid stability and ensuring a reliable electricity supply. To address these challenges, the development of battery energy storage systems (BESS) co-located with solar power plants (i.e. cable pooling) has become increasingly important. Until now, however, the co-located BESS systems have been under-regulated and the numerous divergent and grey-zone practices have created uncertainty in the market, hindering the development of such systems. The changes introduced last week finally clarify and establish key steps for such developments.
