Projects & Applications
Big things ahead for Romanian BESS investments Aurora Energy Research foresees double digit internal rates of return for standalone battery energy storage (BESS) projects entering the market as early as 2026, while co-located assets could prove even more promising – especially post 2028 where rising saturation in the balancing markets is observed. Romania's energy minister said the country is targeting 3 GWh over the next few years.
