Bulgaria: Energy Storage as a Catalyst for a Changing Power
Fortunately, Bulgaria sits in the privileged position where it can profit from the experiences of other energy systems with high renewable shares. Here, battery-based energy storage is
ablish a reliable energy system with greater share of intermittent generation. In the context of Bulgaria's energy landscape, energy storage solutions present a diverse array of benefits to various stakeholders stemming fro its unique ability to time-shift energy and rapidly respond when called upon.

Furthermore, and although hydropower storage already makes up a significant source of peaking capacity in Bulgaria, battery-based energy storage can address peaking needs during times of droughts, meet requirements for more distributed peaking po
The Renalfa IPP project in Razlog has been claimed as the biggest project of its type in Bulgaria. It is also larger than the biggest project to come online so far in neighbouring Romania, a 6MW/24MWh BESS in that country's Constanta County, co-located with solar PV and wind generation plants.
