Three years ago, SCU deployed the country’s first 40ft containerized energy storage system at a solar farm in Bulgaria, setting a precedent for large-scale industrial and commercial energy storage.Why is energy storage growing in Bulgaria?Energy storage in Bulgaria is expanding rapidly as the government awards nearly 10 GWh of capacity to 82 projects, boosting renewable energy reliability and grid stability.
How will the selected storage systems be distributed in Bulgaria?The selected storage systems will be geographically distributed across Bulgaria and connected either to the national transmission grid or local distribution networks. All awarded projects must be operational by March 2026.
How big is Bulgaria's solar PV capacity in 2024?At the close of 2024, Bulgaria’s solar PV capacity had already reached 3.91 GW—an annual increase of over 1 GW. These developments come on the heels of Bulgaria’s first renewable energy auction held in late 2024, where more than 3 GW of generation and 1.176 GW of storage capacity were secured.
What does Bulgaria's surge in storage capacity mean for Europe?As Europe races toward climate neutrality, Bulgaria’s surge in storage capacity signals a shift not only in national priorities but also in regional energy dynamics.
Is Bulgaria moving towards a greener energy future?Bulgaria is taking bold steps toward a greener energy future, having recently wrapped up its most ambitious energy storage tender to date.
How much energy can a Bess storage container hold?A large container can store up to 5 MWh of energy. Cabinets typically hold several hundred kilowatt-hours, while stacks are mainly used by homes and small businesses. Although smaller BESS types can be combined, they have rarely been used to match the capacity of larger systems – until now. To continue reading, please visit our ESS News websi
