Technical FAQs 4

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.

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.

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.
