Technical FAQs 4

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.

Why is energy storage important in Bulgaria?

In 2023, the Bulgarian Parliament introduced specific legislative amendments regulating the electricity storage. The rationale behind the amendments is to provide balance and flexibility to the power system. Energy storage is a crucial step for low-carbon economy since it enhances the security of supply and the development of renewables capacity.

How many solar projects are there in Bulgaria?

Currently, Bulgaria operates over 800 megawatts of wind projects Bulgaria has an annual average of 2,100 hours of solar irradiation. As of 2023 over 1,700 megawatts project are operational in Bulgaria and it is growing substantially. Geothermal energy is gaining attention, with legislative proposals to harness Bulgaria's geothermal potential.

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.
