Will Bulgaria reach 10 GWh of battery storage capacity?

The new system also signals the beginning of Bulgaria's national plan to reach 10 GWh of battery storage capacity within the next year. A recent capacity tender has already allocated nearly 9,713 MWh to upcoming projects, further reinforcing the country's ambitions in energy storage.

How big is Bulgaria's energy storage capacity?

A recent capacity tender has already allocated nearly 9,713 MWh to upcoming projects, further reinforcing the country's ambitions in energy storage. Before the commissioning of the Lovech facility, Bulgaria's largest BESS was a 25 MW / 55 MWh system developed by Renalfa IPP in 2024.

Why is Bulgaria building a new power plant?

Energy Minister Zhecho Stankov hailed the installation as a milestone for Bulgaria's energy independence and regional leadership. “This facility will help maintain the most stable energy system in Southeast Europe,” he said. “We are the pillar of the Balkans in balancing electricity systems.”

What is a battery energy storage system (BESS)?

Sigenergy has deployed a 10 MW/20 MWh battery energy storage system (BESS) at a solar site in Malko Tarnovo, Bulgaria, using 240 kWh battery stacks typically found in residential systems. From ESS News Stationary BESS are typically categorized by size, beginning with stack systems, followed by cabinets, and ending with containerized units.
