The integration of nearly 10 GWh of storage will play a crucial role in balancing the grid, stabilizing renewable output, and ensuring that clean energy is both reliable and accessible. Sigenergy, in partnership with the leading Bulgarian energy company Trakia MT, has successfully completed a 20 MWh utility-scale co-located project in Malko Tarnovo, located in southern Bulgaria. Driven by the dual goals of climate neutrality and energy autonomy, Europe is rapidly shifting toward a. Stacks are primarily used for home systems but Sigenergy has installed a 10 MW/20 MWh project at a solar site in Malko Tarnovo. Historically, Bulgaria has also been a major producer and exporter of electricity for the surrounding region with a total of 10 inte connectors spread across Romania, Serbia, North Macedonia, Greece, and Turkey. The. e System) are the future of electricity storage. Today,we will explore the key tec nologies and components th eferral and/or large-scale.

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. The applic
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.
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.
Can battery-based energy storage improve peaking capacity in Bulgaria?
storage can also ofer greater flexibility and eficiency in managing the grid. 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
