Romania's Rapid BESS Expansion and Tesla Megapack Deployments
Surpassing 1 GW of Installed Capacity
Romania is rapidly establishing itself as a leading battery energy storage market in Southeastern Europe, driven by aggressive regulatory approvals and significant international investments. According to data from Transelectrica valid as of September 1, 2026, Romania's total installed battery energy storage capacity has reached 1,094 MW in power and 2,310 MWh in energy capacity. The momentum is further evidenced by the Romanian Energy Regulatory Authority (ANRE), which recently approved over 1,015.7 MW of new energy capacity in a single meeting, with storage projects dominating the approvals at 669 MW.
Tesla Megapack and EBRD Financing
A major catalyst for this growth is the deployment of Tesla Megapack technology. ANRE recently granted an establishment permit to ENERGY STORAGE SOLUTIONS S.R.L., a local subsidiary of the Slovenian company NGEN, for a 115.5 MW / 230 MWh BESS in Tudor Vladimirescu, Brăila. This project is part of a broader expansion, as the European Bank for Reconstruction and Development (EBRD) provided a €70 million loan to NGEN to build and operate five BESS systems totaling 302 MW across four EU member states.
Additionally, PPC Renewables Romania is developing a 60.12 MWh BESS at the Salbatica 1 wind farm in Tulcea County, co-financed by the European Modernization Fund to optimize renewable generation.
These developments highlight Romania's strategic role in the EU's broader energy storage landscape, leveraging European funding and advanced battery technology to secure its grid and accelerate the green transition.
