€70M Powers Giant Battery Network Across Eastern Europe

Five giant batteries are about to transform how Eastern Europe stores and uses clean energy, thanks to a €70 million investment that just changed the game.

Slovenia-based NGEN Energetske Rešitve landed the loan from the European Bank for Reconstruction and Development to build battery energy storage systems in Latvia, Poland, Romania, and Slovenia. Together, these five facilities will deliver 302 megawatts of storage capacity, enough to balance the grid and make renewable energy far more dependable.

The batteries in Latvia and Slovenia will be among the largest standalone storage systems ever built in their countries. Eastern Europe has lagged behind Western nations in energy storage technology, making this project a major leap forward for the region.

Tesla will supply all five systems, which will operate independently in wholesale electricity markets. That means they'll buy power when it's cheap and plentiful (like sunny afternoons with lots of solar) and sell it back when demand spikes, helping stabilize prices and reduce waste.

The European Union backed the deal with a safety guarantee through its InvestEU Fund, reducing the financial risk and making the project possible. The EU is also providing technical support to help NGEN strengthen its cybersecurity, protecting these critical energy systems from digital threats.

The Ripple Effect

This investment signals that Eastern Europe is finally catching up in the global energy storage race. Grid-scale battery capacity worldwide has grown twelve times larger in just four years, and merchant storage systems like these are among the fastest-growing segments.

The EBRD has been actively funding similar projects across the region, recently backing a 250-megawatt battery system in Hungary and taking its first stake in a Croatian storage facility. Each new project makes the next one easier to finance and faster to build.

These batteries will help countries use more wind and solar power by storing excess energy for cloudy, windless days. That means less reliance on fossil fuels and more stable electricity prices for families and businesses across four nations.

NGEN doesn't just build batteries; it operates them, engineers them, and supplies storage systems for homes and businesses too. This comprehensive approach means the company can share lessons learned across different scales and markets, speeding up progress throughout the sector.

One loan is powering progress across an entire region, proving that smart infrastructure investments can multiply their impact far beyond borders.
