The energy transition is entering a new phase. For years, the focus has been on how to produce more renewable energy. Today, one of the central questions is how to make energy systems flexible enough to use that energy reliably, safely and efficiently.
As the share of renewable energy grows, electricity grids need more than generation capacity. They need resilience. They need flexibility. And increasingly, they need large-scale battery energy storage systems capable of balancing supply and demand, reducing the risk of blackouts and supporting the integration of renewable energy into everyday power systems.
This is the challenge that EBRD (The European Bank for Reconstruction and Development) is helping to address through its financing to NGEN Energetske Rešitve, a Slovenia-based energy storage company.
As set out in EBRD’s announcement, EBRD has provided up to €70 million in financing to NGEN for the construction and operation of five large-scale battery energy storage systems across Slovenia, Latvia, Poland and Romania. The transaction also received coverage from Finance, Siol.net and The Slovenia Times, reflecting its relevance for the region’s business and energy sectors.
The systems will deliver a total of 302 MW of stored energy capacity and are expected to strengthen electricity grid stability in four EU member states. The projects in Slovenia and Latvia will be among the largest standalone utility-scale battery installations in their respective markets, where large-scale energy storage remains underdeveloped.
The battery storage systems will be supplied by Tesla and will operate under a merchant model, selling energy directly into the wholesale market. According to EBRD, increased availability of battery energy storage systems is critical for the development of more flexible and resilient power systems.
ODI Law advised EBRD on Slovenian law aspects of the transaction. Legal counsel on the Slovenian part was provided by ODI Law Partner Primož Mikolič, Senior Associates Eva Hafnar and Tilen Kosec.
“We are pleased to have advised EBRD in a transaction that reflects both the ambition and the practical complexity of the energy transition. Projects of this scale require not only technology and capital, but also robust legal structuring that can support long-term implementation across markets,” said Primož Mikolič, Partner at ODI Law.
The transaction also includes EBRD support for strengthening NGEN’s cybersecurity resilience through targeted technical cooperation and advanced risk mitigation solutions, further underlining the importance of operational reliability in modern energy infrastructure.
For ODI Law, the mandate reflects the firm’s continued work with clients developing the infrastructure, technologies and financing structures behind the region’s sustainable energy future.
We are grateful to EBRD for their trust and pleased to have contributed to a project that supports more resilient, flexible and sustainable energy systems across Europe.
