WALDEVAR Energy and GEN-I Sonce expand partnership with a 220 MWh battery energy storage project in Romania
The next chapter of Europe’s energy transition will be defined by how effectively energy can be stored, managed and delivered to the grid. As battery energy storage moves from a supporting technology to critical energy infrastructure, WALDEVAR Energy and GEN-I Sonce are expanding their partnership with the signing of an EPC contract for a 55 MW / 220 MWh Battery Energy Storage System (BESS) in Gheorgheni, Romania.
The project represents another important milestone in the collaboration between the two companies, following the agreement signed earlier this year for the Gheorgheni 110 kV, 63 MVA Substation. Together, the two projects address two increasingly important elements of Romania’s evolving power system: the infrastructure needed to connect reliable and fast response power generation to the national grid and the storage capacity needed to balance the grid.
Under the agreement, WALDEVAR Energy will deliver 50MW/220MWh full EPC scope by Q3 2027 for the battery energy storage system, covering engineering, procurement, construction, installation, testing and commissioning.
Across Europe, battery energy storage is rapidly becoming a strategic investment. BESS stores electricity when it is available and releases it when it is needed, supporting the grid to manage fluctuations between supply and demand, respond to changing market conditions and provide greater flexibility to the grid. As electricity systems become more dynamic, large-scale storage is increasingly important for maintaining system stability.
“For years, the industry’s priority was adding renewable generation. Today, the challenge is making energy available when the system actually needs it. Battery storage is becoming one of the most strategic assets in the energy sector because it provides the flexibility to store energy and discharge it when demand or system conditions require it. Gheorgheni is a strong example of how large-scale BESS can contribute to a more flexible and resilient energy system. This project also marks another important step in our growing partnership with GEN-I Sonce and strengthens WALDEVAR’s capabilities in delivering complex utility-scale BESS projects across Europe.”, said Cristian Dragomir, CEO of WALDEVAR Energy.
The new agreement builds on the successful cooperation established between the two companies and reflects their shared commitment to accelerating the deployment of modern energy infrastructure across the region.
“This is the largest and most important project for the GEN-I Group and our first EPC project with WALDEVAR Energy in Romania. It is also the first step in a scalable model for how we develop and deliver energy storage projects. We believe the experience gained here will shape the projects that follow, and we are grateful for the trust and support of the local community and authorities in Gheorgheni.”, Gregor Hudohmet, CEO of GEN-I Sonce added.
“Today marks the beginning of an important project for Gheorgheni. A battery energy storage project developed by GEN-I Sonce and executed by WALDEVAR Energy will build the infrastructure needed to generate power to the national grid. Years from now, we will be proud of what we built here together.” said Len Emil Balázs, Vice Mayor of Gheorgheni.
