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.

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.

“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.

“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.

With more than 3.5 GW of renewable energy infrastructure delivered, under construction or contracted across Europe, over 2,000 in-house specialists and a fleet of more than 400 specialized machines, WALDEVAR Energy continues to expand its role as one of Europe’s leading EPC contractors for renewable energy infrastructure.
