Energy Investment and CORNEX Partner To Develop 1 GWh Battery Storage Project In Romania

Energy Investment LLC and CORNEX New Energy have entered into a strategic cooperation agreement to develop a 1 GWh battery energy storage system (BESS) project in Romania, supporting the country’s efforts to strengthen energy storage infrastructure and integrate renewable energy into its electricity network.

The agreement follows an announcement made in June 2026 during The smarter E Europe exhibition, held in Munich from June 23 to 25. CORNEX highlighted the partnership in its official communication regarding its participation in the event, referring to a 1 GWh agreement with Energy Investment for a project in Romania.

Under the arrangement, Energy Investment LLC will be responsible for the complete development and execution of the project, while CORNEX New Energy will supply the battery energy storage technology. The cooperation agreement represents a development partnership and does not indicate that the proposed storage capacity is already operational.

According to information published by Energy Investment on LinkedIn on June 26, 2026, the company will oversee the project’s development and implementation. Romanian publication Profit.ro also reported on June 29 that CORNEX would provide the storage technology.

Marius Ion, Founder and CEO of Energy Investment LLC, stated that energy storage would play an important role in Romania’s energy transition by enabling renewable electricity to be used when required by the power system. He highlighted that the partnership with CORNEX would provide access to the technology needed to advance the proposed 1 GWh project.

The company indicated that the first projects could reach commissioning in 2027. However, the timeline remains dependent on several development stages, including permitting, grid connection, regulatory authorizations, financing and equipment procurement.

The proposed project is expected to support Romania’s renewable energy integration by providing storage capabilities to improve electricity system flexibility. The partnership also reflects growing cooperation between international technology suppliers and project developers as European markets expand their battery storage infrastructure.
