Story

The Sibiu BESS project is a utility-scale, stand-alone energy storage solution designed to provide critical flexibility and stability to the Romanian national grid. Currently at the Ready-to-Build (RTB) stage, the project leverages a high-capacity 50MW/100MWh configuration. Situated on a strategically prepared 1.5-hectare site, the facility is engineered to participate in ancillary services, arbitrage, and frequency regulation, capitalizing on the increasing demand for grid-balancing assets in the region.

The project has successfully cleared all primary development hurdles, offering a de-risked opportunity for immediate execution:

• Building Permits: Fully obtained for the main storage facility.

• Grid Infrastructure: A separate, dedicated building permit has been secured for the cable route, ensuring a streamlined connection process.

• Land Readiness: The entire 1.5-hectare perimeter is fully fenced. A heavy-duty concrete platform has been constructed and is officially registered with the Cadastre Office, significantly reducing civil engineering timelines.

• Grid Connection (ATR): The Technical Connection Permit (ATR) is “clean,” stipulating zero reinforcement costs for the network—a rare and high-value technical advantage.

• Grid Connection Agreement (CR): The Connection Contract (CR) is currently in the final process of being signed with the Transmission System Operator (TSO).

• Technology: Lithium-Ion Battery Energy Storage System (BESS)

• Installed Capacity: 50 MW

• Energy Capacity: 100 MWh (2-hour duration)
