Utility-Scale Storage Expands in Romania

Romania is rapidly emerging as a premier destination for utility-scale battery energy storage systems (BESS) in Central and Eastern Europe. Driven by ambitious national renewable targets, the country is witnessing a surge in major storage deployments designed to manage solar variability and maintain grid stability.

LONGi and Enexus in Titu

In a significant move, Chinese solar giant LONGi and Romanian developer Enexus have signed an agreement for a 50 MWh liquid-cooled BESS deployment in Titu, Dâmbovița County. The deployment comprises two projects: Titu 1, featuring 20 MWp of PV and 15 MW of BESS, which is fully completed and awaiting grid connection; and Titu 3, with 35 MW of PV and 35 MW of BESS currently under development. The system utilizes 10 units of LONGi’s liquid-cooled utility-scale solution paired with integrated medium-voltage skid systems, designed to extend operating life through uniform cell-temperature cooling.

Romania's updated National Energy and Climate Plan targets 5.8 GW of ground-mounted solar by 2030, creating a massive need for utility-scale storage.

Renovatio Solar's 918 MWh Mega-Project

Adding to this momentum, Renovatio Solar has partnered with CATL to build the Borzești Energy Storage project. At 918 MWh, it will be the largest BESS project of its kind in Romania. Developed by Borzești Energy Storage SRL—a joint venture between RNV Infrastructure and Greenvolt Power—the project will feature full EPC services by Renovatio Solar over a 12-month execution period. The system will capture surplus midday solar electricity, discharging it during evening peaks and providing rapid frequency response to reduce reliance on electricity imports.

Aligning with National Climate Goals

These projects align perfectly with Romania's updated National Energy and Climate Plan (NECP), which targets approximately 5.8 GW of ground-mounted solar and at least 2.5 GW of rooftop solar by 2030. As solar capacity expands, utility-scale storage is becoming the critical enabler for grid reliability and renewable integration.
