SolarPro is providing turnkey engineering, procurement and construction (EPC) services on the project for owner Renalfa IPP, a developer-operator, and construction will start next year. The announcement claimed it is the largest BESS ‘in implementation’ in Southeast Europe.

It comes shortly after Bulgaria launched a public consultation into a grant scheme to support the deployment of up to 150MW of utility-scale energy storage in the country, with ultimate plans to facilitate the deployment of 350MW of the technology.

Hithium is one of the few companies producing lithium-ion batteries at scale with a focus on energy storage systems (ESS) rather than electric vehicles (EVs).

For this project Hithium will provide 16 containers each with a capacity of 3.44MWh capacity, comprised of the company’s 280Ah cells. The company did launch a 5MWh container product using its newer 314 Ah cells at the RE+ expo and conference in Las Vegas in September, but that does not appear to be being used for this project.

The tie-up with SolarPro in Bulgaria comes four months after Hithium launched in Europe, opening an office in Munich amidst a targeted ramp-up to 135GWh of production capacity globally by 2025. A month later it raised US$620 million in private capital.

More recently, it announced a 1GWh memorandum of understanding (MOU) with US developer Perfect Power to provide BESS there.
