Romania’s biggest battery system put into operation

Nova Power & Gas has commissioned the largest battery energy storage system in Romania, doubling the country’s total capacity. The installation in Florești, Cluj County, has an operating power of 200 MW and a capacity of 400 MWh.

Before the new facility was commissioned, Romania’s overall battery energy storage capacity was 398.8 MWh, according to data from the country’s transmission system operator, Transelectrica. Nova Power & Gas earlier said its own capacity was 240 MWh.

The company was already operating 240 MWh in batteries

The new battery energy storage system (BESS) became operational after Mayor of Florești Bogdan Pivariu signed a certificate of occupancy, Profit.ro reported.

In addition, Nova Power & Gas is building a 150 MW gas-fired power plant in Câmpia Turzii, with the first phase set to come online by December 2026.

Nova Power & Gas is developing further battery systems totaling 1,200 MWh

By 2028, the company plans to install one more gas power plant, of 200 MW, and energy storage systems of another 600 MW / 1,200 MWh overall.

“Through these investments, we aim to maintain and strengthen our leadership in energy storage, while making substantial investments in gas-fired electricity generation to support balance and flexibility in the national energy system,” Septimiu Costea, CTO of Nova Power & Gas, stated in July.

Nova Power & Gas, part of Romania-based E-Infra Group, is active across the Southeast Europe region, with subsidiaries in Bulgaria, Serbia, Hungary, and Moldova.

The company is also a major power and natural gas supplier, with over 4.6 TWh of electricity and gas delivered in 2024 and a turnover of almost RON 3 billion (EUR 589.4 million), according to Profit.ro.
