A large solar power plant in southern Romania has taken its final regulatory step toward commissioning after receiving a commercial operating license from the national energy regulator. The 135 MW project, located in the Oltenia region, is backed by a shareholder structure led by Chinese state-owned energy group China Huadian.
With this license in place, the project has completed the entire permitting process required for newly built generation facilities and can now register on electricity trading platforms and begin selling electricity on the market.
The license applies to the Studina solar power plant in Olt county, which has a total installed capacity of 135 MW. The project is owned by Grup Blauer Bucuresti, a Romanian company whose shareholding reflects a mix of international renewable energy investors. Corporate records show that China Huadian Hong Kong Company Limited controls 45 % of Grup Blauer Bucuresti, while the remaining shares are split equally between Studina Renewables and CWP Europe, each holding 25.5 %. Through its Hong Kong subsidiary, China Huadian has been pursuing overseas investments as part of its broader international expansion strategy.
China Huadian ranks among China’s five largest electricity producers and operates a huge generation portfolio of around 178 GW, with annual electricity output estimated at approximately 640 TWh. While the group is state-controlled, its Hong Kong arm is used to access and develop energy projects outside mainland China.
The Romanian project company was originally acquired three years ago by CWP Europe, part of the global renewable developer CWP Global, from a group of local investors. At the time of that transaction, the company already held a network connection agreement with Romania’s transmission system operator Transelectrica, and the solar plant was expected to enter operation in 2025. China Huadian later joined the shareholder structure, taking a significant minority stake.
The approval comes amid a rapid acceleration of solar capacity additions in Romania. Installed solar capacity, including utility-scale projects and prosumers, surpassed 7 GW in 2025. Industry forecasts suggest that an additional 2.5 GW of solar capacity could be connected to the network this year, reinforcing Romania’s position as one of the fastest-growing solar markets in the region.
