Romanian engineering and technology group Simtel has brought online a 52 MW solar power plant in Giurgiu, now the largest photovoltaic facility in the country built entirely on rehabilitated industrial land. Constructed on the grounds of a former ash disposal site, the plant is expected to generate around 73 GWh of electricity per year. Completed in the last quarter of 2025, the project was fully developed by Simtel—from land acquisition and design to construction, automation, and commissioning.
Simtel CEO Mihai Tudor emphasized that the Giurgiu project demonstrates the potential of neglected industrial areas to be transformed into productive renewable-energy assets. He noted that the unstable terrain of the former ash pit required complex engineering approaches rarely used in standard greenfield solar developments.
Simtel acquired the 83-hectare site in October 2021. The area includes a 16-hectare lake formed within the old ash pit. The investment was financed through a mix of sources: a €12 million non-repayable grant from Romania’s National Recovery and Resilience Plan, a bridge loan from Banca Transilvania, and a €16 million investment loan. The plant consists of more than 85,000 solar modules and 170 smart inverters, feeding power into the national grid through six transformer stations and a newly built high-voltage substation.
Electricity from the facility will be supplied under a 10-year Power Purchase Agreement between Simtel and G-Energy Solutions, of which Simtel owns 62 %. Over the contract period, Simtel will deliver an expected 736 GWh to G-Energy’s clients.
Simtel’s development pipeline is also expanding. The company now owns nine solar projects in various stages of construction and permitting, totaling 153 MW and expected to produce over 200 GWh annually. Four projects—Plesoiu (phases 1 and 2), Iacobeni, Salonta, and Giurgiu—are already operational. Additional developments in Anina, Ianca, Mangalia, and Movilita are scheduled to be completed by the end of 2026.
Simtel is also moving forward with preparations for the Bughea solar project in Argeș County. With a planned capacity of 70 MW and commissioning targeted for the second quarter of 2027, it is set to become Simtel’s largest proprietary solar installation to date.
