Retele Electrice Romania has announced the launch of a tender for a major energy infrastructure modernization project in Calarasi County, with an estimated budget of 15.6 million euros. The initiative focuses on improving energy distribution efficiency and reliability in the communes of Stefan cel Mare, Perisoru and Borcea.
The project includes the reconfiguration, modernization, and capacity expansion of the Perisoru medium-voltage overhead transmission line. Notable upgrades include replacing conductors, undergrounding approximately 35 kilometers of the line, and modernizing around 50 kilometers of low-voltage networks. The project also involves the installation of fiber optic cables to enable a high-performance SCADA remote control system.
Additionally, 11 substations will be upgraded. Nine of these will be relocated from poles into new concrete enclosures, while two masonry substations will be moved to public areas. The initiative also includes the installation of six new transformer substations and three new connection points, all within concrete structures. These improvements will introduce advanced equipment, remote monitoring capabilities, and increased distribution capacity, ensuring a more reliable power supply.
As part of the effort, more than 2,500 consumer connections in Stefan cel Mare and Perisoru will be modernized. This includes relocating metering groups from property boundaries and reconstructing subscriber columns to improve overall efficiency.
The modernization aims to enhance energy security, reduce environmental impact by lowering CO2 emissions, and minimize distribution losses. The total cost of the project is estimated at 16.3 million euros (excluding VAT), with up to 11.4 million euros co-financed by the Modernization Fund.
Bidders interested in participating must submit their proposals by 18 March. The project is expected to take 25 months from the date of contract signing. Retele Electrice Romania operates an electricity distribution network of approximately 134,000 kilometers across three major regions—Muntenia Sud (including Bucharest), Banat, and Dobrogea—covering one-third of Romania’s energy market.
