ELCEN invests 600 million RON in Bucharest heating — NRG-IA

Modernizing CTE Grozăvești through high-efficiency cogeneration — what happened Electrocentrale București (ELCEN) is launching a major 600 million RON investment to construct a new high-efficiency cogeneration unit at the Grozăvești Power Plant (CTE Grozăvești). The state-owned company, controlled by the Ministry of Energy, is the largest producer of thermal and electrical energy in the capital. This project marks a major milestone in modernizing Bucharest's critical energy infrastructure. According to reports from News.ro and Profit.ro, the funding is fully secured through the Modernisation Fund. This financing line provides non-reimbursable European funds, reducing direct financial pressure on the state budget and local consumers. The public procurement procedure has already been uploaded to the Electronic Public Procurement System (SEAP) to begin the contractor selection process. The new unit will replace obsolete equipment and run on natural gas, featuring high operational flexibility. The project includes installing state-of-the-art gas turbines, heat recovery steam generators, and advanced digital control systems. This configuration allows for rapid production adjustments based on grid demand. Technological degradation of the district heating system and the need for decarbonization Bucharest's energy infrastructure currently operates at its limits due to equipment commissioned over half a century ago. CTE Grozăvești, one of the oldest power plants in the country, uses low-efficiency installations that cause massive thermal energy losses. The physical and moral wear of these assets has generated massive maintenance costs in recent years. In addition to efficiency issues, ELCEN faces strict environmental obligations imposed by the European Union. Purchasing carbon dioxide (CO2) emission certificates represents a significant financial burden for the company. Without a swift transition to high-efficiency cogeneration, operational costs would have continued to rise sharply, threatening the continuity of the public service. Implementing this project through the Modernisation Fund is part of a broader decarbonization strategy for the urban heating sector. The new technology will significantly reduce the capital's carbon footprint, aligning the district heating system with European industrial emission standards. Increasing energy efficiency and reducing grid losses in the capital Transitioning to high-efficiency cogeneration means simultaneously producing electricity and thermal energy using significantly less fossil fuel. For Bucharest consumers, this technical mechanism translates into increased stability in hot water and heating delivery. The modernized plant will deliver constant thermal energy, reducing pressure fluctuations in the transport network operated by Termoenergetica. The national energy grid will also benefit from a new baseload electricity production capacity located right in the country's main consumption hub. This geographical proximity reduces transmission losses in the high-voltage grid managed by Transelectrica. During winter peaks, the input from the new unit at CTE Grozăvești will secure local balancing for the electrical grid. From a financial perspective, the increased efficiency of the new plant will help curb gigacalorie production costs. Although final tariffs are regulated by ANRE and partially subsidized by the Bucharest Municipality, technical efficiency will lower the total volume of subsidies needed to cover grid losses. The tender launch in SEAP and the estimated project timeline The public procurement procedure launched by ELCEN sets strict qualification rules for interested industrial construction consortia. Bidding companies must demonstrate technical and financial capacity to manage a project of this complexity. The deadline for submitting bids will be a critical indicator of international contractors' interest in the Romanian market. One of the major risks identified in project implementation relates to tight execution deadlines imposed by Modernisation Fund regulations. Supply chain delays for heavy equipment, such as gas turbines, could pressure the construction schedule. ELCEN must ensure rigorous project management to avoid losing the non-reimbursable European funding. In the coming period, clarifications requested by bidders and the technical evaluation of proposals will dictate the pace of implementation. The successful completion of the new plant at CTE Grozăvești will set an essential precedent for future planned investments at CTE Sud and CTE Vest, redefining the capital's energy security for decades to come.
