Elsaco Electronic and Clarke Energy are undertaking cogeneration projects in Arad and Constanța, Romania, using Jenbacher J920 FleXtra engines to replace aging equipment in district heating networks. These projects, part of Romania's energy infrastructure modernization strategy, are expected to deliver 85 MW electrical and 80 MW thermal power, reducing primary fuel consumption by 30%. Financed by the EU, the initiatives aim to improve network efficiency and prepare for the future use of hydrogen and biomethane mixtures. The modernization will bring substantial savings in operating costs, enhancing the resilience of urban energy networks and laying the groundwork for integrating advanced technologies. This shift towards more flexible and efficient infrastructures reflects Romania's efforts to modernize and diversify its energy sources, reducing reliance on outdated technologies. The country's focus on decentralized generation and the adoption of cutting-edge technologies are seen as essential steps to meet market demands and energy performance expectations, setting a potential model for similar projects in the region.
