The Dorog power plant and the district heating supplier Promtávhő Kft., both members of the Veolia Hungary group, provide district heating in several locations in the towns of Dorog and Esztergom. In addition to serving the residential population, the power plant supplies industrial steam to the Richter Gedeon Pharmaceutical Factory in Dorog.

Several successful investments have been made at the power plant. Based on the agreement concluded in 2011 between the power plant and SARPI Dorog Kft., which operates the hazardous waste incinerator on the outskirts of the city, the power plant receives steam from the environmental industry facility. This takes advantage of the synergies between the two sites, which are only a few hundred meters apart. As a result, Dorog’s environmental indicators have become much more favourable.
One of Veolia’s medium-term goals was to phase out coal firing by 2025. As a result, the coal-biomass boiler at the Dorog power plant has not been in operation since March 2023, thereby improving the plant’s emission values. Energy production is now carried out with gas boilers, but the coal-biomass boiler remains available as a backup.
In 2021, the power plant launched several large-scale, energy efficiency improvement projects, which were carried out between 2021 and 2024. In the first phase, one high-efficiency gas boiler was installed and commissioned in the autumn of 2022, which was followed by the installation and commissioning of two INNIO Jenbacher JMS 620 gas engines in the autumn of 2024. These developments have significantly improved the energy production efficiency of the power plant and its related environmental indicators, thus contributing to sustainable development.
