Debreceni Kombinált Ciklusú Erőmű Kft. operates the Debrecen Combined Cycle Power Plant.

E.ON Hungária invested 17 billion forints into building its combined-cycle power plant in Debrecen. The power plant came into operation in November 2000, one year after its cornerstone was laid. Debreceni Kombinált Ciklusú Erőmű Kft. was set up by E.ON Hungária Zrt. to build and operate the power plant.

This is the first power plant in Hungary to sell the electricity it generates directly to the regional electricity providers, E.ON Tiszántúli Áramhálózati Zrt., and the deregulated market rather than to state-owned electricity wholesaler MVM.

The state-of-the-art technology employed makes it possible to achieve an efficiency rate exceeding 80%, in contrast to the 35% efficiency figure for traditional power plants.

During the so-called cogeneration process, the natural gas burned in the gas turbine generates electricity directly. Hot flue gas, instead of being emitted to the environment, produces steam in a heat recovery steam generator, which is in turn utilized in the steam turbine to generate electricity. The facility's power output is 95 MW, coupled with a heat output of 90 MW.
