Győrhő, Hungary

The Győrhő combined heat and power (CHP) plant, which supplies power to the city of Győr in Hungary and heat to the city’s district heating system, is an example of fast-track supply in two phases. The total plant features three Wärtsilä 18V34SG gas engines, which produce an aggregate output of 17 MWth and 18 MWe.

The first two engines were supplied to the site in the summer of 2002 and phase one was handed over in November 2002. The third engine for phase two was delivered at the beginning of June 2003. The whole power plant became fully operational in early November 2003. A 5-year maintenance agreement was included in the contract. The operation supervision from Wärtsilä ensured smooth and trouble-free operation from the very beginning.

The CHP plant was engineered, supplied, built and started up in close teamwork involving the Győrhő district heating company, Wärtsilä and the contractors. Commenting on the Wärtsilä solution, the client specifically singled out the careful design of the complex but flexible heat recovery automation system, which contributed significantly to the plant’s rapid commissioning. The heat recovery system is designed to allow continuous operation and automatic adjustments to varying district heating water and ambient temperature conditions. The carefully designed instrumentation and pro-active logics immediately adapt to prevailing conditions, keeping the performance of the plant at an optimal level in a wide range of conditions.

“The Győrhő gas power plant is the first in Hungary to be self-financed, i.e. through its own capital and bank loans,” states Miklós H. Szováti, Managing Director of Győrhő Kft. “The local district heating system has supplied 260 MW of heat for local consumers in Győr since 1969. The new gas power plant, with an output of 18 MW of electricity and around 17 MW of heat power, meets our summertime heating needs. Since coming on stream in November 2002, it has performed to our complete satisfaction with 97.7% availability and 99.3% reliability. “More than 150 gas-engine power plants have been installed in Hungary since 1989, giving a total power output of around 180-200 MW. The gas power plant in Győr has the highest output and also the best availability,” he adds.
