Siemens overhauls turbine at 794-MW gas-fired plant in Hungary

Siemens has worked with owners to complete a major overhaul at an Hungarian gas-fired power plant. The German-based power manufacturer collaborated with MET Asset Management AG on work at the Dunamenti Power Plant in Százhalombatta, Hungary. Siemens Gas and Power replaced the entire rotor of the plant’s SGT5-2000E gas turbine and installed a new, state-of-the-art SPPA-T3000 control system.

The rotor exchange for the SGT5-2000E at the Dunamenti Power Plant led to an increase in output from 148 MW to 155 MW and increased the unit’s efficiency by approximately 0.8 percent. The turbine had already achieved 120,000 hours of operation and, with the new rotor, is now ready for the next 41,000 hours before the unit’s next scheduled outage services.
“Thanks to the fast and direct communication and information flow within our team and the excellent cooperation with the customer, we were able to execute this major project in just 51 days, a short time for such a big project,” said Vinod Philip, CEO of Siemens Service Power Generation. “We are delighted that we have delivered this state-of-the-art technology to Dunamenti, thereby contributing to an efficient and more reliable energy supply in Hungary.”
The Dunamenti Power Plant is the largest gas-fired power plant in the country with a capacity of 794 MW.  It was completed in 1998.

“We’ve run several modernization and maintenance development projects in the last couple of years in order to secure sustainable operation at the Dunamenti Power Plant,” said Péter Horváth, CEO of Dunamenti Power Plant. “As part of this agenda, the SGT5-2000E gas turbine manufactured by Siemens received a complete overhaul. Thanks to the maintenance, the SGT5-2000E turbine now guarantees additional 41,000 hours of operation for the power plant so we surely remain key energy supplier of the domestic energy market.”
