Siemens Powers Two Dutch Plants

Combined-cycle plants to provide reliable, efficient and competitive production

Posted on July 1, 2013

Dutch energy company Nuon has commissioned two combined-cycle gas turbine plants in the Netherlands with the capability of generating enough power for 1.5 million households.

The new gas-fired plants are located near the city of Amsterdam and use F-class turbines and technology supplied by Siemens Energy. In addition to turnkey construction, Siemens supplied each plant with an SGT5-4000F gas turbine, an SST5-5000 steam turbine, a hydrogen-cooled SGen5-2000H generator, the complete electrical equipment, and an SPPA-T3000 I&C system.

Hemweg-9, located in the Westport district of Amsterdam, has a capacity of 440 MW and an efficiency rating of 59%, the company said. The plant replaces the old 511 MW Hemweg-7 gas-fired facility, which was commissioned in 1979 but shut down last year. Hemweg-9 has been designed to allow for the retro-fitting of district heating equipment in the future.

The Diemen-34 plant is located to the east of Amsterdam – about 15 km from Hemweg – and has a generating capacity and efficiency rating similar to Hemweg-9, but is also capable of supplying 260 MW of heat, enough for 25 000 households..
