Germany-based multinational engineering and electronics conglomerate Siemens Energy has completed two combined cycle power plants (CCPP) Hemweg 9 and Diemen 34 in the Netherlands.

Dutch utility Nuon, a part of Vattenfall, has officially inaugurated the 440MW Hemweg 9 located in the Westport district to the west of Amsterdam’s center and 435MW (260MW thermal capacity) Diemen 34 CCPP situated to the east of Amsterdam about 15km from Hemweg.

Hemweg 9 has replaced the Hemweg 7 power plant that was shut down at the end of 2012. The new CCPP will reduce carbon dioxide and nitrogen oxide emissions.

Siemens built the two power plants on a turnkey basis and equipped each facility with a F-Class gas turbine, SGT5-4000F gas turbine, SST5-5000 steam turbine, hydrogen-cooled SGen5-2000H generator, the complete electrical equipment, and SPPA-T3000 I&C system.

Both the CCPP have started delivering their first electricity to the Dutch power grid since mid of 2012.

Siemens Energy Gas Turbine Power Plant Solutions head Lothar Balling said the modern combined cycle power plants constructed in Amsterdam provide customers with numerous economic advantages.

"Their high efficiency makes it possible to produce more electricity from the same amount of fuel," Balling added.

"The district heat extraction assures our customer of additional revenue and the extreme service friendliness of our equipment minimizes maintenance-related production losses."
