Kaarsto Location: Norway Operator: Naturkraft AS Configuration: 420-MW, single-shaft CCGT block with SGT5-4000F gas turbine Fuel: natural gas Operation: 2007 HRSG supplier: Balcke-Durr T/G supplier: Siemens EPC: Siemens Quick facts: In the mid-1990s, Naturkraft was formed by Norsk Hydro, Statkraft, and Statoil to develop two gas-fired power plants and in Oct 1996, NVE gave the go-ahead for gas-fired CCGTs at Kaarsto and Kollsnes. In Oct 2000, the plants were approved by SFT, a decision appealed by several environmental groups. The government upheld the permits in Jul 2001, but the projects then languished until finally shaken loose by a combination of persistence on the developer’s part, substantial price spikes for hydroelectricity, and new agreements with the Storting on carbon dioxide treatment. In Sep 2004, Statoil withdrew from the consortium and in Jul 2005, Siemens received a turnkey order for the €245mn power station. Output is expected to be 2.3 TWh/yr.

Mongstad Location: Norway Operator: Dong Energy Configuration: 280-MW, 2+1 CCGT block with 9001E gas turbines CHP Fuel: natural gas, refinery offgas Operation: 2009 HRSG supplier: NEM T/G supplier: GE EPC: Dong Energy, Rambøll, Nederlandse Aardolie Maatschappij Quick facts: Mongstad is on Norway's west coast north of Bergen at the Statoil refinery. This first opened in 1975 and has been upgraded and modified ever since. It is the largest refinery in Norway and exclusively processes North Sea Crude. Power plant construction started in Jan 2007 and the plant began operations in Oct 2009. The electrical capacity is 280 MWe and the heat capacity is 350 MJ/s. Heat is used to produce steam and to pre-heat crude oil. Some electricity is used to power the Troll-A offshore drilling platform. In a second phase of power plant development, the world's first full-scale power plant CO2 capture and sequestration project is planned for operation from 2014.

Nya Öresundsverket Location: Sweden Operator: E.ON Sverige AB Configuration: 440-MW, 1+1 CCGT with 9001FB gas turbine CHP Fuel: natural gas, biodiesel Operation: 2009 HRSG supplier: NEM T/G supplier: GE, Alstom EPC: Hitachi Power Europe, Koch, FMT, August Prien, Cegelec Quick facts: Öresundsverket has been built out in three stages at a site in Malmo harbor. First were four coal-and oil-fired boilers and three steam sets designed and built by Sydkraft in the early 1950s. Due to a lack of cash after World War II, one of the steam turbines was paid for with dry milk. The plant ran regularly into the early 1970s. Stage-2 consisted of 70-MW steam set completed in 1957 while Stage-3 had two 80 MW gas turbines added in 1971/72. This made Öresundsverket northern Europe's largest thermal power plant with about 400 MW of electrciyy output and 250 MW of heat. In the early 1990s, the oldest steam sets were deactivated and the GTs were modernized. In Oct 2007, work got underway on the new CCGT block. First fire was on 7 Mar 2009 and full output was achieved in May with commercial operation planned in the fall. The new plant cost about SEK 3bn and about 45 companies were employed on the job at one time or another.

Rya Location: Sweden Operator: Göteborg Energi AB Configuration: 261-MW, 3+1 CCGT with SGT-800 gas turbines CHP Fuel: natural gas Operation: 2006 HRSG supplier: Alstom, Austrian Energy & Environment CZ T/G supplier: Siemens EPC: Siemens, NCC Quick facts: This CCGT plant meets around 35% of Goteborg's district heating demand and 30% percent of its power requirements. Overall plant efficiency of 92.5% saves about 600,000 tpy of carbon dioxide emissions. The Rya plant can operate in island mode if necessary and has the necessary equipment to pressurize Goteborg's DHS. Gas is supplied from Denmark. Siemens has a 7yr service agreement.
