CCGT Plants in Norway and Sweden
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: Mongstad Heat & Power AS
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, Rambřll, 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 Feb 2017, Statoil announed that it would close the CCGT plant after years of unprofitable operation with the expiration of hte gas-supply agreement on 31 Dec 1018.

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 tower 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 19 Mar 2009 and commercial operation began in Nov 2009. 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.
