Siemens Energy, Inc. and Calpine Corporation signed an agreement to upgrade approximately one-third of the independent power producer’s fleet of Siemens F Class gas turbines, with an option to upgrade additional units. The Siemens technology upgrades on each unit are intended to add incremental capacity while improving the efficiency of the entire engine. Calpine intends to implement these upgrades over the next several years. The contract value is more than USD110 million.
Calpine currently operates 38 Siemens F Class gas turbines in the United States, primarily in California and Texas. The thermal performance upgrade to the Siemens SGT6-5000F combustion turbine is intended to increase base load power, while significantly improving the overall base load heat rate. The scope of the technology upgrades for the turbines will vary from unit to unit, but will generally include combustion turbine components, operational enhancements and installation services.
“Increasing efficiency through the modernization of the existing power generation fleet helps our customers produce environmentally compatible electricity to meet the nation’s future energy demand,” states Randy Zwirn, CEO of Siemens Energy’s Service Division. “Siemens considers these upgrades to be an important step in helping make Calpine’s fleet a more competitive force in the changing energy landscape.”
"Calpine applauds Siemens' design of this highly efficient retrofit that allows us to upgrade our turbine-generators. We look forward to providing this clean, reliable and efficient additional capacity to our customers throughout the United States," said Tom Webb, Calpine

To satisfy growing power demands two CX 501 KB7 gas turbine power units by Centrax Ltd. have been installed at the field. Container power units are designed on the base of Rolls-Royce engines rated at 5.2 MW each. Gas turbine power units operate in simple cycle, the fuel is casing-head gas from the field. Generator output voltage is 6.3 kW.
The customer for the project is Novosibirskneftegas oil and gas company, the general designer and contractor is Dominanta-Energy JSC.
Alstom has been awarded a contract by RWE npower plc for the design and construction of a 2000 MW gas-fired combined-cycle power plant in Pembrokeshire, Wales in the United Kingdom.
The plant will be built on the site of the previous oil-fired power station and will include five Alstom GT26 turbines and accompanying core components. With an output of approximately 2000 MW, it will be the largest and one of the most efficient of its kind in the UK, capable of supplying power to around three million homes.
This project is the second one that Alstom has signed with RWE npower in the UK. Alstom is also building the Centrica's Langage and E.On's Grain power plants. Including this latest contract, these four power plants will add close to 6 GW of new electrical power to the UK grid.
Approximately 40% of the UK energy fleet was built before 1975 and will need replacement in the short to medium term.
The general contractor for the project is Vera Ltd. The power plant consists of four GE Energy Jenbacher gas engines JMS 612 power units each producing 1817 kW of electric and 1715 kW of thermal power. Each power unit is based on JMS 612 GS-N.LC engine. The station operates in trigeneration cycle generating hot water and cold for climate control.
Forth unit of Ali Abad power plant which is located in north of Iran, was manufactured. TUGA is supposed to supply 6 Gas turbine V94.2 with power output 162 MW (ISO Condition) for each unit and total capacity 970 MW of whole plant. Ali abad power plant located in North of Iran.
The development of Illichivsk fat-and-oil works was impossible without additional power supply under the conditions when local power company runs a shortfall. As a result the owner of the enterprise commissioned autonomous CHP plant designed on the base of four JMS 420 GS power units equipped with J 420 GS engines and Cummins PI 734 F generators. Power unit capacity is 1416 kW of electric and 1505 kW of thermal power.
The power plant with the capacity of 44 MW will be built by Iskra-Energetika JSC in Znamensk, Astrakhan Region. The project will be realized under the turnkey contract. The power plant will be designed on the base of two GTE-16PA2 power units. Heat-recovery steam generators will be manufactured by Belenergomash boiler plant, steam turbine - by Kaluga turbine works.
The customer and investor for the project is Eurasia-Energo Company, the general designer is Giprokislorod JSC. The commissioning is scheduled for 2010.
