EPA sets emission standards for new combined cycle plants

The U.S. Environmental Protection Agency (EPA) recently issued a long-awaited revised proposal for Clean Air Act standards to curb carbon pollution from new power plants. The rule sets separate standards for new gas-fired and coal-fired plants.

MHI operates pressurized SOFC-MGT hybrid system for an uninterrupted 4,000 hours

Mitsubishi Heavy Industries, Ltd. has achieved 4,000 hours of uninterrupted operation of a 200 kW class pressurized hybrid (combined-cycle) power generation system incorporating solid oxide fuel cells (SOFC) and a micro gas turbine (MGT). The company has been operating the hybrid system since March at Senju Techno Station, a facility in Tokyo operated by Tokyo Gas Co. Ltd., and it has now confirmed its stable power generation performance: generating-end output of 206 kW AC (alternating current) and 50.2 percent thermal efficiency.

GE to supply natural gas-fired systems worth $1.9 billion to Algeria

GE recently signed three contracts totaling $2.7 billion with SPE, a unit of Sonelgaz to supply heavy-duty combined-cycle gas turbine and aeroderivative gas turbine technology for nine power plants totaling 9 GW in Algeria.

Wood Group GTS wins GE LM6000 controls system contract in Arizona

Arizona Electric Power Co-Operative (AEPCO) has recently awarded Wood Group GTS a contract to replace a turbine control panel at AEPCO's 615 MW Apache Power Station in Benson, Arizona. The proprietary and aging Mark VI Millennium control panel will be replaced with an open-architecture Rockwell ControlLogix platform fitted to a GE LM6000PC dual-fuel enhanced Sprint gas turbine.

Two Siemens Flex-Plant 10 combined cycle islands power California with 550 MW

NRG Energy Inc. and Siemens Energy Inc. recently dedicated the El Segundo Energy Center located near Los Angeles, California. This is the second Flex-Plant to open in California after the nation's first in Lodi that went into commercial operation last year. Siemens Energy has supplied and commissioned the two Flex-Plant 10 combined cycle power islands. In total, they have an installed capacity of 550 MW – enough to supply efficient and flexible electricity to approximately 450,000 Californian homes.

Rolls-Royce wins gas turbine design contract for UK Royal Navy’s combat ship

Rolls-Royce has been awarded a contract recently to design the gas turbine system for the Royal Navy's future Type 26 Global Combat Ship, which will, subject to contract, feature the world's most powerful marine gas turbine, the Rolls-Royce MT30.

The MT30 is derived from Rolls-Royce aero engine technology and builds on over 45 million hours of operating experience. Producing 36 to 40 MW, it is the world's most powerful marine gas turbine and has the highest power density – a key factor in naval propulsion where delivering a high power output in a compact space is essential.

MHI to supply M701F4 gas turbines for Uzbekistan's GTCC power plants

Mitsubishi Heavy Industries has been awarded a contract for supply of its M701F4 gas turbine and generators for installation at two gas turbine combined-cycle (GTCC) power generation plants which Uzbekenergo is constructing in Uzbekistan. Featuring a 320MW class M701F4 gas turbine, steam turbine, heat recovery steam generator (HRSG) and generator, the two GTCC power plants will support the country's robust electricity demand.

MHI to supply six M501J gas turbines for a 2,600MW plant in Taiwan

Mitsubishi Heavy Industries, Ltd. has been awarded an order recently to supply six J-Series (M501J) gas turbines for a 2,600MW natural gas-fired combined cycle power generation plant being built by Taiwan Power Company in Taiwan. The company's 60 hertz M501J gas turbine has achieved a turbine inlet temperature of 1,600 degrees Celsius, and is a high-efficiency gas turbine.

GE to provide gas turbines for 360MW Turkish fast-track project

Helping to meet Turkmenistan’s growing power requirements, GE will provide its aeroderivative gas turbine technology to Çalık Enerji, an energy company in Turkey. Three power plants will be built at the Akhal, Mary and Lebap sites as part of a 360-MW fast-track project, with the Akhal and Mary sites expected to enter commercial service by the end of 2013 and Lebap to follow in February 2014.

TAS Energy delivers TIC modules for Australian LNG project

TAS Energy recently delivered major Turbine Inlet Chilling (TIC) modules to Bechtel for an LNG project in Australia. The TIC system will deliver 14 000 TR (49 238 kWth) to the gas turbines running the compressors for the liquefaction process to ensure consistent inlet air temperature in the turbine fleet. 

One of the world’s first TIC application used in the LNG process, the concept is said to improve the gas turbine’s output when high ambient temperatures negatively impact its efficiency and performance, thus improving the overall plant’s MW production.
