In the next 25 years, the world will turn increasingly to renewables and natural gas to meet energy demand, turning away from coal, according to the International Energy Agency’s (IEA’s) World Energy

Siemens claims to be paving the way for the next level of efficiency with the development of its HL-class gas turbine. In June 2017, the company announced it will validate the technology at Duke Energy’s Lincoln County site in North Carolina. Siemens is developing this class in an evolutionary development step derived from its proven […]

Earlier this year, GE’s Power Services achieved a significant milestone with its 9EMax gas turbine upgrade solution. The 9EMax completed initial validation testing and was offered commercially to gas turbine customers around the globe. The first 9EMax unit was installed at a customer’s site in Asia. “First fire is a critical test where the gas […]

A Michigan utility will build a $500 million natural gas-fired power plant on the site of an existing coal-fired plant in Lansing, and plans to retire the coal plant and another coal-fired facility in the town in the next few years. Lansing’s Board of Water & Light (BWL) announced the project December 18. The city-owned […]

A utility group on December 18 agreed to keep a coal-fired power plant in Colorado Springs, Colorado, open for at least a few more years, and its members said they are prepared to move forward with distributed generation and could import power to make up for the eventual retirement of the Martin Drake Power Plant. […]

Oman recently began operating a Wärtsilä-built power plant in the northern part of the country, part of more than $1 billion in power and energy projects being developed in the Arab nation. The Musandam Independent Power Project (IPP) is a 120-MW natural gas-fired plant (Figure 1) that can use light fuel oil as a secondary […]

A report released December 14 by the North American Electric Reliability Corp. (NERC) says power generation from natural gas-fired units and renewable sources such as solar and wind will provide enough electricity to offset the closures of U.S. coal-fired and nuclear power plants in the next decade. The agency’s 10-year outlook, part of its 2017 […]

Supercritical carbon dioxide (sCO2) cycles—which are inching closer to commercial applications for waste heat recovery, concentrating solar power, nuclear, and fossil energy—offer higher thermal efficiencies and power density than conventional steam Rankine and Air Brayton cycles in use today for power generation. But to realize these potentially game-changing cycles, common challenges associated with turbomachinery must […]

Energy Secretary Rick Perry has granted a 30-day extension sought by Federal Energy Regulatory Commission (FERC) Chairman Kevin McIntyre last week to give the regulatory agency more time before it acts on the controversial proposed Grid Resiliency Pricing Rule. In a strongly worded letter, however, he told FERC to act expeditiously to allay reliability threats to […]

GE Power said its 9HA.02 gas turbine reached a new milestone by exceeding 64% efficiency in combined cycle power plants. The company attributes at least part of the achievement to advances in additive manufacturing (3-D printing). “The HA is our most advanced gas turbine technology, and we’ve never stopped pushing the boundaries of what it […]
