Entergy Louisiana’s two-unit, 560-MW combined cycle plant in Westwego, La., just outside New Orleans, completed construction on Dec. 26, both under budget and several months ahead of its original schedule

TIC to Build First U.S. J-series GT Plant. The Industrial Co. (TIC), a wholly owned subsidiary of Kiewit Corp. ,was recently awarded an engineering, procurement, and construction contract to build a gas

Originally, the modern combined cycle gas turbine (CCGT) unit was developed to act as a largely baseload source of generation due to its high thermal efficiency and low initial capital cost. But as markets

On Monday, the West Virginia Public Service Commission (PSC) approved the siting certificate for Moundsville Power LLC to construct a 549-MW combined cycle natural gas power plant in Marshall County. It will be the first to also burn ethane. The company is also touting the project’s role in helping to offset the effect of area […]

Pennsylvania seems poised to levy a severance tax on natural gas extraction after new Governor Tom Wolf proposed a change in the state’s treatment of gas production that could produce as much as $1 billion a year in revenue. The proposal would levy a 5% tax on the value of the gas at the wellhead, […]

“The coolest thing on Earth” is, according to its new director, a young federal agency that has a unique focus on pushing technology frontiers and an “unblinking attention” to market realities. One thing you can say for sure about the energy world, said Dr. Ellen Williams (Figure 1), incoming director of ARPA-E (Advanced Research Projects […]

The Massachusetts House of Representatives is considering a bill that would enact sweeping changes in the state’s energy mix, among them a tax to support construction of new natural gas pipelines. The bill is being pushed by legislators and business interests alarmed by the state’s rapid loss of coal and nuclear generation, and equally rapid […]

Combining electric power production with use of steam for heating, cooling, and industrial processes is an old idea that had a brief boom in the U.S., kicking off the rise of non-utility generation. Since then, combined heat and power, or cogeneration, has become a niche market player. What happened? In the late 1990s, the University […]

Despite its efficiency and environmental benefits, combined heat and power (CHP) generation has languished at around 10% of worldwide capacity for more than a decade. But a global review shows growth in some sectors and promising new technology on the way. The statistics are both eye-opening and somewhat depressing. Globally, according to the International Energy […]

As it struggles to grow its economy while improving air quality in urban areas, China is updating its energy delivery infrastructure. A key part of that plan is switching from coal-fired to gas-fired combined heat and power plants. To push efficiency even further, some plants are turning to synchronous clutches. The developed world has done […]
