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

The Lodi Energy Center (LEC) is a 296-MW 1 x 1 combined cycle plant in Lodi, Calif., just north of Stockton and east of the San Joaquin River delta (Figure 1). From the outside, there’s little to distinguish

Selective catalytic reduction (SCR) systems installed in steam generators for NOx reduction are ordinarily designed for full boiler load conditions, when SCR inlet temperatures normally exceed unit-specific

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 […]

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 […]

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 […]

The dramatic collapse in the price of oil—currently flirting with sub-$40/barrel levels—has naturally produced an explosion of commentary on its short- and long-term effects. One curious, though predictable, narrative is starting to emerge from the environmental left: The price collapse is the death knell to shale oil, and the U.S. oil boom—which was never a […]

Michigan Gov. Rick Snyder announced a series of deals designed to eliminate a costly utility rate payment in the state’s Upper Peninsula (UP), while providing long-term, cost-effective energy reliability for the region. The solution was developed through four principle agreements. In one, the electric utility businesses now owned by We Energies and Integrys (doing business […]

The Obama administration announced on Jan. 14 that the Environmental Protection Agency (EPA) will propose new regulations to cut emissions of methane from the oil and gas industry, as well as other measures, with a goal of reducing total U.S. methane emissions 40% to 45% by 2025. The proposed rule is expected this summer. Emissions […]

Düsseldorf, Germany–based energy supplier E.ON announced on Jan. 12 that it would sell its Italian coal and gas generation assets to Energetický a Průmyslový Holding (EPH), a Czech energy company. E.ON has been looking for a suitor for the Italian operations since at least Nov. 30 when it announced it was embarking on a new […]

Moving natural gas through long-distance pipelines requires substantial energy, and much of that energy is lost when the gas must be reduced in pressure before it reaches end users. But a new project may demonstrate a way for gas transmission companies to recapture some of that energy and improve the efficiency of the letdown process, […]

The breathtaking collapse in crude oil prices this past fall, which has seen benchmark prices drop from over $110 a barrel last year to under $50 this past week, has had little effect on U.S. natural gas production, which continues to set records. According to data from the Energy Information Administration (EIA), U.S. dry natural […]

Much has been made recently of Mexico’s energy sector reforms, and because those reforms are still in being implemented, it can be useful to compare their progress with the outcome of previous reforms in Latin America. (A condensed version of this material appears in the January 2015 print issue of POWER: “Can Mexico’s Electricity Reform […]

The rate of introduction of new gas turbine products has accelerated, and the speed of change creates challenges for engineering, procurement, and construction (EPC) contractors who are also coping with a

In mid-November, members of the POWER Generating Company Advisory Team responded via email to the following set of questions. Their comments have been edited for style. POWER: What changes in your fleet’s

The urge to merge, a key feature of the power industry for the past 20 years or so, showed no signs of slowing in 2014. Major players sought to beef up their asset portfolios and diversify their generating

Renewables’ share of the global power mix is slated to overtake coal to become the largest source of electricity by 2040, the International Energy Agency (IEA) projects in its 2014 edition of the World

Energy market dynamics in the U.S. continue to evolve. Regulatory developments, advancements in power plant technology, and fuel dynamics are transforming the industry. Although the outcome of these

“When pigs fly” is a figure of speech used to express disbelief that a particular situation will ever come to pass. For the power industry, several recent and emerging developments are the equivalent of

The power generation market continues to evolve due to fundamental changes in market forces. Ongoing opportunities exist to partner with utilities to support this evolutionary process. Leadership Is Key for

In 2013 the Mexican government passed historic reforms that eliminated the state’s monopoly on the energy sector in an effort to attract private investment. In the electricity sector, reform was sold on the

The Florida Public Service Commission (PSC) on Dec. 18 approved Florida Power & Light’s (FPL’s) request to invest in natural gas wells in Oklahoma. NextEra subsidiary FPL, one of the largest natural gas consumers in the country—it burns more gas than any other electric utility, about 2 Bcf/d—filed the request this past June. The plan […]
