An April 6–issued report released by the World Energy Council suggests that the single biggest worry among global energy leaders is commodity price volatility. Prices appear to be a big concern because of the “Grand Energy Transition” toward de-carbonization. Leaders in resource-holding countries, such as Saudi Arabia, are anxious about long-term economic models, if prices […]

Varnish buildup in oil systems and components can degrade performance and cause erratic valve operation. Some experts have conducted research and formulated new lubricants that could help solve those problems. One such oil proved highly successful during a five-year run at a gas turbine power plant. By eliminating the need for oil changes and valve […]

Most combined cycle professionals understand that a joint between grade 91 steel and an austenitic stainless steel is considered a dissimilar-metal weld. For that reason, it requires special welding

Today, some F-class operators continue to opt for rotor-out major inspections, which are cumbersome and inefficient. They involve complex lifts and moves of the rotor, as well as the need for substantial space

New technology is being used throughout the power industry to improve plant efficiency, predict trouble with degrading equipment, forecast weather trends, and train workers. A recent conference hosted by POWER

Cycling a combined cycle plant places additional stresses on all equipment, but the impacts extend beyond the gas turbine and heat recovery steam generator. Plant owners and managers are beginning to see

Continuous condition-based monitoring of electrical conductors and insulation is an effective way to reduce required plant maintenance activities, cut operating costs, and prevent unplanned shutdowns

Many elaborate planning tools are available to help managers prepare for power plant outages. However, there is something to be said for keeping things simple. One modest tool that some NRG Energy facilities

A power plant’s isolated phase bus is generally reliable, and therefore, maintenance is frequently overlooked. However, the system is too important to neglect. Assessing its condition during minor outages

Technology advancements and new regulatory requirements could reshape how power plant owners operate and maintain large power transformers. Experts outline emerging strategies and call attention to overlooked

State governors are not obligated to spend resources to comply with the Clean Power Plan, which has been stayed by the Supreme Court, a “guidance” letter from Environmental Protection Agency (EPA) Administrator Scott Pruitt says. The three-paragraph letter, dated March 30, notes that the Supreme Court set a “precedent” when it stayed the rule governing […]

Several U.S. states have passed, or are mulling, programs that expand state aid to financially distressed nuclear reactors in a bid to keep them open for economic and environmental reasons. Generators that operate in competitive wholesale markets are perturbed by these measures, which they say amount to nuclear “bailouts.” —Sonal Patel, associate editor (@POWERmagazine, @sonalcpatel) […]

Beijing, China—a city known for its dreadful air pollution—no longer has any large coal-fired power plants adding to the problem. The Huaneng Beijing Thermal Power Plant’s final unit suspended operations on March 18, marking the end of coal-fueled generation in the city. Beijing’s power is now being supplied by what Xinhua (the Chinese government’s official […]

The Trump administration released a blueprint of its proposed 2018 budget on March 16, likely setting off a major battle with Congress. The budget proposal, “America First: A Budget Blueprint to Make America Great Again” makes major cuts in non-defense discretionary spending over 2017. While funding for the Department of Defense is boosted $52.3 billion, […]

If President Donald Trump truly wants to revitalize the coal industry, he should continue to support the Department of Energy’s (DOE’s) Office of Fossil Energy’s research efforts, representatives of the coal industry said in a March 10 letter. “In light of recent calls for dramatic cuts to the federal budget, we want to stress that […]

India will open all 26 of its sedimentary basins to allow domestic and foreign investors to explore conventional and unconventional oil and natural gas resources in a bid to escalate its indigenous oil and gas production, reduce imports, and support a planned influx of renewable power. Union Petroleum and Natural Gas Minister Dharmendra Pradhan told […]

Regardless of recent federal support for a revitalization of coal in the U.S., “the economics are challenged,” Lynn Good, CEO of Duke Energy, said March 1 during a presentation at the U.S. Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) Energy Innovation Summit. “I think coal continues to be an important part of a […]

A bill signed by Minnesota’s Gov. Mark Dayton (D) on February 28 allows Xcel Energy to build a 786-MW combined cycle gas-fired power plant without approval from state regulators. The governor signed Chapter 5, House File 113, a bill that had bipartisan support of the state’s legislators, to allow the Minneapolis-based power company to move […]

Stricken by falling prices, producers of liquefied natural gas (LNG) are looking to exploit an emerging trend that integrates the fuel source with power generation. According to Houston-based international law firm Baker Botts, an increasing number of LNG power projects are emerging worldwide as a “new, viable medium” that offers a rapid but long-term power […]

The Donald Trump administration can look to the energy sector to increase federal revenue and offset the national debt in numerous ways, but there are pros and cons to everything, according to a panel presenting at the Cato Institute February 22. Carbon pricing has long been the preferred economic means of mitigating carbon emissions. A […]

Southern Co.’s Kemper County integrated gasification combined cycle (IGCC) project, stricken by steep cost increases and an in-service date delayed again to mid-March, isn’t economically viable in the face of projected long-term natural gas prices, the company said. Southern Co. subsidiary Mississippi Power reported that integrated operation of the facility’s two gasifiers and combustion turbines […]

In a final 52–46 vote, the Senate on Friday confirmed Oklahoma Attorney General Scott Pruitt as Donald Trump’s nominee to lead the Environmental Protection Agency (EPA). The vote was mostly along party lines. Every Republican present except Sen. Susan Collins (R-Maine) voted for Pruitt (Sen. John McCain [R-Ariz.] did not vote because he is at […]

The utility owners of the Navajo Generating Station (NGS) in Arizona have voted to shut down the 2,250-MW coal-fired power plant in December 2019. The decision to close the plant on tribal land near Page along the border with Utah was based on the “rapidly changing economics of the energy industry,” which has seen natural […]

What do we know as of February 1 about key Trump appointees responsible for administering White House policies affecting the power generation industry? Not much. As the Trump administration settles in, how his teams at energy and environment agencies will implement his policy agenda remains unclear, as does his agenda. At the end of January, […]

In a step that it hopes will be emulated by developers of new natural gas generation facilities in the U.S., NTE Energy has voluntarily committed to drastically slash greenhouse gas (GHG) emissions from the proposed 550-MW Killingly Energy Center facility in Connecticut—and to shut it down by 2050 unless it operates with no net GHG […]

A variety of approaches have been used to capture new benefits from combined heat and power (CHP) facilities. Some owners have transitioned to new fuels or added renewables to the mix, while others have implemented unique business models to spur development. As district heating systems are brought into the 21st century, the CHP sector seems […]

A wastewater treatment plant in the Danish city of Aarhus is reportedly producing enough power to cover all of the energy used for the whole water cycle in its catchment area—from water production and water

According to the International Energy Agency (IEA), global power production from combined-heat-and-power (CHP) technologies has stagnated since 2000, lagging far behind growth in conventional power technologies and commercial heat generation. Despite having an average efficiency of 59%, CHP’s share of global generation in 2013 stood at just 9% (Figure 1), the bulk of it at […]
