The flood of cheap Marcellus Shale gas driving massive construction of new natural gas power generation capacity could wreak havoc in the PJM power market, Moody’s Investors Service suggests in a new report. Two of the nation’s largest power markets, Texas and California, already pose a “distressed environment” for unregulated power companies owing to declining […]

Sitting on a panel during the Bloomberg New Energy Finance Summit in New York City on April 24, Michael Bloomberg proclaimed that carbon capture and storage (CCS) is “total bullshit.” That statement was not received well by Trude Sundset, CEO of Gassnova, Norway’s state enterprise for the development of CCS. “There’s a whole new world […]

An inlet air cooling (IAC) system offers one of the most cost-effective ways to improve gas turbine (GT) performance—especially during the peak hours of hot summer months. After all, GT output depends on

New York’s electricity system and markets face a blizzard of changes, driven by policy, politics, and economic forces. The New York Independent System Operator and the New York State Energy Research and

Power plants are complex systems with countless moving parts, and in turn, countless opportunities for things to go wrong. With the advent of 3-D printing technology, repairing or replacing those moving parts

In two separate actions over the past 24 hours, the D.C. Circuit granted the Environmental Protection Agency’s (EPA’s) request to suspend cases challenging the Clean Power Plan and the Mercury and Air Toxics Standards (MATS).   The orders are the latest in a series of similar actions over the past month by the D.C. Circuit that […]

As Dynegy moved this week to assume full ownership of two struggling Ohio coal plants it co-owns with AES Corp. subsidiary DPL Inc., the company’s CEO reportedly said it is mulling withdrawing its presence from downstate Illinois owing to the state’s intervention to keep its nuclear plants running. Dynegy CEO Robert Flexon told Crain’s Chicago Business […]

Rain and snow has returned to California, ending the record-setting drought with record-setting precipitation. The drought led to forest fires, dead orchards, and brown lawns. It also took a big bite out of ratepayers’ wallets and increased global warming emissions, due to the loss of low-cost, zero-emission hydropower. In a study released April 26 by […]

Natural gas supply and price, along with lower electric demand and the growth of renewables, have been far more responsible for the decline in the U.S. coal industry than environmental regulations, according to a new study by Columbia University’s Center on Global Energy Policy and the Rhodium Group, a New York consulting firm. That means […]

GE Power signed a landmark deal to provide operations and maintenance (O&M) services for 10 power plants with a combined capacity of 11 GW. Sonelgaz SPE, a state-owned utility in charge of electricity and natural gas distribution in Algeria, owns the facilities. The agreement includes technology upgrades designed to enhance energy efficiency—allowing more than 420 […]

The U.S. Energy Information Administration (EIA) expects natural gas–fueled electricity generation will exceed all other fuel sources once again this summer, marking the third year in a row that gas has been the leader. However, the EIA anticipates electricity generation from both gas and coal will be less this summer than in 2016. The reason […]

The Navajo Generating Station can continue to be competitive under a reduced-price fuel proposal through 2040, said Peabody Energy, the coal giant which owns a coal mine currently fueling the Arizona plant. The utility owners of the Navajo plant on February 16 voted to shut down the 2,250-MW coal-fired power plant in December 2019. The […]

Exelon Corp., the nation’s largest nuclear generator, reinvented itself amid recent power pricing swings, market inequities, and policy worries that are challenging its “very existence,” a high-ranking executive told attendees at the ELECTRIC POWER Conference and Exhibition in Chicago this week. Bryan Hanson, president and chief nuclear officer for Exelon Generation, who gave the annual […]

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 […]

Russia Marks Milestone with Commercial Operation of Third-Generation Reactor. After nearly a decade of construction, the first advanced third-generation VVER-1200 nuclear reactor began commercial operation on

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 […]
