The conversation at the ELECTRIC POWER Conference and Exhibition, as underscored by comments made in its keynote address and at the annual event’s executive roundtable, was optimistic yet cautious, owing to

Two nuclear plants owned by Exelon Corp. in Illinois and Pennsylvania failed to clear PJM Interconnection’s latest annual capacity auction, putting one of those financially crippled units at risk of early retirement. Meanwhile, procurements for solar, wind, and demand response fell dramatically compared to last year, and drastic price declines could roil the market for […]

President Donald Trump wants to balance the federal budget in 10 years, and it appears he believes that to do so, deep cuts to the nation’s energy research funding are needed. The administration’s fiscal year 2018 (FY18) budget request, released Tuesday, May 23, cuts funding for the Department of Energy (DOE) by $1.7 billion, a […]

Virginia’s governor has directed the commonwealth’s environmental quality agency to establish regulations to curb its carbon emissions from power plants via a carbon trading scheme by the end of this year.  Executive Directive 11 signed by Gov. Terry McAuliffe (D) on May 16 instructs the Department of Environmental Quality to develop a proposed rule to […]

Detroit-based DTE Energy wants to slash its carbon emissions by more than 80% from 2005 levels by 2050, a reduction it said is in line with broad targets identified by scientists to address climate change.  The company said on May 16 that it plans to substantially increase investments in renewables, transition its baseload capacity from […]

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 […]

The Environmental Protection Agency (EPA) has announced it is working on guidance to give states the flexibility in implementing programs for the management of coal combustion residuals (CCR) disposal. In an April 28 letter to state governors, EPA Administrator Scott Pruitt described the agency’s steps to implement a “new authority” for authorizing state CCR management […]

Freshly reeling from a statewide blackout, South Australia’s government in March released an energy plan that seeks to cut its reliance on an electricity interconnector with eastern Australia that feeds the

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 […]

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 […]

The Trump administration is “closely” reviewing the Environmental Protection Agency’s (EPA’s) final cost consideration finding for its Mercury and Air Toxics Standards (MATS) to determine whether it should reconsider the rule or some part of it, it said in an April 18 federal court filing. The EPA filed a motion with the D.C. Circuit urging […]

The Department of Energy (DOE) issued an unprecedented emergency order on April 14 to keep open a power plant that had been slated for shutdown under the Mercury and Air Toxics Standards (MATS) in a bid to secure electric reliability. The DOE’s order was issued under the Federal Power Act Section 202(c). It inaugurates the […]

The Barack Obama administration waged war on the coal industry, but that’s all over now, recently confirmed Secretary of Energy Rick Perry told the National Coal Council (NCC) during its annual spring meeting. The NCC is an advisory board to the secretary of energy tasked with providing expert advice on matters of the coal industry. […]

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 Environmental Protection Agency (EPA) will review and reconsider revisions to technology-based effluent limitations guidelines (ELG) and standards finalized by the Obama administration in September 2015. Power generators around the nation have been readying to comply with the rule that sets the first federal limits on the levels of toxic metals in wastewater discharges from […]

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 […]

A coalition of 24 states and localities have urged a federal court reviewing the merits of the Environmental Protection Agency’s (EPA’s) Clean Power Plan to stall the agency’s recent motion to suspend a case challenging the controversial rule. West Virginia v. Environmental Protection Agency (No. 15-1363) is arguably the most important set of environmental cases […]

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 […]

A comparison of coal power plant fleets from China, the European Union (EU), Japan, and the U.S. by the International Energy Agency’s (IEA’s) Clean Coal Centre yields surprising insights into efforts these

China has brought 24 of its 36 operating nuclear reactors online at a breakneck pace since 2010, but there are signs it may roll out future plants that are still under construction more slowly, owing in part

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

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

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

Cyclic operating conditions can be problematic for many coal-fired power plants that were designed to run as baseload units. Implementing a combustion and boiler performance management program can help ensure

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
