We’ve all probably purchased a “lemon”—an item that didn’t work as advertised—but when that lemon is a $2.1 billion power plant, you can’t just return it. For Longview Power’s management team, taking a “belts-and-suspenders” approach to problem-solving allowed them to identify root causes, make changes, and convert their lemon into “lemonade.” Most people expect a […]

Now that the political conventions are over and Americans must choose between two presidential candidates, the rhetoric around coal’s future continues to heat up. What neither candidate is telling you, however, is that no matter who is elected in November, no matter what the makeup of the next Congress is, America’s coal age is over. […]

Power and utility deals through Q2 2016 are already outstripping full-year totals for previous three years.

A federal appeals court has stayed a regional haze rule finalized by the Environmental Protection Agency (EPA) earlier this year that had threatened to close up to 8.4 GW of coal-fired power capacity in Texas. In a unanimous ruling on July 15, the U.S. Court of Appeals for the Fifth Circuit granted a motion for […]

Southern Co.’s Kemper County energy facility—the only carbon capture and storage (CCS) integrated gasification combined cycle (IGCC) power plant that is under construction—is producing syngas using lignite. The plant marked its most significant milestone to date on July 14, said Southern Co.’s Mississippi Power. It means that the first-of-its-kind technology to convert locally mined lignite […]

China is preparing to expand nationwide a ban on new coal plant construction announced in April in an attempt to further rein in overcapacity and boost utilization of renewable energy, according to a report in Australian Financial Review. This spring, China’s National Development and Reform Commission and National Energy Administration suspended or slowed plans for […]

Many operators are perfectly happy with their trusty red and green HMIs and can’t imagine why they should give them up for a dull greyscale display. When they take a closer look, they usually find out that grey is beautiful.

Witnesses at a Congressional hearing raised concerns about the complexity, costs, legality, and feasibility of the 3,900 final rules published by the Environmental Protection Agency (EPA) during the Obama administration. A large portion of those rules affect the power sector, but none are more contentious than the Clean Power Plan, regulatory and citizen interest experts […]

A large fire at the Grand River Dam Authority’s (GRDA’s) Chouteau, Okla., coal-fired power plant was triggered by a string of unfortunate events shortly after a storm passed through the region on July 1. Justin Alberty, GRDA corporate communications director, told POWER that the fire started at around 7 p.m. that night. He said GRDA […]

The niche alternative energy industry that generates power from hazardous piles of coal waste that litter the U.S. is facing an environmental Catch-22. The torrent of coal mined and processed in the U.S. since

Fuel blending and switching has become the norm in response to regulatory and market forces, but many older boilers were designed for a particular fuel. Understanding the effects of different fuels on

Power plants are familiar with using continuous emissions monitoring systems (CEMS) to monitor pollutants, but these devices also may be able to measure heat rate—which could be handy for future compliance with the Clean Power Plan. Continuous emissions monitoring systems (CEMS) are used to monitor power plant flue gas emissions as a means to comply […]

The years between 2002 and 2012 are called Golden Decade for the coal industry in China. After May 2012, the coal industry fell into depression. In the Golden Decade, a large amount of social capital inflow

Plant wastewater treatment is not what it once was, and changes in the Environmental Protection Agency’s effluent limitations guidelines (ELG) have added a host of new wrinkles. A panel of power plant experts discussed what plant managers are planning and doing to keep things running smoothly within the new rules. For more than three decades, […]

Fuel Loading Begins at Kudankulam 2. Nuclear Power Corp. of India (NPCIL) began loading the first of 163 fuel assemblies into the core of the second VVER-1000 reactor of the Kudankulam nuclear power plant in Tamil Nadu, India, on May 11. The 1,000-MW unit will begin generating power pending approval from the Atomic Energy Regulatory […]

Fuel cells are a rapidly expanding option for distributed generation, with fuel cell–based power plants now being deployed in capacities into tens of megawatts (see “59-MW Fuel Cell Park Opening Heralds

Eskom operates 23 power stations in South Africa with a total capacity of more than 42 GW. It supplies about 95% of all the electricity used in the country. One of its coal-fired power stations was experiencing frequent boiler tube fatigue failures in the hopper section—the bottom part of the boiler—of all six units. The […]

Now that power plant operators have some experience under their belts related to Mercury and Air Toxics Standards (MATS) compliance, it’s time to reevaluate the options for demonstrating compliance. Starting

When owners of the Big Stone Plant researched air quality control system technology, they considered all available options and eventually settled on a design that was not in widespread use. Now that the

Rush Island Energy Center has successfully fired Powder River Basin (PRB) coal for two decades, as proven by the plant’s excellent performance stats, dedication to minimizing its environmental footprint, and sterling safety record. The PRB Coal Users’ Group top award recognizes the plant staff’s long-term dedication to continuously improving its safe handling and efficient combustion […]

Projections that coal utilization will decline faster than previously forecast have spurred Babcock & Wilcox Enterprises (B&W) to shed 200 jobs and restructure its traditional power business that serves coal-fired power generation in a bid to reduce overhead and improve efficiency. The Charlotte, N.C.–based energy and environmental technology and service company said on June 28 […]

The world’s power sector last year emitted a third of global sulfur dioxide (SO2) emissions, 14% of nitrogen oxides (NOx), and 5% of total particulate emissions (PM2.5), but those emission values have fallen drastically over the last decade even though coal power generation has seen a surge, the International Energy Agency (IEA) said in a […]

The U.S., Mexico, and Canada today announced an unprecedented goal to procure 50% of North America’s total power generation from renewables, nuclear, carbon capture and storage (CCS), and energy efficiency technologies by 2025.
