The U.S. Environmental Protection Agency (EPA) has moved to shift capital planning and permitting timelines for the nation’s remaining coal-fired power units, acting on two measures targeting wastewater discharge under the Clean Water Act, and separately, air-quality visibility programs and the Clean Air Act. On Sept. 29, the EPA issued a proposed rule and companion […]

PPL subsidiaries Louisville Gas and Electric Company (LG&E) and Kentucky Utilities Company (KU) have proposed to upgrade environmental controls at a 1974-built coal unit, build two new gas-fired power plants at a combined cost of $2.8 billion, and add 400 MW of battery storage. The measures seek to significantly boost the companies’ capacity to ready […]

Southern Co. subsidiary Georgia Power has proposed a pivot toward extending the life of several existing coal and natural gas-fired power plants into the late 2030s—well beyond previous retirement timelines—citing rising electricity demand, regulatory constraints, and grid reliability risks. The utility’s 2025 Integrated Resource Plan (IRP), filed with the Georgia Public Service Commission (PSC) on […]

A transformer explosion at Eskom’s coal-fired 3.6-GW Matla Power Station in Mpumalanga, South Africa, on Dec. 12 injured nine employees, including one critically. The incident, caused by a ruptured high-pressure steam pipe, has underscored challenges faced by Eskom’s generating fleet, even as the state-owned maintains its suspension of load-shedding. The incident, reported at 5 p.m. […]

In an unprecedented move, the U.S. Environmental Protection Agency (EPA) on April 25 simultaneously finalized four major environmental rules covering greenhouse gases (GHG), air toxics, wastewater discharges, and coal combustion residuals from fossil fuel-fired power plants. Among the rules is the EPA’s final Carbon Pollution Standards, which marks the agency’s third attempt to broadly curb […]

Have you heard about the cobra effect? During the colonial era, Delhi had a major cobra issue. The then-British government announced a bounty for dead cobras to reduce the number of snakes on the streets. Entrepreneurial spirits rose as people started breeding cobras and offered a dead one on the bounty. Money given on bounty […]

Despite a dismal outlook for coal, countries with substantial coal fleets are intensifying efforts to develop new technologies and operational capabilities to improve coal power’s environmental impact

Mitsubishi Power has successfully demonstrated partial load and full load combustion of a fuel blend with 30% hydrogen (by volume) in a grid-connected J-series Air-Cooled (JAC) gas turbine. The achievement closely follows the completion of a combustion test on an ammonia single-fuel burner for coal firing by Mitsubishi Heavy Industries (MHI), Mitsubishi Power’s parent company. […]

Pingshan Phase II, a cutting-edge 1.4-GW ultrasupercritical coal-fired unit, achieves a remarkable net efficiency of 49.37%—making it the world’s most efficient coal-fired power plant. The state-of-the-art

The International Energy Agency (IEA) expects investment in clean energy technologies, including “renewable power, nuclear, grids, storage, low-emission fuels, efficiency improvements and end-use renewables and electrification,” to exceed $1.7 trillion in 2023, the most ever. Yet, even as clean energy investments grow, more than $1 trillion is expected to be invested in unabated fossil fuel […]

NTPC, India’s largest energy conglomerate and its largest coal generator, in March commissioned the country’s first supercritical coal-fired plant equipped with an air-cooled condenser (ACC). The effort

The Environmental Protection Agency (EPA) is proposing more stringent discharge standards for three types of coal power plant wastewater as part of an update to its Effluent Limitations Guidelines (ELGs). However, the agency also proposed compliance flexibilities, and in a separate direct final rule, moved to extend a deadline to allow more coal plants to […]

The recent shake-up in natural gas markets and their ensuing impact on energy security, and geopolitical tension, dramatically altered the trajectory of global coal-fired generation, sending it soaring to

The Environmental Protection Agency (EPA) is readying a regulatory sweep targeting more stringent limits on traditional pollutants that could accelerate coal power plant closures. A coal trade group estimates that even without new rules, 86 GW of coal generation is slated to retire by 2030. While the U.S. Supreme Court in June curtailed the EPA’s […]

Many coal-fired power plants are being asked to ramp output up and down regularly, and often to levels less than units were originally designed to operate at. Implementing a Unit Flexibility and Asset

Pennsylvania, a major power producer that relied on fossil fuels for 66% of its net power generation in June, plans to maintain its nuclear generation at current levels until it can ramp up other carbon-free supplies to 100% by 2050, the state’s Sept. 22–released 2021 Climate Action Plan suggests.  The measures are part of a […]

The Virginia State Corporation Commission (SCC) on Aug. 23 rattled American Electric Power’s (AEP’s) plans to operate the 2.9-GW John Amos and 1.3-GW Mountaineer coal power plants through 2040 when it partly denied cost recovery for expenses that the West Virginia plants need to comply with the federal Steam Electric Effluent Limitations Guidelines (ELG) rule. The […]

GE said it will exit the new-build coal power market, subject to applicable consultation requirements. “GE’s Steam Power business will work with customers on existing obligations as it pursues this exit, which may include divestitures, site closings, job impacts and appropriate considerations for publicly held subsidiaries,” the company said in a Sept. 21 announcement. It […]

The International Energy Agency’s (IEA’s) November 2019–released World Energy Outlook 2019 (WEO2019) is studded with interesting findings about emerging trends in the power sector. Here are 10 from the

New coal power plant technology is being developed by various companies around the world, but there are some pretty efficient and reliable designs already commercially available. Circulating fluidized bed

Coal combustion was responsible for more than 0.3 degrees C of the 1-degree C surge in global average annual surface temperatures above pre-industrial levels—and that makes coal the single largest source of the global temperature increase, the International Energy Agency (IEA) says in a new report.  The finding, outlined in the IEA’s Global Energy & […]

The Senate on February 28 officially confirmed Andrew Wheeler to be administrator at the Environmental Protection Agency (EPA) on a 52–47 vote, mostly along party lines. The nomination of Wheeler, a former coal lobbyist, was controversial, with many lawmakers and environmentalists criticizing his ties to the coal industry.  Wheeler has held the role in an acting […]

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

Reliability and cybersecurity ranked as the two most important issues currently confronting the electric industry, according to surveys completed by 672 qualified utility, municipal, commercial, and community stakeholders for Black & Veatch’s “2016 Strategic Directions: Electric Industry Report.” It’s not particularly surprising to see reliability rank at the top of the list. “Reliability has always […]

China’s once-booming coal power sector is facing an existential challenge as continued breakneck expansion of new capacity is colliding with flattened growth in power demand, despite increasingly strenuous government efforts to put the brakes on new construction. According to a pair of new studies, China’s overcapacity in coal-fired generation could reach a staggering 400 GW […]

The Mercury and Air Toxics Standards (MATS) will remain in effect as the Environmental Protection Agency (EPA) works on a final cost finding, the U.S. Court of Appeals for the D.C. Circuit ordered on Dec. 15. The court noted in a two-page order that the EPA “has represented that it is on track to issue […]
