Even so, the GE-led construction consortium made adjustments and delivered the state-of-the-art ultrasupercritical project on time […]

While it’s true that coal ash can be an environmental hazard if it’s not properly managed, there are a lot of positive uses for coal combustion products that actually provide benefits to the world. Many beneficial uses have been around for decades, but valuable new options are being developed, and some are starting to make […]

For all its record-breaking achievements for speed, innovation, and efficiency, the 3,960-MW Sasan Ultra Mega Power Project should have been a POWER Top Plant. But the unique project has been plagued by serious setbacks—including loss of life—that show how perilous the plant construction journey can be. A decade ago, India was suffering a power crisis […]

Duke Energy agreed to pay a $6 million fine under a new settlement reached with North Carolina’s Department of Environmental Quality (DEQ) for the February 2014 coal ash spill at its Dan River power plant in Eden. State regulators fined the utility $6.8 million in February, but Duke Energy challenged the decision, which was the […]

The Dutch parliament’s vote in favor of a motion to cut carbon emissions 55% by 2030 could spell the end of coal-fired power generation in the European nation. Although nonbinding, the measure would bring the Netherlands in line with agreements negotiated during the Paris climate talks that took place late last year. What it means […]

Oral arguments on the merits of the Environmental Protection Agency’s (EPA’s) Clean Power Plan were concluded before an en banc panel (10 judges, rather than the anticipated three) at the D.C. Circuit Court of Appeals on September 27. West Virginia v. Environmental Protection Agency (No. 15-1363) is arguably the most important environmental case in nearly […]

States, regulators, and market participants have in recent years called attention to a trend concerning uneconomic baseload generation in organized wholesale markets, specifically in ISO New England, New York Independent System Operator (NYISO), MISO, PJM, the Electric Reliability Council of Texas (ERCOT), and the California Independent System Operator (CAISO). Cheap natural gas, low power demand […]

In an effort to become a fully regulated power company, American Electric Power (AEP) has agreed to sell four Midwestern power plants—representing a total of 5.2 GW—to a newly formed joint venture of Blackstone and ArcLight Capital Partners for about $2.17 billion.  AEP will sell: the 1,186-MW natural gas–fired Lawrenceburg Generating Station in Lawrenceburg, Ind. […]

Updates finalized by the Environmental Protection Agency (EPA) to its Cross-State Air Pollution Rule (CSAPR) identify nitrogen oxide emission (NOx) reductions from power plants in 22 states to help states address transported pollution under the agency’s more stringent 2008 ozone air quality standards. It marks the first time the EPA has updated an existing program […]

If wind and solar photovoltaic (PV) penetrations in the Eastern Interconnection were amped up to 30%, they would decrease coal, combined cycle, and combustion turbine capacity factors by 30% to 50%, a new study from the National Renewable Energy Laboratory (NREL) suggests. The study, NREL’s Eastern Renewable Generation Integration Study (ERGIS), was released on August […]

Deciding to retire a coal-fired unit is often a tough call, but even tougher decisions follow. The next steps taken by a generation owner have multiple economic, environmental, and stakeholder consequences. Since 2000, U.S. generating companies (Gencos) have announced the closure of more than 200 coal-fired power plants, totaling 102 GW of generating capacity. Closures […]

The U.S. nuclear power business is in trouble, and Exelon has six units totaling more than 5,300 MW of dependable capacity on the chopping block. How will the Chicago electricity giant respond? Perhaps by acquiring more nuclear capacity? Chicago-based Exelon Corp., the largest nuclear power generator in the U.S., is facing what could be the […]

A fire at Muscatine (Iowa) Power and Water’s (MP&W’s) coal-fired power plant forced Unit 9 offline on August 30. The plant—located along the Mississippi River just south of town—includes three units with a combined capacity of about 276 MW. Units 7 and 8 were reportedly unaffected and continue to be available for power production. Customers […]

NRG Energy will pay $1 million in penalties, install environmental projects worth another $1 million, and complete costly upgrades under a consent decree it entered into with the state of Maryland to resolve wastewater discharge violations at two coal-fired power plants owned by its subsidiary GenOn.
