coal retirements

Louisville Gas and Electric Co. and Kentucky Utilities Co. (LG&E and KU) will replace two aging coal generation units at Mill Creek Generating Station in Kentucky—a combined 600 MW—with a 645-MW GE Vernova hydrogen-ready 7HA.03 gas turbine. GE Vernova announced the order for the heavy-duty gas turbine—the most advanced of its HA-class models—from the two […]

The Tennessee Valley Authority (TVA) has moved to retire its iconic 1.3-GW Kingston Fossil Plant in Tennessee in 2027 and replace it—with notable urgency—with a 1.5-GW modern complex featuring a combined cycle gas turbine (CCGT) plant, aero-derivative turbines, 100 MW of battery storage, and up to 4 MW of solar generation. The nation’s largest public […]

A landmark project to test fuel blends of up to 25% volume of hydrogen mixed with natural gas in reciprocating internal combustion engines (RICEs) has launched at WEC Energy Group’s 56-MW A.J. Mihm power plant in Michigan. If successful, the pilot—one of the first of its kind in the U.S.—could provide key insight into how […]

Michigan’s largest energy provider Consumers Energy will stop using coal as a fuel source for power generation within the next four years—15 years earlier than previously planned. In an updated integrated resource plan (IRP) filed with the Michigan Public Service Commission (MPSC) on June 23, the CMS Energy subsidiary said the effort would lead Michigan’s […]

American Electric Power (AEP) will shut down or refuel 5.6 GW of its 2020 coal-fired power fleet by 2030 to comply with environmental rules—including recent revisions governing federal coal ash and effluent limitations—and rebalance its portfolio in a bid to meet ambitious climate goals.  The move is bold for the Columbus, Ohio-based generating giant, which […]

Falling natural gas prices tamped down annual U.S. wholesale power prices over the last decade by $7/MWh to $53/MWh—to a much higher degree compared to the impact of wind and solar growth—a new report from Lawrence Berkeley National Lab (LBNL) suggests.  The Nov. 20–published report, The Impact of Wind, Solar, and Other Factors on Wholesale Power […]

DTE Energy has announced a goal to achieve net-zero carbon emissions by 2050, following steps by Duke Energy, American Electric Power, and NRG Energy to do the same over the past two weeks. The Detroit-based company on Sept. 26 said it would go beyond its existing commitment to reduce carbon emissions 50% by 2030 and […]

Chile, a country that relied on coal for about two-fifths of its power generation in 2016, in June announced it would mothball eight coal plants, totaling 23 GW, of its existing 28-plant coal fleet over the

The U.S. is investing heavily to ensure its future coal-fired power fleet will be cleaner, more efficient, and more flexible, experts said at the 9th International Conference on Clean Coal Technologies in Houston on June 4. The conference—which is taking place this week in the U.S. for the first time—is spearheaded by the IEA Clean […]

A report from an independent market monitor for PJM Interconnection shows that natural gas-fired power generation topped coal-fired output in PJM in 2018, the first time that gas has topped coal in the history of the largest U.S. grid operator. The “2018 State of the Market” report from Monitoring Analytics LLC, which includes Volume 1 […]

Industry aggressively fought the Mercury and Air Toxics Standards (MATS) when the Obama administration proposed it in 2011 and finalized it in February 2012, warning it would precipitate the closure of a swathe of coal capacity nationwide. Six years later, the rule appears to have had a sizable impact on the power sector, but not […]

Vistra Energy moved to halt a financial hemorrhage stemming from unprofitable conditions in the Electric Reliability Council of Texas (ERCOT), announcing plans to shutter two more coal-fired power plants—the 1.1-GW Sandow Power Plant (which includes a 2009-built unit) and the 1.2-GW Big Brown plant—in early 2018. The company’s decision made public on October 13 comes on […]

A week after the Department of Energy (DOE) proposed a rule to bolster uneconomic coal and nuclear generators in competitive power markets, Luminant announced that an “unprecedented low power price environment” will force it to retire a 1.9-GW coal-fired power plant operating in the Texas market. The plant’s economic woes suggest a larger swath of […]

Several factors favor natural gas when it comes to the future of U.S. power generation. But other forces, such as power demand, energy efficiency, and the impact of renewables, make it a complex fray. Let’s

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 […]

Denmark’s DONG Energy is the latest in a string of power companies that are shunning the use of coal in future generation fleets. The company said on February 8 it will stop burning coal completely by 2023 in its power stations, replacing it with sustainable biomass. The measure is part of a company-wide transformation towards […]

Even if the final Clean Power Plan is not implemented, U.S. electricity-related carbon dioxide (CO2) emissions will remain well below 2005 levels, the Energy Information Administration (EIA) said in a comparison of two cases looking forward through 2040. The cases are part of the agency’s May 17–released Annual Energy Outlook 2016 Early Release (AEO2016 Early […]

As it promised last May, Michigan-based Consumers Energy is shuttering seven of its oldest coal-fired plants, which make up more than two-thirds of its coal fleet. Consumers Energy made the decision last year in response to changing environmental regulations and market conditions that made it uneconomic to continue operating the plants. The seven units, all […]

Of nearly 18 GW of U.S. generating capacity permanently shuttered in 2015, 77% was conventional steam coal–fired. About 30% of that 13.7 GW in coal capacity was retired in April 2015, when the Environmental Protection Agency’s (EPA’s) Mercury and Air Toxics Standards (MATS) rule went into effect, said the Energy Information Administration (EIA) on March […]

In a Monday morning session at the annual meeting in Austin of the National Association of Regulatory Utility Commissioners (NARUC), panelists and commissioners traded comments on challenges and successes related to integrating increasing levels of renewables while ensuring reliable grid operation. David Boyd, VP of government and regulatory affairs for the Midcontinent Independent System Operator […]

The Clean Power Plan could force the retirement of up to 4 GW of coal-fired capacity in the region served by the Electric Reliability Council of Texas (ERCOT) starting as soon as 2022, an updated analysis suggests.  The independent system operator that manages about 90% of Texas’ electric load acknowledged that fewer coal units are […]

Interstate Power and Light (IPL) will be forced to spend $620 million to retire 10 coal-fired units and retire, refuel, or install pollution controls at several others in Iowa under a settlement reached with the federal government.  The Alliant Energy subsidiary has long anticipated the settlement announced on July 15 by the Environmental Protection Agency […]

The Environmental Protection Agency’s (EPA’s) Clean Power Plan will certainly be challenged in court, but states and power companies must expend enormous resources developing and complying with state plans regardless of the outcome, witnesses testified on March 17 at a House hearing on the proposal’s legal and cost issues.  The three-hour-long hearing at the House […]

The Obama administration’s Clean Power Plan could result in the retirement of between 3.3 GW and 8.7 GW of coal-fired capacity in the Electric Reliability Council of Texas (ERCOT) grid and jeopardize electric reliability for the state that is already power strapped, the independent system operator (ISO) says in a new analysis.  The Environmental Protection Agency’s […]

NRG Energy is the latest company in a string of generators choosing to cease burning coal at generating units to comply with environmental rules.   An environmental action plan to reduce air pollution in Illinois released by the New Jersey–based company on Aug. 7 proposes to retire the 251-MW coal-fired Unit 3 at the 761-MW […]
