Our electric system was designed to experience service interruptions once per decade. That time is long gone. In the past three years, the U.S. South has sustained two debilitating winter storms, forcing utilities to cut power when their customers needed it the most. In 2023 alone, the U.S. was hit with more than 28 separate […]

Prices at PJM Interconnection’s 2025/2026 base residual auction (BRA) spiked to $269.92/MW-day for most resources in the wholesale power market, pointing to a tightening supply-demand balance that could have significant implications for the regional transmission organization (RTO). The 2025/2026 BRA—a competitive capacity auction that procures power supply resources in advance of the delivery year to […]

More than two dozen states and a handful of trade groups filed separate lawsuits in the U.S. Court of Appeals for the D.C. Circuit, challenging parts of the Environmental Protection Agency’s (EPA’s) suite of new final environmental regulations targeting fossil-fired power plants. The challenges respond to the publication in the Federal Register on May 9 […]

In a time where capacity revenues are pricing lower and many generation owners find that their facilities are not being dispatched for energy on a consistent basis, reliable revenue streams are increasingly important. In addition to selling energy and capacity, many generation facilities collect fixed, monthly payments for the provision of “reactive power,” which are […]

Grid operators across the U.S. report they are largely prepared for the total solar eclipse that will pass over a large swath of North America on April 8, though they remain vigilant, monitoring for any unexpected shifts in power generation or demand that could test the power system’s resilience. The much-anticipated solar eclipse will begin […]

The Federal Energy Regulatory Commission (FERC), in Docket No. ER24-99-000, recently approved a suite of tariff revisions submitted by PJM intended to “accommodate the energy transition while maintaining resource adequacy.” Although the reforms affect many aspects of PJM’s Reliability Pricing Model (RPM), this commentary highlights: The transition from capacity accreditation using Equivalent Demand Forced Outage […]

PJM has urged Talen Energy to delay its deactivation of two of four units at the 840-MW coal, oil, and gas–fired Herbert A. Wagner Generating Station in Maryland until transmission upgrades are put into service around 2028.

Washington, D.C. – In a recent letter to PJM Interconnection, America’s Power explained that near-term coal plant retirements could be three times greater than PJM anticipates in its recent white paper, thereby increasing the risk of electricity shortages.  The PJM paper examines the disconnect between increasing coal retirements, growing electricity demand, and the slow addition […]

An Arctic blast felt by a large portion of North America is causing reliability turmoil within some segments in its bulk power system, forcing reliability coordinators to declare emergencies, issue conservation warnings, or shed load. TVA, Grappling With Demand Surge, Resorted to Load Shed Temperatures averaging the single digits across the Tennessee Valley Authority (TVA) […]

Few observers outside the electric utility industry understand the U.S. power grid, often called the world’s largest machine. It’s three grids, actually—the Eastern Interconnect, the Western Interconnect, and the Texas Interconnect. Much of the Eastern and Western Interconnects are subdivided regionally into independent organizations—independent system operators (ISOs) or regional transmission operators (RTOs)—that monitor, coordinate, and […]

NEW YORK, New York (June 23, 2022) — LS Power today announced that it has reached an agreement with an affiliate of ArcLight Capital Partners, LLC to acquire the Rolling Hills natural gas-fired power plant in Wilkesville, Ohio. The 835-megawatt facility consists of five simple cycle “peaking” units located in the PJM Interconnection. The transaction is […]

As we commemorate another Earth Day this April, the challenges facing our energy systems and the environment seem more pressing than ever. Americans face continued economic uncertainty following the COVID-19

Texas-based CPS Energy, the largest municipally owned electric and natural gas company in the U.S., has entered into a 15-year commercial agreement to explore installing up to 15 MW of geomechanical pumped storage (GPS). The agreement will kick off with a pioneering 1-MW project that will pump water into drilled wells and store it under […]

The PJM Interconnection’s Minimum Offer Price Rule (MOPR) was introduced in 2006 as a floor to bar new generators from artificially depressing capacity auction clearing prices through below-cost bids.

Recent reports from groups analyzing U.S. power generation note how states near the nation’s largest shale plays are expected to bring significant new natural gas-fired generation online over the next few years, despite concerns about recent market volatility that sent gas prices to their highest levels in more than a decade. With a long-term outlook […]

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 […]

America’s energy system has entered a new era where companies are competing against one another to reduce greenhouse gas emissions. Customers—large and small—are concerned about climate change, forcing business models to adapt beyond keeping the lights on. Today, 75% of households in the U.S. are served by a utility with a carbon or emissions reduction goal—to […]

Large-scale battery power capacity in the U.S. surged 35% over 2020 to reach 1,650 MW, and according to the Energy Information Administration (EIA), utilities are planning to ramp up that capacity by 10 GW over the next two years. In a newly released report, Battery Storage in the United States: An Update on Market Trends, […]

NRG Energy Inc. said it will retire three coal-fired power plants—two in Illinois and one in Delaware—next year after disappointing results in the May 2021 capacity auction for the PJM Interconnection. NRG during its June 17 investor day presentation said about 1.6 GW of coal-fired generation would be closed, including the 682-MW Waukegan and 510-MW […]

The past year and a half has been, to put it mildly, a weird time. Americans have grappled with the COVID-19 crisis, as well as with the associated economic fallout that revealed cracks in a number of our nation’s workforce and social systems. But recent years have also exposed the significant flaws in parts of […]

The U.S. Senate on Nov. 30 confirmed Federal Energy Regulatory Commission (FERC) nominees Allison Clements and Mark Christie, filling out all five seats at the helm of the federal energy regulator with a bipartisan panel for the first time in nearly two years.  Clements, a Democrat, replaces former Commissioner Cheryl LaFleur for a term that […]

A quest for reliability and flexibility is driving significant interest in hybrid and co-located resources, but their widespread integration could hinge on how they are defined and valued in wholesale

The tension between state and federal lawmakers is ages old, with a history marked by periods of outright assault or relative peace. On Dec. 19, 2019, the quiet in the energy sector was broken by an order from

The Federal Energy Regulatory Commission (FERC) issued an order that advocates for distributed energy resources (DERs) say will enable DERs, including renewable energy such as solar, wind, and battery storage, to compete on a more-level playing field in the organized capacity, energy, and ancillary services markets run by regional grid operators. FERC Order No. 2222, […]

The Federal Energy Regulatory Commission’s (FERC’s) ruling on Sept. 4, 2020,  rejected, in a three-to-one decision, the New York Independent System Operator’s (NYISO) proposal to change its capacity market rules, ostensibly intended to support, among other things, New York and New Jersey’s ambitious, and some say, unattainable renewable goals. The action comes directly on the […]

New Jersey on Sept. 9 opened a second state offshore wind solicitation that could triple its committed capacity from 1.1 GW to 3.5 GW. The state this week also laid out a final strategy for how it will achieve its November 2019–expanded offshore wind target of 7.5 GW by 2035.  New Jersey’s five-member Board of […]

Three major gas-fired power projects—a total of 2.1 GW—in Eastern competitive markets that are slated to come online between 2023 and 2025 have chosen hydrogen pathways to ensure their long-term viability as states increasingly emphasize energy system decarbonization.  The plants, which represent a total investment of $3 billion, will adopt integrated green hydrogen solution packages […]

It’s an article of faith in large parts of the U.S.—at least among power industry people—that organized and Federal Energy Regulatory Commission (FERC)–regulated “merchant” interstate power markets are the best way to ensure a sufficient supply of electricity, as well as to ensure fair and equitable prices for ratepayers. On that basis, large areas of […]

Four U.S. nuclear generators—Energy Harbor, Xcel Energy, Exelon, and Arizona Public Service (APS)—are making headway on projects to demonstrate hydrogen production at nuclear plants, but scaling those efforts up to net new end-users and sources of revenue is still ridden with hurdles, company officials said in a panel discussion at the American Nuclear Society’s (ANS’s) […]
