The Electric Power Research Institute (EPRI) has launched an ambitious new initiative alongside power companies, grid operators, and several tech giants to establish five to 10 “flexibility hubs” that will demonstrate how data centers can be leveraged as flexible grid resources starting in the first half of 2025. EPRI’s three-year Data Center Flexible Load Initiative […]

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. The nation’s largest regional transmission organization (RTO) on Jan. 10 said it informed Talen that the deactivation of […]

A new natural gas-fired power plant has entered commercial operation in Ohio. The 1,875-MW Guernsey Power Station, in Guernsey County in southeastern Ohio, is sourcing gas from the Marcellus and Utica shale plays, two of the most-prolific natural gas production areas in the U.S. GE Vernova’s Gas Power division on June 7 said the plant […]

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 […]
