  • Nation’s Power Operators Warn Congress of a Coming Reliability Shortfall

    Seven major U.S. grid operators have raised a unified alarm about an impending capacity crunch, warning that the pace and scale of explosive demand—including from data centers, manufacturing, and electrification—pose a precarious misalignment with accelerating generator retirements and transmission constraints. At a March 25 hearing before the House Energy and Commerce Subcommittee on Energy, the […]

  • Building a Better Grid—Infrastructure Upgrades Require Ingenuity, Innovation, and Investment

    The need for more reliability and resilience of power delivery, both in the U.S. and worldwide, has utilities and grid operators looking for solutions to the challenge of bolstering the electricity supply. Electric grid infrastructure, both in the U.S. and other parts of the world, needs an upgrade. Increased power demand from energy-intensive industries such […]

  • Maine Lawmakers Back Transmission Project for Renewable Energy

    A project to build more than 100 miles of transmission lines, along with multiple substations, to enable the use of more renewable energy in Maine has received support from state lawmakers. LS Power Grid Maine, a subsidiary of New York-headquartered LS Power, on June 26 said the Aroostook Renewable Gateway effort has received the first […]

  • Vermont and ISO-New England Provide an Interesting Renewable Energy Transition Case Study

    Vermont doesn’t get a lot of attention outside of Bernie Sanders, but the state’s power system is worth taking a look at as it has undergone a notable shift toward renewable energy. About 80% of

  • ISO-NE Warns Fuel Supply Issues May Threaten Winter Power System Reliability

    New England faces a precarious fuel supply risk that could necessitate emergency actions if a severe prolonged cold snap hits the region this winter, ISO New England (ISO-NE) has warned.  The regional grid operator expects power demand will peak at 19,710 MW during average winter weather conditions of 10F, but if temperatures plunge below 5F, […]

  • ISO-NE Move Puts New Gas-Fired Plant in Doubt

    The future of a natural gas-fired power plant planned in northeastern Connecticut is in jeopardy after regional grid operator ISO-New England (ISO-NE) asked the Federal Energy Regulatory Commission (FERC) for permission to end a capacity contract with the project. Florida-based NTE Energy’s plan to build the 650-MW Killingly Energy Center has been delayed due to […]

  • Solar Drives Down Price for ISO-NE Power

    Silicon Valley-based SunPower on March 16 said it has secured grid capacity for about 11 MW of power after a winning bid in ISO New England’s 14th Forward Capacity Auction (FCA), in which companies predict the cost of making power in 2023. The auction, which closed in February, saw a record low price of $2 […]

  • ITC Probing Economic Impact of Renewable Goals, Imports to New England

    Responding to a request from a Democrat-led U.S. House committee, the federal International Trade Commission (ITC) is investigating how New England’s increasing renewable targets are economically affecting the region, and what role renewable imports play in meeting those commitments. The ITC, an independent, nonpartisan and quasi-judicial federal agency that also provides fact-finding as it relates […]

  • Plan to Build New 1-GW Plant in Rhode Island Officially Dead

    A project to build a 1-GW gas-fired power plant in Rhode Island has officially ended, after developer Invenergy took no action to appeal the project’s rejection by state regulators, who earlier this year voted unanimously against the plant’s construction. Invenergy had until Nov. 15 to challenge the formal denial of a construction license for the […]

  • States to FERC: Promote Market Designs That Recognize State Priorities 

    Attorneys general from 11 states ramped up pressure on the Federal Energy Regulatory Commission (FERC) to recognize state policy goals as it makes decisions related to market design, siting of new gas pipelines and storage facilities, and grid reliability.  The measure is the latest in a string of recent pushes by states to ensure federally […]

  • Rhode Island Rejects Burrillville Gas-Fired Plant

    A proposed 900-MW gas-fired power plant was rejected by Rhode Island regulators on June 20, leaving project developer Invenergy pondering its options for the planned facility in Burrillville. Rhode Island’s Energy Facility Siting Board, after a daylong hearing in Warwick, said the plant is not needed. Chicago, Illinois–based Invenergy can appeal the decision to the […]

  • Polar Vortex Tests Resiliency of U.S. Power System 

    Brutally cold temperatures in the midwestern and northeastern U.S. spurred grid operator alerts as natural gas demand has surged, power prices have soared, and there have been forced generator outages.  The polar vortex, an extreme cold event characterized by back-to-back cold fronts, has so far prompted states of emergency in Wisconsin, Illinois, and Michigan. On […]

  • FERC Thwarts ISO-NE’s Attempt to Keep Mystic Gas Units Online

    The Federal Energy Regulatory Commission (FERC) on July 2 denied ISO-New England’s (ISO-NE’s) request for a tariff waiver to keep two gas-fired units—a total capacity of 1,700 MW—at Exelon’s Mystic Generating Plant in Boston, Massachusetts, running to address “fuel security risks.” The commission instead gave the grid operator a year to submit permanent tariff revisions […]

  • Six Glaring Interventions in Competitive Markets — Beyond the Trump Plan

    The Trump administration’s attempt to prop up uneconomic “fuel secure” generators in competitive markets is just the latest in a string of recent “extra-market” interventions that experts said imperil independent organized markets for electricity. In a recent white paper, Raymond Gifford and Matthew Larson, energy partners at Wilkinson Barker Knauer LLP, said the restructured administrative […]

  • Concerns About Summer Reliability in Texas and California Persist

    Higher-than-average temperatures forecast for much of the U.S. this summer won’t affect reliability in most regions, though concerns remain for Texas and Southern California, according to the Federal Energy Regulatory Commission (FERC). Presenting the “Summer 2018 Energy Market and Reliability Assessment,” on May 17,  FERC staff said that most entities that are part of the […]

  • THE BIG PICTURE: A Cold Comparison

    The “bomb cyclone,” a winter storm that descended on much of the eastern U.S. from December 27, 2017, to January 8, 2018, renewed the raging debate about resiliency and prompted flashbacks of the “polar vortex,” a similar deep freeze that transpired in January 2014 and was compounded by the loss of 82 GW nationwide for various reasons. […]

  • U.S. Electric Markets in Transition

    The U.S. market for electricity is trifurcated. More than half the country is served by competitive generators bidding against each other in wholesale markets. Almost half is served by conventional state-regulated, vertically integrated utilities controlling generation and transmission. The rest, a much smaller portion, consists of government-owned and customer-owned utilities, some of which are generators […]
