  • Virtual Power Plants Are Becoming a Core Grid Resource—Not Just a Side Project

    For years, virtual power plants (VPPs) were treated by much of the power industry as a promising but niche experiment. A way to aggregate a modest pool of rooftop solar and residential resources and call it a grid resource. That framing no longer holds. In 2025 and through 2026, VPPs have moved much further into […]

To help […]

  • Solar, Storage, and the Day the Grid Goes Dark

    U.S. electricity customers averaged 11 hours of power interruptions in 2024, and major events accounted for 80% of that time, according to the U.S. Energy Information Administration. In recent years, Hurricane Helene left South Carolina residents without power for nearly 53 hours; in August of this year, Gary, Indiana, residents went nearly two weeks without […]

  • When Commercial Demand Takes the Lead: Rethinking Grid Planning for a New Load Era

    For decades, electric utilities have planned around a relatively predictable relationship between population growth, economic activity, weather and electricity consumption. Demand increased gradually, infrastructure investments followed long-term forecasts and utilities generally had time to prepare for changes in where and how electricity was consumed. That planning model is being tested. The U.S. Energy Information Administration […]

    Failure rates have plunged even as installed capacity soars, but a fire that refuses to end at Moss Landing shows how much depends on design vintage, operating limits, and the equipment around the cells. At about 6 a.m. on Sept. 18, 2026, workers at the Moss Landing Power Plant in California spotted a flare-up along […]

  • Reconductoring and Pipeline Integrity: Planning for the Shared Transmission Corridor

    Some of the most valuable real estate in the U.S. energy system is hidden in plain sight: the utility corridor. These narrow strips of land carry high-voltage alternating current (HVAC) transmission lines across farmland, suburbs, and industrial parks. They have become increasingly important as it becomes harder to add lines to new land. Building transmission […]

  • Grid Resilience Is About More Than Adding Capacity

    How much more generation will the U.S. need to meet rising electricity demand? It’s an important question, but it isn’t the only one the power industry needs to answer. As data centers, advanced manufacturing, and broader electrification increase demand, the growing challenge is delivering power where and when it is needed. COMMENTARY New generation can […]

  • Why DERs Are Necessary to Support the Power Grid

    A famous aphorism goes like this: “Doing the same thing over and over, and expecting a different result, is one definition of insanity.” In the world of electricity transmission, there is a direct corollary: adding more capital expense to a system that is already inherently broken doesn’t improve it or make it more reliable. That’s […]

  • Executive Order 14421: Managing the Risk of a Ban on Chinese Grid Equipment

    The nation’s electric grid depends heavily on foreign-made equipment, much of it from China. Depending on how the Dept. of Energy (DOE) chooses to implement Executive Order 14421 through its pending rulemaking for national security purposes, it has the potential to prohibit fully any Chinese-made equipment on the transmission grid. COMMENTARY The significance of Executive […]

  • Keeping the Lights on When Power Demand Fluctuates

    Data centers do what any industry would to continue operations during a power outage: Quickly pivot to their own emergency energy. As reported in several media outlets, a 10-minute grid outage in late July of this year on the East Coast caused data centers to hop off the main grid and switch over to their […]

  • Exelon Executive Sees Potential Return to Regulated Generation to Meet Soaring Demand

    Four years after separating from Constellation Energy, Exelon is expanding its transmission business and pressing for a greater role in power generation. Executive Vice President Carim Khouzami explains why rising data center demand, tightening capacity reserves, and shortcomings in PJM’s wholesale markets are changing the utility company’s strategy. When Exelon completed its separation from Constellation […]

  • Maintaining Uninterrupted Operations Amid Persistent Drastic Weather Conditions

    Severe weather conditions have become constant. Cyclones, storms, heatwaves, floods, and droughts continue to put critical infrastructure, homes, livelihoods, and lives at risk in the U.S. and around the world. Heat waves and droughts are the second-deadliest weather category, causing critical infrastructure instability, power line inefficiency, thermal sagging, and overloaded transformers that can lead to […]

  • How Advanced Nuclear Can Expand Utility Options

    Over 2,060 gigawatts. That is the staggering volume of generation and storage capacity currently trapped waiting in U.S. interconnection queues. According to data from RMI, the typical project now takes almost five years—stuck in administrative and transmission review before a single watt can be delivered to the grid. In 2008, it was only two years. For […]

  • The Blackout Behind the Blackout: What Sarnia’s 2003 Outages Reveal About Restart Risk

    Restoring customer supply is not the same event as restoring a process plant. Sarnia’s 2003 outages show why power-system resilience has to be carried through safe shutdown, utilities, environmental controls, and staged restart. The Grid Event Was Only the First Failure State At 4:11 p.m. on Aug. 14, 2003, the Northeast blackout began to pull […]

  • The Grid Reliability Risk Hiding on High-Voltage Insulation

    A high-voltage insulator can look unchanged for years while its operating environment steadily alters the conditions on its surface. Salt carried inland from a coast, industrial residue, road dust, moisture, ultraviolet radiation, and repeated weather cycles create an exposure history that can influence electrical performance and maintenance demands long before an asset reaches a predetermined […]

  • Keeping the Lights On — Smarter Fault Management for Data Center Power Systems

      Data centers commonly deploy looped medium-voltage (MV) distribution systems with automated protection and control schemes to deliver exceptionally high levels of power availability. However, these automation schemes rely on communications infrastructures where latency and scalability can affect fault-response performance. This paper presents a robust, hybrid FLISR strategy that integrates centralized and decentralized control to […]

  • The Grid’s Wasted-Power Problem Has a Sector-Coupling Fix

    For most of the last century, electricity and heat have been planned and regulated as two separate systems, a design choice that made sense when both were produced by burning fuel on demand. However, that design is a poor match for how the grid actually runs today. Generation, transmission constraints, and price all shift by […]

  • A Phased Framework for Adaptive Protection Migration in DER-Heavy Transmission Substations

    This article presents a practical four-phase engineering methodology for migrating legacy transmission substations toward adaptive protection architectures in power systems with high distributed energy resource (DER) penetration. Increasing DER integration introduces significant challenges to conventional protection schemes, including bidirectional power flow, dynamic fault current behavior, relay coordination complexity, and reduced protection reliability in aging substations.
