• Texas Energy Regulators, Gas Industry Try to Reassure the Public That the State’s Power Grid Is Ready for Winter

    As state regulators and the companies that power the grid take steps to avoid another catastrophe like February’s winter storm, climate experts say this winter will likely be milder.

  • Balance of Power—Building a Resilient Electric Grid

    Events such as blackouts and outages are increasing in frequency as the nation’s infrastructure ages and climate change leads to extreme weather events. Hotter, wetter summers and harsher winters require more reliance on heating and cooling utilities, placing higher stress on the nation’s electric grid. Newtechnology can ‘help keep the lights on’ during emergencies.

  • Microgrids May Hold the Key to Grid Resilience

    The aging energy grid is being pushed to the breaking point. Power outages from extreme weather alone cost anywhere from $2 billion to $77 billion per year. And some isolated communities still rely on diesel generators for electricity, since powerlines don’t reach them. Grid expansion isn’t an option—in most cases, the economics don’t make sense. When the main grid falls short, the right mix of renewables offers local, low-carbon power.

  • “People Should Probably Be Worried”: Texas Hasn’t Done Enough to Prevent Another Winter Blackout, Experts Say

    Natural gas powers the majority of electricity in Texas, especially during winter. Some power companies say the state’s gas system is not ready for another deep freeze.

  • Big Batteries on Wheels: Zero-Emissions Rail While Securing the Grid

    Trains have been on the sidelines of electrification efforts for a long time in the U.S. because they account for only 2 percent of transportation sector emissions, but diesel freight trains emit 35 million metric tons of carbon dioxide annually and produce air pollution that leads to $6.5 billion in health costs, resulting in an estimated 1,000 premature deaths each year. Researchers show how battery-electric trains can deliver environmental benefits, cost-savings, and resilience to the U.S.

  • Providing Resilient Power

    Extreme-weather events and wildfires can put power grids under pressure and threaten their ability to produce reliable power. A microgrid demonstration project demonstrates DC microgrid technology for resilient power to homes and installations.

  • Utilizing Demand Flexibility in Electricity Distribution Networks

    The transition to sustainable energy sources like wind and solar and the introduction of electric vehicles and heat pumps are putting a growing strain on our electricity distribution networks.

  • Important Breakthrough to Help Secure Electrical Grid

    As the electrical grid is modernized, it requires new safeguards to keep it safe from cyberattackers. Researchers have developed a novel security approach to find and stop cyberthreats that penetrate the IT layer, preserving grid stability.

  • Long Power Outages After Disasters Aren’t Inevitable – but to Avoid Them, Utilities Need to Think Differently

    Americans are becoming painfully aware that U.S. energy grids are vulnerable to extreme weather events. Hurricanes in the east, wildfires in the west, ice storms, floods and even landslides can trigger widespread power shortages. And climate change is likely making many of these extreme events more frequent, more severe or both.

  • Restoring Power During Severe Storms

    Recovery, guided by common policies from FEMA and industry, varies with respect to the severity of disruptive events. The failures under study were induced by a wide range of disruptive events from hurricanes, nor’easters, and thunder and winter storms from 2011-2019, affecting nearly 12 million people.

  • Metallic Balloon Causes Massive Blackout in Dresden, Germany

    More than 300,000 buildings and apartments in Dresden, Germany, were without electricity on Monday after a metal-coated party balloon caused a major short circuit at the city’s main power station. The police is investigation whether this was an accident or a deliberate sabotage. Balloons have caused power disruptions in Germany in the past: the most notable cases are Stuttgart in 2017 and Frankfurt in 2015.

  • Can Burying Power Lines Protect Storm-Wracked Electric Grids? Not Always

    Electricity is critical for health, safety and comfort. People wonder whether their electricity service might be more secure if those lines were buried underground. But I’ve studied this question for utilities and regulators, and the answer is not straightforward. There are many ways to make power grids more resilient, but they are all costly, require the involvement of many agencies, businesses and power customers, and may not solve the problem.

  • Planning for the Future in a Changing Climate

    How can companies, for example, utilities, know how changes in climate will impact their assets and their business strategy? And what can they do to identify and address issues before they affect customers? A partnership between the largest state public power entity in the U.S., the New York Power Authority (NYPA), and Argonne National Laboratory will enable the utility to better assess how its assets and business may be affected by extreme weather and other hazards.

  • Detecting, Blocking Grid Cyberattacks

    Researchers have designed and demonstrated a technology that can block cyberattacks from impacting the nation’s electric power grid.

  • Wildfires Threaten California’s Power Grid

    Wildfires blazed through California, Arizona, and Oregon, driven by winds and a lack of humidity.. Death Valley in California’s Mohave Desert hit 128 degrees Fahrenheit. Utility officials in Oregon were keeping a weary eye on the Bootleg Fire which is raging out of control in southern Oregon and threatening Path 66 — a vital electric line corridor linking California with the Oregon power grid. The blaze in Oregon threatens the power lines which carry power to California.
