Battery energy storage has exploded in deployment over the past several years, but the majority of it by capacity, especially in North America, is deployed at grid scale. That may be a problem, because a new study from the Rocky Mountain Institute (RMI) suggests the greatest value to the system lies with behind-the-meter batteries—distributing battery […]

ABB in August commissioned the world’s first high- and medium-voltage gas-insulated switchgear (GIS) bays that use a new “eco-efficient” gas mixture instead of sulfur hexafluoride, the greenhouse gas that is typically used. The 170/24-kV switchgear bays were supplied to Swiss utility ewz for a new 3 x 50-megavolt-ampere substation (Figure 5) in Zurich, Switzerland, which […]

The societal impact of a “Black Sky Day”—a term used by electric infrastructure security experts when discussing a collapse of the North American power grid—would be devastating, according to Dr. Daniel Baker, distinguished professor of Planetary and Space Physics at the University of Colorado, Boulder. Baker testified before two subcommittees of the U.S. House of […]

Broad, bipartisan energy legislation that would allocate federal funding to grid technology research and demonstration along with a number of other initiatives, including cybersecurity and the energy-water nexus, has cleared the Senate Energy and Natural Resources Committee with an 18–4 vote.  The committee’s chair, Sen. Lisa Murkowski (R-Alaska), and Ranking Member Sen. Maria Cantwell (D-Wash.) […]

When a large electromagnetic pulse (EMP) or geomagnetic disturbance (GMD) event occurs—which, according to Sen. Ron Johnson (R-Wis.), there is “100% certainty” will happen at some time in the future—as many as 9 out of 10 people in the U.S. could die. Johnson, chairman of the U.S. Senate Committee on Homeland Security & Governmental Affairs, […]

Five of Germany’s largest lignite power plants will be mothballed to allow the country that is already phasing out nuclear power to meet ambitious climate goals by 2020.  In what it called a “milestone decision,” the government on July 2 agreed to scrap plans to impose a controversial—and by some accounts, illegal—climate tax for conventional […]

A new report from the Government Accountability Office (GAO) reveals surprising aspects about how federal subsidies for electricity have been distributed, how the power generation mix has shifted, and how consumption has transformed since 2001.  The June 29–released report, “Generation Mix has Shifted, and Growth in Consumption has Slowed, Affecting System Operations and Prices,” responds […]

Wind is no longer a niche alternative energy industry, American Wind Energy Association (AWEA) CEO Tom Kiernan told attendees at WINDPOWER 2015.  Despite policy hurdles, the wind sector has seen exponential growth and formidable cost reductions; it has the government’s endorsement for a low-carbon future; and it’s making up an ever-larger share of the nation’s […]

In contrast to the bitter partisanship that has paralyzed Congress for the past few years—especially with respect to energy policy—the Obama administration’s first Quadrennial Energy Review (QER) received a mostly warm welcome from House GOP members, who echoed its concerns with the state of the nation’s energy infrastructure during a hearing on June 2. “Many […]

The Obama administration’s first installment in the Quadrennial Energy Review (QER) drew a variety of responses in its first public hearing before the Senate Energy and Natural Resources Committee on April 28. Chairman Lisa A. Murkowski (R-Alaska) opened the hearing with a nod to the still-in-limbo Keystone XL pipeline. She noted that though the QER […]
