A three-judge panel for the D.C. Circuit on April 18 unanimously upheld Order No. 1000, denying multiple challenges by New England power firms and state regulators to the Federal Energy Regulatory Commission’s (FERC’s) controversial mandate that requires utilities to remove certain “right of first refusal” provisions from existing tariffs and agreements. The decision in Emera […]

Two years after the Energy Union was launched as a strategy to help the European Union (EU) provide secure, sustainable, competitive, and affordable energy, the 28-member bloc is seeing a precipitous drop in

A power plant’s isolated phase bus is generally reliable, and therefore, maintenance is frequently overlooked. However, the system is too important to neglect. Assessing its condition during minor outages

There have been numerous pronouncements recently about the upcoming demise of the bulk power grid as consumers are projected to move toward decentralized green energy sources. We don’t believe that the end

Remote and online monitoring of plant performance parameters is an important step toward a fully connected plant, but alone it’s not enough to exploit the real value in the Industrial Internet of Things, speakers at POWER’s inaugural Connected Plant Conference on February 15 in Dallas said. Randy Bickford, president and CTO of software firm Expert […]

The U.S. may be getting its first overhead 600-kV high-voltage direct-current (HVDC) line in more than 20 years. Developers are advancing the Plains and Eastern Clean Line, a 720-mile (1,150-kilometer [km]) project that could deliver 4 GW of renewable power from the Oklahoma Panhandle region to states in the Southeast. The project is spearheaded by […]

The entire state of South Australia suffered a blackout on the afternoon of September 28. The cause of the event has been disputed, but it has left Australians in a raging debate about the state of the country’s electricity system and policies that will shape its future power mix. The so-called “Black System” event that […]

As energy storage becomes more ubiquitous and projects grow in size and capacity, utilities of all types are exploring the best ways of putting it to use across the grid. The opportunities are large, but so are the challenges, according to a panel of executives who spoke at Energy Storage North America in October. New […]

“We’re at a very challenging time,” said former Federal Energy Regulatory Commission (FERC) Commissioner Tony Clark at the annual meeting of the National Association of Regulatory Utility Commissioners (NARUC) on November 14. We have a “need for infrastructure, but it’s more difficult to get it sited and built than ever before.” Clark’s comment, which he […]

The Federal Energy Regulatory Commission (FERC) last week unanimously adopted a final rule on reliability standards to address the threat to the grid from geomagnetic disturbances (GMD).

Global resources of variable renewable energy—primarily wind and solar—despite breakneck growth over the past two decades, are beginning to run up against technological and policy limitations on further deployment, and future growth will depend on significant changes in policy and grid design, according to a new report.
