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

California’s excess of solar power challenges the statewide independent system operator’s ability to balance its system without curtailing low-carbon supplies and ramping up natural gas generation. It’s

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. Released on September 20, Variable Renewable Energy Sources […]

A merger proposed between Canadian firm Enbridge and Houston-based Spectra Energy Corp. could create the largest energy infrastructure company in North America. The companies announced on September 6 that they have entered into a definitive agreement to combine in a stock-for-stock merger transaction that has an enterprise value of $127 billion. The transaction was reportedly […]

UK Abolishes Climate Change Department. As part of the major governmental shakeup triggered by Brexit—the UK’s momentous vote to leave the European Union—newly appointed UK Prime Minister Theresa May

Reliability and cybersecurity ranked as the two most important issues currently confronting the electric industry, according to surveys completed by 672 qualified utility, municipal, commercial, and community stakeholders for Black & Veatch’s “2016 Strategic Directions: Electric Industry Report.” It’s not particularly surprising to see reliability rank at the top of the list. “Reliability has always […]

The governments of Ireland and Northern Ireland have big ambitions for their unified electricity market, including a wind-heavy 40% renewable generation target by 2020. Making that happen while delivering safe, reliable electricity to customers across the island means a sea change in how the grid is operated. One of the first big steps is installation […]

Dutch power grid operator TenneT on June 10 unveiled plans for a large-scale island transmission hub in the North Sea that could connect numerous offshore wind farms and transmit their generated power to the Netherlands, the UK, Belgium, Norway, Germany, and Denmark via direct current (DC) cables. Those cables, or “spokes” could also serve as […]

A severe solar storm striking the continental U.S. could cause trillions of dollars in damage to the global economy and shut down portions of the U.S. grid for up to a year, according to a new study prepared by the Cambridge Centre for Risk Studies for insurance firm AIG. The study, Helios Solar Storm Scenario, […]

2016 EEI Edison Award winners are AEP and AES

The Department of Homeland Security (DHS) internally recognizes that a power grid failure resulting from an electromagnetic pulse (EMP) or a solar storm can pose great risk to the security of the nation, but it hasn’t prepared adequately, the Government Accountability Office (GAO) said in a newly released report. The GAO’s 68-page report, “Federal Agencies […]

It’s not being overly dramatic to say that the power industry is at its biggest inflection point to date. Even ignoring the effects of environmental regulations and (in North America, at least) cheap natural

What are distributed energy resources (DERs)? For many people, rooftop solar is the first thing that comes to mind, but when you ask that question of an independent system operator (ISO)—the folks who

Getting the most cost-effective use out of a battery storage system isn’t just a matter of plug-and-play. Where and how you site a battery can make a big difference in how well it does its job. Several battery experts who spoke to POWER explain what you need to think about. So you want to buy […]

Two senior power sector executives opened the 2016 ELECTRIC POWER Conference and Exhibition in New Orleans April 19 with a message that generators need to “think big” and embrace possibilities of disruptive technologies—or risk being run over on the road to the future. Leo Denault, chairman and CEO of Entergy Corp., delivered the opening keynote […]

Canadian utility Fortis wants to acquire ITC Holdings Corp., the largest independent electric transmission company in the U.S., to benefit from “low-risk” regulated power markets. The deal valued at about $11.3 billion will allow Fortis to enter the U.S. regulated power market overseen by the Federal Energy Regulatory Commission (FERC), providing a “unique, highly diversified, […]

Calpine Corp. will idle a 578-MW natural gas–fired combined cycle (CCGT) power plant in northern California for likely the remainder of the year. The Houston-headquartered company told POWER on January 15 that it will put the 2001-built Sutter Energy Center in Yuba City in “cold layup.” That means that while will the plant will not […]

A new grid modernization blueprint released by the Department of Energy (DOE) on January 14 seeks to integrate conventional and renewable power sources with energy storage and efficiency measures, while ensuring the grid is resilient against cyberattacks and climate change threats. The DOE said that the plan will help “frame new grid architecture design elements, […]
