Reliability performance is core to the utility industry. Utilities strategically design and invest in their system to maximize reliability performance—traditionally measured by System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), and/or Consumer Average Interruption Duration Index (CAIDI). These quantitative metrics largely drive utility investment decisions, shape strategic priorities, dictate regulatory approvals, […]

At the virtual 2nd Global Ministerial Conference on System Integration of Renewables on Oct. 27, several high-ranking policymakers pointed to a number of localized challenges affecting their countries’

The equipment and facilities supporting today’s critical infrastructure are vital to modern society. This article provides testing and maintenance tips to ensure systems are kept in top condition. Power

Distributed energy resources (DERs) are physical and virtual assets that are deployed across the power distribution grid. They are typically close to load, and though they initially began as behind-the-meter assets, today may be as likely to be deployed in front of the meter. DERs include renewable energy, and are the key component in microgrids, […]

The U.S. power industry lacks forward-looking ways to measure grid resiliency and traditional reliability metrics could become irrelevant as more intermittent generation inundates the bulk power system. But rather than continually looking backward to learn from ever-increasing emergencies or close-shaves, power system operators must work to cultivate a balanced portfolio that considers all aspects of […]

Microgrids offer an “all of the above” approach to distributed generation, incorporating a variety of technologies into their design. As microgrids continue to evolve, incorporating renewable power resources, fuel cells, battery energy storage, diesel and gas generator sets, microturbines, and other technologies, they also provide the opportunity to expand the business models for power producers. […]

In the competitive power market that exists today, utilities must utilize data to optimize their assets. With proper analysis, individual units, as well as fleets of plants, can balance operating costs

After Superstorm Sandy pummeled the great State of New Jersey in 2012, more than two million households were without power, many for close to two weeks. A silver lining is that this disaster occurred in the fall, after the heat of summer and before the onset of freezing conditions. With Sandy, New Jersey and the […]

It’s hurricane season in the U.S., which runs from June 1 through the end of November, and there have already been three named storms. The most recent was Tropical Storm Christobal, which was the earliest third-named Atlantic storm on record when it formed on June 2. It made landfall in the U.S. along the northern […]

Despite uncertainties posed by the COVID-19 pandemic, the Electric Reliability Council of Texas (ERCOT) again expects to shatter its peak demand record this summer. Factoring in changes to its generation profile, extreme weather, and low wind output, the grid operator expects energy alerts are still possible.  ERCOT’s forward-looking projections for capacity, demand, and reserves are murkier, […]

Federal regulators with oversight over U.S. power matters have issued a series of actions over recent weeks to respond to the potentially devastating impact that COVID-19, the new coronavirus, could have on North American power workforce operations and reliability. POWER will update this post regularly with COVID-19 response news and documents from federal and state […]

Hydropower delivers a range of benefits to society and the environment. However, there are two major challenges that face hydroelectric power plant operators—efficient use of water and high availability. To

While it is currently highly dependent on natural gas generation today, about 95% of ISO-New England’s (ISO-NE’s) interconnection request queue—a proposed total capacity of 20.9 GW—comprises wind, solar, and battery projects. That clearly indicates that developers in New England’s wholesale market “are looking to take advantage of state incentives, declining technology costs, and revenues from […]

Responding to a request from a Democrat-led U.S. House committee, the federal International Trade Commission (ITC) is investigating how New England’s increasing renewable targets are economically affecting the region, and what role renewable imports play in meeting those commitments. The ITC, an independent, nonpartisan and quasi-judicial federal agency that also provides fact-finding as it relates […]

Germany’s federal cabinet on Jan. 29 approved a nationwide phaseout of coal power generation by 2038, paving the way for the country, which has already initiated a nuclear phaseout, to rely even more heavily on renewables. The federal cabinet’s approval of the “Reduction and Termination of Coal Power Generation” (Gesetz zur Reduzierung und zur Beendigung der […]

The Federal Energy Regulatory Commission (FERC) on Jan. 23 approved two new reliability standards related to transmission system planning performance and cybersecurity. However, it also proposed to retire 74 reliability standard requirements, which it deemed duplicative or unnecessarily burdensome. Among the spate of actions it took on Thursday, FERC also green-lighted retaining the North American […]

Significant and rapid changes that are reshaping North America’s power sector will likely leave Texas and Ontario, Canada, with supply shortfalls over the next decade, and energy deficiencies could also occur during off-peak conditions in the Midcontinent Independent System Operator (MISO) area and the Western Electricity Coordinating Council (WECC) region, the North American Electric Reliability […]

Twenty-three projects chosen by the Department of Energy (DOE) in response to its 2019 Grid Modernization Lab Call provide a broad look at the critical issues that are roiling the nation’s power sector, as well as the tools and technologies that it has determined will best bolster the grid of the future in the near […]

It’s been a summer of power outages as extreme weather has been wreaking havoc on the electrical grid. Violent thunderstorms, tornadoes, and record-high temperatures have all taken turns knocking out the power across the East, from Michigan and Wisconsin to Washington, D.C. The lights even went out in Times Square and Manhattan’s West Side due […]

Authorities have initiated a far-reaching investigation into an unprecedented blackout that on June 16 hit a wide swath of South America—most of Argentina and Uruguay, and parts of Paraguay—affecting tens of millions of people.  The massive blackout—apagón—is thought to have originated in a disturbance that affected two high-voltage lines, Colonia Elia Y Mercedes and Colonia […]

The Electric Reliability Council of Texas (ERCOT) has issued a fresh warning that continued “above-normal” growth in electric demand could require it to enter Energy Emergency Alert (EEA) status to maintain system reliability this summer.  As it released its final Seasonal Assessment of Resource Adequacy (SARA) for the upcoming summer season (June to September), a preliminary […]

In an apparent attempt to show supporters he is making good on his pledge to revive the dying coal industry, President Trump has been trying to find a way to funnel tens of billions of dollars to a small

When conversations around the power industry turn to computer hacking, more often than not experts say it’s not a question of if, but rather, how systems have been compromised. William Doering, adjunct professor in the online Master’s in Business Administration program at Maryville University and a director with Guidehouse—a management consulting services provider—said he has participated […]
