Cheap natural gas and social pressure to reduce carbon emissions give gas-fired power plants and renewable energy resources a competitive advantage over traditional coal and nuclear generation. Energy storage

NV Energy plans to retire a 254-MW coal-fired unit in a power-constrained region of Nevada at the end of 2021, four years ahead of schedule. The company will instead purchase 1,001 MW from new solar photovoltaic projects equipped with 100 MW of long-term battery storage, effectively doubling its total renewable generation from 14% in 2017 […]

The accelerated retirement of coal-fired and nuclear generation by 2022 could adversely affect reliability in four regions, including in the East and over parts of the central U.S., the North American Electric Reliability Corp. (NERC) warned as it released findings from a “stress-test” scenario.  But the entity tasked with ensuring reliability and security of the […]

Despite increased resilience actions, extreme weather events due to climate change are projected to increasingly threaten the nation’s energy infrastructure, and create fuel availability and demand imbalances, the Trump administration’s sprawling climate report released on November 23 suggests.  The Fourth National Climate Assessment (NCA4) released by the Global Change Research Program (USGCRP) is clear in […]

The Tennessee Valley Authority (TVA) wants public input as it considers closing two of the utility’s historic coal-fired power plants: its Bull Run plant in Tennessee, and the last coal-fired unit at its Paradise plant in Kentucky. The Bull Run Fossil Plant, near Oak Ridge, has been the only single-generator coal plant in the TVA […]

To remain efficient and profitable, utilities must anticipate the ebb and flow of the market. That means companies must gain visibility into the generation and consumption of energy. With network-level

Coal-fired power plants can significantly improve wet limestone scrubbing with advanced process control. One optimization system implemented at a Japanese facility utilized enhanced regulatory control

The Jackson Hole Center for Global Affairs—a bipartisan think tank—will host the “Jackson Hole Global Forum: Climate Solutions, Coal Communities, and Economic Diversification,” in Jackson Hole, Wyoming, November 8–9, 2018. Among the sessions on day one is a panel titled “What Is Coal’s Future?” Charles K. Ebinger, nonresident senior fellow with the Atlantic Council, will […]

A subsidiary of grid operator PJM Interconnection has joined with a Switzerland-based group to build and evaluate a blockchain-based tool to help the U.S. power generation industry. Energy Web Foundation (EWF) and PJM Environmental Information Services (PJM-EIS) on October 25 said they would collaborate on developing and testing a reference implementation of EWF’s open-source Energy […]

Utilities are faced with many disruptive changes in the power market. Customers are demanding cleaner energy and turning to distributed generation as a solution. One expert suggested power companies must react and evolve their business models to change with the times. During a keynote presentation at the Distributed Energy Conference in Golden, Colorado, on October […]

Packing 150 mph winds, Hurricane Michael has made landfall along the Florida Panhandle. The almost–Category 5 storm might well be the strongest to hit the Emerald Coast in more than 100 years. Not since Hurricane Opal, back in 1995, has there been a storm even remotely as strong as Michael to strike the coastal area. Causing major havoc […]

At the end of July, India’s Central Electricity Authority (CEA) noted in its annual load generation balance report (LGBR) for the year 2018–2019 that the country will likely have a peak surplus of 2.5% and

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what affects

The California Independent System Operator’s Energy Imbalance Market (EIM) is a real-time energy market, the first of its kind in the western U.S. EIM’s advanced market systems automatically find low-cost

At this moment, the lights are on around the country in homes and workplaces.  Most don’t realize, perhaps take it for granted, that those lights come on because of the hard work of dispatchers operating one of the most important manmade systems ever built, the national electric power grid. Without oversimplifying the process too much, […]

Unlike their regulated counterparts, merchant power generators have increasingly struggled to compete over the last few years and the outlook for many is that this won’t change any time soon. While regulated power companies often enjoy near monopolies in their respective markets, merchant power companies build out their power generating capacity on a speculative basis […]

Driven by increased energy efficiency and the relocation of electricity-intensive industries, electricity demand and consumption has steadily declined in many developed markets during the last decade, according to the International Energy Agency (IEA). Yet middle- and working-class households, as well as small businesses, are spending more of their income on electricity than their parents’ generation. […]

It is safe to say that all electricity customers want reliable and resilient power service. One way that some end-users are ensuring they get it is by investing in distributed energy resources and building microgrids. But rather than simply using these systems as emergency backups, more and more owners are finding ways to capture economic […]

Düsseldorf, September 3, 2018 – GEA supplies Saint-Gobain with two Waste Heat Recovery Systems (WHRS) each for the utilisation of waste heat from the float glass production lines in Pisa, Italy and Sriperumbudur, India. Commissioning is planned for the first half of 2019. GEA technology makes it possible to generate electricity and compressed air from […]

The U.S. power system is separated into three major components—the Western Interconnection, the Eastern Interconnection, and the Electric Reliability Council of Texas. The three operate almost independently

Electric vehicles (EVs) have the potential to realign the transportation sector and present an opportunity for the power industry to transform and reinvent itself in fundamental ways. But whether this

The inaugural integrated system plan (ISP) released by Australia’s Energy Market Operator (AEMO) in mid-July warns that the country is in the midst of a “transformative and unprecedented” rate of change

The Frades II pumped-storage hydro project in Portugal took advantage of existing dams to incorporate a scheme that includes the largest variable-speed reversible units installed in Europe. The facility

Do you drive an electric vehicle (EV)? If you answered yes and live in the U.S., you’re among the roughly 1% of drivers doing so in this country. If not, how soon do you think it will be before you become
