Two nuclear plants owned by Exelon Corp. in Illinois and Pennsylvania failed to clear PJM Interconnection’s latest annual capacity auction, putting one of those financially crippled units at risk of early retirement. Meanwhile, procurements for solar, wind, and demand response fell dramatically compared to last year, and drastic price declines could roil the market for […]

President Donald Trump wants to balance the federal budget in 10 years, and it appears he believes that to do so, deep cuts to the nation’s energy research funding are needed. The administration’s fiscal year 2018 (FY18) budget request, released Tuesday, May 23, cuts funding for the Department of Energy (DOE) by $1.7 billion, a […]

Freshly reeling from a statewide blackout, South Australia’s government in March released an energy plan that seeks to cut its reliance on an electricity interconnector with eastern Australia that feeds the

Grid-connected batteries have long been touted as a tantalizing prospect that could help balance electricity supply and demand as the amount of installed variable renewable generation ramps up. New

New York’s electricity system and markets face a blizzard of changes, driven by policy, politics, and economic forces. The New York Independent System Operator and the New York State Energy Research and

A flood of renewable capacity in the European Union is forcing member countries to consider grid upgrades that offer a more substantial power supply management role to distribution system operators. Lee

Rain and snow has returned to California, ending the record-setting drought with record-setting precipitation. The drought led to forest fires, dead orchards, and brown lawns. It also took a big bite out of ratepayers’ wallets and increased global warming emissions, due to the loss of low-cost, zero-emission hydropower. In a study released April 26 by […]

Natural gas supply and price, along with lower electric demand and the growth of renewables, have been far more responsible for the decline in the U.S. coal industry than environmental regulations, according to a new study by Columbia University’s Center on Global Energy Policy and the Rhodium Group, a New York consulting firm. That means […]

The U.S. Energy Information Administration (EIA) expects natural gas–fueled electricity generation will exceed all other fuel sources once again this summer, marking the third year in a row that gas has been the leader. However, the EIA anticipates electricity generation from both gas and coal will be less this summer than in 2016. The reason […]

An April 6–issued report released by the World Energy Council suggests that the single biggest worry among global energy leaders is commodity price volatility. Prices appear to be a big concern because of the “Grand Energy Transition” toward de-carbonization. Leaders in resource-holding countries, such as Saudi Arabia, are anxious about long-term economic models, if prices […]

Global new renewable power capacity grew in 2016 even as global new investment in renewables dropped, according to a report commissioned by the United Nations Environment Program out April 6. The Global Trends in Renewable Energy Investment 2017 report found that global investment in renewables—excluding large hydro—fell in 2016 by 23% to $241.6 billion. That […]

Russia Marks Milestone with Commercial Operation of Third-Generation Reactor. After nearly a decade of construction, the first advanced third-generation VVER-1200 nuclear reactor began commercial operation on

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

New technology is being used throughout the power industry to improve plant efficiency, predict trouble with degrading equipment, forecast weather trends, and train workers. A recent conference hosted by POWER

Technology advancements and new regulatory requirements could reshape how power plant owners operate and maintain large power transformers. Experts outline emerging strategies and call attention to overlooked

The U.S. should capitalize on China’s formidable experience to put its own domestic solar power sector on a more “economically sensible” path, researchers from Stanford University said in a new report. The March 21–released report, “The New Solar System,” which was funded by a research grant from the U.S. Department of Energy (DOE), offers a […]

The Trump administration released a blueprint of its proposed 2018 budget on March 16, likely setting off a major battle with Congress. The budget proposal, “America First: A Budget Blueprint to Make America Great Again” makes major cuts in non-defense discretionary spending over 2017. While funding for the Department of Defense is boosted $52.3 billion, […]

Regardless of recent federal support for a revitalization of coal in the U.S., “the economics are challenged,” Lynn Good, CEO of Duke Energy, said March 1 during a presentation at the U.S. Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) Energy Innovation Summit. “I think coal continues to be an important part of a […]

Bipartisan lawmakers in Minnesota want utilities in that state to procure 50% of power sold by 2030 from renewable sources. The measure, if passed, could put the state’s renewable efforts on par with California’s. The bipartisan bill introduced in the Minnesota Legislature on February 27 seeks to double the state’s renewable energy standard, which is […]

A bill signed by Minnesota’s Gov. Mark Dayton (D) on February 28 allows Xcel Energy to build a 786-MW combined cycle gas-fired power plant without approval from state regulators. The governor signed Chapter 5, House File 113, a bill that had bipartisan support of the state’s legislators, to allow the Minneapolis-based power company to move […]

The Edward Hyatt hydroelectric plant at the damaged Oroville Dam in northern California, shut down earlier this month after its spillway nearly collapsed, may reopen soon, officials with the California Department of Water Resources (DWR) said on March 1. The plant was forced to shut down after severe erosion from the dam’s spillway deposited large […]

Siemens has installed the prototype of its towering 8-MW offshore direct-drive wind turbine at a national test center in Østerild, Denmark, marking the company’s foray into the global race to develop mega–wind turbines. The new offshore turbine was installed on a steel tower at a hub height of 120 meters (m) in late January (Figure […]

A long-term energy strategy unveiled by leaders of the United Arab Emirates (UAE) in early January suggests that the federation on the Arabian Peninsula will increasingly rely on renewables to power its soaring economic growth. The UAE’s energy strategy was unveiled by Vice President Sheikh Mohammed bin Rashid Al Maktoum, who is prime minister of […]

The boom in renewable energy, spurred by dramatically falling costs, has led some experts and political figures to begin talking seriously about what was once science fiction: A world powered entirely by renewable generation. But is it truly feasible or economic? One series of studies suggests it is—with some important caveats. In the first half […]

A variety of approaches have been used to capture new benefits from combined heat and power (CHP) facilities. Some owners have transitioned to new fuels or added renewables to the mix, while others have implemented unique business models to spur development. As district heating systems are brought into the 21st century, the CHP sector seems […]

A wastewater treatment plant in the Danish city of Aarhus is reportedly producing enough power to cover all of the energy used for the whole water cycle in its catchment area—from water production and water

Solar roadways—roads that incorporate embedded photovoltaic cells—have piqued interest for several years. A few examples are finally being rolled out, though their practical applications are still being evaluated. On December 20, global transport infrastructure group Colas completed installing a solar panel paving system it calls “Wattway” (Figure 5) over 50 square meters (m2) at the […]

Combined heat and power (CHP) has long been a popular option for industrial self-generation, but new technologies and business partnerships are taking the sector well beyond the traditional boilers and diesel gensets. The Erving Paper Mill in the western Massachusetts town of the same name has operated for more than 100 years. Once part of […]
