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 […]

Yesterday’s retail tariff is prohibiting the optimal dispatch of cogeneration resources as our grid is transforming with high levels of solar generation and potential overgeneration issues. An Unintended Consequence of Policy California has some of the most ambitious energy efficiency and renewable energy goals in the world. Investments in renewable energy and other clean energy […]

Amazon’s latest wind farm in coastal North Carolina has completed construction and is weeks from beginning operations—and state legislators have just asked the incoming Trump administration to shut it down. The $400 million, 208-MW, 104-turbine project, built by Apex Renewables near Elizabeth City and backed by financing from Iberdrola Renewables, is supposed to power Amazon’s […]

For the third straight year, renewable generation accounted for the majority of new utility-scale capacity additions in the U.S. during 2016, the Energy Information Administration (EIA) said on January 10. The EIA estimated that the U.S. added 24 GW of new utility-scale generation in 2016, of which 63% was renewables, almost all of it wind […]

Beyond major reliability events that have prompted regional blackouts in the past, the U.S. grid faces “imminent danger from cyber attacks,” warns the second installation of the Obama administration’s Quadrennial Energy Review (QER). Here are other key trends outlined in the comprehensive study of the nation’s electricity system. The QER, available on the DOE web site, identifies the threats, […]

China rolled out its latest five-year energy development plan, detailing the country’s aim of investing about 2.5 trillion yuan (more than $363 billion) through 2020 in the development of renewable energy resources. Yang Li Zhe, deputy director of China’s National Energy Board, explained the country’s vision during a press conference held in Beijing on January […]

The Department of Energy (DOE) has dropped its support of a 24-MW offshore wind demonstration project proposed by Fishermen’s Energy off the coast of Atlantic City, N.J. “Under the Energy Department’s award, Fishermen’s Energy must have secured a power offtake agreement by December 31st to be eligible for another round of funding,” a DOE spokesperson […]

Just as the election of Donald J. Trump could result in redirected energy policy in the U.S., 2017 elections in France and Germany could reshape plans for electricity infrastructure on the European continent. Also on both continents, some factors and trends will be out of elected officials’ control. “Difficult to see. Always in motion is […]

A digital roundtable with four senior members of diverse generating companies reveals that regulations aren’t the top concern at the moment. Instead, decisions are being driven both by customer desires and

How do you get generating company executives and those who interact with the power industry to think outside the box when planning for the future? The answer may involve a board game. Humans are pre-programmed to prefer routine, tradition, and regularity, without questioning whether longevity equals good. Fear of the unknown, and the power of […]

Japanese Firms Poised to Build Two 540-MW IGCC Plants Based on Nakoso Technology. A consortium of Japanese firms on December 1 said they had received full-turnkey orders for two integrated gasification

As our January 2017 cover image of a dynamic Rubik’s Cube suggests, the power industry, especially in the U.S., is dealing with something akin to solving a 3-D puzzle whose pieces are being added and subtracted as the game is being played. Although shares of traditional, regulated electric utilities remain some of the most predictable […]

A tumultuous election year that was marked by market turmoil, the events of 2016 clearly showed that big change is afoot for the power sector. Many of POWER‘s bold predictions for 2016, such as that the near-simultaneous surge in U.S. natural gas production and recent enactment of environmental rules would reshape the U.S. power sector, […]

POWER‘s monthly infographic sheds light on power sector trends globally, and in 2016, it highlighted water issues, future coal fleet technologies, U.S. power plant retirements, energy storage technologies, China’s power glut, global emissions limits, and more. January 2016: Future Coal Fleet What the world’s future coal fleet will look like by technology. February 2016: GHG […]

Oregon State University’s Northwest National Marine Renewable Energy Center was awarded up to $40 million by the DOE to create a wave energy test facility in Newport.

The Federal Energy Regulatory Commission (FERC) on December 15 proposed reforms to its large generator (20 MW or more) interconnection processes. The notice of proposed rulemaking (or NOPR in FERC-speak) would revise FERC’s 2003 pro-forma large generator interconnection procedures and agreement. At the FERC meeting approving the proposed rule, FERC Chairman Norman Bay said, “Much […]

Although optimistic about the future of the coal industry under the Trump administration, Robert Murray, CEO of Murray Energy Corp., the largest underground coal mining company in the U.S., does not expect the president-elect to bring back coal mining jobs or spur new coal-fired power plant construction. “I’ve asked President-elect Trump to temper his comments […]

In a finding that is likely to boost controversy over the future of U.S. energy policy, a comprehensive study of the full levelized cost of energy (LCOE) from various sources of electricity conducted by the University of Texas (UT) at Austin’s Energy Institute found that wind turbines and natural gas combined cycle power plants (CCPPs) […]

Germany’s highest court ruled on November 6 that energy firms E.ON, RWE, and Vattenfall have a right to seek compensation as a result of the 2011 decision to prematurely shut down the country’s nuclear fleet.
