Distributed Energy

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

The Hawaiian Electric Co. (HECO) and technology service company Stem Inc. have successfully tested nearly 1 MW of energy storage systems at 29 commercial sites on Oahu, the companies said on January 30. The novel pilot project, which sought “the ability to connect many customers’ energy storage with the utility,” comprises an energy storage “fleet” […]

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 […]

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 […]

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 […]

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, […]

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 […]

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.
