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 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 […]

According to the International Energy Agency (IEA), global power production from combined-heat-and-power (CHP) technologies has stagnated since 2000, lagging far behind growth in conventional power technologies and commercial heat generation. Despite having an average efficiency of 59%, CHP’s share of global generation in 2013 stood at just 9% (Figure 1), the bulk of it at […]

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, […]

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 […]

The U.S. market for electricity is trifurcated. More than half the country is served by competitive generators bidding against each other in wholesale markets. Almost half is served by conventional state-regulated, vertically integrated utilities controlling generation and transmission. The rest, a much smaller portion, consists of government-owned and customer-owned utilities, some of which are generators […]

The owner of a merchant 1,022-MW combined cycle natural gas–fired power plant in California has filed for bankruptcy protection, citing regulatory policies and market forces that have depressed revenues. La Paloma Generating Co. on December 6 filed for U.S. Chapter 11 bankruptcy, blaming a debt of $524 million that it racked up even though its four-unit […]

Ontario—Canada’s most populous province and its major economic engine—has an electric power supply system so driven by provincial politics that it has pushed the province’s utility generating arm, Ontario Power Generation, into what appear to be incoherent resource policies. Late last September, in a stunning announcement, the Canadian province of Ontario’s Energy Ministry said it […]
