When it comes to running a power plant, it’s easy to take the little things for granted. Yet it’s the little things that often have the greatest impact on plant managers’ ability to deliver reliable service for their customers. Take power, for instance. Plant managers are focused on bringing power to their customers. But are […]

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 […]

In recent years, coal power generators have faced increasing difficulty predicting annual fuel requirements due to more cycling and low-load operation. That presents problems for the people negotiating fuel contracts. Not all mining companies are amenable to contract changes, but some unique solutions have been developed. Remember when coal-fired power plants supplied baseload power 24/7/365 […]

Uranium oxide, the basic fuel for nuclear power plants, has recently sold at prices not seen in the past 13 years. In fact, the price is less than the cost of production in many cases. That could be a problem, because little is being done to increase the fuel supply, even though the world is […]

As concerns about grid security increase globally, it’s a good time to review the history, scope, and effect of North American electric system reliability standards. As the threat landscape changes, standards alone are not enough. Mandatory. That’s the key word in the Energy Policy Act of 2005 (EPAct) where grid security is concerned. Within two […]

Canada Inches Closer to Nationwide Carbon Price. Canada’s government in early December struck a deal with eight of the country’s 10 provinces to introduce its first national carbon price. The government has proposed that carbon would cost C$10 per metric ton in 2018, rising by C$10 a year until it reaches C$50 in 2022. Only […]

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 […]

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 […]

A draft national electricity plan published in December by India’s Central Electricity Authority (CEA)—a statutory organization that is overseen by the Ministry of Power—looks to add 101,645 MW of new conventional capacity during the current 12th Five-Year Plan (2012–2017), nearly 85% of which will be coal-fired. But after that, through 2022, the country will refrain […]

Pipes, valves, turbines, pumps, condensers, and other mechanical components in the radiologically controlled area (RCA, or hot side) of a nuclear power generation facility require routine inspection, testing, maintenance, and, eventually, replacement or repair.
