In a step that it hopes will be emulated by developers of new natural gas generation facilities in the U.S., NTE Energy has voluntarily committed to drastically slash greenhouse gas (GHG) emissions from the proposed 550-MW Killingly Energy Center facility in Connecticut—and to shut it down by 2050 unless it operates with no net GHG […]

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 […]

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. When technicians need to work at height, erecting a scaffold often provides the safest and most effective method of access. This […]

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 […]

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 […]

Complying with reliability standards requires considerable resource planning. The tools and suggestions provided here may help engineers conform to new generator relay loadability requirements. But compliance

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 […]
