Seven Software Tools for Energy Managers

There are many tools available to assist companies as they gain a better grasp on how their energy is being used, and what that means for the goal of efficient energy management. Not all solutions are created

Overcoming IIoT, Edge Networking Challenges

As power plants and substations become more connected, the need for rugged networking equipment built to withstand tough conditions is amplified. The military has already gone through the growing pains, so

A major demonstration. The team of SwRI, GTI, and GE Global Research will design, build, and operate a 10-MWe pilot plant for demonstrating supercritical carbon dioxide (sCO2) power cycles. The plant, shown here in an engineering concept drawing, will be located at SwRI’s headquarters in San Antonio. Courtesy: Southwest Research Institute

Game-Changing Supercritical CO2 Cycles Are Closer to Commercialization

Supercritical carbon dioxide (sCO2) cycles—which are inching closer to commercial applications for waste heat recovery, concentrating solar power, nuclear, and fossil energy—offer higher thermal efficiencies and power density than conventional steam Rankine and Air Brayton cycles in use today for power generation. But to realize these potentially game-changing cycles, common challenges associated with turbomachinery must […]

Utilities Prepare for Simulated Attack on U.S. Power Grid

Utilities across the country are gearing up for an attack on the power grid November 15 and 16. Thankfully, it’s only a drill. But in the event of an actual emergency, a real physical and cyberattack on the U.S. electricity infrastructure, GridEx IV—a biennial exercise conducted by the North American Electric Reliability Corp. (NERC)—will help […]

New Options in Industrial CHP Boost Efficiency and Returns

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 […]


TOP PLANT: Palm Beach Renewable Energy Facility 2, West Palm Beach, Florida

Owner/operator: Solid Waste Authority of Palm Beach County/Babcock & Wilcox Co. Although waste-to-energy (WTE) technology is well proven, the relatively low cost of landfilling garbage in the U.S. has foiled new power plant construction for many years. However, a facility in Florida—the first greenfield WTE project the U.S. has seen in 20 years—shows it’s still […]


Interest Builds for DONG Energy’s Bioresource Power Technology

Danish firm DONG Energy has begun building one of the world’s first bioresource power plants that will produce electricity from household waste by using enzymes to convert the waste to biogas. The commercial 5-MW plant under construction in the UK city of Northwich could be commissioned in early 2017. It will use the company’s proprietary […]
