All power plant equipment has a limited lifetime, but not all components age at the same rate. Some equipment may outlast the useful life of a plant, while other machinery may be replaced more than once

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

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

The James M. Barry Electric Generating Plant, both a coal-fired and natural gas-fired facility in Bucks, Alabama, sits on the west bank of the Mobile River. The facility’s coal is delivered via the river

Unmanned aerial systems—drones—have quickly found their place in the power sector. But as the industry moves out of test cases and experiments, and into full implementation of drones, it is facing a whole

From deregulation and restructuring to new technology and globalization, the power industry has undergone dramatic changes over the past few decades. Falling barriers to entry have led to the rise of small and independent power producers, and empowered consumers with choices when it comes to where to purchase their energy. These changes have transformed a […]

Thermal insulation is installed on almost every piping system and much of the plant equipment at power generation facilities. It not only saves energy, but also protects workers, reduces noise, helps protect against freezing, and more. This quiz is designed to test your knowledge of insulation fundamentals. Create your own user feedback survey If you’d […]

It’s become a cliché that government would be better if it were only run by private-sector managers using standard business practices. However, there are significant differences between the private sector and government. This quiz is designed to test your knowledge of those differences. Create your own user feedback survey To learn 18 more differences, read “25 Differences Between […]

GE Power said its 9HA.02 gas turbine reached a new milestone by exceeding 64% efficiency in combined cycle power plants. The company attributes at least part of the achievement to advances in additive manufacturing (3-D printing). “The HA is our most advanced gas turbine technology, and we’ve never stopped pushing the boundaries of what it […]

Fuel, operations, and plant design all affect the overall efficiency of a plant. This quiz is designed to test your knowledge of heat rate and efficiency fundamentals. Create your own user feedback survey To learn more about coal plant efficiency, frequent problems that reduce efficiency, and some solutions for improving operation and reducing generation costs, read “Understanding Coal […]

Power plants are inherently dangerous. Although safety is taken very seriously at most facilities, every year workers around the world are killed on the job by electrocution, falls, explosions, fires, and

Keeping combustion turbines spinning at power plants across Xcel Energy’s service territory is critical to maintaining reliability and minimizing costs. One of the challenges to meeting that goal is

Centrifugal pumps are one of the most popular types of pumps used both domestically and in industrial settings. There are various designs of centrifugal pumps (Figure 3), and they all work in a similar manner

The Electric Power Research Institute’s full spectrum of online monitoring-related research offers nuclear power plant operators guidance for monitoring program implementation. The research results are used

Power plants have been blowing soot using essentially the same method for decades. However, technological advances now offer boiler operators a much-improved technique. Rather than running sootblowing systems

Associated Electric Cooperative has spent a decade building a pulverizer performance program for its Thomas Hill Energy Center. The effort, combined with a sharp focus on maintaining proper air/fuel ratios

Originally embedded in the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code , today the Operation and Maintenance of Nuclear Power Plants standard for inservice testing of pumps

High-Pressure, Rotary Gear Pumps for Severe Applications  Northern Pump manufactures high-pressure, heavy-duty, positive-displacement, rotary gear pumps for industry, designed to perform in severe

GE and Exelon announced a multi-year agreement to deploy GE’s portfolio of Predix software solutions across the energy company’s six electric utilities to further enhance reliability and efficient service to its more than 10 million customers. Exelon’s six utilities will use these advanced analytics to further strengthen transmission and delivery systems. POWER Executive Editor Aaron […]

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 […]

Predictive analytics software offers many benefits when appropriately selected. However, finding the best solution for a given situation can be tricky. The tips provided here could help power companies avoid

It was less than a decade ago that the power industry was enthusiastic about the new Duplex Stainless 2205 Alloy being used in the construction of wet flue gas desulfurization (FGD) vessels. The alloy appeared

As the sole nuclear generator in the hydro-rich Pacific Northwest region, the Columbia Generating Station’s mission to provide safe, reliable, cost-effective, and carbon-free power has never been more

Power plants are designed to operate at their highest efficiency. Once a plant goes into operation, however, real life takes over and sometimes design outcomes are not regularly realized. Improving plant

J-seals are an integral part of efficient steam turbine operation. The failure of a J-seal can cause significant damage to the turbine rotor as material migrates downstream. For that reason, plant staff should

Recently, two epic hurricanes—Harvey and Irma—struck North America with extremely destructive force. Harvey first made landfall in the U.S. near Rockport, Texas, about 30 miles northeast of Corpus Christi

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a unique large-scale power converter that can swiftly switch between multiple energy sources to help

If recurrent problems are occurring at your plant, it could be an organizational issue rather than an equipment design deficiency. There are a number of reasons that root causes are overlooked. Understanding

Marmaduke Surfaceblow was a crusty character, providing POWER magazine readers with imaginative tales of engineering feats, and lending his name to one of our most-coveted awards. He might be fictional, but Marmaduke Surfaceblow became synonymous with POWER magazine, a colorful character with a distinctive way of finding solutions to engineering problems. Author Stephen Elonka introduced […]

Most large power plants have continuous vibration monitoring systems installed on turbine generators and other critical equipment. The systems have evolved greatly since the 1970s.
