The Nishi Nagoya power plant in Japan is more than just the showcase of a successful fuel-conversion project. It’s the holder of a world record, thanks to a GE Power gas turbine that again has set the global

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what affects

The Environmental Protection Agency’s (EPA’s) Affordable Clean Energy (ACE) rule is proposed to replace the 2015 Clean Power Plan—which the Supreme Court stayed in February 2016 and never went into effect. According to the EPA, the replacement is necessary because the Obama-era Clean Power Plan “exceeded the EPA’s authority.” However, like the Clean Power Plan, […]

Building power plants is only the first step to generating success. Running plants efficiently, and consistently improving efficiency as they run, is the path to putting profits on the bottom line. Building

Chubu Electric’s Nishi-Nagoya power plant Block-1 in Japan, a plant powered by three GE 7HA turbines and Toshiba Energy Systems & Solutions steam turbine and generator technology, is officially the world’s most efficient combined-cycle power plant, according to Guinness World Records.  The entity that collects and showcases ultimate record-breaking facts highlighted the plant’s achievement of […]

Power plants are designed to operate at their highest efficiency. However, once a plant goes into operation, real life takes over and design outcomes are not always realized, which can seriously hurt a plant’s profitability. That’s why improving plant performance and getting back to design conditions should be every operator’s objective. This quiz is designed to test […]

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 […]

Coal proponents and climate skeptics often cite China’s current and future reliance on coal power to bolster talking points. What is little discussed is the recent, massive transformation of China’s vast
