Owner/operator: NTPC Ltd. India’s state-owned generator NTPC operates a large fleet of power plants across the nation, and one of its top performers is found outside the capital of New Delhi. Staff at NTPC Dadri have taken a proactive, innovative approach to maintaining their plant, making it one of the most efficient in India despite […]

Owner/operator: Malakoff Corp. Bhd. Building a power plant on a site previously used for an aquaculture farm comes with more than a few challenges. For the Tanjung Bin Energy Power Plant, that meant some redesign and rework was required. Even so, the GE-led construction consortium made adjustments and delivered the state-of-the-art ultrasupercritical project on time […]

While it’s true that coal ash can be an environmental hazard if it’s not properly managed, there are a lot of positive uses for coal combustion products that actually provide benefits to the world. Many beneficial uses have been around for decades, but valuable new options are being developed, and some are starting to make […]

Like so many other power plant functions these days, regulatory and standards compliance can be automated. Know what you want an automated system to do before you make a vendor decision. As North American Electric Reliability Corp. (NERC) Critical Infrastructure Protection (CIP) enforcement deadlines and audit dates loom—notably, CIP-003-6 in April 2017, which addresses the […]

High-speed turbine rotor balancing was once rare because of the costs and logistical challenges involved in doing it during an outage. That’s begun to change as economic options emerge, and experience is showing that high-speed balancing can pay big dividends in reliability and maintenance costs. To a maintenance engineer or fleet manager, unwanted vibration in […]

In a widely expected move, the Japanese government finally killed the ill-fated Monju breeder reactor project on September 21, but reasserted its faith in breeder reactor technology as a component of the nation’s future power mix. The Monju plant was an ambitious project that never came close to meeting its backers’ expectations. Launched in 1980, […]

Global resources of variable renewable energy—primarily wind and solar—despite breakneck growth over the past two decades, are beginning to run up against technological and policy limitations on further deployment, and future growth will depend on significant changes in policy and grid design, according to a new report. Released on September 20, Variable Renewable Energy Sources […]

The $23.8 billion Hinkley Point C nuclear project has received the UK government’s green light, but the country wants to ensure that project’s ownership cannot change without government agreement. After a “comprehensive review” of the project and a revised agreement with French power generator EDF, the UK Department for Business, Energy, and Industrial (DBEI) Strategy […]

After years of incremental advances, a variety of innovations both simple and exotic are promising to boost the output of solar photovoltaic (PV) systems as much as 30% over current technologies—if the market can be convinced to adopt them. The Dawn of SiC For a generation, silicon has been the go-to material for semiconductor substrates. […]

A strategy rolled out by the Department of Energy (DOE) and Department of the Interior (DOI) to enable 86 GW of offshore wind capacity in the U.S. by 2050 highlights a number of key hurdles, including those related to technology, regulations, the environment, and markets. The DOE’s and DOI’s September 9–released joint document, “National Offshore […]
