The Tennessee Valley Authority (TVA) has reached another milestone in its effort to bring Watts Bar Unit 2 into commercial operation: The unit completed its final power ascension test—a 50% load rejection from full power—and safely returned to full power on September 30. The testing had been halted on August 30 due to a switchyard […]

 
 
 
How does this investment compare to the alternative (buying a new turbine)?
Updating a control system is inexpensive compared to buying a new turbine.  Although new turbines offer higher heat rates, better emissions and overall more MW output than older systems.  The Return on Investment of a new turbine would take more years to recover. 

According to the International Atomic Energy Agency (IAEA), there are 60 nuclear reactors currently under construction around the world. China leads the way with 20 units in progress, followed by Russia with seven, and India with five. Twelve other countries, including the U.S., round out the list. The IAEA predicts that nuclear power generating capacity […]

The Mátra Power Plant in Visonta, Hungary, uses a dense slurry system for handling fly ash and other coal combustion residuals. The DSS combines ash and water in a 1:1 ratio, creating a cement-like slurry.

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 […]

When a gas turbine goes down, recovery can be an expensive, time-consuming process. Knowing what can go wrong and how to anticipate turbine failures can help you avoid a difficult unplanned outage. Gas-fired power is hot and getting hotter. The Energy Information Administration estimates that 2016 will be the first year ever that the U.S. […]

For all its record-breaking achievements for speed, innovation, and efficiency, the 3,960-MW Sasan Ultra Mega Power Project should have been a POWER Top Plant. But the unique project has been plagued by serious setbacks—including loss of life—that show how perilous the plant construction journey can be. A decade ago, India was suffering a power crisis […]

For all the words published over the past several years about electric utility customer defection—thanks to the combination of lower-cost residential solar photovoltaic systems, tax incentives, and net
