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 […]

South Africa’s state-owned utility faces recent generation shortages, plant construction problems, load shedding, and uncertainty at the African continent’s only nuclear power plant. And that’s just on the generation side. Moves on the business planning and regulatory side are painfully slow and could, some argue, be writing the utility’s obituary. Eskom, South Africa’s state-owned monopoly […]

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 […]

The second World Nuclear Exhibition was held at a moment in time when the prospects for nuclear power are both tantalizing and frustrating. One thing is clear: The dynamics of the nuclear power industry have changed recently—and so have the solutions proposed for achieving greater certainty. One of the strongest arguments nuclear power has going […]

As combined cycle gas turbine plants are called upon to play a larger and more flexible role in the generation mix, it’s important to schedule a comprehensive assessment of major components at key intervals to ensure reliable operation. Just like humans, power plants can benefit from regularly scheduled condition assessments, which are sometimes called “health […]

Deciding to retire a coal-fired unit is often a tough call, but even tougher decisions follow. The next steps taken by a generation owner have multiple economic, environmental, and stakeholder consequences. Since 2000, U.S. generating companies (Gencos) have announced the closure of more than 200 coal-fired power plants, totaling 102 GW of generating capacity. Closures […]

Inexpensive natural gas, increased renewable energy utilization, and ever-tightening environmental regulations have limited the use of waste feedstocks for power generation. But while often dismissed out of hand, with proper planning and understanding of the market, power producers can realize benefits from waste-to-energy projects. It was a tropically hot day at the plant, and it […]

The U.S. nuclear power business is in trouble, and Exelon has six units totaling more than 5,300 MW of dependable capacity on the chopping block. How will the Chicago electricity giant respond? Perhaps by acquiring more nuclear capacity? Chicago-based Exelon Corp., the largest nuclear power generator in the U.S., is facing what could be the […]
