Begun with grand ambitions in the early 1980s, the second unit at Argentina’s Atucha site ran smack into the country’s economic crises in the following decade. But a determined crew brought the project to completion after a 13-year hiatus through a focus on rebuilding the nation’s nuclear labor force. As with many other nations in […]

The nearly 4-GW, three-unit Palo Verde Nuclear Generating Station remains the largest generator of electricity in the U.S. for the 23rd consecutive year, producing more than 30 million MWh in 2014, for the 10th time (the only plant in the U.S. to do so), all while using only treated wastewater for cooling. Palo Verde Nuclear […]

Some critters may be cute, but when jellyfish gum up power plant cooling systems; birds, rats, snakes, or squirrels cause electrical shorts; or invasive mollusk species obstruct hydropower plant pipes, losses can be steep. Here’s how some power plant operators are dealing with their critter troubles. There are countless cases of wildlife entering power plant […]

As many coal-fired power plants designed for baseload service are asked to cycle, unforeseen stresses have been introduced to boiler pressure parts. Understanding the effects and implementing mitigation strategies could prevent premature component failure and keep facilities operating reliably. On August 3, 2015, the U.S. Environmental Protection Agency finalized the Clean Power Plan, which calls […]

Creeped out and fatigued—that’s the state of many coal-fired boilers these days. Understanding failure mechanisms and suitable testing methods for identifying potential trouble can help you find problems before the problems find you. Even as the current regulatory environment pushes new power generation to utilize natural gas over other fuel sources, a significant amount of […]

Coal dust combustion events injured employees and damaged equipment at Laramie River Station in May 2013. Any dust-filled facility could consider implementing some of the plant’s corrective actions to reduce the risk of experiencing a similar incident. When Laramie River Station (LRS), near Wheatland, Wyo., was built nearly 35 years ago, it was state-of-the-art. Constructed […]

Largely dependent on imported fuel oil, many island systems must grapple with soaring electricity costs and reliability issues, in part because they are isolated and they don’t benefit from economies of scale. But some nations are seeking alternatives. It’s the same story all over the world. To fuel their economies and support growing populations, geographically […]

As the coal industry declines in many places around the world, can the mines it leaves behind be repurposed for cleaner energy projects that benefit multiple stakeholders, including local economies? Several existing and planned projects demonstrate that there may be multiple paths toward that transition. No question, the coal industry in Appalachia, the rest of […]

Generation III nuclear reactors have not shown much ability to overcome the weaknesses of conventional Gen-II light-water reactor technology, offering at best evolutionary approaches. Is there room for a more revolutionary approach? Many parties are exploring new technologies, but it’s impossible to tell which, if any, will succeed. Last August, Andy Revkin, The New York […]

Once again, a first-of-a-kind technology at a coal-fired power plant that is designed to reduce its greenhouse gas footprint has run into design, operational, and cost problems. This time, it’s Saskatchewan, Canada utility SaskPower’s Boundary Dam Carbon Capture project that’s facing scrutiny. (Earlier this week, an overdue precombustion carbon capture project, Mississippi Power’s Kemper County […]
