Lake Kivu, the 1,040-square-mile “killer lake” that stretches over the border between Rwanda and the Democratic Republic of Congo (DRC), has long been a source of trepidation. Because it sits between two

Fortum Värme, a company jointly owned by Finnish energy firm Fortum and the city of Stockholm on May 9 inaugurated a new biomass-fired combined heat and power (CHP) plant on the shores of Värtan, a strait in Sweden’s capital city. The Värtan CHP8 (130 MWe, 280 MWth), which began construction in 2013, will begin commercial […]

Fuel cells are a rapidly expanding option for distributed generation, with fuel cell–based power plants now being deployed in capacities into tens of megawatts (see “59-MW Fuel Cell Park Opening Heralds

China’s CAP1400—a reactor design based on Westinghouse’s AP1000 pressurized water reactor—has successfully passed the International Atomic Energy Agency’s (IAEA’s) Generic Reactor Safety Review. The milestone is significant for China, which plans to deploy the advanced reactor design in large numbers (Figure 4) as well as export the technology. 4. On the nuclear horizon. An artist’s […]

Eskom operates 23 power stations in South Africa with a total capacity of more than 42 GW. It supplies about 95% of all the electricity used in the country. One of its coal-fired power stations was experiencing frequent boiler tube fatigue failures in the hopper section—the bottom part of the boiler—of all six units. The […]

Now that power plant operators have some experience under their belts related to Mercury and Air Toxics Standards (MATS) compliance, it’s time to reevaluate the options for demonstrating compliance. Starting

When gas-fired plants are required to cycle more than they were designed for, added stress on plant components isn’t the only consequence. You also need to pay closer attention to turbine catalyst systems. Traditionally, many combined cycle gas turbine (CCGT) power plant units were designed and permitted for a baseload or similar operating profile. Startups […]

When owners of the Big Stone Plant researched air quality control system technology, they considered all available options and eventually settled on a design that was not in widespread use. Now that the

Discussions about environmental issues related to power plants and the regulations governing their operation are as old as the industry, I discovered while thumbing through the bound July through December 1914 issues of POWER. The specifics of the environmental concerns have become more detailed and complex as scientific knowledge, monitoring technologies, and mitigation solutions advance. […]

As power plant reporting requirements for emissions regulations increase in number and complexity, yesterday’s data collection and reporting systems can make the job harder than it needs to be. The electrical power generation sector is reportedly the largest source of greenhouse gas emissions in the U.S. As such, it is the focus of the Environmental […]

Renewable generation is usually characterized as more environmentally friendly than fossil fuels, and in many respects, that’s true. But there is a growing recognition that solar and wind generation have their own impacts, and an increasing number of manufacturers and generators are looking for ways to minimize them. Iceland might be about the last place […]

Courtesy: Ad Meskens/Wikimedia Commons Europe has been in the forefront of renewable energy development, and though the scientific research on wildlife impacts is limited, European environmentalists and developers are beginning to create baseline frameworks and guidelines. Developers around the world can learn from their experience. As more renewable energy systems come online, providers hope to […]

Increased reliance on natural gas as a fuel for electric generation has prompted regulatory reforms by the Federal Energy Regulatory Commission (FERC) to improve coordination between the two industries. Many in the power industry believe critical constraints in gas pipeline infrastructure serving New England pose a significant threat to electric reliability and prices during periods […]

Rush Island Energy Center has successfully fired Powder River Basin (PRB) coal for two decades, as proven by the plant’s excellent performance stats, dedication to minimizing its environmental footprint, and sterling safety record. The PRB Coal Users’ Group top award recognizes the plant staff’s long-term dedication to continuously improving its safe handling and efficient combustion […]

It’s axiomatic that state governments believe they can manage their own affairs better than the federal government. But our system reserves certain bailiwicks for federal oversight, and one of those is the

Plans are under way to install a pilot 1-MWh lithium battery–based storage system in 2018 at the world’s first floating wind farm in Aberdeenshire, Scotland. The “Batwind” system, to be installed at

Human workers are imperfect, which is why there’s no magic bullet that will give you a safe workplace. But new research on human behavior and how that translates into safety attitudes is helping some in the power industry get beyond the traditional platitudes. Safety first. Safety is no accident. Be aware—Take care. Those and others […]

The Environmental Protection Agency’s rule to regulate the disposal of coal combustion residuals as solid waste went into effect last fall. After evaluating the available solutions and technologies, here’s what some experts consider the safest and most effective approaches for complying with the rule and protecting the environment. A little over a year ago, the […]

An industry rooted in tradition is facing unprecedented changes and challenges, and meeting them requires “thinking big” and embracing disruptive technologies that will change how we think about electricity generation and delivery. That was the message from the keynote session at ELECTRIC POWER 2016.  Two senior power sector executives opened the 2016 ELECTRIC POWER Conference […]

This year’s much-awaited Environmental Mega Session at the 18th annual ELECTRIC POWER Conference & Exhibition in New Orleans, La., on April 19 was titled “Navigating Clean Power Plan Compliance”

The annual panel discussion by high-level leaders from diverse power companies is a cornerstone of the ELECTRIC POWER Conference & Exhibition, and it has been consistently emblematic of the state of the

Power generators have always had to make afetyome changes as each new generation enters the sector, but today’s new workers are bringing with them attitudes and skills that challenge traditional plant management, for good and ill. Here’s what some companies and plants are doing to make the best use of younger workers while getting them […]

The nuclear industry has been expecting big things from small modular reactors (SMRs) for a long time, but to date, no SMRs have reached commercial construction phase. That may change soon. Utah Associated Municipal Power Systems has a plan to deploy NuScale Power’s Integral Pressurized Water Reactor at a site in Idaho. Will others follow […]

China unveiled its 13th Five-Year Plan this March. The official proposal that will guide the country’s economic and social development from 2016 through 2020 lays out targets and other measures to address a number of climate change, air pollution, and water policies that will build on progress to transform its power sector. The plan sets […]

Droughts attributed to the El Niño phenomenon have gripped Venezuela’s neighbor Colombia. Bogotá in April prepared to ration power and instituted mandatory reductions in consumption, warning that

New worker training has traditionally meant classroom instruction and wading through a big pile of printed materials. But videos can offer deeper and more rapid understanding of critical issues, especially for younger generations. The Electric Power Research Institute has developed a series of videos to help power plants train new workers more effectively. Inexperienced new […]

Broadly put, today’s power plant operations are a mix of automated operations and manual or procedural steps. A plant may have hundreds of control loops, interlocks, permissives, and safety systems. In

“Why are you picking on the Clean Air Act?” That’s a question we’ve heard more than once while traveling the country to talk about our new book, Struggling for Air: Power Plants and the “War on

Air leaks cost money. According to the U.S. Department of Energy (DOE), over $5 billion per year is spent on energy to power compressed air systems. The DOE estimates that optimizing these systems could
