Nuclear power station water storage tanks, located above ground or underground, are constructed of aluminum, stainless steel, or carbon steel. All have naturally occurring electro-chemical processes that can eventually deteriorate the metal, resulting in leaks. Defects that develop on the underside of tank floors are particularly difficult to detect and measure. The Nuclear Energy Institute […]

One oft-cited roadblock to widespread adoption of plug-in electric vehicles (PEV) is a lack of charging infrastructure, commonly referred to as electric vehicle supply equipment (EVSE), or charging stations. While Tesla is well known for designing electric vehicles that can travel more than 250 miles on a single charge, most PEVs can only travel 60 […]

Combining electric power production with use of steam for heating, cooling, and industrial processes is an old idea that had a brief boom in the U.S., kicking off the rise of non-utility generation. Since then, combined heat and power, or cogeneration, has become a niche market player. What happened? In the late 1990s, the University […]

Despite its efficiency and environmental benefits, combined heat and power (CHP) generation has languished at around 10% of worldwide capacity for more than a decade. But a global review shows growth in some sectors and promising new technology on the way. The statistics are both eye-opening and somewhat depressing. Globally, according to the International Energy […]

As it struggles to grow its economy while improving air quality in urban areas, China is updating its energy delivery infrastructure. A key part of that plan is switching from coal-fired to gas-fired combined heat and power plants. To push efficiency even further, some plants are turning to synchronous clutches. The developed world has done […]

The threats to power industry operations—and the reliable supply of power that we all depend upon for daily life—are no longer theoretical. A roughly 250% spike in reported industrial control system incidents over the past four years demonstrates that regulations alone will not protect power infrastructure. Everyone who works in this industry needs to develop […]

One of the persistent challenges for power sector cybersecurity is integrating operational and information technology teams and functions, especially when they include remote or third-party systems. A new military-grade security approach provides industrial control system security without compromising ease of daily operations. What do power generating companies have in common with The Boeing Co.? The […]

A combination of spent fuel pools reaching capacity, security concerns, and mostly nonexistent policies regarding long-term consolidated storage of nuclear waste is making dry cask storage the only way forward for most nations with nuclear power reactors. Around the world, demand for dry cask storage facilities for spent nuclear fuel (SNF) is on the rise. […]

The world’s ocean energy sector, which has over the past few years seen its share of developmental ebbs and flows, suffered a major storm this November after Siemens Energy said it would sell its tidal power arm and Pelamis Wave Power separately failed to raise needed funds to continue development. Siemens in February 2012, with […]

The Occupational Safety and Health Administration requires certain incidents to be recorded and reported, which generates a set of statistics that many companies use to gauge safety performance. However, other metrics may be better predictors. The Occupational Safety and Health Administration (OSHA) requires all employers with more than 10 employees, and whose establishments are not […]

On Nov. 14 at Los Angeles Air Force Base, California (L.A. AFB), U.S. Air Force officials unveiled the Department of Defense’s (DOD’s) first nontactical vehicle fleet composed entirely of plug-in electric vehicles (PEVs). Actual rollout of the 42-vehicle fleet happened prior to the official ceremony, Christina Greer of the base’s Public Affairs office told POWER, […]

American Electric Power, one of the premier generating utilities in the U.S., is caught between a deregulated rock—wholesale competitive capacity markets that don’t, in the company’s opinion, value solid equipment over ephemeral demand response—and a regulatory hard place of increasing federal government rules that devalue on-the-ground coal-fired generation. Add the competitive challenge of cheap natural […]

Most readers will receive this issue while they are experiencing Northern Hemisphere winter, with its colder temperatures and higher energy bills, so it’s fitting that several articles address efficiency. You’ll find discussions of combined heat and power (CHP) as well as a refresher on the various ways to enhance thermal unit efficiency and thereby improve […]

An increasing supply of low-cost higher-chlorine coal is prompting many U.S. generators to give the fuel serious consideration in spite of its reputation for causing corrosion. Though corrosion can be a consideration, it’s not always caused simply by the fuel switch. Understanding the various chemical interactions, as well as operational and emissions pros and cons, […]

Much has been made recently of Mexico’s energy sector reforms, and because those reforms are still in being implemented, it can be useful to compare their progress with the outcome of previous reforms in Latin America. (A condensed version of this material appears in the January 2015 print issue of POWER: “Can Mexico’s Electricity Reform […]

As the global electric power industry continues to develop clean, high-quality energy capacity for sustainable development, the position of small hydropower has changed. In the past few decades, small hydropower development in China has experienced positive momentum, but there are still problems to be solved. To solve these problems, various relationships within the small hydropower […]

The urge to merge, a key feature of the power industry for the past 20 years or so, showed no signs of slowing in 2014. Major players sought to beef up their asset portfolios and diversify their generating

Almost a year ago, workers began pouring concrete for the basemat of the first small modular reactor (SMR) in the western hemisphere. Despite the hype over SMRs in the U.S., with hundreds of millions of

The Black Oak Wind Farm project is an 11.9-MW wind facility under development in Tompkins County, N.Y., a few miles west of Ithaca. For the most part, Black Oak is unremarkable—the community-owned facility

The global power industry is becoming increasingly complex. Trends toward greater amounts of variable renewable energy are changing the requirements for conventional power plants. Energy market policies are

The particulate matter (PM) requirements of the Mercury and Air Toxics Standards (MATS) require filterable PM emissions less than 0.03 lb/MMBtu, which will demand greater particulate removal efficiency from

Back in the “good old days” of the power industry, fuel was cheap, fuel supplies were fairly constant, air emissions regulations were loose, and power plant coffee was as dark as sin and worse for you

Over the last few years, it has become increasingly clear that a massive cyber-attack on the North American electric grid represents a serious threat to U.S. national security. Over time, a string of senior

A pilot plant in Andalucía, Spain, built by a consortium of multinational European partners, is converting toxic waste from olive oil production into electricity using an innovative three-part process

Oregon and Washington State are examining new policies to regulate greenhouse gas emissions. We expect to see extension of Oregon’s Clean Fuels Program at the top of the 2015 legislative agenda and

Candu Wins China’s Backing to Develop AFCR Projects. Candu Energy and the China National Nuclear Corp. on Nov. 10 signed a framework joint venture agreement to build Advanced Fuel CANDU Reactor (AFCR)

Energy market dynamics in the U.S. continue to evolve. Regulatory developments, advancements in power plant technology, and fuel dynamics are transforming the industry. Although the outcome of these

The trial operation of a steam loop for more than 17,000 hours at temperatures exceeding 760C (1,400F)—the highest ever tested at a pulverized coal plant—have wrapped up at Plant Barry Unit 4 in Alabama

“When pigs fly” is a figure of speech used to express disbelief that a particular situation will ever come to pass. For the power industry, several recent and emerging developments are the equivalent of
