CHP: A Rocky Path for a Promising Approach
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 […]

Global CHP Still Struggling to Break Out of Its Niche
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 […]

Optimizing Combined Heat and Power in China
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 […]

Cyber Threats Proving Their Power over Power Plant Operational Technology
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 […]

Secure Connectivity Solution “Cloaks” Power Facility Networks
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 […]

Dry Cask Storage Booming for Spent Nuclear Fuel
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. […]

Best Practices for Aligning Safety Metrics, Incentives, and Performance
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 […]

American Electric Power: A Coal Powerhouse Repositions Itself
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 […]

Operational Considerations When Burning Higher-Chlorine Coal
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, […]

Understanding Coal Power Plant Heat Rate and Efficiency
Proposed U.S. standards for reducing carbon emissions from existing coal-fired power plants rely heavily upon generation-side efficiency improvements. Fuel, operations, and plant design all affect the overall efficiency of a plant, as well as its carbon emissions. This review of the fundamentals of coal plant efficiency, frequent problems that reduce efficiency, and some solutions for […]
