The challenge was to take a facility that was far off the grid, and move it forward as an energy self-sufficient complex while also turning an idea into a commercially viable product. That was the impetus

Self-contained, small islands of electric generation, storage and distribution inside the existing grid–microgrids–could be the next big thing in electricity. But some argue they may be just another

Grid behavior in today’s power generation environment is a stochastic system that is more variable than in the past. One common issue is the response to economic dispatch, in which formerly baseload thermal

Southern Co.’s Plant Scherer was chosen as the 2017 Powder River Basin Coal Users’ Group Plant of the Year based on a rigorous selection criteria, including safety, fire protection, and risk reduction

Electrostatic precipitators (ESPs) offer a tried-and-true technology for particulate matter control. However, existing ESPs can be challenged to meet the latest regulatory requirements. Retrofitting power

Some naysayers have argued that developing carbon capture technology for use on fossil-fueled power plants is pure folly. But research and pilot tests have continued nonetheless, and various solutions have

With low particulate loading common in stack emissions these days, particulate matter measurement can be difficult using traditional techniques. Microscopical measurement of particle-size distributions offers

Regulatory agencies are becoming more and more critical of phosphorus-based water treatment chemicals because they can have a negative impact on lakes and waterways. In the past, treating cooling water with

Coal proponents and climate skeptics often cite China’s current and future reliance on coal power to bolster talking points. What is little discussed is the recent, massive transformation of China’s vast

Proportional-integral-derivative (PID) control is one of the most common types of automatic control used in the power industry. A PID controller continuously calculates an error value as the difference between

Small hydro is becoming big business as ongoing technological advances make more small sites economic to exploit. Older plants can also see substantial output and efficiency gains by upgrading from decades-old

What it means to have a secure energy generating facility has changed in recent years as the threat of cyberattacks grows. As the nation’s energy sector becomes increasingly interconnected, it is more

Technology advancements and new regulatory requirements could reshape how power plant owners operate and maintain large power transformers. Experts outline emerging strategies and call attention to overlooked

New technology is being used throughout the power industry to improve plant efficiency, predict trouble with degrading equipment, forecast weather trends, and train workers. A recent conference hosted by POWER

Continuous condition-based monitoring of electrical conductors and insulation is an effective way to reduce required plant maintenance activities, cut operating costs, and prevent unplanned shutdowns

Remote and online monitoring of plant performance parameters is an important step toward a fully connected plant, but alone it’s not enough to exploit the real value in the Industrial Internet of Things, speakers at POWER’s inaugural Connected Plant Conference on February 15 in Dallas said. Randy Bickford, president and CTO of software firm Expert […]

Background burner control is critical for power and industrial plants because it affects emissions, energy costs, and process efficiencies. For natural gas burners, variations in gas composition can have a

A magnetic level gage may be an excellent addition to a power plant boiler’s drum-level instrumentation. However, before any changes are made, owners must first understand the specific minimum requirements for water level instrumentation defined by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. The code requires a functional water gage […]

China, which continues to build more new coal plants than any other nation, is also on the forefront of deploying the most advanced coal plant technologies. However, these advanced units could face

As installed capacity in the U.S. continues its breakneck growth, the solar photovoltaic sector is poised for another leap forward with a variety of new technologies—if increasingly ill-suited regulations and rate designs can be updated to keep pace. The global solar market has moved beyond its early, uncertain days. The luxury of behaving like start-ups […]

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 […]

Asset data is crucial in the power generation industry. Without it, utilities are forced to speculate about how long their assets will last, when they will need repair, and which strategies will maximize plant efficiency. With it, plant owners have the tools to drive down operational and maintenance costs while ensuring highly reliable power delivery. […]

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 […]

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 […]

Power plants are familiar with using continuous emissions monitoring systems (CEMS) to monitor pollutants, but these devices also may be able to measure heat rate—which could be handy for future compliance with the Clean Power Plan. Continuous emissions monitoring systems (CEMS) are used to monitor power plant flue gas emissions as a means to comply […]

Projections that coal utilization will decline faster than previously forecast have spurred Babcock & Wilcox Enterprises (B&W) to shed 200 jobs and restructure its traditional power business that serves coal-fired power generation in a bid to reduce overhead and improve efficiency. The Charlotte, N.C.–based energy and environmental technology and service company said on June 28 […]

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 […]

Ensuring the reliability of the power system is the responsibility of many industry participants. In this POWER exclusive, one regional reliability entity, the Midwest Reliability Organization, explains its role. In response to the 2003 Blackout—which affected parts of the U.S. Northeast and Midwest, plus portions of the Canadian province of Ontario—the U.S. Congress mandated adoption […]
