Construction was suspended on Watts Bar Nuclear Plant Unit 2 in the late 1980s, and the plant sat idle for more than 20 years. Now, through equipment refurbishment and replacement, Unit 2 is on track to become the first new commercial nuclear reactor to come online in the U.S. in the 21st century.  Electricity consumption […]

Boiler slagging and fouling, and the resulting frequent operation of sootblowers, are some of the major operations and maintenance factors that can negatively affect power plant reliability and efficiency. Boiler slagging and fouling are among the most common causes of maintenance headaches at coal-fired power plants. Though you cannot totally eliminate the problem, following proper […]

With unprecedented changes and challenges facing the U.S. energy sector, the Department of Energy has spearheaded a comprehensive assessment of the nation’s energy policy. Released the same day as ELECTRIC POWER 2015 opened, the first installment of this review was highlighted in the conference’s keynote address. U.S. energy infrastructure needs not just substantial investment for […]

The Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP) is feasible in its ultimate goals, but getting there will take a lot of work and some rethinking of how the targets are achieved

When many older plants were built, steel and cast iron piping were common materials used underground. Although these materials have proven to have long, useful lives, improvements in plastics offer additional alternatives today. An understanding of best practices for inspecting and servicing buried piping will help you keep systems operating as designed.  Most, if not […]

ALLETE Inc., a Minnesota holding company known mostly for its Minnesota Power subsidiary, is making a major strategic transition into the broader world of energy services, exemplified by its recent purchase of U.S. Water Services. At the same time, Minnesota Power, which previously transitioned from hydro to coal, now is shifting to a portfolio of […]

Given the costs and other concerns about currently available technologies for capturing and storing carbon dioxide from fossil-fueled power plants, interest in new technologies remains high. Here’s a look at some potentially promising approaches that are advancing the technology frontier.  Frontiers represent the boundary between the known and the unknown. As researchers attempt to push […]

Sometimes overlooked and underappreciated, a power plant condenser can make or break your efficiency and power delivery goals. Understanding how important a role your condenser plays is a good step toward greater heat rate awareness. As part of a university class on power generation systems that I teach, I show my students a Sankey diagram […]

Advocates for the continued reliance on coal for baseload electricity cheered late last year when North America’s largest power-related carbon capture and sequestration (CCS) facility was commissioned. Since then, that pool of advocates is evaporating as prominent electricity industry decision-makers publicly distance themselves from coal and champion alternatives for a low- or no-carbon future. If […]

For Samy Faried, an ABB expert who has spent 15 years analyzing arc flash hazards, a new rule recently finalized by the Occupational Safety and Health Administration (OSHA) will save lives. In April 2014, OSHA published its Final Rule for Electric Power Generation, Transmission and Distribution Standards (29 CFR 1910.269 and 1926 Subpart V), which […]
