O&MWhat Are the Safety Rules for Anyway?
Following safety rules is the foundation to eliminating injuries. Commonly, a safety presenter will say that safety rules are “written in blood.” At one time, such dramatic statements were a way to get attention and illustrated the seriousness of following safety rules. Today, more highly educated workers demand less drama and more facts.

O&MPredictive Maintenance That Works
This is the fifth in a series of predictive maintenance (PdM) articles that began in the April 2011 “Focus on O&M” in which the essentials of PdM were introduced. In the May and June 2011 issues, we explored specific PdM techniques, such as motor-current signature analysis and oil analysis. In the November 2011 issue, we introduced the value of thermographic analysis and its routine use. This installment focuses on ultrasonic and vibration analysis.

NuclearVogtle Gets Green Light
In February 2012, the Nuclear Regulatory Commission approved two combined construction and operating licenses for Southern Nuclear’s Plant Vogtle Units 3 and 4 in Georgia. They were the first licenses ever approved for a U.S. nuclear plant using the one-step licensing process and the first allowing construction in more than three decades. Now the real work begins.

Upgraded Controls Position McIntosh Plant for Efficient Operations
Lakeland Electric’s C.D. McIntosh, Jr. Power Plant is a microcosm of the entire power generation industry. On a single site is a once-baseload coal-fired plant that is now operating fewer hours plus a peaking gas-fired combined cycle plant that has swung to baseload operation. A complete controls upgrade of the gas-fired plant last year prepared the plant for its expanded role in producing electricity for this 108-year-old public power provider.

O&MManaging the Catalysts of a Combustion Turbine Fleet
Natural gas–fired fleets comprising diverse turbine unit types are operating their units more these days because of the historic low price of natural gas. With increased operating hours, fleet owners are challenged to find the best ways to manage their SCR catalyst systems.

Ensuring the Best Use of Federal Energy Subsidies
The U.S. uses a combination of direct expenditures, tax breaks, loan guarantees, and research funding to promote various energy goals. We could rely solely on the free market and avoid using federal subsidies, but we do not do that now and appear unlikely to do so in the future.

SolarThink Water When Designing CSP Plants
The operation of solar thermal power plants differs substantially from that of fossil-fired plants, as the sun determines the generation rather than market demand. However, design of the power island to minimize water usage is very similar to that of a fossil plant. This renewable technology requires renewed thinking of its water systems’ design.

CoalIndia Revs Up Capacity with Massive Coal Plants
India, a country that plans to fuel its current level of gross domestic product growth of between 8% and 9% with massive, mostly coal-fired power capacity additions over the next decade, in March commissioned an 800-MW supercritical unit at the first of India’s government-envisioned ultra-mega power plants (UMPP).

GasUkraine Looks Beyond Russian Gas
For years, tensions have been brewing between Russia, which provides about a quarter of the natural gas consumed in the European Union (EU), and neighboring Ukraine, a country through which 80% of those exports travel via pipeline.

BusinessGetting Bulk Storage Projects Built
Unpredictable periods of operation are one of the disadvantages of wind and solar technologies. If there were an economic means of storing the energy from the time of production to the time of demand, the value of renewable energy sources would greatly increase. Here are some ideas for how to bridge that gap.

Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy
The commercial development of nuclear power began immediately after the Second World War ended and the Manhattan Project secrets were released to the public. As the headline—also the title of a new book—implies, the development path was not always straight or even clearly marked. In this POWER exclusive, the first chapter of Too Dumb to Meter begins a serial presentation of the book.

NewsPowered by Felt
It promises to be the most widely and easily distributed power generation technology to date: heat, captured in fabric. Work at Wake Forest University in North Carolina has led to the creation of a thermoelectric fabric called Power Felt that can turn theoretically any form of heat (body heat, waste heat from a car, or heat from any other source to which the material can be attached) into sufficient electrical current to help power devices or the systems the material is in contact with.
