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, […]

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 […]

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 […]

In China, small hydropower (SHP) development not only provides power, especially to rural areas, but it also plays an important role in developing local economies and human capacity building. Regions, rather

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
