The Lodi Energy Center (LEC) is a 296-MW 1 x 1 combined cycle plant in Lodi, Calif., just north of Stockton and east of the San Joaquin River delta (Figure 1). From the outside, there’s little to distinguish

Selective catalytic reduction (SCR) systems installed in steam generators for NOx reduction are ordinarily designed for full boiler load conditions, when SCR inlet temperatures normally exceed unit-specific

Geothermal resources have important strategic value for New Zealand, as they are able to directly supply both heat and electricity (see “New Zealand Geothermal Industry Is Poised for the Future” in this

Late last year, Japanese engineers and technicians accomplished a major milestone nearly four years after the most damaging light-water reactor accident in history at the Fukushima Daiichi nuclear station

Contact Energy fully commissioned New Zealand’s largest geothermal power plant last year, nudging installed geothermal capacity to a shade over 1 GW. Nearly 80% of the country’s electricity is sourced from

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, 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 […]

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 […]

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 […]
