Design techniques and operating experience with Powder River Basin (PRB) coals have advanced significantly over the past 35 years for boilers that were originally designed for this fuel. Today, boiler installations looking to effectively utilize PRB coals fall into two primary categories: units that were initially designed for bituminous or other coals and units that […]
The sale or merger of any company takes its toll on employees. Though it’s merely a hassle adapting to a different T&E form, the sudden uncertainty about health-care coverage and pension can be truly stressful. For plant managers, the impact is even greater—adapting to a new budgeting process and reporting requirements, not to mention answering hundreds of subordinates’ questions about the future, even before the deal closes. However, plant managers may actually end up better off as a result of a merger or acquisition.

The latest benchmarking study by the EUCG examines the engineering and technical staffing of 62 plants, 92% of which burn coal. If you benchmark your units, plants, or fleet, the results may raise some eyebrows. But they also may help justify your plea for more intellectual capital during the upcoming budgeting cycle. Though the detailed results of the study are proprietary to EUCG member companies that participated in it, POWER was given access to the complete findings. If you want details at the plant/unit level, you’ll have to join the EUCG and participate in the study, which is ongoing.
Although fluid monitoring technology has come of age in recent years, its level of sophistication varies widely across industries. Some users of bulk chemicals, fuels, and other fluids use state-of-the-art systems with bells and whistles like automated data gathering and transmission. At the other extreme, some tank farms still “stick the tanks.” Although 95% of large […]
Hydroelectric power plant managers face unique scheduling challenges. They have a finite amount of water in their reservoirs available for energy production, and they need to schedule generation according to market demand to maximize profits from their limited “fuel” supply. Hydro power plants are capable of producing products other than electricity. Among them are ancillary […]
Five years ago, San Onofre Nuclear Generating Station’s Unit 3 turbine experienced substantial damage after the supply of oil to its bearings failed. Because the turbine coasted down without oil after it tripped, its bearings, journals, and steam path needed extensive repairs. A follow-up investigation revealed lube oil system vulnerabilities that were subsequently corrected. The lessons learned might also improve your turbine-generators’ lube oil reliability, saving you many millions in lost revenues.
The pressure on power producers to supply reliable electricity is unyielding. Forced outages, which usually are caused by unexpected component failure or systemic problems, can prove very costly to both bottom line and reputation. To reduce the frequency and duration of unscheduled outages, many gencos are implementing comprehensive predictive maintenance (PdM) programs. Such is the […]
Kansas City Power & Light Installing SCR at La Cygne Generating Station Kansas City Power & Light (KCP&L), a subsidiary of Great Plains Energy, has awarded The Babcock & Wilcox Company (B&W) a contract for the installation of new emissions control equipment on Unit 1 at its La Cygne Generating Station. When completed, the selective […]
Between 1998 and 2002 the U.S. experienced an unprecedented power plant construction boom that consisted mostly of gas-fired, combustion turbine – based power plants. This surge in power plant construction had several driving forces, including electric power deregulation, the emergence of non-utility power producers, a sustained period of plentiful and inexpensive natural gas, and the […]
