Since the collapse of Enron and the wholesale power markets, the vitality of competition in retail markets for electricity has waned in most regions of the U.S., with the exception of Texas. At KEMA’s 21st annual Executive Forum in late March, 300 attendees converged on Dallas to discuss and debate the dynamics and changes now facing residential and commercial customers in most regions of the U.S. and Canada. Founded in 1927, KEMA is a global provider of business and technical consulting, operational support, measurement and inspection, and testing and certification for the energy and utility industry. A summary of the many presentations follows.

Dresser Waukesha is a familiar name associated with large, gas-fueled stationary engines for power generation and gas compression applications around the world. Each new project location presents a unique set of site variables that must be taken into consideration—such as fuel quality, air/fuel ratio, temperature, humidity, altitude, load, and exhaust after-treatment—when providing the customer a meaningful performance guarantee. To fully characterize every engine option with such a wide range of fuel types and quality and in widely varying environmental conditions across the global is an impossible chore.

An oil skimmer could simplify your plant water maintenance activiites.

Timing is everything in the world of electric power generation. The timing of the delivery of electricity is affected by both the users’ demand and the speed with which a variety of energy sources supply power to the transmission system. Modern grids require reliable energy sources to instantly meet the needs of their users.

Fast-starting combined-cycle plants are designed for a certain operating life based on a customer-specified set of operating scenarios. During that design phase, periodic inspection and maintenance procedures to benchmark equipment actual wear and tear should be developed, but seldom are. Without an accurate assessment of remaining equipment life for components subjected to fast and frequent […]
