COAL AND ASH HANDLING: IN SEARCH OF COST SAVINGS - Coal and ash handling is often thought of as a necessary evil because these functions typically incur costs without contributing to power production. Efficiency improvements are available, however, if one is willing to look hard enough, as are revenue opportunities, primarily on the back end in terms of fly ash separation and marketing| 2003

UNIQUENESS OF SCR RETROFITS TRANSLATES INTO BROAD COST VARIATIONS - Many coal-fired power plants are installing selective catalytic reduction (SCR) systems to control NOx emissions. An analysis of more than 20 SCR projects indicates that cost predictions from the mid-1990s were low and that site-specific factors and scope differences contribute to a wide range of costs, from (USD)80-160-kWnet without adjustment for labor cost differences| 2003

BOILER FEEDWATER TREATMENT: IMPROVEMENTS IN CONTINUOUS ELECTRODEIONIZATION - Over the past decade, the power industry has increasingly relied on the use of reverse osmosis (RO) as a roughing demineralizer to remove the bulk of the mineral, organic and particulate contaminants from boiler feedwater. More recently, improvements in continuous electrodeionization (CEDI) technology have caused a movement toward chemical-free deionization systems, as RO-CEDI has become more cost competitive with conventional ion-exchange technology| 2003

ANCILLARY MARKETS PROVIDE REVENUE OPPORTUNITY FOR UNDER-UTILIZED GAS TURBINES - As regional electricity markets mature, an approach that is gaining favor for value optimization is to leverage existing equipment to economically participate in synchronous condensing and spinning reserve markets. In the PJM system, for example, where a spinning reserve market opened for business in December 2002, several asset owners have taken advantage of this revenue opportunity by adding synchronous clutches to new gas turbine generators| 2003

MANAGING THE PLANT: MOUNT PLEASANT UTILITIES - As local power demand in Mount Pleasant, Iowa, grew throughout the 1990s, reaching nearly 20 MW during peak periods, the city's generation assets could not keep pace. In recent years, Mount Pleasant had to pay almost (USD)1 million in capacity charges to cover its generation shortfall. The city decided to retire its aging steam turbine and install 12 new 2 MW diesel generator sets, using the savings in capacity charges to service the project debt| 2003
