Just when the power generation industry was stabilizing along came mega government regulations and changing economic conditions that threw a monkey wrench into the works. Although improved inventory practices have helped solve some coal problems, other still remain. The Clean Air Act has resulted in fuel switching, blending, equipment changes, and other factors, all contributing to power plant personnel grey hair. Then along came Just-In-Time inventory practices. Not only is the plant required to make all these changes to meet regulatory requirements, but reduce the quantity of fuel in inventory to unheard of low levels. Why is it so difficult to precisely account for coal in inventory? After all, inventory is a simple matter of accurately measuring the coal coming in to the plant, measuring the coal used by the plant, and conducting an accurate physical inventory to measure the remaining coal. Add to this, a major coal inventory reduction policy, when base maps are not maintained or updated and are, therefore, not likely to be accurate. Some coal may have been stored below the prevailing water table, rendering the coal unusable. Weather conditions, such as major ice storms can render much of the coal unburnable. Unless accounted for, these things reduce the perceived amount of coal in inventory. This presentation will address these issues to assist in preventing potential unscheduled plant shut down and the need to purchase unscheduled blocks of emergency power. Just-In-Time Inventory isn`t as straightforward as first meets the eye.
