How accurate is the degree day delivery system?
It tends to be reasonably accurate during the winter months but somewhat less accurate during the fall and spring. The accuracy can also vary from customer to customer. This winter, Hart & Iliff began testing a new delivery system developed by the Energy Research Center Inc. This system is called Delivery Cost Reduction (DCR). How does the DCR System work? DCR is a patented delivery system developed by an engineer and a physicist. It uses degree days, the passage of time, regression analysis and a series of mathematical formulas to determine the appropriate time to make a delivery. How accurate is the DCR System? Preliminary testing indicates that delivery differences with the DCR System are generally less than 1% and the average fuel delivery projection is typically within 10 gallons of the actual delivery. When will Hart & Iliff begin using the DCR System? Hart & Iliff is one of the first oil companies in the country to test this new delivery system. Our plan is to deliver through th
