DETROIT EDISON HELPS SCHOOL SYSTEM INSTALL INNOVATIVE 'COOL STORAGE' SYSTEM

 ANN ARBOR, Mich., Sept. 8 /PRNewswire/ -- Detroit Edison (NYSE: DTE) today presented the Ann Arbor Public Schools with the final payment of a $68,000 incentive to install a system that uses low-cost electricity generated at night, to produce energy-efficient air conditioning during the day.
 The Ann Arbor schools will save at least $17,500 in annual energy bills by using the "cool storage" system installed recently at Pioneer High School. Cool storage -- an old idea recently revived as an energy- efficient alternative to conventional air conditioning -- involves freezing water overnight when both electric rates and demand are lower. The cooling needed for air conditioning the following day will be generated by melting the stored ice.
 As part of its cool storage pilot program, Detroit Edison offered incentives to the school system for installing the equipment and allowing the utility to monitor the system's efficiency for up to four years. The system became operational this summer.
 During a brief ceremony at Pioneer High, Lynette Taylor, manager of Detroit Edison's Ann Arbor Division, presented Robert Pierce, director of capital planning for the school system, with a check for $24,000. The utility paid the first installment of $44,000 last year. Representatives of Cummins and Barnard, the consulting engineering firm, also attended the presentation.
 "By encouraging customers to shift their energy use from daytime peak hours to the nighttime when demand and rates are lower, we can help customers manage their energy more efficiently," said Detroit Edison's Edward T. Henderson, coordinator of the program. "And, the system will pay for itself in three years."
 Henderson said that cool storage will allow the school system to get the maximum use out of the building. The Pioneer High system cools the school's cafeteria, student services, orchestra, band and auditorium areas. The 1,750-seat auditorium, the city's largest facility with free parking, is used for community and performing arts events year-round.
 The utility also is monitoring similar systems at Eastern Michigan University in Ypsilanti, the Chippewa Valley schools in Mount Clemens, Nissan's North American Technical Center in Farmington Hills and an NBD check-processing facility in Belleville.
