6th Consecutive Year – School Division Reduced Utility Costs…
Energy Reduction Efforts
While the average cost of electricity to SCPS rebounded 11% from $.079 to an average cost of $.088 per KWH for all
usage

History◦ Opportunity to reduce energy consumption by
modernization of facility systems through Energy Conservation Measures (ECMs)
LightingOccupancy SensorsMotors & Fan DrivesWater Conservation
◦ Utilized State Contract to evaluate and select an
energy performance contractor ◦ Contracts funded through annual energy savings
