Energy Reduction Efforts

6th Consecutive Year – School Division Reduced Utility Costs…

While the average cost of electricity to SCPS rebounded 11% from $.079 to an average cost of $.088 per KWH for all usage

Energy Reduction Efforts
  • Dollars Saved Compared 2005 to 2011
  • 2005 248,639,864 = 72,872,176 KWH x $.088 = $6,412,751
  • 2006 231,703,193 = 67,908,321 KWH x $.088 = $5,975,932
  • 2007 207,403,347 = 60,786,444 KWH x $.088 = $5,349,207
  • 2008 196,067,563 = 57,464,115 KWH x $.088 = $5,056,842
  • 2009 172,592,046 = 50,583,835 KWH x $.088 = $4,451,377
  • 2010 185,097,785 = 54,249,057 KWH x $.088 = $4,773,917
  • 2011 158,002,092 = 46,307,764 KWH x $.088 = $4,075,038
  • WITH NEW SCHOOLS
  • 2007 246,594,352 = 72,272,670 KWH x $.088 = $6,359,994
  • 2008 235,724,780 = 69,086,981 KWH x $.088 = $6,079,654
  • 2009 217,896,755 = 63,861,885 KWH x $.088 = $5,619,845
  • 2010223,409,383= 65,477,544 KWHx $.088 = $5,762,023
  • 2011 196,071,320 = 57,465,216 KWH x $.088 = $5,056,939
  • From Dominion
  • $3,288,210 / 37,443,980 = $.088 - KWH

Energy Reduction Efforts
  • Environmental Impact

125,165 TONS of Carbon Dioxide (CO2) NOT EMITTED INTO THE ATMOSPHERE.

  • THIS IS THE RIGHT THING TO DO!

Energy Performance Contract
  • Phase II – Update
    • Selected 4 energy conservation measures (ECM’s)
      • ECM #1 - efficient lighting
      • ECM #2 - occupancy sensors in classrooms, (hallways, offices, gyms)
      • ECM #3 - water conservation (low flush)
      • ECM #4 - variable fan drives & efficient motors for HVAC equipment 
  • Estimated Annual Energy Cost Savings = $199,500.00 per year guaranteed
