  1. How these projects fit in with the PPS overall energy strategy Roof-Tops – 2 MWs Purchase Electricity Offsite Solar – 6 MWs Purchase Electricity Credits Plymouth Public Schools – Solar Projects

  2. PPS Energy Strategy - Details • Our energy strategy is divided into three components: • Conservation- This was the starting point for the districts energy program, conservation efforts involving all district personnel are the anchor of our program. Conservation efforts have helped to achieve a substantial amount of the savings we have seen to date. • Efficiency Initiatives- We have completed and continue to move ahead with efficiency projects including lighting upgrades, mechanical upgrades, and building envelope improvements, as well as the larger capital projects that are significantly driving down our overall consumption. • Alternative Energy Options • - proposed projects: roof-top onsite and offsite solar farm projects. The direction we are taking; conservation→efficiency→alternative energy is the energy industry recognized standard path for large facility energy programs.

  3. Energy Efficiency Activities – • Energy Efficiency Projects: • LED installations • Controls upgrades • De-stratification fans • Hot water heater replacements

  4. Energy Efficiency Projects - Convert 4 Schools to Non-Electric/Lower Cost • Capital Projects: • PCIS- complete • West- complete • Indian Brook- project underway targeted for completion summer 2012 • Federal Furnace- not yet approved but anticipated, existing system at the end of its life cycle.

  5. PV Solar Energy Projects – • Photo Voltaic Solar Electricity Generation - Municipalities allowed to purchase 10 MW of Electricity credits. Net-Metering Credits • Six Schools – Roof-Top PC Solar Systems • Two (2) MWe of Capacity – 2,300,000 kWhr / yr • Saves $0.8 / kWhr or $184,000 / year • Offsite PV Solar Farm Project (s) • Six (6) MWe of Capacity – 9,390,000 kWhr / yr • Saves $0.6 / kWhr or $563,400 / year

  6. Plymouth Public Schools Electricity Cost Profile to be built into the FY13 energy projections
