18 Repair or Replace Projects As repairs or replacement of items that use energy arise, energy efficient products are incorporated. Energy efficient exhaust fans and roof top heating units replace older versions, when needed. Exterior light timers replaced with astronomical digital timers, when needed. Broken light fixtures replaced with LED fixtures. 18

19 On the Horizon Solar 19

20 What s next? - SOLAR! MPS is committed to continuing to reduce energy consumption and saving money Solar energy makes sense - New roofs on school - Government and Utility incentives make it affordable No up-front capital costs MPS/City will lease the roof space for 20 years solar is installed and the units maintained by the developer MPS purchases the energy at a reduced cost 20

21 SOLAR MPS issued an RFP for a Solar Energy Developer/Partner Received responses from 8 nationwide developers Interviewed 5 firms Second interview with 2 finalists 21

22 SOLAR Selected Davis Hill Development/Skyview Ventures Selection based on: Depth of experience Strong recommendations Experience working in other Connecticut municipalities and school districts 22
