statewide energy partnership
Statewide Energy Partnership
  • 3-year agreement between CPUC, IOU’s, UC, CSU
  • Annual reduction and incentive goals
  • $40M project cost over 3-years
  • Year one goal – 16,097,345 kWh & 434,844 Therms
  • Organization couldn’t meet year one goals
  • Utilize ESCO-like best value design-build contract
  • Performance guarantee
    • Annual kWh and therm reduction
    • Maximum acceptance cost (MAC)

Energy Projects Going Forward
  • Evaluate your organization
  • Design-build with specialized contractors
    • Less control over design
    • Constant Air Volume to Variable Air Volume
  • Unit price contract
    • Lighting
  • Design – bid – build
    • Retain engineering and design control
    • Exhaust Stack Discharge Velocity Reduction / Wind Response
    • Heavy interaction with end-users
      • CDCV in Vivaria
  • MBCx
