Florida DR and Energy Efficiency Background

• Florida has engaged in Demand Response and
  Energy Efficiency Since 1980
• Demand Response and Energy Efficiency are part of
  each major Florida utilities' annual planning
  process
• Florida utilities consistently look first to
  Demand Response and Energy Efficiency to meet
  growing electricity demand
• Florida ranks 2nd among states in Demand Response
  and Energy Efficiency1

Lessons Learned

• What Didnt Work
• Building Code Impacts
• What Works Well

36
What Didnt Work

• Increased Incentives no Guarantee of Increased
  Participation
• Goal Setting must be from market potential and
  not from Top Down approach
• Keep it Simple
• Rebate process and rules have to be extremely
  easy to understand and follow to get maximum
  participation
• Advertising One size doesnt fit all
• Commercial customers require relationships to be
  established with customer and equipment vendors
• Gateway Communication 1998
• Technology not ready and costly
• Concept ahead of technology
• Residential Paid Audits
• Additional time and information not accepted
• Load Control programs can grow too large a
  percent of reserves

37
Building Code Impacts

• 1990 Code change from SEER 10 demonstrates slow
  transition to hi-efficiency Heat Pumps 7 years
• Record number of implementations in 2006 with
  less than 50 of that number expected in 2007

50 drop
38
What Works Well

• Duct Seal Repair
• Over 660,000 ducts repaired/sealed
• Success due to education of consumer
  contractors to address an invisible issue
• Duct curriculum and training developed and
  delivered annually to AC contractors
• Direct Load Control has 1.2M customers
• Saved 16 of Total USA Peak Demand Reduction1
• Florida placed 2 utilities in Top Ten of Nation1
  in MW of EE DR
• Developed multiple delivery channels
• Field representatives and account managers
