1. Santee Cooper Encouraging Energy Efficiency APPA National Conference June 15, 2009

2. 2 Santee Cooper Goal Conservation/Energy Efficiency Programs & Plans New Proposed Rates Consumption Monitor Overview Santee Cooper Energy Efficiency Overview

3. 3 Santee Cooper’s Goal On October 19, 2007, Santee Cooper’s Board of Directors adopted a goal of “obtaining forty percent (40%) of its gross electric generation needs from non- greenhouse gas emitting resources, biomass fuels, energy efficiency and conservation by 2020”

4. 4 Conservation / Energy Efficiency Programs –Energy Efficient Lighting Program Began April 22, 2008 Over 65,000 customers participated Over 800,000 bulbs distributed Over $1.6 million spent –Energy Efficiency Low Interest Loans Began in 1982 Loaned out over $17 million since inception $3.5 million in loans outstanding 1.25% is current interest rate –Good Cents (Energy Efficient) Home Program 678 calculations completed in 2008 374 certifications issued in 2008 –In-Home Energy Audits 372 completed in 2008

5. 5 Conservation / Energy Efficiency Programs (Cont.) –Santee Cooper Facilities’ Energy Audits 40 facilities audited $1.25 million estimated cost of efficiency improvements –Public Facilities (Local & State) Energy Audits 28 facilities audited –Power Cost Monitor Pilot beginning early 2009 400 residential customers $200,000 program budget –Energy Efficiency and Demand Response Plan 42 new measures implemented over next 3 years 209,000 MWh of new savings in year 2020 73 MW of new savings in year 2020 Over $113 million spent by 2020 for new programs

6. 6 New Proposed Rate Structure –Proposed effective date of Nov. 1, 2009 –Seasonal rate structure –Reflects higher summer cost of generation

7. 7 Santee Cooper Residential Consumption Monitor Pilot Program 33% of home energy use in U.S. is attributable to residents’ behavior * Other pilot studies show that real-time electricity consumption information given to the customer can result in an average annual savings of up to 6.5%. No research is currently available for consumer behavior in Southeast. * Sonderegger, 1978

8. 8 Santee Cooper Residential Consumption Monitor Pilot Program Power Cost Monitor from BlueLine Sensor unit attaches around meter housing Eye on sensor unit picks up meter’s disk rotation or electronic pulse signal Sensor unit w irelessly sends information to in-home display In-home display is programmed with customer’s rate In-home display unit shows: - How much electricity is being used in real time - How much money is being spent on electricity as it is consumed - Highest amount spent on energy usage in a 24-hour period

9. 9 Santee Cooper Residential Consumption Monitor Pilot Program The Energy Detective (TED) Current transformers installed in electrical panel measure current being used Information sent to measurement transmitting device Information sent to in-home display through power line carrier In-home display is programmed with customer’s rate In-home display shows: - How much electricity is being used in real time - How much money is being spent on electricity as it is consumed - Highest amount spent on energy usage in a 24-hour period

10. 10 Santee Cooper Residential Consumption Monitor Pilot Program Participant Qualifications Customer must occupy dwelling and have 24 months of account history Customer agrees to have energy audit Manufactured, site-built, and multi-family dwellings are eligible

11. 11 Santee Cooper Residential Consumption Monitor Pilot Program Goals Determine if customers value the availability of real-time electricity usage information Determine if customers will use this information to control their energy usage Determine level of customer energy savings Determine appropriate program offer and technology for overall deployment of consumption monitor

12. 12 Santee Cooper Residential Consumption Monitor Pilot Program Proposal Conduct a pilot program with 400 residential customers Design pilot such that the most suitable monitor deployment is determined Charge customer $9.99 for shipping cost Third-party to perform surveys for measurement, verification and data analysis

13. 13 Santee Cooper Residential Consumption Monitor Pilot Program Proposal (Cont’d) Use results of pilot to determine program offer to residential customers Use results of pilot to determine the best way to educate the customers on how to take control of their energy usage Implement program for residential customers

14. 14 Santee Cooper Energy Efficiency Questions?
