2 National Town Meeting What is informational feedback? ♦ The provision of information to customers about their energy consumption patterns and costs ♦ There are two types Indirect feedback: information processed in some fashion before it reaches customers (e.g. detailed billing treatments) Direct feedback: information readily available upon demand by the customer, e.g., through an “in-home display (IHD)” device

3 National Town Meeting IHDs provide several benefits Customers ♦ Lower bills ♦ Feeling of being in control ♦ Smaller carbon footprint Utility ♦ Avoided incremental capacity and T&D investments ♦ Energy savings may contribute towards RPS and EERS in certain states ♦ Smaller carbon footprint would help cope with emerging federal carbon pricing policy ♦ IHDs used in conjunction with time-varying rates may also augment demand response

4 National Town Meeting Are the benefits real? We reviewed a dozen pilot programs to see if customers responded to IHDs by lowering energy consumption and reducing peak demand ♦ In our review, we address the following considerations Structure of the pilot program Energy consumption impacts of IHDs Demand response impacts of IHDs Customer opinions about the usefulness of IHDs

5 National Town Meeting Programs reviewed

6 National Town Meeting Programs reviewed (cont’d)

7 National Town Meeting Limitations The pilots considered in this study are heterogeneous in terms of pilot structure and design ♦ Utilities and geographic locations involved in the pilot studies vary widely, as do the demographics of the consumers ♦ Consumers are subject to various electricity tariffs ♦ Only a few involve randomly selected and balanced treatment and control groups ♦ Only a few tested for persistence of the impacts We are unable to control for differences in the structures of the pilots

8 National Town Meeting The bottom line Direct feedback provided by IHDs encourages consumers to make more efficient use of energy Energy savings range from 2.7% to 18%, with an average of 7% When combined with an electricity prepay program, energy savings are about twice that amount In a few cases ♦ The effects of time-varying rates on peak demand and energy consumption are augmented by IHDs

9 National Town Meeting Estimated pilot impacts

10 National Town Meeting An agenda for the future Is the information itself useful to customers, or do IHDs simply serve as a physical reminder to conserve? Are the impacts going to persist over time? How would IHDs work with dynamic pricing? Are customers willing to pay for IHDs?
