3. BGE’s OPOWER Pilot  On May 21, 2010, the Baltimore Gas and Electric Company (BGE) filed with the Maryland Public Service Commission a request for approval of a Pilot Program featuring an innovative direct mail campaign (BGE Home Energy Report) designed to:  Better inform participants about their existing energy consumption  Encourage customers to use less energy  Increase participation in the energy efficiency components of BGE's Smart Energy Savers Program® 3

4. BGE’s OPOWER Pilot  BGE tested a targeted direct mailing to 25,000 BGE residential customers using energy reports based on a program developed by OPOWER  BGE sent seven test mailings every other month from October 2010 to September 2011 to 25,000 customers  The pilot customers were randomly drawn from BGE’s entire residential customer base and included both electric only and gas and electric customers  To fully test the campaign’s effectiveness, a control group of 25,000 customers was also selected  These customers did not receive the direct mailings 4

7. Cost-effectiveness Recommendation: Apply the same cost-effectiveness standard to a Home Energy Usage Report Program as you would any other EE Program 7

8. Cost Recovery Recommendation: Apply the same standard to a Home Energy Usage Report Program as you would any other EE Program 8

9. Opt-in vs. Opt-out Recommendation: It is reasonable to allow the default option for Home Energy Usage Report Programs to be Opt-out 9

10. Increasing Participation in Utility Energy Efficiency (EE) Programs Recommendation: Consider adding a cost-effective Home Energy Usage Report Programs to a portfolio of utility EE programs to increase participation 10

11. EE Programs vs. Advanced Meter Infrastructure (AMI) Programs Home Energy Usage Report Programs are feasible without any AMI data Some Home Energy Usage Report Programs provide additional information based upon AMI data 11
