2. Premise: Provide detail on all Electric Rate components to establish a foundation upon which energy policy choices are developed. The Challenge: High Rates Multiple Policy Commitments Operational DisadvantagesContext: Some good news.... CT electric rates are declining. CT has choices today that were not available during most of the last decade. STATUS OF 3 KEY COST DRIVERS Sufficient Generating Capacity Improved Transmission System Commodity Price Stability Highly recommend review of Integrated Resource Plan (IRP) document. Developed by CEAB, CL&P, UI, DPUC

17. Factors Contributing to Cost Differential

18. COMPARISON OF CL & P vs MIDWESTERN UTILITY (COLUMBUS-SOUTHERN POWER COMPANY) Customer using 750 kWh/month Columbus-Southern Power CompanyCL&P Schedule R-R (Jan 2010) cents/kWh Generation2.7310.50 Transmission and Distribution3.004.74 Other0.602.27 Total6.3317.51 Other for Columbus-Southern is $4.52 customer charge spread over 750 kWh/month Factors causing higher rates in CT: Ohio's generation is 65% from coal which was 25% the cost of natural gas in 2007 (Source:EIA State Electricity Profiles 2008; page 213) RPS adds to CT bills; Ohio has no RPS standard Requirement to build transmission underground (e.g. Middletown-Norwalk) adds cost to Transmission
