17 Delmarva Estimated Program Costs

18 Pepco and Delmarva Estimated Annual Program Costs Column Descriptions
(A) Installed costs for outside switches and programmable thermostats (B) Marketing expenses (includes one-time participant enrollment) (C) Contracted services, such as installation management and scheduling, quality assurance, and any warranty issues (D) Estimated monthly bill credits (E) Administrative costs (F) Maintenance costs associated with installed switches and thermostats (G) Measurement, verification and program evaluation costs (H) Total yearly program costs

19 Participant Financial Incentives
Enrollment/Installation Incentive Rapid enrollment - Critical to this Demand Resource Program, a One Time Installment Enrollment credit will be paid per direct load control device. In exchange for the above credit, a participant will have to stay enrolled in the program for a minimum of one year. Annual Incentive Minimize Attrition, The Annual Fixed Credit is geared to reward those participants who stay with the program for many years. The Annual Credits will be paid over the June through October billing months. Annual Fixed Credit will be adjusted to reflect 70% of projected capacity market value each year. Participants will be notified in the spring of each year. All financial incentives will be in the form of a utility bill credit to the participants electric service account.

21 RIDER “R-DLC” General Provisions
1. A smart thermostat(s) or radio controlled switch(es) and associated equipment will be installed on the residential customer's central air conditioner or central heat pump equipment for the purpose of cycling control as described below. 2. Customer may select one of the following three demand response options: RESIDENTIAL DLC-50% CYCLING - Whereby a participating residential customer’s air conditioner compressor will be cycled off for 15 minutes of each half hour period. RESIDENTIAL DLC-75% CYCLING - Air conditioner compressor cycled off for 22.5 minutes of each half hour period. RESIDENTIAL DLC-100% CYCLING - Air conditioner compressor cycled off completely during each half hour period.

22 RIDER “R-DLC”- Continued
3. The Company may exercise cycling control for the following reasons: 1) test cycling equipment, 2) response to a PJM dispatcher request to activate the program, 3) response to local DPL electric system constraints, or 4) response to regional energy market prices. Participant override of cycling events will be limited to two events annually and are not permitted during PJM initiated cycling events.

23 RIDER “R-DLC”- Bill Credits
4. The customer will receive the following applicable bill credits while participating in the program. The Annual Fixed Credit is paid proportionally during the June through October billing months. In exchange for the One Time Installment Credit, participants will be required to remain enrolled in the program option for a minimum of one year.

DLC-50% DLC-75% DLC-100% One Time Enrollment Installment Credit $40.00 $60.00 $80.00 Annual Fixed Credit 70% of Capacity Market Value Minimum

25 PJM Market Participation
Capacity PJM Forward Market Interruptible Load for Reliability (“ILR”) Market Bilateral RPM Base Residual Auction (BRA) occurs three years prior to delivery Energy – Day Ahead/Real Time Location Marginal Pricing (LMP)

26 PJM Capacity Earnings Earnings Assumptions:
96 percent of projected participant program capacity, 75 percent bid into the forward RPM BRA capacity market, 25 percent bid into the PJM ILR market, Based on recent PJM regional prices. Pepco Calculation Example {[(206 MW)*(75%)*($174.29)*(365)] + [(206 MW)*(25%)*($140.16)*(365)]}*(96% DR Availability) Delmarva Calculation Example {[(67 MW)*(75%)*($178.57)*(365)] + [(67MW)*(25%)*($177.51)*(365)]}* (96% DR Availability)

27 Cost-Effectiveness Measure Impact Estimation
Demand response savings for each of the measures identified are based upon the Lawrence Berkeley National Laboratory Study, as described in the Company’s February 15, 2008 filing. Annual Energy Savings for Smart Thermostats: The baseline building definitions and each individual DSM measure were entered into the DOE2.1E energy simulation modeling program. Program Cost Estimation Projected program cost estimates were based upon currently available pricing data and projected customer participation levels. Actual program costs will vary depending upon actual customer participation levels and vendor pricing.

28 Cost-Effectiveness (continued)
Market Potential Estimation Market potential estimates used in the analysis were projected based upon the Company’s historic residential cycling penetration rates. Estimated savings of 325KWh from the programmable thermostat.

29 Cost-Effectiveness (continued)
Cost-Effectiveness Screening Program-level calculation of cost-effectiveness was completed for four tests – the Societal Cost Test, the All Ratepayers Test (Total Resource Cost Test), the Ratepayer Impact Measure Test, and the Participants Cost Test. These tests include consideration of program administrator costs, incentive levels, incremental costs, and measure impacts.

30 Cost-Effectiveness (continued)
For all tests, cost-effectiveness was calculated using the lifetime impacts of first-year installations. All benefit and cost components used in these tests are proportional to the number of installations. Using first-year installations produces cost-effectiveness values that are considered representative of all years.

31 Four Cost-Effectiveness Tests
The Societal Cost Test (SCT) is identical to the All Ratepayers Test used in the past, except that the SCT accounts for externalities and uses a different societal (discount) rate. The All Ratepayers Test compares the total costs of the program, including participant and utility costs, to the total benefits, excluding the effect of externalities. The Rate Impact Measure Test compares demand side program impacts on electricity rates due to changes in utility revenue and program costs to the costs that are avoided. The Participant Test compares the benefits and costs for program participants and serves as a guide for program design.
