1. Unpacking the equation -- What are the inputs that impact TRC and what program design elements have the largest impact?
2. How CPUC cost-effectiveness policy has impacted successful energy efficiency programs?
3. Why are certain programs refunded while others don’t make the cut?
4. How do non-resource programs serve to improve the performance of energy efficiency resource programs?
5. What are some other options to measure cost-effectiveness?

TRC = Total Resource Cost Test
What is “Cost-Effective?”
Benefits
Costs≥ 1
What counts as a “Benefit”?
What counts as a “Cost”?
Who is receiving the costs & benefits?

The Southern California Regional Energy Network (SoCalREN) was created to harness the collective power of residents, businesses and the public sector to achieve an
unprecedented level of energy savings across Southern California.
The SoCalREN Public Agency Programs are administered by the County of Los Angeles and funded by California utility ratepayers under the auspices of the California Public Utilities Commission. Learn more at socalren.org.

Overview: Energy Efficiency Cost Effectiveness
1. How is cost-effectiveness measured?2. What is Total Resource Cost?3. How is avoided cost determined?4. Is TRC for everyone?

How is Cost-Effectiveness Measured?Test Question Answered
Total Resource Cost (TRC) Will the sum of the utility’s total costs and the participant’s total costs decrease?
Participant Cost Test (PCT) Will costs decrease for program participants?
Ratepayer Impact Measure (RIM) Will utility rates decrease?
Program Administrator Cost Test (PAC)
Will the program administrator’s total costs decrease?
Societal Cost Test (SCT) Will total costs to society decrease?

How are Avoided Costs Determined?Input Definition
Cost Factors Costs avoided by the utility due to reduced energy consumption/demand
Energy Savings (kWh/therms) Utility-recognized measure savings
Effective Useful Life (EUL) Useful life of the measure installed
Discount Rate (%) Accounts for time value of money
Gross Realization Rate (GRR) Accounts for potential overestimation of savings
Net-to-Gross Ratio (NTG) Accounts for “free riders” in the program
