RE 2025 CMUA Energy Efficiency Potential Forecasting Study
INTRODUCTION
This memo provides the City of Corona results of the California Municipal Utilities Association (CMUA) Energy Efficiency (EE) Potential Forecasting Study conducted in 2025 by GDS Associates, Inc. (GDS). The results described here are specific to the Corona service territory and account for unique characteristics of the service area, customer base, climate zone, economic conditions, and other relevant factors. This memo provides a summary of the EE Savings Forecast, as well as a description of the data provided in the detailed results spreadsheet file provided to the utility.
SUMMARY OF ENERGY EFFICIENCY POTENTIAL
This potential study provides a roadmap for Corona as they develop strategies and programs for energy efficiency. The development of market potential estimates for a range of feasible measures is useful for program planning and modification purposes.
The Corona energy efficiency program target for the next 10 years (sum of incremental annual, 2026 through 2035) is set at 177 MWh. This results in an average annual target of 0.021 percent of total projected energy sales. Figure 1 provides the market potential for the residential and non-residential sectors, as well as the total incremental potential as a percentage of total sales for the 10-year period of 2026 to 2035.
FIGURE 1. NET INCREMENTAL MARKET POTENTIAL BY SECTOR (MWH) AND PERCENT OF SALES Table 1 below includes the specific inputs used to create Figure 1. The annual energy and demand impacts are provided.
The energy impacts are shown as a percentage of forecasted sector-level and total sales. Incremental annual savings range from 20 MWh to 17 MWh, which corresponds to 0.02% of the forecasted sales.
