Notes:

                       

(1) Total annual energy savings = all savings from energy efficiency programs funded by public goods charge and Procurement funding.

This total includes savings from baseline Energy efficiency program funding of $100 MM/yr accounted for in the CEC sales forecast.

For incremental program savings above the levels included in the CEC forecast, see attached workpapers.

     

(2) Average peak MW estimated by multiplying GWh from utility by the ratio they used in 2004/5 filings ranges from .19 to .21.

 

This is an estimate of average peak savings not coincident peak = GWh savings in peak period/560 hours in period.

   

2013 goal as a % Xenergy estimate of maximum achievable = 90.9%

   

Staff 2013 goal as a % of Xenergy estimate of economic potential = 67.9%

   

Econ potential for 3 IOUs (GWH/yr) = 34,133

   

Max achievable potential for 3 IOUs (GWH/yr) = 25,490

This total includes savings from baseline Energy efficiency program funding of $100 MM/yr accounted for in the CEC sales forecast.

For incremental program savings above the levels included in the CEC forecast see attached workpapers.

(2) GWh Savings converted to MW by multiplying by .217, which is ratio of GWh to peak savings for 2004/5 applications

This is an estimate of average peak savings not coincident peak = GWh savings in peak period/ # of hours in period = 560 hours

Total savings = all savings from energy efficiency programs funded by public goods charge and Procurement funding.

 

This total includes natural gas savings from Energy efficiency programs already included in the CEC forecast.

   

                             

These natural gas savings goals do not include any incidental gas savings caused by SCE's electricity programs.

 

These gas savings are reported by SCE for resource planning purposes.

Notes:

                   

SoCalGas' cumulative goal (230 MW) is approximately 52% of total savings, or proportional to SoCalGas' share of natural gas sales,

which are estimated at (less gas used as a feedstock) roughly 52% of 2003 statewide sales. (Source: CEC 2002 Natural Gas Forecast)

The analysis uses a 1% degradation, year over year, in the assumed effectiveness of programs post 2006.
