TABLE 1. Updated Natural Gas Long-Run Forecast

(Nominal $/MMBTU)*

* Gray area from 2006 through 2011 is not used in computation of avoided costs, gas futures data from NYMEX is used through 2011. Shaded area from 2012 to 2014 is the transition period. During the transition period, the natural gas forecast is a blend of NYMEX futures and the Long-Run gas forecast.

The current E3 methodology uses an average of the EIA, CEC and SoCalGas forecasts as the input stream for calculating electric generation avoided costs. This table shows the long-run (also referred to as "fundamental") gas price forecasts based on an average of these updated forecasts. Note that only the values in 2015 and later are used in either gas or electric avoided cost calculations. ¹

The SoCalGas 4/2/04 forecast was originally provided as inputs to the 2004 California Gas Report. It was subsequently used in the 2004 Market Price Referent (MPR) Staff Report as one of several natural gas price forecasts that were averaged together. In April 2005, parties agreed to use the three non-proprietary fundamental gas price forecasts from the MPR staff report as inputs to the E3 avoided cost update. In February 2006, parties agreed that the EIA and CEC fundamental gas price forecasts should be updated. SoCal Gas informed parties at the February workshop that an update to their forecast was not available. The updates to the CEC and EIA forecasts are described in the Final Report, on pages 36-37.

This is a combination of market forwards in 20067 and 2007, then long-run marginal cost (LRMC) of a combined cycle combustion turbine (CCGT) in years 2008 onward. The CCGT LRMC uses the natural gas prices from Table 3.

Table 5. Natural Gas Avoided Costs (commodity and environmental) for Gas Energy Efficiency Measures

1. The natural gas avoided costs vary by month. This variation is not needed for calculating an annual average LRMC for a CCGT, but it does matter for gas efficiency measures.

2. The natural gas avoided costs vary by the type of combustion device being affected. Different devices will have different air emissions for the same therm of natural gas input. This results in slightly different environmental costs for the different devices. Tt is assumed that residential measures reduce emissions that are consistent with a furnace, and commercial customers reduce emissions that are consistent with a small boiler that does not have emission controls installed. (These assumptions have been in place since the marginal costs were produced for energy efficiency evaluation in April 2005).

These avoided costs start with the values in Table 2, apply the monthly price shape exhibited by the NYMEX data, adjust for losses and unaccounted for, and then add on the environmental costs (based on furnace or small boiler emission rates).

Like electricity avoided costs, gas T&D avoided costs remain unchanged. The gas T&D avoided costs can be found in Tables 32 and 33 on page 138 of E3's October 25, 2004 Methodology and Forecast report.
