- B.1 INTRODUCTION

For furnace fans

, the Department of Energy ( DOE ) developed monthly energy price

factors and used monthly energy consumption data for the l ife

- c ycle c ost and p ayback p eriod

calculations. DOE developed monthly energy price factors to capture robust seasonal trends in

monthly energy prices

. Figure 8

- B.1.1 depicts the monthly energy price factor calculation

process.

CALCULATIONS

DOE collected historical natural gas prices from 19 89 to 2010 from the Energy

Inform ation Administration’s ( EIA’s ) Natural Gas Navigator. 1 

### The Natural Gas Navigator

includes annual and monthly natural gas prices for residential, commercial, and industrial

consumers by State. DOE aggregated the data into 29 geographical areas described in Chapter 8

(section 8.2.2.2 Energy Prices)

.

For each geographic area , DOE determined average natural gas prices from 19 89 to 2010

by weighting the average residential natural gas prices for each State by the number households

projected in 2018 in each state

- B.3 MONTHLY RESIDENTIAL ELECTRICITY PRICE FA CTOR

CALCULATIONS

DOE collected historical electricity prices from 1990 to 20 10 from EIA’s Form 826. 2



### These data are published annually and include annual electricity sales, revenues from electricity

sales, and average price for the residential, commercial, industrial, and transportation sectors by

State. DOE aggregated the data into 29 geographical areas described in Chapter 8 (section

8.2.2.2 Energy Prices)

.

For each geographic region, DOE determined average electricity prices from 1990 to

20 10 by weighting the average residential electricity prices for each State by the number

households projected in 2018 in each state

. Table 8

- B.3.1 shows the results for California

DOE then averaged the monthly energy price factors for 1995 to 2009 to develop an

average energy price factor for each month. DOE performed the same calculations for each

Census R egion to develop the average monthly energy price factors shown in Table 8

### DOE then applied the regional monthly energy price factors to the annual oil data

presented in chapter 8 to develop monthly energy prices for 2 0 10 ( Table 8

- B.5.4 ). Each Census

Division and Large State was matched with the appropriate Census Region.
