1 Electricity Costs over Time APA, 2007, Valdez Steve Colt Institute of Social and Economic Research University of Alaska Anchorage

2 Fundamental Cost Equation Fuel price ($/gal) x Diesel Efficiency (gal/kWhd) = Fuel cost per diesel kWh x Diesel fraction of generation = Fuel cost per overall kWh + Nonfuel cost per kWh = Overall cost of power ($/kWh)

3 Application: all PCE communities

4 Avg real PCE fuel price 2006$/gal

5 times: Efficiency (avg gal/kWh)

6 equals: Avg fuel cost per diesel kWh 2006$ / diesel kWh Fuel price

7 times: diesel fraction of kWh

8 equals: Fuel cost per avg kWh

9 plus: Nonfuel cost per kWh

10 equals: Total cost of power (2006$/kWh)

11 Components of total cost 2006$ per avg PCE kWh

12 Recap: Index values (FY85 = 1.00)

13 What about the Railbelt?

14 Chugach Electric natural gas avg price 2006$/mcf

15 Chugach Electric natural gas efficiency mcf/kWh

16 Chugach Electric avg cost of purch power 2006$/kWh

17 Chugach Electric avg retail revenue 2006$/kWh
