REQUEST:
Please provide the avoided cost calculations the Company used to determine that natural gas
demand-side management is not cost-effective for Idaho. Please provide and explain the
assumptions used.
RESPONSE:
See Staff PR_2 Attachment A containing the avoided cost stream used in the original analysis of
the viability of a cost-effective natural gas demand-side management portfolio in Idaho. These
avoided costs were the product of the then in-progress lntegrated Resource Plan process. Given
the dramatic change in the avoided cost the Company sought to complete the analysis of the
demand-side management portfolio and communicate them to external parties in a timely manner.

REQUEST:
Did the Company assume any avoided distribution, transportation or storage related costs in its
avoided-cost calculation? Please explain why or why not.
RESPONSE:
The Company did assume avoided transportation and storage related costs in the avoided-cost
calculation, as those are the costs that would be avoided through incremental DSM. The
SENDOUT@ model-determined avoided-cost represents the unit cost to serve the next unit of
demand with a supply-side resource option during a given period. If a conservation measures total
resource cost (for Idaho and Oregon), or utility cost (for Washington), is less than this avoided
cost, it will be cost effective to reduce customer demand and Avista can avoid commodity, storage,
transportation and other supply resource costs. Distribution costs, however, are localized in nature
and are therefore managed at an operational level. For example, while a DSM measure would
avoid incremental supply costs, there wouldn't necessarily be avoided distribution costs as the
distribution system is already in place. As such they are not incorporated into the avoided cost
calculation.
