REQTJEST:
Please explain how the Company assures that costs and physical delivery of natural gas to each
state are properly tracked and recorded.
RESPONSE:
Please see the Company's response to Staff_PR_004 for additional information regarding how
purchases and sales axe procured for both the Local Distribution Company (LDC) and electric
power supply ("Power Supply") for generation needs.
Avista's Energy Resources group purchases natural gas in both the forward and spot markets for
delivery to local distibution company (LDC) customers and to optimize unused pipeline capacity.
The LDC and Power Supply each maintain separate, directly assigned frm transportation rights
on several different pipelines. Forward purchases are typically directly assigned based on
Procurement Plan for the LDC, or anticipated needs for our power supply electric generation. [n
the spot market, often deals are transacted on a total Company basis. In this instance, costs are
assigned based on the amount of natural gas scheduled to flow either to serye customer load in one
of Avista's LDC jurisdictions or for electric power generation. Should there be open transportation
capacity and it makes economic sense to do so, the Company will enter into wholesale transaction
providing optimization revenue to benefit customers. Schedules are created from pipeline
nominations in Avista's tuading system, Nucleus, that track where the purchased natural gas was
delivered. Each jurisdiction is assigned the cost of the volume of purchased natural gas that was
delivered to that jurisdiction from each market hub. tn the spot market often purchases are
combined, and an after-the-fact calculation is performed within nucleus to confirm each
jurisdiction is assigned the appropriate amount of commodity costs and benefits based on load and
transportation capacity. The Company is very diligent in tracking costs in order to appropriately
assigned to individual jurisdictions (Washington/Idaho, Oregon, or Electric Power Generation).
Due to the interconnected nature and close proximity of our Washington and Idaho customers,
costs are assigned 6(AN" (Allocated North) and in the accounting close process they are separated
to each State's customers based specific Commodity Volumes for that month.

WITNESS: N/A
RESPONDER: Justin Dorr
DEPARTMENT: Energy Resources
TELEPHONE: [phone]
REQUEST:
Please explain the criteria used to determine pipeline capacity releases and how they are allocated
between jurisdictions.
RESPONSE:
Avista, under state commission guidance and as supported by the Integrated Resource Plan, is
required to hold enough firm pipeline transportation to serve core customers on a peak day. Since
Avista's transportation load requirements vary so much throughout the year, Avista finds itself
with excess capacity across its service territory. Avista historically has sought to optimize its
transportation portfolio by releasing capacity to third parties. All capacity release revenue is
credited back 100% to our customers. Avista will analyze each capacity release request to ensure
we can continue to serve all core customers on a peak day. Avista, as a rule, will not release
transportation capacity if it degrades firm service to core customers, or if it creates additional
exposure to higher priced commodity markets.
Capacity release revenue is recorded as a reduction to total tansportation costs in the same manner
as transportation contacts. Capacity release revenue is split and recorded between Washington
and Idaho based on the 5-day peak ratio.
