NO.AVU-G-19-08.
On November 14,2019,Avista Corporation (Avista or the Company)petitioned the
Commission to grant a limited waiver of certain penalty provisions in Schedule 1461 of Avista’s
tariff,and authorize settlement discussions between Clearwater Paper (Clearwater)and Avista to
resolve a disputed penalty that arose from Schedule 146.

under which Avista provided natural gas transportation services to commercial and industrial
customers with requirements exceeding 250,000 therms of gas per year.Under Schedule 146,
Avista may issue an entitlement order prescribing a maximum amount of gas to be used by a
customer per day.Gas used in excess of the prescribed entitlement is subject to an unauthorized
overrun charge.As stated in the Schedule,“the unauthorized overrun charge shall be the greater
of S 1.00 per therm or 150%of the highest midpoint price at Northwest Wyoming Pool,Northwest
south of Green River,Stanfield Oregon,Kern River Opal.El Paso Bondad or Northwest Canadian
border (Sumas)supply pricing points...”(Emphasis added).

The Company petitions the Commission to grant a limited waiver to Schedule 146’s
penalty provisions.Petition at 1.The Company explains it has a contract with Clearwater to
The Commission recently replaced Schedule 146 in Case No.AVU-G-19M5.See Order No.34461.However

DECISION MEMORANDUM 1
provide Clearwater with natural gas transportation.Id.at 2.The terms and conditions in Schedule
146 are incorporated into the contract.Id.
Natural gas prices during the winter of 2018-20 19 were volatile because of the West
Coast Pipeline rupture on October 9,2018.The Company states that,in February and March 2019,
Northwest Pipeline—the main interstate pipeline that transports natural gas from Sumas south
along the 1-5 corridor and east to the Rocky Mountains—issued entitlement notices requiring
shippers on its pipeline to stay within a certain percentage of their nominated natural gas supplies.
Id.at 3.In response to these notices,Avista issued entitlement notices to those customers on its
distribution system that purchase their own natural gas and procure their own natural gas
transportation,of which Cleanvater is one.Id.
The Company states Cleanvater exceeded its nominated natural gas volumes eight
times between February 7,2019 and March 4,2019.Id.Avista issued entitlement penalties for the
eight exceedances,under Schedule 146.Id.As earlier noted,the entitlement penalty in Schedule
146 is calculated by the greater of $1.00 per therm or 150%of the highest midpoint price at one
of a select number of natural gas trading hubs.Id.;see Schedule 146.Avista states that,while the
average natural gas price at various non-Sumas trading hubs during the exceedances was $0.65 per
therm,the average price at Sumas during the same period was S3.59 per therm,with a high price
of S 15.93 per therm.Petition at 3.Avista states the resulting entitlement penalty against Clearwater
is S926,202.Id.at 4.
Avista notes Cleanvater and Avista agree that the entitlement penalty is unduly
burdensome.Id.Avista was never forced to buy more natural gas to make up for excessive natural
gas use by Clearwater.Id Avista notes ‘there was no financial harm to any of Avista’s core
customers,nor was Avista penalized by Northwest Natural.Id.
Avista states Clearwater wishes to engage in settlement negotiations to determine
whether and by what amount the entitlement penalty should be reduced.Id.at 5.Avista notes it
cannot reduce a schedule-derived penalty without the Commission’s authorization.Id.Therefore,
the Company asks the Commission to grant a limited waiver of Schedule 146.Id.If Clearwater
and Avista agree to a modified entitlement penalty,they will jointly file a settlement agreement
with the Commission for approval or rejection.Id.
The Company requests its Petition be processed under Modified Procedure.Id.at 6.
