ln Order No. 93-084, entered January 19, 1993, the Public Utility Commission of Oregon
ordered the Company and other regulated electric utilities operating in the State of Oregon to
adopt the following provisions relating to electric service curtailment during periods of prolonged
energy shortages. The provisions are based on the "Regional Curtailment Plan for Electric
Energy", a plan designed to serve as a guideline for the four Pacific Northwest states to use in
developing their own individual curtailment plans to deal effectively with protracted energy
shortage situations. Such shortages could result from a number of causes such as a prolonged
drought that greatly reduces hydroelectric capability, severe operational constraints that could
reduce hydro capability, a moratorium on the operation of generation plants, or the loss of a
major thermal resource due to mechanical or electrical failure.
Based on the Governor's declaration of an energy emergency pursuant to ORS 176.750
through 176.820, the electric service curtailment provisions call for the Company to implement
measures to encourage Consumers to reduce electric energy use. Possibly included among
measures are the audit of Consumer energy usage quantities, and the implementation of
penalties for exceeding usage guidelines.
l. Purpose and Overview of the Curtailment Plan
This plan identifies the process by which the Company would initiate and implement regional
load curtailment. lncluded in the Plan are detailed procedures to be followed during a
protracted regional electrical energy shortage to ensure uniform treatment of all regional
Consumers. The Plan is not intended to be activated for relatively short-term emergencies such
as those caused by extremely cold weather or the temporary loss of a major generating plant.
The plan would be activated when declared necessary by state authorities.
The goal of this plan is to accomplish curtailment while treating Consumers fairly and equitably,
minimizing adverse impacts from curtailment, complying with existing State laws and
regulations, and providing for smooth, efficient, and effective curtailment administration. The
plan will be implemented in a non-discriminatory manner, without regard to electricity supplier.
ll. Definitions
The following definitions apply to terms used in this Plan.
A. Base Billing Period: One of the billing periods comprising the Base Year. Base Billing
Period data are weather normalized before being used to calculate the amount of
curtailment achieved.
B. Base Year: Normally, the 12-month period immediately preceding imposition of State-
initiated load curtailment.
C. Critical: Load Consumer. A Consumer that supplies essential services relating to
public health, public safety, welfare, or energy production.
D. Curtailment: Load reduction, irrespective of the means by which that reduction is
achieved.

Curtailment Stages
State curtailment directives apply to all retail loads served within the State of Oregon. Under
the Plan, curtailment is requested or ordered as a percentage of historical, weather-normalized
(Base Billing Period) electric energy consumption. The curtailment stages are associated with
increasing energy defi cits.
The five curtailment stages are:
Curtailment Type of
Staqe # Nature Percent Curtailment
Stage 1
Stage 2
Stage 3
Stage 4
Stage 5 Mandatory
lnitiation of Load Curtailment
Load curtailment will be initiated when directed by State authorities. However, nothing
precludes the Company from requesting voluntary load reduction at any time.
A. Overview
Stage-by-Stage Utility Administrative Obligations. Upon notice from the State to initiate
load curtailment, the Company shall immediately begin complying with the directives of
this plan. All requirements for lower level stages continue to apply to higher level
stages. Throughout the curtailment period, the Company will provide Consumers and
ESSs with as much information as possible. The requirements specified below
represent the minimum actions to be taken.
o Staqe 1. The Company will begin (or continue if communication has already begun)
providing curtailment information to Consumers and ESSs. The Company shall also
assist the State, as appropriate, in briefing the media about the shortage.
. Staqe 2. ln Stage 2, the Company will (a) notify Consumers and ESSs of the
percentage level of State-initiated voluntary curtailment; (b) provide curtailment
information to Consumers and ESSs; (c) answer Consumer questions about curtailment;
(d) provide curtailment reports to the States and the Utility Coordinator; and (e) provide
more detailed information to the media than provided in Stage 1.

. Staqe 3: ln Stage 3, the Company will (a) notify Consumers and ESSs of the
percentage level of State-ordered mandatory curtailment; (b) calculate weather-
normalized Base Billing Period data and Curtailment Targets for all Consumers and
ESSs who will be audited in the current billing period; (c) provide Curtailment Targets to
all Consumers and ESSs who request such data for their own accounts; (d) provide
audited Consumers and their ESSs with information about how to apply for exemption
and adjustment of Base Year data; (e) process requests for exemption and Base Year
data adjustments from those Consumers selected for audit who would otherwise be
subject to penalties; and (f) implement the penalties aspect of the Plan.
. Staqe 4: ln Stage 4, the Company will notify Consumers and ESSs of any applicable
changes in State-initiated mandatory curtailment.
. Staqe 5: ln Stage 5, the Company will collaborate with the State to develop and
implement the most effective methods for securing the required load curtailment and to
minimize the economic and human hardships of the last stage of load curtailment.
Suggested Curtailment Actions
lnformation will be disseminated to Consumers and ESSs regarding actions they can
take to reduce their electric energy consumption. The Company will work together with
the State to develop this material. The recommendations will be based on the actions
described in Appendix C of the Plan, 'Curtailment Measurements."
Base Year Data and Curtailment Targets
1. ldentification of the Base Year: The Base Year for a shortage will be established by the
State. Base Year and Base Billing data shall be weather-normalized.
2. Estimating Base Billing Period Data for Consumers for Whom No Base Billing Period
Data Exists: Base Billing Period data must be obtained or developed for any Consumer
who is audited under this Plan. Although residential and General Use Consumers
without actual Base Billing Period data may be excluded from the random sample of
audited Consumers, Base Billing Period data will be estimated for any audited
Consumer for whom actual data does not exist or is found to be inaccurate.
3. Communicating Curtailment Target lnformation to Consumers or ESSs: During
mandatory curtailment, the Company will provide retrospective, current, and
forthcoming billing period Curtailment Target information to any Consumer or ESS who
requests it. The Company will provide retrospective Consumer's ESS upon request. At
the Company's option, it may provide Curtailment Target information to other
Consumers, Consumer classes or ESSs as well.

lnitiation of Load Curtailment (continued)
Auditing Consumers for Compliance with State Orders for Mandatory Load Curtailment. Each
billing period, the Company will audit at least one percent of residential users, five percent of
General Use Consumers, and 100% of Major Use Consumers (including those Major Use
Consumers with estimated Base Billing Period data) plus any Consumers penalized in the
previous billing period. The number of Consumers exempted or excluded from audit will not
affect the sample size.
New samples shall be drawn each month. Consumers penalized under this Plan shall continue
to be audited until their energy use falls below the Threshold Consumption level. Once their
energy use falls below that level, they will be audited again only if selected by random sample.
At its option, the Company may audit 100% of residential users and General Use Consumers.
When auditing less than 100% of members in a class, all such Consumers selected for audit
shall be chosen on a random sample basis, except that the following Consumers are to be
excluded: (a) Consumers granted an exemption under this Plan; and (b) Consumers with an
estimated power bill in the current billing period. The Company may also exclude Consumers
with estimated Base Billing Period data, if the State does not require their inclusion in the pool
of Consumers subject to audit.
Penalties for Non-compliance.1. Nature of Penalties: The penalties under this Plan are structured as follows:
E.
Violation
1 st bimonthly violation
2nd bimonthly violation
3rd bimonthly violation
4th bimonthly violation
5th bimonthly violation
Penaltv
10 cents per kWh of excess use
20 cents per kWh of excess use
40 cents per kWh of excess use
1 day disconnection + 40 cents per kWh of excess use
2 day disconnection + 40 cents per kWh of excess use
6th bimonthly violation Penalties are determined violations by the State. Civil
and all subsequent violations penalties or other corrective actions are possibilities.

Penalties for Non-compliance.
1.
2.
Nature of Penalties: (continued)
The penalty for violators who are billed every two months will escalate on every power
bill in which they are subject to penalty. Consumers billed on a monthly basis will be
assessed the same penalty on two successive occasions before incurring the next
higher level penalty. During any continuous period of curtailment, assessed penalties
remain "on the record" for the purposes of administration of subsequent penalties, even
if there has been an intervening period of "compliance."
Standard disconnect criteria and procedures will be used whenever disconnecting
Consumers in accordance with this Plan. Health, safety, and welfare considerations will
be taken into account, and Consumers will be billed for normal disconnect and
reconnect charges.
Calculation of Financial Penalties: Financial penalties will be calculated by multiplying
the Consumer's Excess Power Consumption each billing period by the appropriate
penalty level identified above.
a. Threshold Consumption Level: The Threshold Consumption level assigned to
each Consumer class is identified in the table below. These values may be
changed by the State.
Type of Consumer
Residential Consumers
General Use Consumers
Major Use Consumers
Threshold Consumption Level
10% above Curtailment Target
10% above Curtailment Target
2o/o above Curtailment Target
b. Excess Power Consumption Calculation: Penalties will not be assessed if a
Consumer's load (either actual load or weather-normalized load) is egual to, or
less than, the Threshold Consumption Level. Excess Power Consumption is
the lower of the following two values for each sampled load subject to penalty:
(a) (Actual Load) minus (Curtailment Target) or (b) (Weather-Normalized Load)
minus (Curtailment Target).

2.Calculation of Financial Penalties: (continued)
Assessment of Penalties:i. Penalties vs. Warnings: Consumers will be assessed penalties only if
they have Excess Power Consumption and if they are to be penalized
based on the penalty assessment procedures described below. Any
sampled Consumer who is not penalized and whose use exceeds the
Curtailment Target will receive a warning.
ii. Penalty Assessment Procedures: The Company will sample at the
mandated minimum percentages for each section as specified in this
plan l1o/o-5o/o-100%l (or as otherwise specified by the State) and
assess penalties on all Consumers with Excess Power Consumption.
At the Company's option, samples may employ higher percentages of
Consumers than the minimums specified above. The Company may
choose among the following penalty assessment options:
(a) Assess penalties on all sampled Consumers with Excess
Power Consumption; (this methodology must be used for Major
Use Consumers even if the Company chooses option (b),
below, for its other Consumer sectors); or
(b) Develop a ratio of the minimum percentage sample size to the
actual percentage sampled for the residential and/or General
Use Consumer sectors. Multiply the resulting percentages by
the total number of violators in each respective Consumer
sector to determine the minimum number of penalties that must
be assessed in each sector. Calculate the percentage violation
for each individual Consumer that has been sampled (Excess
Power Consumption divided by Curtailment Target) and apply
penalties to the "worst offenders" in the overall sample based
on their percentage "Excess Power Consumption." AIso
penalize all Consumers who were penalized in the previous
billing period and who still have the Excess Power
Consumption.
iii. Treatment of DSls: Penalties applicable to BPA's direct-service
industrial Consumers may be assessed by the State based on billing
data provided by BPA. Such penalties and all information requirements
associated with service obtained from BPA will be administered by BPA.
Billing Consumers for Penalties: The Company may describe the penalty on
the power bill as "State-mandated" and shall include any State-provided
material describing the penalty aspect of the plan as a bill stuffer in the bills of
penalized Consumers. The Company shall note on the bill that failure to pay
penalties will result in service disconnection.

Treatment of Penalties Pending AdjustmenUExemption Determinations:
Consumers who have applied for adjustments of Base Billing Period data
and/or exemption from mandatory curtailment may request a stay of
enforcement of the penalty aspect of the Plan pending a final decision
regarding its request. Any Consumer who has been granted such a stay shall
be subject to retroactive penalties as applicable if the request is ultimately
denied.
Use of Funds Collected Under the Penalty Provisions of the Plan: Funds
collected under State-ordered penalty provisibns of this Plan shall be set aside
in a separate account. The ultimate disposition of these funds will be
determined by the Public Utility Commission of Oregon.
Exemptions and Adj ustments
Consumer Application for Exemption/Adjustment: The Company will inform Consumers
of how to apply for exemption from Plan requirements or adjustments of Base Billing
Period data. At its option, the Company may elect to process exemptions and
adjustments only for audited Consumers. Consumers seeking an exemption or
adjustment shall apply first to the Company. lf dissatisfied with the Company's
disposition of an application, the Consumer may apply to the State for exemption or
adjustment.
At its option, the Company may provide for a credit against curtailment for a Consumer
who has accomplished a reduction in demand for service by installing an alternative
energy device, weatherization, or other conservation measures since the base period.
lf savings from these installed measures exceed current curtailment requirements, the
Company may credit the excess against future curtailments.
Granting Consumer Requests for Exemption from Mandatory Curtailment: No
automatic Consumer exemptions will be granted under mandatory State-initiated load
curtailment. The Company will inform exempted Consumers that exemptions may not
protect them from Stage 5 black-outs.
a. Critical Load Consumers: Critical Load Consumers must demonstrate to the
Company that they have eliminated all non-essential energy use and are using
any reliable, cost-effective back-up energy resources before the Company will
exempt them.
b. Other Consumers: Exemptions for Consumers not qualifying as Critical Load
Consumers under this Plan will be evaluated based on whether curtailment
would result in unreasonable exposure to health or safety hazards, seriously
impair the welfare of the affected Consumer, cause extreme economic hardship
relative to the amount of energy saved, or produce counterproductive results.
Utility Record-Keeping Relative to Consumer Exemptions: Records regarding
exemption determinations will be made available to the Commission upon request.

Measurement of the Amount of Curtailment Achieved and Determination of Compliance
At all times during State-initiated regional load curtailment, the Commission and the Utility
Coordinator will be provided with consumption and savings data on a monthly basis in the form
specified in Appendix D of the Regional Plan. To the extent that circumstances at the time of
actual load curtailment dictate the need for additional data or more frequent data submittal, a
best effort to comply with the Commission request will be made.
Special Arrangements
1. Use of Consumer-Owned Generation Facilities: Consistent with the need for safety and
system protection, Consumers having their own generation facilities or access to
electricity from non-utility power sources may use energy from those other sources to
supplement their curtailed power purchases from the Company.
2. Curtailment Scheduling: During periods of mandatory curtailment, a Consumer must
provide the required amount of curtailment within each billing period. Within that period,
and subject to equipment limitations and rules on load fluctuations, Consumers are freeto schedule curtailment so as to minimize the economic cost, hardship, or
inconvenience they experience as a result of the mandatory curtailment requirement.
Appendices and Related Gurtailment lnformation
The Regional Electric Energy Curtailment Plan is available for review in each of the
Company's local offices. That plan contains additional information on curtailment
administration.
