RESOLUTION NO.
A RESOLUTION ESTABLISHING ELECTRIC ENERGY
CURTAILMENT PROCEDURES IN THE CITY OF ASHLAND
AND REPEALING RESOLUTION NO. 77-23.
RECITALS:
A. ORS 757.710 requires any municipality engaged in thE~ sale of
electricity to adopt an electricity curtailment plan for
curtailment of electrical load in the event of prolonged
electrical shortages. The Oregon Public Utility Commission Order
No. 93-084 implements this statute and requires a plan approved
by the commission.
B. The City has a legal responsibility to provide for the health
and safety electric needs of its citizens. In order to minimize
the social and economic impact of electricity shortages, the City
must manage electric supplies prudently.
C. The following resolution implements a prudent manage~ment of
electricity supplies during electricity shortages.
THE CITY OF ASHLAND RESOLVES AS FOLLOWS:
1. Purpose. This resolution identifies the process by which the
City of Ashland will initiate and implement electrical load
curtailment. Detailed procedures are to be followed during a
protracted regional electrical energy shortage to ensure uniform
treatment of all consumers. Curtailment under this resolution 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. Except under
very limited circumstances, curtailment would be activated only
when declared necessary by the State of Oregon.
The purpose of this resolution 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.
2. Definitions. The following words and phrases, whenever used
in this resolution, shall be construed as defined in this
section, unless from context a different meaning is intended.
2.1. "Base Billing Period" means one of the billing periods
comprising the base year.
2.2. "Base Year" means normally, the twelve month period
immediately preceding imposition of State initiated
load/curtailment. The City can use other years if they are more
representative of normal weather conditions.
PAGE I-ELECTRIC CURTAILMENT RESOLUTION (p:ordlelectric.res)(June 24,1993)
2.3. "Billing Period" means that period used by the city
for the reading of electric meters consisting of approximately 30
calendar days.
2.4. "Cooling Degree Day" means a unit, based on
temperature difference and time, used in estimating fuel
consumption and specifying normal annual cooling load of a
building. For anyone day when the mean temperature is greater
than 650 F, there are as many cooling degree days as there are
Fahrenheit degrees difference in temperature between the mean
temperature and 650 F. Cooling degree days (COD) is the sum of
the degree days over a period of time (i.e. day, month, year).
2.5. "critical Load Customer" means a customer that
supplies essential services relating to public health, public
safety, or public welfare.
2.6. "Customer" means any individual, partnership,
corporation, firm, governmental entity or organization supplied
with service at one location and one point of delivery. Service
furnished to a customer at one location through more than one
meter, regardless of rate classifications or schedules, shall be
deemed service to one customer.
2.7. "Current Usage" means the electric energy consumed by
the customer during the most recent billing cycle.
2.8. "Curtailment" means electric load reduction,
irrespective of the means by which that reduction is achieved.
2.9. "Curtailment Target" means the maximum amount of
energy that a customer may use and still remain in compliance
with the resolution; the curtailment target is figured
individually for each customer. The curtailment target may be
weather normalized to reflect the impact of weather on electric
loads.
2.10. "Excessive Usage" means the amount of current usage
less any curtailment percentage declared necessary by the city.
2.11. "Heating Degree Day" means a unit, based on
temperature difference and time, used in estimating fuel
consumption and specifying the nominal annual heating load of a
building. For anyone day, when the mean temperature is less
than 650 F, there are as many degree days as there are Fahrenheit
degree difference in temperature between the mean temperature for
the day and 650 F. Heating degree days (HOD) is the sum of the
degree days over a period of time (i.e. day, month, year).
2.12. "Region" means the states of Washington, Oregon,
Idaho and those portions of Montana that are west of the
continental divide or within the control area of Montana Power
Company.
PAGE 2-ELECTRIC CURTAILMENT RESOLUTION (p:ord\e1e"tric.res)(June24,1993)
2.13. "state" means the Public utility Commission of
Oregon.
2.14. "state initiated" means actions taken by the state to
implement electric load curtailment plans within Oregon.
2.15. "Weather Normalized" means the procedure used to
reflect the impact of weather on electric load levels.
3. Initiation of Load Curtailment. Curtailment shall be
initiated when the state determines that regional deficiencies of
electric energy or capacity necessitate electric load
curtailment. Nothing in this section, however, precludes the
City from initiating curtailment at any time when local
conditions warrant it. Any curtailment action taken by the City
on account of regional deficiencies will be in coordination with
other utility systems in the region.
4. curtailment Staqes. Curtailment shall be requested or
ordered as a percentage of historical base billing period. The
consumption can be weather normalized. The curtailment stages
are associated with increasing energy deficits. The five
curtailment stages are:
Curtailment Target
Staqe # Nature Percent Reduction
stage 1 Voluntary None
stage 2 Voluntary 5%
stage 3 Mandatory 10%
stage 4 Mandatory 15%
stage 5 Mandatory 20%
5. Description of Curtailment Staqes. Upon notification by the
state, the City will initiate stage 1 of this resolution.
5.1. The following restrictions apply during stage 1:
5.1.1. Curtailment of all non-essential uses by the
City itself;
5.1.2. Informing the public of the emergency through
the news media and requesting that all customers voluntarily
curtail all non-essential electricity uses; and
5.1.3. Requesting curtailment of non-essential uses by
governmental agencies and institutions in the city.
5.2. The following restrictions apply during stage 2:
5.2.1. The City will, through the media, suggest the
following specific measures affecting electric energy
consumption:
PAGE 3 - ELECTRIC CURTAILMENT RESOLUTION (p:ordle1ectric.res)(June 24,1993)
5.2.1.1. 650 F maximum thermostat setting for
daytime electric space heating;
5.2.1.2. 550 F maximum thermostat setting for
nighttime electric space heating;
5.2.1.3. 850 F minimum thermostat setting for
electric space cooling;
5.2.1.4. Line drying for clothing;
5.2.1.5. Elimination of:
i. Electric swimming pool heating; and
ii. Outdoor decorative lighting.
5.2.1.6. Elimination of window display, outdoor
display and area, and sign lighting except during nighttime
hours when the place of business is open;
5.2.1.7. Elimination of parking lot lighting
except during nighttime hours when the place of business is
operating, and then only to the levels required for safety
and security; and
5.2.1.8. Elimination of street, public highway
and area lighting not required for safety and security.
5.3. During stage 3 all non-critical load customers shall
meet the curtailment targets specified for stage 3 in section 4.
5.4. During stage 4 all non-critical load customers shall
meet the curtailment targets specified for stage 4 in section 4.
5.5. During stage 5 all non-critical load customers shall
meet the curtailment targets specified for stage 5 in section 4.
6. Weather Normalization. Customers with electric space
conditioning equipment may request the city adjust curtailment
targets to account for differences in weather. curtailment
target adjustment will be accomplished by using Medford weather
data.
6.1. If the current billing periOd'S weather data indicates
that the actual degree days exceeded average base billing degree
days, the customer can request an adjustment to the curtailment
target. The following formulas will be used for this adjustment.
6.1.1. Current usage period actual degree days 7 base
billing period degree days = weather normalization factor.
6.1.2. Base billing period actual consumption x
weather normalization factor = adjusted base billing period
consumption. The following example illustrate this
calculation:
Current usage period actual degree days = 513 HDD
Base billing period actual degree days = 480 HDD
Base billing period actual electric consumption = 3,000 kWh
513 7 480 = 1.07
3,000 x 1.07 = 3,210 kWh
In this example, under stage 3, 10% curtailment requirement,
PAGE 4-ELECTRIC CURTAILMENT RESOLUTION (p;onl\electric.res)(June24,1993)
the curtailment target would be 3,210 kWh x .90 = 2,889 kWh.
6.2. Weather normalization adjustments will be done only if
all of the following occur:
6.2.1.
equipment;
6.2.2.
6 . 2 .3.
severe than
6 . 2 .4.
The customer has electric space conditioning
The customer exceeds the curtailment target;
Weather for current billing period is more
the base billing period; and
The customer requests the adjustment.
7. Critical Load Customer Exemptions. critical load customers,
as set forth below, because of the critical nature of their
operations, will be exempt from mandatory curtailment (stages 3,
4 and 5) requirements once the customer has demonstrated to the
City that all non-essential electrical energy usage has been
eliminated. For the purpose of this resolution, the following
are deemed critical load customers:
7.1. Hospitals, nursing homes, life support systems, and
other health facilities.
7.2. Police and fire stations.
7.3. Essential communication facilities.
7.4. Sewage treatment and pollution control facilities.
7.5. Municipal and public utility water treatment and
pumping installations.
7.6. Any other customers who can demonstrate to the City
that their operations are of a critical nature.
8. Surcharqes for Non-Compliance.
8.1. Any customer who exceeds the curtailment target shall
pay a surcharge as follows:
Violation
Penalty
Stage 3, 4 or 5
$.10 per kWh of excessive usage during
first and second month of excessive
usage.
$.20 per kWh of excessive usage during
third and fourth month of excessive
usage.
$.40 per kWh of excessive usage during
fifth and sixth month of excessive
usage.
PAGE 5- ELECTRIC CURTAILMENT RESOLUTION (p:ord\eledric.res)(June 24,1993)
$.40 per kWh of excessive usage during
seventh and eighth month of excessive
usage plus a one day disconnection.
$.40 per kWh of excessive usage during
ninth and tenth month of excessive usage
plus a two day disconnection.
8.2. During any continuous period of curtailment, assessed
surcharges will continue to be counted for the purposes of
administration of subsequent surcharges, even if there has been
an intervening period of compliance. standard disconnect
criteria and procedures will be used whenever disconnecting
consumers for nonpayment of these surcharges. Health, safety and
welfare considerations will be taken into account, and consumers
will be billed for normal disconnect and reconnect charges.
8.3. Surcharges will be calculated by multiplying the
consumer's excess power consumption each billing period by the
appropriate level identified above.
9. Assessment of Surcharqes.
9.1. Customers will be assessed the surcharges as
prescribed in section 8 for excessive electricity usage.
9.2. The surcharge may be included as a part of the billing
and may be described as "State Mandated." The billing may
include any State provided materials describing the penalty
aspect of the bill. The City may provide its own material to
explain the penalty in lieu of the State supplied material.
9.3. Customers who have applied for a weather normalization
adjustment or an exemption from mandatory curtailment may request
a stay of enforcement of the surcharge pending a final decision
regarding the request.
10. Adjustments and Exemptions to Mandatorv Curtailment Targets.
10.1. Any customer may request adjustment to the
curtailment target based on changes in the customer's facilities
or operation or changes to the customer's residence, family or
living arrangements. A request for an adjustment shall be in
writing and include a brief written description of each change.
The request shall be filed with the Department of Finance.
10.2. Any customer who considers the mandatory curtailment
of this resolution will impose an unusual and excessive hardship,
may apply to the City for relief. This application shall state,
in writing, the reasons such exemption is necessary. Such
request shall be filed with the Department of Finance.
10.3. Adjustment or exemption requests will be investigated
and reviewed and site visits scheduled, if required.
PAGE 6-ELECTRIC CURTAILMENT RESOLUTION (p:ord\e1ectric.res)(June24,1993)
10.3.1. A report shall be submitted to the Ci,ty
Administrator with findings and conclusions resulting from
the investigation and review. The City Administrator shall
approve or deny the request and may impose conditions.
10.3.2. If the City Administrator and the applicant
are unable to reach accord on the request, or if the
applicant is dissatisfied with the City Administrator's
decision, the applicant may appeal to the City Council,
which will make the final determination.
