TO: Michael C. Van Milligen, City Manager

SUBJECT: Alliant Energy Interruptible Service Contract Renewal 2019 - 2022
DATE: May29, 2019
INTRODUCTION
The purpose of this memorandum is to request the City's continued participation in Alliant
Energy's Electric Interruptible program. Execution of the attached agreement between the City
and Alliant Energy, for electric service to the Eagle Point Water Treatment Plant, will ensure
continued participation June 1, 2019 through April 30, 2022.
BACKGROUND
The City of Dubuque Eagle Point Water Plant is currently a participant in Alliant Energy's Electric
Interruptible Program. The program offers, in exchange for reducing consumption during periods
of extreme demand, a discount on electric pricing for the year. The program is suitable for the
water treatment plant as the plant has the ability to curtail a minimum of 200 kW during extreme
electric load, by switching to generator power supply.
During 2018, the Eagle Point Water Plant was asked to curtail electric service in August, and was
subject to a test in June. In 2017, service was interrupted in July and tested in May. During these
periods the City's water treatment plant was under generator power at no loss of supply to the
City's customers. The credit program offers significant savings to the City without disruption to the
City's drinking water supply.
DISCUSSION
The proposed agreement does include some changes to the interrupt program which include:
• Credit levels; summer level of $5.37/kW and winter level of $3.46/kW. These credits are
lower than the current credit levels which are $7.06/kW for summer and $4.55/kW during
the winter period.
• Three year contracts; testing occurring only once every 3 years if no events are called.
• For economic condition interrupts, there will be unlimited buy-throughs. This would permit
the City to decline interruptible service buy through the event.
• Firm levels can only be increased by 20% annually(average peak load minus current firm
kW level times 20%) and only 30% for the life of the contract. The pumping increase to
the Roosevelt Tower would be lower than the percentage increase, and therefore not
impact the credit available to the City.
The contracts were reviewed by Barry Lindahl, Senior Legal Counsel. Mr. Lindahl approved the
contrects and they are ready for the City Manager's signature. Mr. Lindahl advised the item should
be placed on the Council Consent Agenda under "Contrects Signed" following execution of the
agreement.
BUDGETIMPACT
The program is a credit program, with credits issued to the City on a monthly basis itemized on
the monthly bill. Savings credited to the City for Year 2018 were $65,218.07 The projected
savings to the City under the new agreement would be $49,599 on average, per year.
REQUESTED ACTION
I respectfully request execution of the attached agreemeM between the City and Alliant Energy,
for Interruptible electric service, at the stipulated credit fee structure, to the Eagle Point Water
Treatment Plant starting June 1, 2019 through April 30, 2022.

conditions that Company will follow when deciding whether to enact an interruptioa Condition 1 is driven by
relia6ility wnsiderations, and conditions 2 and 3 are based on energy eNiciency as defined by the lowa Utilities
Board. Condition 2 is designed to reduce peak demand, and condition 3 is designed to reduce energy usage.
Company shall interrupt if it is anticipated that any one of following four conditions exists:
(1) Reliability: Interruptions are necessary to maintain safe and reliable system operations and meet
obligalions to other interconnected systems.
(2) Energy Efficiency—Reducing Peak Demand: Company would expect to experience less than planning
reserve margin for the current year, where (i) planning reserve margin is defined as the amoun[ 6y which
capacity resources exceed Customer firm demand expressed as a percent of Customer firm demand, and
(ii) Customer firm demand is defined as the load forecast of firm demantl assuming normal (or 50-50)
summer peak weather.

(3) Energy Efficiency—Reducing Energy Usage: The dayahead locational marginal price (�MP) for
Company's load zone in [he Midwest Independent Transmission Sys[em Operator, Inc (MISO) footprint is
at the "iunning on oil" level for at least four consecutive hours or the rolling four-hour average real-time
LMP for Company's load zone exceeds [he "running on oil" level, where the "running on oil" level is a
pretletermined LMP defned by an assumed heat rate of 13.5 million Btu per MWH and a spot market price
for No. 2 oil.
(4) Program Quality Control: Reasonable interrup[ions are necessary to test lhe capabilities of Customers. If
there are no interrup[ions for conditions 1, 2 or 3 in a year by August 1, then Company will conduct a test
interruption of all Customers. The test will be conducted by Company behveen Augus[ 1 antl September
16 under circumstances as close as possible to a condition 2 or condition 3 inte«uption. Additionally,
Company retains the premgative to contluct a test of any Customer at any time of the year if it determines
in its sound discretion that such a test is necessary to preserve the integrity of the progrem.
Interruption Buy-Through:
In the event a Customer is notified to cudail for conditions 2 or 3 of the interruptible program decision rule,
Customer can elect to buy through the period of curtailment and 6e in compliance with the Interruptible Service
Penalty of this rider. The buy-through cost will be computed as each hourly kW priced at the ALTW.ALTW node
real-[ime LMP price plus a 12% adder for any incremental administrative and MISO-related charges, less the
energy adjustment clause factor for the month. The 12% adder will be applied for the first year and then revised
annually as needed to reflect expected MISO-related costs and administrative and regulatory costs associated
with a Customer's buy-through election. A Customer can elect to buy-through M✓o events annually if ten or fewer
wrtailmen[s and three events if more than ten curtailments are called, where Ihe annual period is the Load Year
starting May 1. Customers who utilize the Interrupti6le Balancing Pool Option shall opt to buy Ihrough a total N
annual kW amount computed as lwice its "total interruptible forecast load" and buy-throughs shall be tracked by N
kWs bought through instead of number of buy-through even[s. All other billing provisions apply. N
In[erruptible Non-compliance Penalty:
Customer is deemed to have failed to interrupt if it imposes load on Ihe system that exceeds its contract firm
demand during the period when it has been instructed to interrupt and (1) it has not requested a buy-thmugh or
(2) it has requested a buy-through but it has exhausted its buy-through opportunities. Company shall have the
ability to not penalize Customer for less than full compliance with a notice of in[erruption where in Company's
sound discre[ion the load difference is from malfunction of Company's communication equipment or Company's
communication breakdown and is not the resWt of Cusromer's indifference or intentional disregard of the notice
of curtailment and Customer has a history of full compliance. In such cases Cus[omer shall neveRheless
reimburse the utility for any additional costs that result. Company will continue its practice of documenting any
such waiving of penalties, including all relevant circumstances. The penalties that will be imposed on Customer
for faiWre to interrupt in addition to Ihe charges billed accortling to Ihe underlying tariff are the following:
For The First Penalty Instance�.
(1) Upon notice from Company to interrupt, Customer decides whether to comply with the request, exercise a
buy-through option if available or be subject to a non-compliance penalty for a failure to pedorm. Company
will not assume Customer has bought through if there is excess kW ovei the firm contrect demand and a
buy-through is available, but rather will only log and bill a buy-Ihrough upon explicit instructions from
Customer. If Customer has advised Company of its inten[ to interrupt but fails to fully compty, then
Customer must notify Company within one hour of Ihe failure to comply ot Customer's eleclion to use an
available buy-through.
(2) Customer will be levied a one-time fee of $2627 per kW for each excess kW over the firm contract
demand.
(3) Cuslomer will be billed for any energy (kWh) received during an interruption period above its contract
amount at the buy-through wst as definetl in the buy-through provision of Company's interruptible tariff.

(4) Customer's contract firm demand will be set at the highest level experienced during the period of the failure
to interrupt and will remain at that level for twelve months, except tha[ Customer will have one opportunity to
requalify for a lower level after six months if Customer demonstretes that the non-compliance was
unintentional, not the result of Customer negligence and upon consideration of all relevant circumstances is
judged not likely [o recur. Customer can requalify for a lower level once it notifies Company of its readiness
to be interruptetl at its proposetl contract firm demand and i[ successfully completes a test interruption
called by Company, if Company in its sound discretion deems [hat a test is necessary. Company will
conduc[ the test interruption to simulate to the maximum extent practicable the circumstances of a typical
interruption and in no event shall the test interruption be more than 30 days aker Customer's reatliness
notification.
For Penalty Instances in Subsequent Months antl Within Twelve Months of the First Penalty.
The above provisions associated with the first penalty instance will apply except that (1) the one-time fee levietl
on each excess kW over the contrect demand will be twice the amount applied for the first penalty and (2)
Customer cannot qualify for a lower contract firm level until twelve months after this subsequent penalty.
Discounts:
Discounts for power factor antl voltage level are definetl in the LGS tariff.
Additional Terms and Contlitions:
1. Inte«uptions resulting from conditions 2, 3 and 4 for the typical (average) Customer will not exceed
64 hours annually. For purposes of determining the number of hours of interruption under the annual
64-hour limit. each interrup[ion will be deemed to have occurred for Fhe greater of four hours or the
actual duration of the interruption.
2 For purposes of determining the number of hours of buy-through under the annual two event limit
and the annual three event limit of the buy-Ihmugh section that applies towards the 64-hour limit,
each buy-Ihrough will be deemed to have occurred for the grealer of four hours or the actual duration
of the interruption event.
3. A monthly interruptible cost recovery charge of $3079 shall apply for each account contracting for R
interruptible service under [his rider. This charge shall appty to incremental interruptible expenses
not contemporaneousty recovered Ihrough the EECR factors in Rider EECR.
4 The program employs a three-level system status classification. The three levels are defined as
follows:
a. System NormaL This is the state of the program in most hours of the year.
b. Warning. This is the state in which an interruption can 6e called at any time. Company will
send a message announcing the warning via its Power Manager sys[em. The waming will
be sent by Company as soon as Company de[ermines that events warrant a change from a
normal sta[us to a waming status.
c. Interruption. The system is experiencing an interruption in this slate. An interruption can
occur without Ihe issuance of a waming.
5. For interruptions invoked untler conditions 2, 3 and 4, the shortest amount of time between the time
when Customer is notified that it has to be in interruptible compliance antl the time when it must be
in compliance to avoid a penalty will be two hours. For interruptions invoked under condi[ion 1
(reliability), Customer may be asked to interrupt immediatety and will be expected to make its best
efforts to comply immediately if asked to interrupt immediately. Under condition 1 interruptions, non-
compliance penalties will not be assessed for Customer behavior within the two hour period from the
time when Customer is called to inferrupt.

Board. Condition 2 is designed to reduce peak demand, and condition 3 is designed to reduce energy usage.
Company shall interrupt if i[is anticipated that any one of following four conditions exists:
(1) Relia6ility: Interruptions are necessary to maintain safe and reliable system operations and meet
obligations to other interconnected systems.
(2) Energy Efficiency - Reducing Peak Demand: Company would expect to experience less than MISO

ALiW.ALTW load zone is based upon the Company's highest cost resource for at least four consecutive C
hours or [he rolling four-hour average real-time LMP for ALTWALTW load zone exceeds the Company's C
highest cost resource. IPL will define a pre-determined LMP annually based upon the highest cost C
resource of IPL's current generation resource portfolio and its associated fuel costs. p
(4) Program Qualiry Control: Reasonable interruptions are necessary to test the capabilities of Customers. If C
there are no interruptions for conditions 1, 2 or 3 after the second year of a Customer's three year C
contract, as well as no interruption in ihe third year by August 1, Company will conduct a test interruption C
of Customer. The test will be conducted in the third year of the Customer's contract by Company C
between August i and Sepfember 16 under circumstances as dose as possible to a wndition 2 or
condition 3 intermption. Additionally Company retains the prerogative to conduct a test of any Customer
at any time of the year if it determines in its sound discretion that such a test is necessary to preserve the
integrity of the program.
Interruption Buy-Through:
In the event a Customer is notified to curtail for conditions 2 or 3 of the interruptible program decision rule,
Customer can elect to buy ihmugh the period of cuM1ailment and be in compliance with the Interruptible Service
Penalty of this rider. The buy-through wst will be computed as each hourly kW priced at the MISO C
ALTW.ALNV node real-time LMP price plus a 10% adder for any incremental administrative and MISO-related C
charges, less the energy adjustment clause factor for the month. All other billing provisions apply. �
Interruptible Non-compliance Penalty:
Customer is deemed lo have failed to interrupt if it imposes load on the system Ihat exceeds its contract firm
demand during the period when it has been instructed to interrupt and it has not requested a buy-through for the C
event when provided the opportunity to buy-through. Company shall have the abiliry to not penalize Customer C
for less than full compliance with a notice of interruption where in Company's sound discretion the load
difference is from malfunction of Company's communication equipment or Company's communication
breakdown and is not the resWt of Customer's indifference or intentional disregard of the notice of curtailment
and Customer has a history of full compliance. In such cases Customer shall nevertheless reimburse [he utility
for any additional costs that result Company will continue its practice of documenting any such waiving of
penalties, including all relevant circumstances. The penalties that will be imposed on Customer for failure to
interrupt in addition to ihe charges billed according to the undertying tariff are the following:
Por The First Penalty Instance�
(1) Upon notice from Company m interrupt, Customer decides whether ro comply with the request, exercise a
buy-through option if available or be subject to a non-compliance penalry for a failure to perform.
Company will not assume Customer has bought through if Customer's load exceeds Iheir firm contract C
demand and a buy-Ihrough is available, but rather will only log and bill a buy-through upon explicit
election of buy through by Customer. If Customer has advised Company of its intent to intermpt but fails C
to fully comply, Ihen Cusromer must notify Company within one hour of ihe failure to comply of
Customer's election to use an available buy-through.
(2) Customer will be levied a one-time fee of $2627 per kW for each excess kW over the firm contract
demand.
(3) Customer will be billed for any energy (kWh) received during an interruption period above its contract
amount at the 6uy-through cost as defined in the buy-thmugh provision of Company's interruptible tariff.

failure to interrupt and will remain at Ihat level for the remainder of iheir contract term, except thai C
Customer will have one opportunity to requalify for a lower level after six months if Customer
demonstrates Ihat the non-compliance was unintentional, not the result of Customer negligence and upon
consideration of all relevant circumstances is judged not likely ro recur. Custamer can requalify for a
lower level once it notifies Company of its readiness to be interrupted at its proposed wntract firm
demand and it successfully completes a test intermption called by Company, if Company in its sound
discretion deems that a test is necessary. Company will conduct the test interruption to simulate [o Ihe
maximum extent practicable the circumstances of a typical interruption and in no event shall the test
inlerruption be more than 30 days after Customer's readiness nolifiwtion.
For Penalry Instances in Subsequent Months and Within Twelve Months of the First Penalty:
The above provisions associated with the first penalty instance will apply except that(1) the one-time tee levied
on each excess kW over the contract demand will be twice the amount applied for the first penalty and (2)
Customer cannot qualify for a lower contract firm level until twelve monihs after ihis subsequent penalry.
Discounts:
Discounts for power factor and voltage level are defined in ihe applicable tariff. C
Additional Terms and Conditions:
D
(1) A monthly interruptible cost recovery charge of $5.67 shall apply for each account contrecting for R
intermptible service under (his rider. This charge shall apply to incremental interruptible expenses

(2) The program employs a three-level system status classification. The Ihree levels are defined as
follows:
a) System Normal. This is tM1e state of the program in most hours of ihe year.
b) Warning. This is the state in which an interruption can be called at any time. Company will
send a message announcing lhe waming via its Power Manager system. The warning will
be sent by Company as soon as Company determines that events warrant a change from a
normal status to a warning status.
c) Interruption. The system is experiencing an interruption in this state. An interruption can
occur without the issuance of a warning.
(3) For interruptions invoked under conditions 2, 3 and 4, the shortest amount of time between Ihe time
when Cusmmer is notified that it has m be in interruptible compliance and the time when it must be
in compliance to avoid a penalty will be Iwo hours. For interruptions invoked under condition 1
(reliability), Customer may be asked to interrupt immediately and will be expected to make its best
efforts to comply immediately if asked to interrupt immediately. Under condition i interruptions, nom
compliance penalties will not be assessed for Customer behavior within the lwo hour period from the
time when Customer is called to intermpt.
(4) Company shall not be liable for any loss, damage or injury to Customer or to any other person, Sirm
