CROOKS, UTILITIES MANAG SUBJECT: OUTAGE NOTIFICATION OVERVIEW DATE: MARCH 7, 2014 Following a conversation during the March 3 Commission meeting, I have prepared an extensive overview of prior discussions with the City of Shakopee and the Utilities Commission in regards to electrical outage notifications. A timeline has been provided describing events that have sparked conversations with outage notifications since September 2012. Also attached are the most current Reliability and Outage Report, webpage analytics, twitter postings by Mayor Tabke requesting public input and information concerning our afterhours emergency contact provider, CCS. Timeline 9/21/12 — High wind event caused Circuit Breaker 7 to open at the Shakopee Substation that causes 570 customers to be without service. 10/9/12 —Joint meeting between Commission and City Council held at Shakopee Public Utilities. Mayor Tabke added agenda item to discuss outage notification. 10/10/12 — Mayor Tabke tweeted "do you want #Shakopee Public Utilities on FB /Twitter for outage information? Let them know ". Sidechirp was added by SPUC to monitor public response to inquiry. 12/25/12 — Christmas Day outage at 17th Ave and Brittany Drive affects 2000 customers. Failure of SPUC equipment causes the outage. 1/7113 — President Helkamp and the Utilities Manager met with Mayor Tabke and City Administrator Mark McNeill at City Hall to discuss the outage and customer notification possibilities. The meeting was requested by Mayor Tabke. 1/7/13 — A discussion of the meeting and follow up regarding the Christmas Day outage was presented during the regular scheduled Commission meeting. 1/22/13 — An overview of the outage and how it was handled by our afterhours emergency contact representatives, CCS, was presented to the Commission during the mid month meeting. 2/20/14— During the Winter Storm event, an electrical outage affects 2500 customers that was caused by the failure of Xcel equipment at the Shakopee Substation. The Utilities Manager was informed of the event, while on vacation in Nevada. 2/27/14 —The Utilities Manager received an email from Mayor Tabke concerning the lack of communication to our customers regarding the outage. 3/3/14— During the regularly scheduled Commission meeting, Electric Superintendent Athmann provided an overview of the 2/20 outage. Liaison Whiting brought up that he received a busy signal when calling the Utilities during the outage. The Commission requested an overview of outage notification issues that have occurred in the past. 3/5/14 —The Utilities Manager contacted CCS to discuss the "busy signal" issue. CCS staff stated that during the Winter Storm event they received 1000's of calls. SPUC is not the only customer of CCS and due to the severity of the storm event their operators were inundated with call volumes that overwhelmed their capabilities. 2012 RELIABILITYAND OUTAGE REPORT Super America, 1ST Ave West 1/27/2012 S A]KOPEE PUBLIC UTILITIES COMMISSION 2012 ELECTRIC OUTAGE AND RELIABILITY REPORT. The 2012 Shakopee Public Utilities Electric Outage and Reliability Report is the 12th annual report. Data on Outages of Shakopee Public Utilities (SPU) Electrical System were acquired throughout the year. The responding SPU line crew at the end of the electrical outage completes the outage report. The report information includes the cause of the electrical outage, substation circuit number, number of customers, date, estimated time the outage occurred and the time when the electricity was restored. At the end of the year, the outage data was compiled and is described in the first part of this report. As a procedure, we analyze these statistics to determine areas of concentration for electrical system improvement. Shakopee Public Utilities Reliability Indices are also derived from this data and are reported in the later part of the report. We are required by Minnesota State Statute 21613.029 to provide this report, annually, to the Utility's Governing body. How Shakopee Public Utilities Electric Department designs and operates its electrical distribution system, plans maintenance, performs construction and responds to outages have a big impact on the utilities electrical system reliability performance. The Reliability Indices provide a method to assess the performance and dependability of SPU's electric distribution system. They also can be utilized to compare statistics with previous SPU and other Electric Companies Reliability Statistics. SPU has recorded outages for a 19 year period. The historical lowest number of outages, 71 outages, and resulting low reliability indices occurred in 2011. The 2012 Reliability Report shows an increase in number of outages and a significant increase in the four report indices. Notably, two incidents (Pike Lake Sub outage and 6th Ave Accident) contributed approximately 25% of the increases in indices numbers. The Shakopee Electric Department provides customer service, constructs and maintains SPU's electric distribution system and the City of Shakopee street light system. SPU electric distribution system consists of approximately 30% of overhead and 70 % underground facilities. The system has 5 substations with 30 distribution circuits. There are 236 miles of underground lines and 104 miles of overhead lines. The system includes 4,051 power poles, 792 overhead transformers and 2,018 pad mount transformers for the underground areas.

Common reasons for the losses are impedance and reactance in conductors, transformer excitation current, magnetizing inductance, power theft and inaccurate metering. Keeping track of losses reflects the efficiencies of the design and operation of the system. Shakopee Utilities did not account for 11,076,439 kWh of power during 2012. This is a loss of 2.7% is down from 3% in 2011 of the power purchased and is the lowest percent of line loss in the last 10 years. 7.0 6.0 5.0 Percenat0 oa 3.0% 2.0 1.0 0.0 Percent of Line Lass 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 Year Page 4 OUTAGE RESPONSE During 2012 SPU electric crews responded to 120 reports of power outages. The outages listed in this report are Sustained Outages, which are defined as outages of more than 5 minutes. The total number of customers served on the last day of the reporting period is the basis of this report. Subtracting the number of outages which did not involve SPU facilities (i.e. customer fuses and faulted customer underground service wires), the total number of outages involving SPU facilities is 89 for 2012. 160 140 120 L0 0 �0 O Li 0 W W go 20 0 OUTAGES ON SPU ELECTRIC SYSTEM ?002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 YEAR Page 5 148 ,50 .:. 140 143 105 89 _ lam. ?002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 YEAR Page 5 OUTAGE CAUSES Again the leading cause of power outages on SPU electrical system was due to animals. SPU had 24 outages caused by squirrels, one by a bird and one by a raccoon on its electric distributions system. Power outages caused by animals are the leading cause of all outages for power utilities in the United States.

The most commonly used reliability indices are SAM, SAIDI, CAM and ASAI. The definitions of these indices are described below and are consistent with IEEE Std. 1366- 2003 "IEEE Guide for Electric Power Distribution Reliability Indices ". SAM — System Average Interruption Frequency Index The average number ofsustained outages that a customer would experience in a year. SAM = Total plumber of Customer Interruptions (> 5 minutes) Total Dumber of Customers Served SPIT 2012 SAAIN 0.56 SAM — System Average Interruption Duration Index The average amount of time a customer on the utility's system spent without power during the year. SAIDI = Number of Customer - Minutes Interrupted (> 5 minutes) Total Dumber of Customers Served SPU 2012 SAIDI 40.11 minutes CAM — Customer Average Interruption Duration Index The average amount of time a customer can expect to be without power when they lose power. CAIDI = Number of Customer - Minutes Interrupted (> 5 minutes) Dumber of Customers Interrupted ( >5 minutes) SPIT 2012 CAM 71.27 minutes ASAI — Average Service Availability Index Represents the fraction of time that a customer has received power during in the year 2012.

CCS's staffing of call attendants during normal working hours is 20 — 30 people. They ramp up to 40 attendants during busy call hours (late afternoon — early evening) and their staffing is 10 -15 attendants during the rest of the night to morning.. This staff answers our calls as well as their other clients. On December 25, 2012, during our electrical outage, Steve thought they had 15 attendants staffing the phones. If all attendants are busy, the phone calls are answered automatically with a message that says "all attendants are busy please stay on the line ....." and then are put into a phone queue. This phone queLle wil! he!d six calls. If all attendants are busy and the phone queue if full, the call will not be answered and will revert back to SP U's phone system for handling according to our phone system protocol. CCS's average call length is 3 minutes. When answering an afterhour's call for SPU, they follow SPU's developed protocol, and if needed, notify our on call personnel. They will keep giving the calls to our on call person until they are informed by the on call person not to do so. When asked by the on call person, CCS attendants will also pass along information to callers about the status of the outage such as "a crew has been dispatched for repair" or "crews are working on the problem ".

To my surprise Xcel actually has a map that shows the location of the outage. They must not have any fears about security. http:llwv,rw.xcelenergy.com/0utages/Report a Problem /Outage Map /Outage Map At the time I did this they had 8 outages in the area: M01 MVEC has a link to a live outage map just above their Twitter button near the bottom of this page: littp://www.mvec.iiet/categor\//outage-update/ They'll only post something if the outage affects more than 500 customers. Rochester uses Twitter: http://www.rpu.org/tontact-us/power-outages.html MNPower services a large area of central and NE Minnesota. They have an "Outage Center" on the website. in addition to an outage map, they also offer an outage app for smartphones: http : / /www.mnpower.com /OutageCenter Food for thought. Regards, Mark Yost
