Reliability Performance and Power Quality Resolution Process DTE Electric Report for 2018

1

Background

On September 5, 2009, the Michigan Public Service Commission issued an Opinion and Order in Case No. U-16065, in which it directed that the two major Michigan utilities 1) provide information related to SAIFI,

CAIDI, and SAIDI reliability indices with and without major events , on a rolling five year average basis, using the industry standard IEEE method of calculation, and 2) file an annual power quality investigation

report which contains data on all primary customer power quality investigations conducted in the past year for end-use customers, derived from their power quality meters, and the outcome of each

investigation. This report contains the DTE Electric January 1, 2018 through December 31, 2018 results and compliance status per those requirements.

On December 4, 2014, the Michigan Public Service Commission issued an Order in Case No. U-17542, in which, in part, increased reporting requirements for Consumers Energy Company and DTE Electric

Company relative to ongoing dockets Case No. U-16065 and Case No. U-12270. The additional information is to be provided no later than April 2 of each year. The additional reporting requirements

are:

1. a list of their 10 worst performing circuits for the prior year in terms of both SAIDI and SAIFI; 2. for each of the 10 worst performing circuits, the utility shall provide the following information:

(a) SAIDI and SAIFI excluding major events for the year, (b) circuit name, number and location, (c) length of circuit (miles), (d) number of customers served, (e) substation name, (f) last circuit trim, (g) list of outages and causes, and (h) corrective action plan to improve performance;

3. number of customers experiencing multiple interruptions (CEMI) reporting for indices CEMI0 through CEMI10+; and

4. number of customers experiencing long interruption durations (CELID) reporting for indices CELID60hrs and CELID8hrs (excluding catastrophic events).

2018 Report Preface

In 2018, DTE Electric transitioned to using AMI meter data as the basis for outage data and reliability statistics. Prior to 2018, DTE Electric’s outage management system (InService) was the basis. To our knowledge, no other utility in the country is using AMI meter data to determine reliability statistics. The AMI-based reliability statistics provide the most accurate reflection of the customers’ reliability experience.

A comparison of the 2018 data versus the 2017 data shows an increase in interruption events, but a decrease in customers interrupted and minutes of interruption. While the decrease in customers and minutes interrupted can be attributable to better weather conditions and on-going reliability improvement programs, the increase in interruption events cannot. While further investigation is on-going, the data appear to indicate that an increase in one leg (120 volts to neutral) outage events corresponds to a similar decrease in non-outage low voltage events. One hypothesis is that when voltage on the one leg that powers the AMI meter drops below the power supply threshold, the meter records an outage event; whereas in the past, lacking AMI data, the event would have been categorized as a non-outage low voltage event. Per IEEE-Standard 1366, low voltage events are not considered interruptions.

IEEE Standard 1366 Definitions

Interruption The total loss of electric power on one or more normally energized conductors to one or more customers connected to the distribution portion of the system. This does not include any of the power quality issues such as: sags, swells, impulses, or harmonics. See also: outage

Outage The loss of ability of a component to deliver power.

From AMI meter data, it cannot be determined whether some meter interruptions were actual one-leg service interruptions or one-leg low voltage events; DTE Electric has chosen to include them in reliability reporting as if they were interruptions.

AMI meter data contains no interruption cause codes. To determine the cause, an effort is made to associate each interruption event with an InService event in which the cause of the interruption is recorded by the crew. However, not all AMI meter events align with InService events. The percentages of interruption events by cause in this report are based on those events where the associated cause is known.

AMI meter data is used to determine CEMI and CELID statistics.

In 2018, DTE Electric experienced 30 weather events: two were catastrophic storms interrupting greater

than 10% of its customer base (MPSC catastrophic criteria). In 2018, DTE Electric was in storm restoration mode for 92.1 days (9.8 days for the MPSC catastrophic storm and 82.3 days for smaller storms) – yet by IEEE definition, there were only nine MEDs. Hence, a significant portion of the storm restoration is

included in the non-MEDs metrics.

Major Event Days

A total of four Major Event Days occurred during DTE catastrophic storms. In addition, five Major Event Days occurred during DTE non-catastrophic storms and normal conditions.

Reliability Performance – Customers Experiencing Multiple Interruptions (CEMI)

Per IEEE Definition, CEMI n represents the number of customers experiencing n or more interruptions.

Hence, in the table below, each discrete CEMI level is a subset of the CEMI levels above it.

CEMI N # Customers

CEMI 0 2,191,374

CEMI 1 1,399,468

CEMI 2 765,711

CEMI 3 413,715

CEMI 4 208,042

CEMI 5 99,455

CEMI 6 45,757

CEMI 7 19,844

CEMI 8 9,647

CEMI 9 4,867

CEMI 10+ 2,623


11

Reliability Performance – Customers Experiencing Long Interruption Duration (CELID)

The CELID customer count is based on the Single Interruption Duration (rather than the Total Interruption Duration) defined in IEEE Standard 1366-2012, Section 3.2.8, Equation 15; i.e. it represents each occasion

a customer was interrupted based on the CELID duration, not the total time during the year that each customer was interrupted.

CELID - Single Interruption Duration # Customers

CELID 8 hours - MPSC Normal Conditions 220,502

CELID 16 hours - MPSC Normal Conditions 85,329

CELID 60 hours - MPSC Catastrophic Conditions 10,060

CELID 120 hours - MPSC Catastrophic Conditions 98

Per MPSC Case U-12270, catastrophic conditions are defined by either of the following:

(a) severe weather conditions that result in service interruptions for 10% or more of a utility’s

customers (b) events of sufficient magnitude that result in the issuance of an official state of emergency

declaration by the local, state, or federal government


12

Power Quality – Inquiry Process

DTE Electric (DTE) has a proven effective process in place that enables its large industrial and commercial customers typically served off the subtransmission or transmission system to obtain resolution of power

quality issues. The customers contact their assigned account representative who in turn starts the process of helping the customer by engaging the appropriate engineer in Distribution Operations. DTE and

ITCTransmission (ITCT) have a very successful process concerning the transmission system events.

The response to the customer normally includes the following steps: (1) Obtain pertinent information about what is troubling the customer (old or new equipment, one

device or many) (2) Gather the dates and times from the customer to correlate with EMS Alarm Logger events (cap

switching, line trips) (3) Correlate the customer's experiences with the power quality meters at the service point or with

power quality meters in the area

(4) Meet with the customer about the correlation of system and customer events.

Based on the correlation of DTE and customer events, the following outcomes or additional steps are possible:

(1) Special power quality monitoring (DTE or customer) could be installed to determine customer equipment sensitivity and source of problem

(2) Customer conducts site survey to determine if his operating voltage is optimal (3) Trouble with minor sags from DTE system (sensitive equipment) - customer's responsibility to

make compatible (4) Internal system trouble - customer's responsibility to make equipment compatible

(5) ITCT/DTE will seek resolution of problems caused on the ITCT/DTE systems where the customer equipment wouldn't be expected to have ride-through to significant voltage sags. The rate of

occurrence, system exposure, and service method determine if remedies are commercially feasible


13

Power Quality – Monitoring

DTE has an array of power quality meters across its system at key industrial, subtransmission, and distribution buses that have proven to be very effective. New meters are installed at new or upgraded

industrial substations and on subtransmission buses.

The power quality meters at the industrial locations allow DTE to correlate the recorded voltage sags with system events from the SCADA-EMS system. This system provides DTE with information unique to the

customer and a tool to track the performance of the system. The system performance data is used to prioritize capital improvements and system maintenance.

The power quality meters on the subtransmission and distribution buses provide system performance data plus the ability to calculate the probable locations of faults on the lines. This information will reduce

the time and cost to find causes of voltage sags and facilitate system repairs when necessary.

Also, voltage sags on the DTE system can be correlated with faults on the ITCT system. The DTE power quality data is shared with ITCT for the benefit of resolving customer power quality issues.

1 Voltages and durations (IEEE Std 1159 Table 2 – Categories & Typical Characteristics of Power System Phenomena) 2 Number of customer locations impacted 3 Equipment owned by DTE (120, 40, 24, 13.2 and 4.8 kV) 4 Equipment owned by ITCT (345, 230 and 120 kV) 5 Equipment owned by the customer or other power systems not owned by DTE or ITCT 6 Inquiry numbers – event detail provided in the table below

The number of locations impacted and identified by power quality monitors, system monitors and customer inquiries was 83 during 2018, which was less than the 147 total for 2017. The 2018 data is based on 29 fewer PQ monitor locations than in the past. These locations had obsolete monitors


15

and sub-standard communications that were removed in 2018. Installation of the replacement monitors will begin in 2019. The follow-up investigations indicate that most of the power quality events were due to either voltage sags (94%) or interruptions (6%) and correlated with trouble occurring on the DTE (93%) and ITCT (6%) systems. Other inquiries were determined to be a result of events occurring on customer systems (1%). Of the events on the DTE and ITCT system, 33% were attributed to adverse weather, contamination, or tree interference. System improvement projects underway would have reduced the locations impacted by 28% of the total. Along with line clearance, modifications such as operating practice changes, equipment changes, adding animal protection and/or equipment are typical actions taken to reduce the occurrences of the events. The following table lists information about each inquiry.
