NYSEG PSC Scorecard: May 15, 2018 Thunderstorm                                                                                                                     ii
STORM SUMMARY
NYSEG (the Company) prepared for and responded to a thunderstorm event beginning May 15, 2018 with
restoration activities continuing through May 21, 2018. This weather event caused winds in excess of 65 mph in
the Brewster and Liberty divisions. As two divisions had restorations lasting longer than 72 hours, the Company is
providing an Emergency Response Scorecard for this event. The Company complied with their Electric Utility
Emergency Plan throughout this event.

Weather Forecast:
The Company used two weather forecasting services, DTN and ATMOS. The Company also reviews National
Weather Service (NWS) and other governmental or readily available weather sources, or media-based weather
sources. DTN issued a forecast on May 13 at 6 AM with an advisory for a thunderstorm event on May 15. ATMOS
issued a forecast on Monday that indicated the state would receive non-severe thunderstorms, with heavy
downpours and low frequency cloud to ground lightning; damaging wind gusts were not expected. There was a
possibility that the southern third of the state would not see the storm impacts. Meteorologists were predicting a
high wind associated with the band of thunderstorms predominately on the eastern side of the state. On May 14
with the 3 PM report the winds gust forecasts were increased to 55 mph with a potential of 60 mph. The forecasts
wind gusts again increased in the May 15 2 PM forecast to 65 mph gusts with a 70% confidence level. This storm
intensified with nearly no warning; the Company receiving warnings from their contract meteorologist, ATMOS,
and National Weather Service at 2:44 PM that the weather system was increasing, developing the threats of
tornadoes across southeastern New York.

Actual Weather:
The high winds and thunderstorms forecasts materialized in the afternoon, at approximately 3 PM, through the
evening of May 15. Associated with the thunderstorms were confirmed tornados in Ulster, Sullivan and Orange
counties in the Liberty division and in Putnam County in the Brewster division. Wind gusts were recorded in excess
of 65 mph in much of these areas and a peak gust of 78 mph was recorded in Dutchess County. Hail from 0.75”-
2.75” was recorded as part of the thunderstorm and tornado activity.

The following divisions reached the 72 hour threshold for Scorecard reporting:

                 Peak        Peak Day/Time       Start of Restoration   90% Customers      Fully restored   Total affected

May 14, 2018

On Monday, May 14, 2018, the Assistant Area Commander – Planning provided the Area Commander and Area
Command - Deputy the weekly availability report. This report provides the full time equivalent (FTE) resources
available by location for Company line, contract line, contract tree and UC&M, with details listed by location for
line and tree workers. This report is found in Appendix C.

The Company’s contract meteorologist DTN issued a forecast alert for a potential EEI Threat Level 2 gusts and EEI
Threat Level 2 sustained winds event for day two. EEI levels are defined as follows:

After the release of this DTN forecast, the following email was sent to all Area Command and Incident Command
Staff on May 14 at 7:26 AM.

May 15, 2018

At 6 AM, the Company’s contract meteorologist DTN issued a forecast alert for a potential EEI Threat Level 3 gusts
in the Liberty and Brewster Divisions and EEI Threat Level 2 sustained winds event for day one. EEI levels are
defined above. At 2:11 PM, the Company’s contract meteorologist DTN issued a forecast alert for a potential EEI
Threat Level 4 for lighting, Level 3 gusts in the Liberty and Brewster Divisions and EEI Threat Level 2 sustained
winds event for day one. At this time, Liberty, Mechanicville, Oneonta and Brewster Divisions were all put under a
possible tornado watch.

According to NYSEG’s Emergency Operating Procedure EOP-040 (Appendix B), Resource Staging and Allocation
Process, the Company’s Damage Prediction Model is run when NYSEG receives a weather forecast alert above an
Energy Event Index (EEI) 2. The EOP-040 outlines the following steps:

       Monitoring of forecasts and prediction modeling
       Resource availability and needs based on event predictions
       Resource acquisition from affiliates, contractors and mutual assistance groups
       Resource staging

Company personnel continued to follow the steps covered in EOP-040 Resource Staging and Allocation Process.

As a result, at approximately 3 PM, the Area Commander placed all Area Command and Incident Command staff
on alert for a May 15, event per the Company’s Electric Utility Emergency Plan. Incident Commanders were
contacted and all areas were requested to hold all staff beyond normal closing and prepare for mobilization of wire
guards and damage assessors.

The first request for crew movements began immediately after the DTN threat level 4 was issued. Fifteen
contractor crews were requested to begin movement from their staging area in Binghamton to the Brewster
Division at 4 PM. Crew movement requests continued throughout the day and evening and by 9:30 PM, 490
contractor FTEs were in route to Brewster and 81 contractor FTEs were in route to Liberty as well as 38 internal
FTEs.

A NAMAG (North Atlantic Mutual Assistance Group) call had been scheduled for 2 PM. The Company was holding
their native and non-IOU (Investor Owned Utility) resources acquired for the pending weather due to being subject
to the event, as the call was occurring before the extreme weather was known. During the call, all NAMAG
members were made aware of the developing weather (as was known at that time), and a second call was
scheduled for 7:30 PM. The one offer available (60 FTEs from Canada) was not taken by any member companies as
the group determined that the weather impacts were not fully known at this time, and that it would be a better
use of the resources to await actual impacts before making the allocation. Further details on resource requests
after event impact are detailed in Section 11 – Mutual Assistance.

Pre Storm Communications

Consistent with our Company’s Electric Utility Emergency Plan Section 9.2, the Public Information Office, in
conjunction with Area Command, enacted pre-event communications to help raise awareness.

NYSEG took measures to communicate pre-storm messages to the general public. Pre-storm communications
included messages on Twitter, and Facebook posts.

Communications included the following:
    How customers should prepare in advance of the event
    Methods to contact the Company
    Where to find outage information
    Safety reminders for wires down and power restoration
    Crews will be working until service is restored to every customer

Methods of communication included the following:
    Three Twitter messages: Starting at 4:02 PM on March 15
    Three Facebook posts: Starting at 4:02 PM on March 15

Pre-storm email communications were not sent prior to the event as the potential extent of the extreme weather
was not known until a few hours before the start of the event.

1.6 COMPLIANCE WITH TRAINING PROGRAM
 1.6   Company compliance with Training Program as specified in Commission Approved Emergency Plan

Consistent with the Company’s Electric Utility Emergency Plan Section 6.4, all activated individuals in the Customer
Relations Center, Damage Assessors, Public Liaison Officers and Wire Guards had received the necessary role-
specific training.

Personnel in functions required to support field operations during outage events receive training for their assigned
roles. Each emergency response role is assigned a subject matter expert (SME) who is responsible to develop and
maintain course materials and ensure employees assigned an emergency role receive the necessary training.
Training is delivered in a variety of methods, according to the requirements of the role. Course materials, job aids,
checklists and other role-specific information are stored on the Company’s StormCenter Intranet site, which is
accessible by all employees. Employees’ training includes company-designed exercises, which include drills,
tabletop and full-scale exercises.

In some cases employees are trained to perform their emergency response role as part of their regular job
functions. One example is our customer representative position, where employees are trained to respond to
outage calls as part of their regular job progression training.

On site and refresher training is provided as required. During times of need for additional support, “just-in-time”
training can be provided to employees.

1.7 PARTICIPATION IN ALL PRE-EVENT MUTUAL ASSISTANCE GROUP CALLS
 1.7   Participation in all pre-event mutual assistance group calls

The Company’s Electric Utility Emergency Plan Section 7 outlines our interactions with mutual assistance
organizations.

NYSEG participated in mutual assistance activities as a member of two mutual assistance organizations:
    North Atlantic Mutual Assistance Group (NAMAG), a consortium of investor-owned utilities (IOUs) in the
       Mid-Atlantic, New England and Canadian Provinces of New Brunswick, Ontario and Quebec.
    New York Public Private Mutual Assistance Protocol (NYPPMAP), an assistance agreement among New
       York IOUs, the New York Power Authority (NYPA), members of the New York Association of Public Power
       (NYAPP), and members of the Municipal Electric Utilities Association of New York (MEUA).

Notes from the NAMAG leadership calls can be found in Appendix F. No notes were provided for interactions
among the membership of NYPPMAP.

May 15, 2018
Due to the short lead time between the weather forecast warnings and event impact, only one NAMAG call was
held prior to the event impact, at 2 PM on May 15. The Company participated in this (and all) mutual assistance
meetings and held resources due to being subject to the potential weather event. Subsequent to the event impact,
the Company requested transmission and distribution line resources and tree resources from all mutual assistance
partners. All the Company’s New York requests for this event were for the NYSEG service areas as the RG&E
service area did not receive sustained damage.

NYSEG reached out to the NYPPMAP on May 15 at approximately 5 PM to make them aware that an event was on-
going and requested available municipal and NYPA resources.

NYSEG complied with their Electric Utility Emergency Plan Section 7 in regards to mutual aid organization.

       within 24 hours

Standard stock levels typically include materials for planned work, unplanned work and storm coverage. Materials
were found to be at more than adequate levels based on forecasts of system impacts. Following Stores Storm
Operating Process (Appendix B) all staffing was advised of the potential storms. Inventory Management alerted
key vendors to be on standby due to a potential event. Additionally, storm kits with general stock for contractors
to utilize during the restoration event were available.

NYSEG’s activities and the data demonstrate compliance with our Electric Utility Emergency Plan Section 6.3 and
the appropriate verification of storm stocking levels as set forth in the measurement criteria for this metric.

      Assessment

Per the Company’s Emergency Operating Procedure EOP-022 – Preliminary and Detailed Assessment Information
Gathering which can be found in Appendix B, the objective of preliminary assessment is to capture the most critical
information like broken poles, blocked roads, trees or tree debris on company facilities and leaking or damaged
transformers. Preliminary damage assessment is critical in establishing restoration resource needs and
development of preliminary ETRs. This assessment is conducted by vehicle at speeds safe for road conditions and
does not include off road right of way assessment. All damage assessment teams or individuals were provided an
iPad with accessories (car charger, stylus, instruction manual, and laminated assessment instructions) and a
printed circuit map of the area to be assessed.

The NYSEG Brewster and Liberty divisions completed preliminary damage assessment within 24 hours from their
respective start of restoration. In addition to damage assessors, all areas utilized additional means to gather
damage data, such as customer calls, municipally reported damage, local official calls, Outage Management
System (OMS), Field Circuit Coordinators (FCCs) and field crews. The Company also uses data provided by
municipal partners that participate with a damage assessment application. All damage data is instrumental in
establishing ETRs and necessary when creating crew packets for restoration crews.

                             committed to the utility

The Company determines weekly crew availability each Monday as identified in Section 1.1, and then initiate the
Contract Coordinator and MAG liaison roles as part of the Area Command and Area Command – Planning
functions. On Monday May 14, a normal level of line and tree FTE complement was available; this was increased
significantly to reflect the additional resources required to enhance restoration efforts.

NYSEG followed procedures outlined in EOP-040, to determine staffing, along with crewing guidelines outlined in
Section 8.1.1 in the Company’s Electric Utility Emergency Plan, Activation. Damage Prediction models run on May
14 indicated the potential for minimal incidents affecting less than 600 customers and less than 10 incidents. By

ETR calculations, as documented in Section 8.2.1 of the Company’s Electric Emergency Plan, are based on a
number of data points that are refined over time. These data points include the number of incidents, the types of
incidents and the available crew resources. As the data becomes more robust (completed assessments, resources
on site), the accuracy of the ETR will increase.

The Company’s Electric Utility Emergency Plan Section 9.7 outlines our interactions with Public and Emergency
Management Officials.

NYSEG coordinated with municipalities on a continuous and as needed basis throughout the event. Public Liaison
Officers were assigned to county and local jurisdictions as well as the Sullivan County, Orange County, Putnam
County, and Westchester County Emergency Operations Centers (EOC) which served as a central point of
coordination for the county.

Municipal contacts and requests were logged for tracking and follow up with the Incident Commander or
appropriate ICS functions. The Company uses ICS-214 forms to log contacts and notable activities. A consolidated
PLO “issue log” is used to track requests received through EOCs and municipalities. An issues log was used in the
NYSEG Brewster and Liberty divisions. The log was updated by Company staff and prioritized with the Incident
Commander. Many requests for information were responded to immediately or crews were dispatched for critical
needs. There was continuous communication with municipalities to close loops when an issue was resolved or
information obtained.

NYSEG Brewster Division:
In addition to the daily municipal calls reported in Section 14 and providing daily news releases, PLOs were
available 24/7 to local municipalities and counties.

More than 330 personal contacts were made with town, city, village and county representatives during the event.
Methods of contact included emails, telephone calls, fax, and/or text messages depending on the elected or
municipal official’s preferred method of contact, the information being conveyed and the complexity of the issue
under discussion. Interactions (proactive and responsive) with municipal and elected officials focused on the
following areas of interest:
      ETR updates
      General situational awareness (check-in calls, planned outages, work plans)
      Critical facilities, facilities of interest to municipalities and key account customers
      Outage notifications/updates
      Road clearing/road closures
      Wires down, poles down, trees with wires
      Crewing information
      Specific outage inquiries
      Dry ice/bottled water availability
      Lodging availability

The Company’s Electric Utility Emergency Plan Section 9.7 outlines our interaction with Emergency Management
Officials.

Contacts were made with Sullivan, Orange, Putnam, Dutchess, and Westchester Counties at the onset of the event
and as necessary throughout the event. In accordance with communications protocols established with the
counties for emergency events, NYSEG made contact with municipal and emergency management officials.
Interactions at the county level centered on general situational awareness and briefings, outage updates, road
clearing, lodging, critical facilities and ETRs.

A Liaison County/Local (EOC Representative) was assigned to the following counties Emergency Operations
Centers: Sullivan, Orange, Putnam, and Westchester Emergency Operations Centers.

EOC representatives also participated in daily municipal officials’ conference calls.

Even though Ulster and Delaware County did not open their EOC, a Public Liaison Officer (PLO) was in regular
contact with county emergency management personnel throughout the event. Additionally, county EOC personnel
provided information to the Company’s PLO regarding, wires down and road closure issues, and customer/facility
specific concerns.

Major interactions included:
    Road clearing: In an effort to expedite opening roads closed due to downed wires and trees, NYSEG
         provided dedicated crews to work with the counties. The counties evaluated and prioritized closed roads
         and then coordinated with the crews so conditions could be made safe for county and municipal crews to
         clear downed trees and reopen the roads.
    Critical facilities: Reports were provided to the EOC twice per day of the remaining critical facilities
         without power and ETRs. Key facilities included senior living centers, nursing homes, command
         center/communications center, water facilities and pump stations.
    Lodging: Coordination of available lodging for crews in the Brewster and Liberty area were made between

                             gas, communications, water)

Per Section 7.1 of the Company’s Emergency Plan, coordination with gas, telecom, and other utilities occurs in
preparation for, or during, significant events. NYSEG coordinated with other utilities to address needs in the
impacted areas. Supervisors on job sites, and line personnel were available to work on site with utility partners. In
accordance with the Company’s EOP-035, Municipal Coordination (Appendix B), NYSEG also had Public Liaison
Officers/County/Local Liaison Officers activated and available to interface with other utilities; these utilities are
briefed annually regarding contact procedures during an event. These liaisons were on site at the open County
EOCs and in contact with those EOCs which were not open but had staff engaged in event response.

Examples of coordination include:
    In the NYSEG Brewster division, the Pole Setting Branch Director was in direct contact with Verizon
       Communications as they provided an onsite liaison in order to effectively coordinate and prioritize pole
       setting operations. NYSEG Operations Section Chief was also in communications with a Supervisor at
       Metro North, the local Supervisor from Comcast as well as the local Supervisor from Cablevision to
       provide information on poles set as well as offering assistance with any needs they may have had.

         In the NYSEG Liberty division, the Company worked with neighboring electric utilities to coordinate
          restoration efforts for interconnected customers.

NYSEG also coordinated through Dig Safely NY to ensure that NYSEG facilities were marked to provide safe digging
environments for other utilities (i.e. telephone, water, cable). Company representatives worked with respective
EOCs to coordinate restoration of key water utility facilities such as treatment plants and pumping stations and a
communication center.

NYSEG effectively coordinated with other utilities and complied with the Company’s Electric Utility Emergency Plan
Section 7.1 in regards to utility coordination.

The Company’s Electric Utility Emergency Plan Section 5.4 outlines our interactions with mutual assistance
organizations. Refer to Section 1.7 for pre-event mutual assistance activities and see below for mutual assistance
activities during the event.

May 15
At approximately 5 PM, the Company requested that the New York Public/Private Mutual Assistance Protocol
(NYPPMAP) agreement among the utilities, the New York Power Authority (NYPA) and the municipal electric
companies be enacted. The Company requested any available transmission and distribution resources be made
available for event response.

NAMAG call 2 was held at 7:30 PM where Avangrid NYSEG/RG&E requested 100 line FTEs and 25 vegetation FTEs.
The Company received 62 line FTEs and 25 vegetation FTEs. Resource allocations were split amongst the impacted
companies, which included those outside New York, though no requesting companies’ needs were fully met with
the available resources. Allocated resources were already prepared to travel to the affected areas for work the
next day. As a result of the unmet requests, an additional call was scheduled for May 16, and the neighboring
mutual assistance areas (Great Lakes and Southeast) were notified.

For the remainder of the evening hours, the Company’s MAG Liaison continued contact with mutual assistance
partners at NAMAG and NYPPMAP to obtain and mobilize resources, including transmission workers from NYPA
who were directed to report to the Company’s Liberty division, where known transmission issues were already
assessed as causing the majority of known service interruptions. Internally, non-IOU resources were acquired from
Pennsylvania and staged in the Binghamton division for potential event response. These resources were to arrive
the evening of May 15.

May 16
NAMAG call 3 was held at 9:00 AM the Company maintained their open request for 100 line FTEs and received 12
additional line FTEs from Emera Maine.

locations: Arcadia, Fairport, Freeport, Oneida/Madison, Spencerport, and Steuben and 14 transmission line FTEs
from NYPA.

Municipal conference calls are required if events are expected to last greater than 48 hours, unless an alternative
contact method is more appropriate. The first municipal call must be scheduled within the first 18 hours of the
restoration period, with the first call held within the first 36 hours.

NYSEG held Municipal calls in the NYSEG Brewster and Liberty divisions. In these areas PLOs were assigned to
counties and individually addressed any concerns brought forth by the counties or the municipalities in those
counties.

Municipal calls were effectively managed by the lead Public Liaison Officer (PLO). All key items were covered.
Adequate time was allotted for questions from call participants and responses from the PLO or Incident
Commander as necessary. The calls continued until all questions were addressed. Direct contact information for
the PLO was provided on every call. Questions that were raised on the Municipal calls were either responded to
during the call and noted in the call minutes or were addressed by the PLO team following the call. The Municipal
calls were timely, provided daily information, and provided a forum for elected and municipal officials to discuss
other issues of mutual concern. With multiple representatives from many jurisdictions participating on the calls,
the Company allowed open and candid discussion while respecting the need to discuss key items and situations of
interest to the broader group. Department of Public Service (DPS) Staff attended the municipal officials’
conference calls and were alerted to the calls following the protocol established by DPS Staff.
