Introduction

In this interview, we want your insights into how a power system recovers from a major hurricane. We are especially interested in understanding how disruptions in other infrastructure systems, such as water and transportation, impact its recovery. We are conducting similar interviews with PRASA and DTOP to learn the same for water and transportation systems.

We are specifically interested in the recovery of power systems from Hurricanes Irma and Maria, which made landfall in September 2017.

We are going to ask you about the time before and the time after Hurricanes Irma and Maria. We recognize that the two events occurred within two weeks of one another and that it may be difficult to remember back that far or to separate the effects of the two storms from one another.

Please answer to the best of your ability.

We use some terms in this survey to keep the questions consistent across interviews with all infrastructure types. We refer, for example, to “your organization.” We recognize that you may more naturally refer to your “department”, “office”, “agency,” “company,” or “utility.” But for uniformity in conducting interviews for all infrastructure types, we use the generic term “organization”.

Section A. Confirm screening

1. Can you confirm the organization on behalf of which you are providing answers:

• PREPA

• LUMA

• Other:__________________

2. Can you confirm the geographical area, or as we’ll refer to it in this interview, “service region”, for which you are providing answers:

• The entire area in which your organization operates within the island of Puerto Rico

• [List of LUMA/PREPA Regions]

• Adjuntas

• Aguas Buenas

• Aibonito

• Bayamón

• Caguas

• Carolina

• Catano

• Ciales

• Cidra

• Guaynabo

• Gurabo

• Humacao

• Jayuya

• Juncos

• Lares

• Las Piedras

• Maunabo

• Mayagüez

• Naguabo

• Ponce

• San Juan

• San Lorenzo

• Toa Baja

• Trujillo Alto

• Utaudo

• Yabucoa

• Other: _______________

Please assume we are only asking about your organization's operations within this specific service region, even when it is not explicitly mentioned.

In addition, we will refer to “your system.” By “your system”, we mean your organization’s physical assets, systems, and networks, such as power plants, transmission and distribution lines, substations, administrative buildings, etc., located within your service region.

Section B. Introductory questions

The first set of questions asks about your service region.

3. Are there any major critical buildings in your service region? The building type “critical buildings” includes but is not limited to hospitals, fire stations, police stations, emergency operations centers, and public buildings used as shelters, such as schools.
   [Open-ended]

4. Are there any major commercial buildings in your service region? The building type “commercial buildings” includes but is not limited to buildings in financial and business centers/districts, and manufacturing plants.
   [Open-ended]

5. How many residents or households are served?
   [Open-ended]

6. What are the power sources for your service region? For example, power generation facilities, substations, transmission lines?
   [Open-ended]

Next, we ask questions about your professional involvement in the power industry.

7. How many years in the power industry have you worked? (years) ____

8. How many years have you worked in your current organization (in any position)? (years)_____

---

We want to make sure you become familiar with Table A since we will use this table more than once. In what follows, we are going to ask you the extent to which your organization provided specific attributes of power service to different building types. You’ll be asked to select an extent ranging from “Completely” to “Not at all”. You’ll be asked to do this for “All buildings”, “Critical buildings”, “Commercial buildings”, and “Residential buildings”. Table A should be used to help you to answer the questions.

You will reference Table A more than once because we ask about different attributes of power service and we ask about different periods of time.

Section D. Dependencies on other systems—Effect of disruptions on service recovery

In this next set of questions, we ask you to identify disruptions that had an impact on your organization’s recovery of service, either by delaying specific steps of recovery, making recovery items proceed slower than they otherwise would (“throwing sand in the gears”), presenting obstacles that had to be overcome or gotten around, or in any other way frustrating efforts to recover service. We ask all infrastructure service providers about the extent of impact to service recovery of disruptions in goods and services in six categories: communications, transportation, water, energy, economy, and government. We take them up one category at a time.

[Interviewer: Show (or have them retrieve) Table C]

-----

Table C. To what extent did disruptions in the following impact service recovery?

	Not at all	Very little	Somewhat	To a great extent	Not applicable (NA)	Don’t know (DK)
Item 1
Item 2

In answering, please consider...

Impact on recovery of service to pre-Hurricane Maria levels

the entire period of service recovery, from just before landfall through repairs (temporary or permanent) necessary to recover service

only direct impacts on service recovery

-----

We’ll ask you to indicate the extent to which disruptions in each of a set of items impacted service recovery, with responses ranging from “Not at all” to “To a great extent.”

In answering, please consider the period from the leadup to landfall, landfall, damage assessment, through to completion of the repairs necessary to recover to pre-Hurricane levels all service attributes, including: supplying the demanded amount of electric power, providing power quality, and providing electric power at all times of the day.

Further, we ask that you consider only direct impacts. To illustrate what we mean by direct, consider the following example. Suppose that outages of traffic signals impacted your organization’s recovery of service. Even though you may know this resulted from a power outage, in this example, the transportation system directly impacts recovery of service (the power system only indirectly).

Communications

First, we will consider the impact of disruptions in Communications.

19. To what extent did disruptions in the following impact service recovery?

	Not at all	Very little	Somewhat	To a great extent	NA	DK

21. To what extent did disruptions in the following impact service recovery?

	Not at all	Very little	Somewhat	To a great extent	NA	DK
Sewer or stormwater, drainage, or flood control
Wastewater system
Water supply system

Energy

Next, we will consider the impact of disruptions in the Energy sector.

Your organization provides a service that matches one or more items within the Energy category. When we encounter such an item, consider disruptions in items only to include those not under your organization’s control. Items not under your organization’s control may include, for example, the parts of the power system that lie outside of your service region. If none exist, please indicate ‘Not Applicable’.

22. To what extent did disruptions in the following impact service recovery?

	Not at all	Very little	Somewhat	To a great extent	NA	DK
PREPA (now Luma) electric power
Availability of temporary power sources (generators, batteries, etc.)
Availability of fuel (diesel, gasoline, ...)
Maintenance/repair service for temporary power sources, e.g., generators

Economy

Next, we will consider the impact of disruptions of the broader Economy. This includes disruptions in goods and services that were not previously called out.

23. To what extent did disruptions in the following impact service recovery?

	Not at all	Very little	Somewhat	To a great extent	NA	DK
Labor hiring pool
Financial system
Suppliers to the power industry
Durable goods suppliers (heavy or light equipment not specific to the power industry)
General consumables (not fuel, not specific to the power industry)
