Public Utility District m
MEETING DATE: October 4, 2023
TO: Board of Directors
FROM: Steven Keates, Special Projects Administrator
Michael Salmon, Chief Financial Officer
SUBJECT: Residential Electrification Survey Results
APPROVED BY:
Brian C. Wright, General Manager
RECOMMENDATION:
Receive this presentation and provide feedback and direction to staff.
BACKGROUND:
The District's conservation programs are currently quite mature and have successfully
increased the saturation of many energy efficiency (EE) technologies. Due to this
success, `traditional' technologies, like LED lighting, have now achieved high levels of
saturation and are no longer viable means to generate real-world and cost-effective
impacts. This also comes at a time when both the Utility Commission and California Air
Resource Board are prioritizing electrification of California's homes, businesses, and
highways.
District staff are addressing these trends by re-designing its portfolio of conservation
programs to target viable energy efficiency technology, sustainable electrification, and
customer education. However, little is known about Truckee's current building stock, its
potential for electrification, or specific saturation of EE equipment within it. Such data
are imperative to design conservation programs which will successfully address
Truckee's unique needs.
Staff contracted with ADM Associated, Inc. to assist TDPUD determine the applicability
of electrification and various conservation mitigations within its service territory. ADM
Associates executed a saturation survey across District residential customers to collect
information on home characteristics and equipment, as well as use of and interest in
electric vehicles, space heating, water heating, and cooking equipment.
ANALYSIS AND BODY:
This presentation will provide an overview of the residential saturation study's
objectives, its approach, and a summary of its key findings for the District. Staff will
discuss how these findings will impact District customer program designs moving
forward.

TDPUD Electrification Survey Report
2 Executive Summary
2.1 Introduction
ADM Associates, Inc. was contracted to perform a survey of residential customers to obtain information
on home characteristics and equipment, as well as use of and interest in electric vehicles, space heating,
water heating, and cooking equipment.
2.2 Survey Methodology
ADM contacted TDPUD customers to complete the survey in late June and early July 2023. A census of
customers with sufficient data (i.e., email and address fields were complete) was selected for
recruitment. For customers with multiple properties, a single property was selected at random to ask
the customer about. Customers received up to two emails, an initial email and a reminder email.
In total, 917 customers responded to the survey, a number which represented a 9.4% response rate.
Response rates were somewhat higher for customers in the primary rate schedule strata than those in
the secondary rate class schedules.
Survey data were analyzed using weights based on the stratified design. Responses to several open-
ended questions were content coded and the codes were subsequently tabulated.
2.3 Key Findings
The following summarizes the key findings of the survey. Differences between primary and secondary
rate schedule customers are noted when survey results indicate that a difference was present.
Home Characteristics
• Most homes have insulated attics (74.2%).
Air leaks were not very common but primary rate schedule homeowners more often reported leaky
doors and windows:
o Windows: 19.3% reported air leaks (primary:25.2%, secondary:15.2%)
o Doors: 33.1% reported air leaks (primary:44.6%, secondary: 25.4%)
o Walls: 6.3% reported air leaks
Rebate Offerings
Agreement with the statement "I am aware of TDPUD's rebate offerings" was low with an average
rating of 2.6 on a 5-point scale. Secondary rate schedule customers agreed less with the statement
(2.5 vs 2.8).
Onsite Storage and Generation
• Solar panels (3.8%) and battery storage (4.1%) are uncommon. No respondents reported wind
generation.
Half of TDPUD customers thought they would install solar in the next five-years (50%), but a larger
share 80.7%said they would install battery backup.The greater interest in battery backup may be
admenergy.com 13239 Ramos Circle Sacramento, CA 958271 916.363.8383 1
Page 15 of 159
TDPUD Electrification Survey Report
due to concerns about maintaining power service, as loss of service was mentioned as a top concern
about electric space and water heating.
Electric Vehicles
17.7%of respondents reported owning one or more BEV. BEVs were more common than PHEVs
(5.9% reported ownership of one).
At home Level-2 chargers were present at 54.9%of electric vehicles residences. Multiple Level-2
chargers were uncommon among owners of multiple electric vehicles (8.5%of these customers
have more than one Level 2 charger).Another 28.7% reported using a Level 1 charger and 14.8%
said they don't charge at home.
Driving range, availability of charging stations, and availability of financial incentives for EVs were
rated as most significant in decisions to purchase an electric vehicle.
• There was not strong agreement that Truckee has adequate public access EV charging (average 2.9
on a five-point scale). Secondary rate schedule customers were less likely to agree that Truckee had
adequate public access charging than primary rate schedule customers (2.8 vs. 3.1).There was
somewhat higher agreement that respondents would like to see more charging stations (average
3.5). Secondary rate schedule customers were slightly more likely to agree that they would like to
see more public access charging than primary rate schedule customers (3.6 vs. 3.3)
Home Heating
• Most respondents (71.0%) primarily heat their homes using a central forced-air system.
• Natural gas is the fuel used by most respondents (80.0%)for their primary heating system.
• Respondents most commonly have a main heating system that is 14 to 30 years old (41.6%).
• The majority of respondents (54.5%) use a Wi-Fi enabled smart thermostat for their main heating
system, and these are more common among secondary rate schedule customers (62.5%)than
primary rate schedule customers (41.5%).
• The most common supplemental or secondary heating source for respondents' homes is a fireplace
or wood stove (57.7%). Less than 1%of customers that use a fireplace for supplemental heating
have an electric fireplace.
• When asked to agree or disagree with multiple statements about electric heating,the highest
average agreement rating was for "Electric heat for my home is safe" (average = 3.6) and the lowest
was for"I am interested in converting to electric heat for my home" (average= 1.4).
• For respondents who disagreed that electric heating was safe,the most common reasons for stating
that were concerns about service disruptions (mentioned by 49) and safety concerns such as fire
(mentioned by 19).
• By far,the biggest concern for customers who disagreed that electric heating was reliable was
disruption of service (mentioned by 287). The next most common issues were concerns about the
ability of their electrical systems or their grid to handle the load (mentioned by 8).
Home Cooling
The majority of respondents (65.1%) do not cool their homes. Central ACs were the most common
type of cooling system (8.6%of customers have one).

TDPUD Electrification Survey Report
Water Heating
• Standard tank water heaters are most common (76.8%),followed by tankless units (20.4%). Natural
gas is the most common fuel (77.8%). 16.9% have electric water heaters and 1.8% have heat pump
water heaters.
• Most respondents reported that they did not use supplemental water heating (93.5%).
46.0%of respondents reported they have low-flow faucet aerators on all faucets and 14.7%
reported having them on some faucets. Low-flow shower heads were more common—68.7%
reported having them on all showers and 10.5% reported having them on some showers.
Nearly half(47.8%) of customers that have non-electric water heating reported that they would
consider converting to heat pump water heater. Of those that said they wouldn't consider it, a small
share (7.4%)thought they would consider it if a rebate was provided, although 59.6%said they were
not sure.
• Respondents reported a high level of agreement with the statement that electricity was safe to heat
their water(average of 4.0).Agreement was lowest with statements on interest in converting to an
electric heat pump water heater(average 2.5) and that a heat pump water heater would reduce
their energy bills (average 2.9).
• For those respondents who thought electric water heating was not safe,the most common concern
was the reliability of the power system (mentioned by 33). This same concern was by far the most
common reason for thinking that electric water heating was not reliable (mentioned by 217).
Laundry
Nearly all respondents have laundry equipment in their homes (98.3%).
• Electric dryers are more common (64.9%)than natural gas dryers (33.8%). Heat pump dryers are
rare (2 respondents reported owning one).
44.2%of gas dryer owners would consider switching to electric. Of those that said wouldn't consider
it, 11.6%said they would if a rebate was offered (and 48.8%were not sure).
Kitchen
• Cooktops are common (98.4%) have them and 72.4%of customers with a cook top have a natural
gas cook top. 28.2% have an electric cooktop.
• Ovens are less common—62.5% reporting having one, however it is possible that some respondents
reporting they used a cooktop included cooktop and oven combined units. Among customers with
an oven, 54.1%are electric and 45.8%are natural gas.
• 70.5%of customers have a barbeque and 77.7%of customers with a barbeque have a propane
barbeque.
• Induction cooktops are not very common with 23.1%of respondents reporting that they have one.
Among those who do not have an induction cooktop, 73.5% believe they are aware of how they
differ from a traditional cooktop. 20.1%of respondents stated they would consider replacing their
cooktop with an induction one and 21.8%would like to learn more about them.The greatest
concern for those who would not consider induction was a belief that gas was a better fuel for

cooking (mentioned by 183),followed by satisfaction with their current equipment (mentioned by
86). Concern about service disruption was mentioned by 42.
Spas and Hot Tubs

3 Survey Methodology
3.1 Sample Design
ADM developed the sample from customer records provided by TDPUD.ADM reviewed the data and
excluded records that appeared to be businesses (e.g., contained LLC or Inc. in the name) and those that
were in the S12 E, and 1 rate schedules.
The remaining population of customers was grouped into strata based on 1)whether they were on a
primary or secondary rate schedule, and 2)their estimated annual kWh usage.The Sampled for Contact
column shows the number of unique contacts sampled for each of the strata. Contacts were sampled if
their data was complete (email and address was available), and in cases where contacts had multiple
properties, a single location was randomly sampled.

3.2 Survey Administration and Summary of Response
TDPUD customers were contacted by email to complete the survey. Customers received an initial email
in late June 2023 and a reminder email one week later. In total, 917 customers completed the survey.
The overall response rate was 9.4%and the response was somewhat higher for customers on a primary
rate schedule.

ADM utilized a technique referred to as content analysis to evaluate and categorize responses to several
open-ended questions.The process involved an examination and interpretation of these responses to
extract relevant information and discern patterns and themes.The first step was to develop response
categories based on the responses provided. Once a list of codes was developed,the codes were applied
to the individual responses. Responses received up to three codes, depending on the content of the
response. Post content coding, the frequency of each code was tabulated.

4.2 Home Ownership and Occupancy
The key findings on home ownership and occupancy are as follows:
All respondents reported owning their homes.
• Responses were roughly equally split between those who said the location was their primary home
(44.2%) and those whose home was a vacation/not primary home (52.5%). The self-categorization of
homes largely aligned with the rate schedule categorization. 94.7%of those on a primary rate
schedule reported that the location was their primary residence and 85.1%of those on a secondary
home rate schedule reported that their home was a vacation home.
• On average,the individuals reported living in their home for 16.6 years.

4.8 Water Heating
The key findings on water heating are as follows:
Standard tank water heaters are most common (76.8%),followed by tankless units (20.4%). Natural
gas is the most common fuel (77.8%). 16.9% have electric water heaters and 1.8% have heat pump
water heaters.
20.8% reported that they heat their water to more than 130 degrees.
• Most respondents reported that they did not use supplemental water heating (93.5%).
• 46.0%of respondents reported they have low-flow faucet aerators on all faucets and 14.7%
reported having them on some faucets. Low-flow shower heads were more common-68.7%
reported having them on all showers and 10.5% reported having them on some showers.
• Nearly half(47.8%) of customers that have non-electric water heating reported that they would
consider converting to heat pump water heater. Of those that said they wouldn't consider it, a small
share (7.4%)thought they would consider it if a rebate was provided, although 59.6%said they were
not sure.
Respondents reported a high level of agreement with the statement that electricity was safe to heat
their water(average of 4.0).Agreement was lowest with statements on interest in converting to an
electric heat pump water heater(average 2.5) and a heat pump water heater would reduce their
energy bills (average 2.9).
• For those respondents who thought electric water heating was not safe, most common concern was
the reliability of the power system (mentioned by 33). This same concern was by far the most
common reason for thinking that electric water heating was not reliable (mentioned by 217).
