3. Key Points
There are many ways to segment utility customer populations
Some are more meaningful than others for program design, portfolio
planning and/or EM&V
Implementers are already using segmentation to improve program
targeting (and uptake)
The EM&V community (us!) does analyze results by customer
group/segment
…But often not in a cohesive or consistent way
Consistently integrating segmentation in to EM&V will:
Deliver insights that help programs improve faster
Get stakeholders thinking about (a) how results can be used/extrapolated,
and (b) if/how programs should be tailored/targeted to different segments

4. Program implementers use segmentation all the time
Segmentation defines and divides a large population into identifiable groups
based on similar characteristics

5. Historical approach of “equal access” to programs, and
undifferentiated marketing, hasn’t yielded equal impacts
For this utility, there’s a strong relationship between wealth quintile
(measured three ways) and long-term EE program participation:

10. So, what segmentation is “good” for EM&V purposes?
1
1. Segment membership must be identifiable ex ante for all customers
Rate code (Low income, SF/MF, Small/large commercial)
Psychographic “lifestyle segment” available through data providers
(e.g., Experian)
Usage characteristics (L/M/H; summer load; load shape)
2
1. Segments should distinguish between meaningful differences that affect
program outcomes
Energy opportunity
Barriers to participation (own/rent; income)
Motivation to participate
Channel/communication preferences (on-bill, web, phone)
Impacts!
3
1. Segments should be “consumable” by readers/regulators:
Easy to understand / well-named
Manageable number

Identification: Tracking by segment requires defining segments
based on readily-available data – And we have a lot!

“Consumable” segments: Easy to explain and
interpret; manageable number
Single dimensions (single-family / multi-family) or 2X2
matrices have merit
But they leave a lot of heterogeneity undescribed
Complex segmentation schemes quickly go un-used
Reviewers don’t have background/knowledge of approach
Imagine 70 Experian lifestyle segments!
