CRP Home Comfort Program Overview

PGW’s LIURP, re-designed and launched in 2011

Program Goals:

• Primary – Provide cost-effective energy savings to

customers participating in PGW’s CRP

• Secondary – Reduce overall long-term cost of the CRP

as paid by all firm customers

9,092 customer installations & $8.1mm in present value net

benefits from inception to February 2015

Greatest Challenge: characteristics of PGW’s low-income

customers’ homes

Program Design

Highest usage customers on CRP assigned to program

3 program contractors (CSP) who are evaluated based on:

• Total energy savings

• Cost-effectiveness

• QA and other metrics

CSPs perform energy audits and create work scopes for

cost-effective gas savings using the PGW Program Tool

CSPs complete the installations, paid for by PGW

Auditor identified health and safety issues preventing

comprehensive weatherization.

• Seize any opportunities for savings at audit

• Set-back thermostat

• Water heater pipe wrap & low-flow devices

• CO detector

• Customer education

Health and Safety Challenges

Health & Safety issues prevent

comprehensive weatherization in at

least 37% of cases

Inefficient homes are often a

symptom of more severe structural

and mechanical problems

14

Health and Safety Partnerships

PGW coordinates with local agencies to address health and

safety improvements required for weatherization

Customers that can’t be helped by these programs are

provided a list of resources that may be of help

15

Quality Assurance & Mentoring

Program inspector focuses on training and

mentoring to capture missed opportunities

Better definitions and shared language

between contractors, customers and others

Deeper savings and cost-effectiveness

offer more flexibility for non-energy

measures
