NSTAR ELECTRIC
ENERGY STARŪ Benchmarking Initiative
The Company
NSTAR is an investor-owned electric and gas utility in
Massachusetts serving 1.3 million customers. NSTAR
was recognized by the U.S. Enviromnental Protection
Agency (EPA) in 2005 as an ENERGY STARŪ Partner
of the Year for Excellence in Promoting Superior Energy
Performance through its Benchmarking Initiative.
Goals and Objectives
NSTAR has a successful 20-year track record of deliver-
ing energy efficiency programs in the commercial and
industrial (C&I) market, including the Business Solu-
tions Program which provides technical assistance, pre-
scriptive incentives, and custom incentives to promote
efficiency improvement.
NSTAR developed the ENERGY STAR Benclunarking
Initiative to explore how benclunarking using EPA's
energy performance rating system in Portfolio Manager
could be leveraged to drive greater participation in exist-
ing programs. The goal was to shift customer focus
from one-time efficiency upgrades toward ongoing,
measured improvements in building energy performance.
It began as a pilot initiative and has continued because of
its success in increasing participation in existing incen-
tives programs.
Portfolio Manager is used as a tool for engaging custom-
ers in developing a strategic approach to energy man-
agement by considering a whole-building approach to
facility energy consumption and savings opportunities.
It is also a tool for NSTAR to work collaboratively with
its customers for sustained energy efficiency improve-
ments since customers agree to re-benchmark, tracking
energy consumption and savings opportunities over time.
Description
The ENERGY STAR Benclunarking Initiative serves 15-
25 customers each year and provides:
o Training and technical assistance in using Portfolio
Manager to measure facility energy performance and
track ongoing improvements,
o Technical assistance to identify and select cost-
effective energy efficiency opportunities.

Environmental Protection
Agency
o Guidance to match selected projects with NSTAR
incentives that are available through the existing
thirteen different C&I programs.
There are three key elements to NSTAR's successful
program delivery:
o The program is delivered as a turn-key operation by
two implementation contractors, with oversight
management provided by NSTAR staff.
Implementation contractors contact the customers,
conducting training for customer staff, produce a
facility assessment, identify savings opportunities
and identify appropriate incentives,
o NSTAR ensures cost-effective use of program
resources by providing a one-time detailed training
and technical assessment for each participating
customer. One explicit goal is for customers to
apply their new skills to conduct assessments of
other facilities in their portfolio,
o The ENERGY STAR Benclunarking Initiative
complements NSTAR's existing incentive programs
matching projects with incentive offerings.
~~ Target Customers
NSTAR targets mid-size customer facilities (over 200
kW) that are eligible to receive an EPA energy perform-
ance rating. While mid-size customers are targeted,
other customer classes, both large and small, may also
participate in the program. Program administrators focus
on customers whose billing records indicate efficiency
opportunities, and who have historically had limited par-
ticipation in NSTAR's energy efficiency programs. To
encourage participation program administrators work
with a variety of contacts at the facilities including the
customer's business manager, building engineers, and
facilities maintenance staff.
~~ Marketing/Outreach
Recruitment is initiated by NSTAR Account Executives
and Program Managers who encourage their customers
to participate. Telephone outreach is conducted to tar-
geted customers by the implementation contractors,
sometimes following an initial contact by the NSTAR
program manager. Specially developed marketing mate-
rials facilitate recruitment efforts. Customer participa-
tion guidelines were developed to outline program offer-
ings and customer responsibilities.

~~ Process
This ENERGY STAR Benchmarking Initiative uses the
EPA energy performance rating as a means for motivat-
ing customers to undertake whole building performance
improvement. Under NSTAR's management, implemen-
tation contractors provide a variety of services for par-
ticipants.
The services provided include customer recruitment,
benchmarking training for customers, and on-site cus-
tomer training that includes data entry to produce a re-
port of their facility. The program process follows these
steps:
Measure Energy Performance
Customers receive a one-time in-depth training in using
Portfolio Manager to benchmark their facility. Customers
are then trained on-site with their own facility data so
that their staff is equipped to continue benclunarking,
and apply lessons learned to their other facilities.
Identify Opportunities
An Energy Efficiency Opportunity Assessment (EEOA) is
developed by the implementation contractor and provided
to the customer. The assessment identifies operations and
maintenance measures and capital improvement measures
to reduce energy costs for the building. The EEOA in-
cludes all potential measures and analysis of all fuel
sources. The EEOA presents an Action Plan and reports a
customized strategy to assist the end-user in prioritizing
improvements. It presents savings and estimated payback
by measure. Next steps are identified for the customer,
including identification of available NSTAR incentives to
offset customer costs for implementing projects. Incen-
tives are offered through the following programs:
o Business Solutions offers comprehensive incentives
covering up to 75% of total project cost, prescriptive
incentives covering a variety of common energy-
efficient technologies, engineering services and
commissioning,
o Small Business Solutions offers upgrades to light
fixtures & controls, HVAC tune-ups, and
refrigeration controls for NSTAR C&I customers
with a demand of less than 200 kW.
o Custom Program for high-efficiency gas
technologies offers incentives for the incremental
cost for dehumidification, boilers and furnaces,
water heaters, combustion controls, chillers and
waste heat recovery.
vvEPA
o Other programs provide prescriptive incentives for
premium efficiency motors, fryers, infrared heating
equipment, and water heaters.
Provide Ongoing Support
NSTAR provides ongoing support to customers to moti-
vate them to participate in the existing incentive pro-
grams. NSTAR supports implementation by working
with contractors to monitor the impact of efficiency im-
provements, and suggests continuous energy manage-
ment system improvements.
Track Energy Use
NSTAR encourages re-benchmarking using Portfolio
Manager to track energy performance over time and
document the results of this holistic approach to effi-
ciency improvements.
Results
NSTAR continues to promote this initiative to work with
its customers to increase utilization of its existing incen-
tive programs through benclunarking.
Achievements to date (2003-2008):
o 107 buildings totaling 20.4 million square feet have
been benchmarked across all eligible space types,
o 70% of participants have taken action to improve
performance by proceeding with an in-depth
assessment, changing operational practices, or
implementing an efficiency upgrade,
o 52% of participants implemented at least one
measure identified in the in-depth assessment,
o 21% of participants have applied for incentives from
the Business Solutions Program,
o 19% have implemented comprehensive
improvements,
o 27% of participants have re-benclunarked their
facilities.
