Let’s Talk Energy Savings:
The City of Norwalk partners with Conservation & Load Management
(C&LM)
Mayor Alex KnoppNovember 18, 2004
ChallengesFederal:
Federal Energy Regulatory Commission (FERC) ranks SouthWest Connecticut as one of the nation’s top ten reliability risks.
State:The CT Energy Advisory Board (CEAB) stated “…to ensure a balanced energy future – including the continued development of competitive markets, promotion of the greater use of renewable energy and energy efficiency…”
Local:From Mayor Knopp’s October 2, 2003 Press Release: “ …energy initiatives are part of my “smart government” management reforms to reduce city expenditures by giving taxpayers increased value for each dollar spent. …”
Partnership in 2004
In 2004, the City of Norwalk and CL&P “partnered” in the Community Based Program which is a Conservation & Load Management Fund initiative.
The goal of the program is to promote economic development in the community, advance the efficient use of energy, improve the environment and to raise awareness about the community’s specific energy needs.
The target audience is Norwalk’s CL&P customers, such as Municipal, Commercial and Industrial, Residential and Schools.
Norwalk has learned that partnership between a municipality’s consumers
and the utility companies
is critical to achieve the next level
of energy conservation.
Conservation & Load Management
“Partnership” at WorkC&LM coordinated an Energy Fair atthe largest employer in Norwalk – theNorwalk Hospital.
The Event was supported by the City,Hospital, and Chamber of Commerce.
The Event provided energy awarenessinformation to employees and visitorsand also offered energy efficientbulbs and lamps for sale at greatlyreduced prices (which are subsidizedby the CT Conservation Fund).
CL&P’s efficiency programs are funded by a conservation surcharge on customers’ electric bill, which forms the basis of the Connecticut Energy Conservation and Load Management Fund (Fund).
The Fund was created by the State Legislature to allow the State’s utilities to provide cost-effective energy conservation programs and market transformation initiatives.
The Energy Conservation Management Board (ECMB) was created by theState Legislature to advise the State’s utilities as they develop and implement
theirC&LM programs and initiatives.
The Connecticut Department of Public Utility Control (DPUC) regulates the utilities’ C&LM programs.
CONSERVATION & LOAD MANAGEMENT (C&LM)
Municipal Buildings Program
-Identifies projects that typically would not have been implemented without this program-Available to all CL&P Municipalities-Installation provided by CL&P approved vendors and contractors
Incentives: Up to 75% of project cost in 2004 50% of installed cost in 2005 (anticipated) 0% Interest Loans available

2003/04 C&LM Activity
The City of Norwalk has participated in a significant number
of C&LM projects which has all ready delivered more than
$500,000 in incentive payments to the City for including
energy efficient practices and equipment in city projects.
These energy conservation projects will save the City
approximately $115,000 annually on its electric bill or
approximately $1.7M over the life of the energy efficient
measures installed.

*projected incentive amount
Conservation & Load Management
Norwalk City Hall Atrium
Total C&LM Incentive=$39,046
Replaced 200 lights requiring 200
watts per fixture to lights that only
require 150 watts.
Projected annual savings to the City of $8,457.
Norwalk Main Library
Total C&LM Incentive=$104,143
Replaced existing lighting fixtures.
This gave a 40% reduction in wattage
and an estimated annual savings of
$43,066.
Monitoring and control devices installed
provided an estimated annual savings of
$2,500.
Brien McMahon H.S.
Total C&LM Incentive=$230,837*
Total approximate kWh Savings:Annual = 1,163,563Lifetime = 20,757,797
Total estimated cost savings:Annual = $ 93,085Lifetime = $1,660,617
* Projected Incentive for 2005/06
Demand Reduction Program Projects
By using incentives offered
by C&LM, Nxegen added
controls to water coolers and
vending machine to cycle
refrigeration compressors off
during off-peak hours.
Estimated Annual Savings
Per machine = $650
Nxegen’s Real-Time Monitoring System
Provides valuable usage and cost
information .
Able to identify inefficiencies in
usage patterns and provide monthly
savings reports.
In 2003, these devices conserved
approximately 72,752 kWh with an
estimated savings of $6,548.
ISO-New England Project
The City of Norwalk entered into a four-year agreement with power grid operator ISO-NE with four (4) emergency generators:
-City Hall with a committed capacity of 100kW- Public Works Center with a committed capacity of 100kW- Two (2) at the Waste Water Treatment Plant with a total committed capacity of 700kW.
Based on the total committed capacity of 900 kW, the City expects to earn $97,200 in revenue this year, plus the added compensation for operating costsduring an actual load-shed event.
During the first year of the program, Norwalk actually shed 1030 kW and is tryingto get ISO-NE to increase the committed capacity to 1000kW. If that happens,Norwalk could earn as much as $108,000 plus operating costs.
Norwalk leads the way
The City recognizes the importance of broadening its energy conservation reach beyond these programs and is also working with SNEW and othersto improve the City’s overall energy efficiencies.
The City will continue to look into the energy marketplace and learn new technology and management techniques that will further reduce ourenergy demand, help our City, and continue to move Norwalk forward.
