Disclaimer: This document has been prepared by the Ontario Clean Water Agency on
behalf of the Township of Warwick in accordance with Ontario Regulation 25/23 under
the Electricity Act, 1998 for submission to the Ministry of Energy. This Plan is constantly
evolving and may be revised to reflect the most current information and circumstances.
The Township of Warwick, its council, shareholders or representatives do not accept any
liability whatsoever by reason of, or in connection with, any information in this document
or any actual or purported reliance on it by any person. The Township of Warwick may
update any information in this document at any time.

1.0 Overview
In 2014, the Township of Warwick (Township) developed a 5-year Conservation and Demand
Management (CDM) Plan in compliance with the requirements of Ontario Regulation 397/11
under the Green Energy Act, 2009. This regulation was replaced with Ontario Regulation 507/18
in 2018, and recently with Ontario Regulation 25/23 in 2023 under the Electricity Act, 1998. The
Township updated the CDM plan in 2019, under regulation 507/18.
Under Ontario Regulation 25/23, all BPS organizations, including municipalities and townships,
are required to report annually on energy use and greenhouse gas (GHG) emissions. The
organizations are also required to develop a CDM plan and update it every five years, with the
first update posted July 1, 2019. This document is the second update, which is required by July
1st 2024.
Ontario Regulation 25/23 requires public agencies to:
The Township of Warwick retained the Ontario Clean Water Agency (OCWA) to build on the
existing CDM Plan, incorporating the experiences gained and results in energy conservation over
the last five years. This updated CDM plan was developed as per the regulation and guidelines
provided by Ministry of Energy and covers the period of 2019 to 2024. The plan was presented
to the council and approved on July 8, 2024.
Report annually on energy use and GHG emissions.
Develop five-year energy CDM plans starting July 1, 2014 with the current update
due July 1, 2024.
Post annual reports and 5-year plans to the agency's website and make printed
versions available for the public.
Under Ontario Regulation 25/23, the requirements for broader public sector
energy planning and reporting are identical to those under the former Ontario
Regulation 397/11 and 507/18.
2
There are significant advantages to developing and implementing a CDM Plan. The lowest cost
options for meeting energy demands could be to implement simple energy efficiency measures.
Simple actions of turning off lights and appliances, shutting off heaters in the summer and
establishing efficient usage times, efficient production requirement, and many other actions can
result in energy savings, while providing many other environmental, economic and social
benefits, including reducing GHG emissions. Reducing energy consumption translates to
reducing costs incurred by municipalities and the savings could be directed to more important
issues in the municipalities.
The Township seeks to incorporate energy efficiency throughout all of its activities to minimize
the fiscal impact of energy on operating costs and its related environmental impacts. The
requirements of Regulation 25/23 of the Electricity Act specify that the plan is to cover only
municipal owned or leased heated/cooled facilities and facilities related to treatment of water
or sewage. Streetlights were included as they were identified in the original CDM plan and
consume a significant amount of energy. The full list of the Township's facilities included in the
CDM plan can be found in Table 1.

Notes:
1. Watford Arena was expanded to East Lambton Community Complex (ELCC) in October 2022 (increase of
floor area from 34,489 sq. ft. to 74,370 sq. ft.)
2. Watford Centennial Hall was demolished in November 2022
3. New leased downtown office online starting April 2022
4. New parking lot online starting December 2019
5. New water booster pumping station operational starting January 2019
There have been removals, additions and modifications of existing facilities at Warwick noted in
the table above. The total floor area of the largest energy consuming facility, Watford Arena,
more than doubled in size due to the expansion to the East Lambton Community Complex (ELCC)
in late 2022. Subsequently, the 1967 Watford Centennial Hall was decommissioned in late 2022
due to reaching the end-of-life. Components of this facility were included in the newly renovated
and expanded ELCC. A new-leased municipal office was included in the Township's operating
costs starting April 2022. In 2019, the new booster pumping station came online near the
intersection of Zion Line and Power Road to provide adequate distribution pressure to rural areas
of the Township. The changes to the facilities in Warwick has increased the combined operated
facility floor area by about 48,000 sq. ft. from the 2012 baseline. This has resulted in an increase
of energy consumption and will have to be accounted for in future CDM plans.
The intent of the CDM Plan is to provide a basis for the Township to implement improvements
to its infrastructure and operations that reduce energy use, their associated costs, as well as
environmental effects of the Township's activities. It is a living document that will evolve with
4
the Township's energy needs. The CDM Plan should be consistent with other existing planning
documents that relate to energy conservation. The updated CDM Plan will outline the following:
-Warwick's Strategic Plan and Corporate Energy Conservation Goals
-Completed Energy Efficiency Projects to Date
-Current and Historical Energy Results
-Renewable Energy
-Plan Implementation
-Monitoring and Evaluation
-Future Measures to Implement (2024 - 2029)

2.0
Warwick's
Strategic
Plan
and
Corporate
Energy
Conservation Goals
The Six Strategic Pillars
The Township has a refreshed Strategic Plan (2023-2026) that is built on six strategic pillars. This
represents the Township's commitment to fostering a thriving community through the
facilitation of economic development, being a strong communicator, developing strategic
intergovernmental relationships, improving & sustaining municipal infrastructure, responsible
financial stewardship, and environmental stewardship.
6
Energy Conservation Goals
To support improving and sustaining infrastructure, the Township's goal is to reduce energy
consumption in public and recreational facilities by 2% annually. This same target was established
in the original 2014 CDM plan and carried over in the 2019 update. This target was achieved in
the 2014-2019 as indicated in the 2019 CDM plan. However for the 2024 CDM plan update; there
have been significant facility additions, which has caused an increased in the total annual energy
consumption.
The Township of Warwick will allocate the necessary resources to implement the Energy
Conservation and Demand Management (CDM) Plan as required under Ontario Regulation 25/23
of the Electricity Act.
Council is committed to energy conservation and planning and will allocate resources to update
the plan as required. Staff and council will strive to achieve the objectives presented in this plan
and monitor progress on an ongoing basis. Staff and council will update the plan as required
under Regulation 25/23 of the Electricity Act or any subsequent legislation.
3.0 Completed Energy Efficiency Projects to Date
The Township has completed a number of energy conservation projects from 2014 - 2023 which
have contributed significantly to the control of energy consumption and costs. Ongoing efforts
have resulted in reduction of 24% total energy (ekWh) from 2012 to 2021. With the inclusion of
the expanded ELCC and new-leased municipal office in 2022, total energy consumption has
increased by 26% in 2023 compared to the 2012 baseline. The ELCC addition to the Watford
Arena is the driving factor for the increase in energy consumption, which comes at a trade-off for
providing a larger accessible facility for the Township and neighboring Lambton County
communities.
A list of completed energy conservation measures completed to date and from 2019 - 2024 can be
found in Table 2 below. The list illustrates the Township's leadership and commitment to actively
manage energy consumption.

4.0 Current and Historical Energy Results
This section reviews the current and historical Warwick facility energy usage. Electricity, propane
and natural gas consumption was obtained from annual Energy Consumption and Greenhouse
Gas Emissions Reporting spreadsheets, and summarized energy data provided by the Township.
A summary of the annual energy consumption for the past 5-years (2019 - 2023) and the baseline
year of 2012 is displayed in Table 3. The annual natural gas and propane consumption was
converted to equivalent energy (ekWh) to determine the total energy usage. In 2012 (baseline
year), the Township consumed approximately 2,000 eMWh (7,233 eGJ) of total energy. This was
significantly reduced in 2021, but increased due to facility additions/expansions.

As indicated in Table 3, Warwick has achieved an impressive 24% reduction in energy
consumption over the period of 2012 to 2021. Figure 1 displays the recent 5-year annual energy
consumption by all Warwick facility's for this CDM plan. The graph shows a steady decline in
energy consumption up to 2021, followed by a significant increase primarily due to the
expansions of the Watford Arena with the ELCC.

Figure 1: Total Annual Energy Consumption (ekWh) for all Reported Warwick Facilities (2019 - 2023)
Figure 2 illustrates that the Township facilities rely primarily on electricity and natural gas for
energy and heating. Propane is used at the Warwick Community Centre/Fire Hall and the
Warwick Public Works Garage. The Township is currently implementing service upgrades at the
Warwick Public Works Garage from propane to natural gas. Natural gas is both less expensive
and produces close to 20% less greenhouse gases (GHG) per BTU than propane when combusted.
Council has approved natural gas line expansion to service the Warwick Roads Garage, which is
anticipated to be completed in the fall of 2024.
Figure 2: Energy Consumption Breakdown by Fuel Type (2021)
10
Figure 3 shows the energy consumption in 2023 by building type. Community Centres consumes
the most energy (ekWh). This is followed by the fire stations and associated offices and facilities,
primarily due to significant amounts of natural gas and propane being consumed. This is evident
when reviewing Figure 4. In terms of electricity consumption (kWh) alone, the ELCC and
water/wastewater treatment facilities and pumping stations are the highest consumers.
Figure 3: 2023 Total Energy Consumption (ekWh) by Building Type
Figure 4: 2023 Electricity Consumption (kWh) by Building Type
Figure 5 breaks down the annual energy consumption for all Warwick facilities in 2012 (baseline
year), 2019 and 2023. The highest energy consumer, by a significant amount, is the newly
expanded ELCC/Watford Arena. The ELCC addition replaces the former Watford Centennial Hall,
which served as a community hall to residents of Warwick Township for over 50 years. In 2023,
the ELCC is responsible for 65% of the Township's total energy consumption. This facility offers
various sports, recreation, and leisure activities year-round and is one of the central hubs that
brings residents together.
Due to the significant upgrades to the ELCC/Watford Arena and facility additions (new leased
office, new booster pumping station etc.), it is recommended to use 2023 as the new baseline
when assessing energy savings in the next CDM plan update in 2029 (reviews results from 2024
- 2028). The energy conservation target will remain as 2% per year, which aligns with the
Township's strategic plan.
11
The expanded ELCC was designed with energy efficiency and sustainability in mind. There are
solar panels installed on the roof to offset energy costs for water heating. The building is
equipped with energy efficient lighting, a building automation system (BAS), a cool roof etc.
Despite the overall increase in energy consumption due to expansion, the new ELCC operates
more efficiently. The average electricity consumption per square foot from 2012 to 2020 was
approximately 14.8 kWh/sq. ft. This has been reduced to an average of 9.35 kWh/sq. ft. from
2021 to 2023.
Figure 5: Annual Energy Consumption for Warwick Facilities (2019 - 2023)
The Watford Sewage Lagoons saw a significant decrease in energy consumption since 2012 (over
50%) by utilizing VFDs on the mechanical surface aerator motors in late 2018. In August 2023,
the IPEX Vortex Aerator pilot program commenced where one unit was installed into the lagoon.
The mechanical surface aerators are intended to be replaced with IPEX double vortex aerators
through this pilot study. These units provide aeration to the lagoon much more efficiently and
further energy savings are expected. In February 2024, two more IPEX units were installed in the
lagoon. The exiting VFDs are utilized on the motors of the new IPEX units.
Various streetlights in the Warwick and Watford area have been upgraded to energy efficient
LED lighting. This has resulted in actual annual energy savings of over 100 MWh since 2012.
There are several older facilities that were constructed from 1885 to 1982 such as the Watford
Roads Garage, Watford Museum/Old Fire Hall, Warwick Public Works Garage, Warwick Fire
Station etc. It is important to maintain the structural integrity of the buildings and their
components. Compromise to the building envelope will lead to increased energy usage and costs
to provide heating. In 2019, the Township completed facility condition assessments and
12
identified improvements in their long-term capital budget. The next condition assessment is
planned for 2024 and will include a climate change component for all facilities.
5.0 Renewable Energy
Renewable Energy Utilized or Planned:
Renewable energy is generated from natural sources such as sunlight, wind, and geothermal heat.
Currently the Township has implemented a rooftop solar water heating system at the new ELCC.
The solar panels were commissioned in March 2023. The system is designed as a preheat for the
conventional water heating system to offset the energy requirement for heating domestic water.
The roof at the ELCC was constructed to support additional solar panel loads. At the time of
construction in 2021/2022, grid capacity and grants were not available to support the additional
solar panel installation. Implementation of additional solar panels at the ELCC is a potential future
project.
Besides additional rooftop solar panels at the ELCC, the Township does not currently have any
plans for other new renewable energy generation for 2024 - 2029 at this time.
6.0 Plan Implementation
Ontario Regulation 25/23 promotes increased municipal energy management and engagement.
The main driver for municipalities to change the way energy is used relates to fiscal benefits and
financial incentives. Energy is a manageable input to the business process, much like any other
resource cost. Warwick is maintaining and developing current and planned services that continue
to be affordable to taxpayers.
Current practices must be enhanced and new approaches must be developed. To meet these
needs, the Township will consider designing a comprehensive program for collecting and
analyzing monthly energy billing information, and ensuring that staff is informed about energy
consumption. The resulting energy costs and consumption database will be used to monitor
excessive variations, target facility follow-up assessments, and determine areas that could be
This CDM Plan provides the "big picture" view as an ongoing framework for optimizing overall
energy use and achieving success.

Do
candidates for improved conservation. These monitoring enhancements will improve Warwick's
understanding of the bottom line impact of energy management.
In order to establish a baseline for managing energy costs, the Township has captured
information critical to energy management planning. This formalizes the process involved in
understanding the relative magnitude of energy costs, the possible ways to reduce energy use,
energy targets that are likely to be achievable, and other associated activities that need to occur.
CDM Planning is intended to be a process of "continuous improvement." The Township follows
NRCAN, ISO 50001's four step plan-do-check-act management methodology, used in business
for the control and continuous improvement of processes.
PLAN
Establish the energy conservation objectives and processes necessary to deliver results in
accordance with the expected outputs: the energy conservation targets or goals. Start on a small
scale to test possible effects and financial feasibility. Develop an Energy Conservation Demand
Management Plan prioritizing budgets, resources, and timelines.
Act
Check
14
DO
Implement the plan and collect data for analysis in the following "CHECK" and "ACT" steps.
Develop projects' design and execution, preparing status reports, and implementing the
communication strategy.
CHECK
Study the actual results (measured and collected in "DO" above) and compare against the
expected results (targets or goals from the "PLAN") to ascertain any differences. Evaluate any
deviations in implementation from the plan and evaluate the appropriateness and completeness
of the plan to enable the execution, i.e., "Do".
ACT
Recommend improvements and adjustments to the initial plan; determine the course of
corrections and modifications to the plan.
The Township implements tools to maintain and continually improve energy conservation and
demand management. Benchmarking is the process that the Township has implemented for
collecting, analyzing and relating energy performance data of comparable activities to evaluate
and compare performance between or within entities.
The detailed energy conservation project planning process is visually illustrated below.

7.0 Monitoring and Evaluation
We will review and evaluate our energy plan, revising and updating it as necessary, on an annual
basis within our corporate planning process.
Annual Energy and GHG Emissions Reporting and Five-Year Plan Update
Ontario Regulation 25/23 requires that the Township of Warwick report on the results of the
CDM Plan at the end of the five-year planning period. As in this update, in the next update due
in 2029, the Township of Warwick will provide an update to include any revisions to the current
CDM Plan. The Township of Warwick has submitted and published all of its annual Energy and
Greenhouse Emission Reports and will continue to do so annually until the next CDM update. At
that time, the revised Plan will provide:
-
A description of current and proposed measures for conserving and otherwise reducing
energy consumption and managing its demand for energy;
-
A revised forecast of the expected results of the current and proposed measures;
-
A report of the actual results achieved;
-
A description of any proposed changes to be made to assist the Township in reaching
any targets it has established or forecasts it has made; and
-
Any additional Council initiatives geared at achieving or establishing new targets.
8.0 Future Measures to Implement (2024 - 2029)
A critical part of any plan is the detailed list of specific actions needed to achieve the desired
goals and objectives. The Township of Warwick has developed a list of key projects, which will
help meet the energy reduction goals set out in our Strategic Plan (see Section 2.0). As discussed
in Section 4.0, it is recommended to use 2023 as the new baseline year due to the facility changes
at Warwick.
The following is a list of future planned energy conservation measures and considerations to be
implemented from 2024 - 2029:
