4 1.0 INTRODUCTION has undertaken the development and implementation of an Energy Conservation and Demand Management Plan (the Plan) in accordance with Ontario Regulation 397/11. This 5 year Plan runs from 2014 to 2019, and a revised and updated Plan will be required by July 1, The Town is a small, picturesque municipality located in northern Simcoe County on the shores on Georgian Bay. It was formed in 1882 as a farming and lumber Town. Penetanguishene has a population of approximately 9,400. The area is abundant in natural beauty, known for its long secluded harbour connecting to Georgian Bay, and its expansive forests. Beyond tourism, key economic drivers include commercial retail, industry, and large health and security institutions. 1.1 PLAN STRUCTURE The structure of this Plan follows the framework laid out by Local Authority Services Energy Planning Tool. Local Authority Services (LAS) is a subsidiary of the Association of Municipalities of Ontario. The LAS framework involves 5 key steps: Commitment, Understanding, Planning, Execution, and Evaluation. Each step is outlined, in order, below. Page 1

5 2.0 COMMITMENT 2.1 DECLARATIONS is committed to the promotion of responsible energy management, through the implementation of economically viable energy efficiencies and environmental care in all municipal facilities. 2.2 VISION We are continually approaching energy management in a strategic manner allowing for the proactive pursuit of optimal energy solutions that lead to environmental, societal, and economic benefits. 2.3 GOALS To maximize the efficient use of the Town s fiscal resources. To minimize negative environmental impact of the Towns operations. 2.4 OVERALL TARGET By 2019 we will reduce the energy consumption per square foot of our municipal facilities by 15%, versus our 2012 figure. The annual target will be approximately 3% reduction per year for five years to achieve the overall 15% reduction. Reducing the overall energy consumption of the Town will also directly reduce the associated greenhouse gas emissions. 2.5 OBJECTIVES 1. To improve the energy efficiency of our facilities by utilizing best practices to reduce our energy consumption and mitigate the impact of energy cost increases. 2. To create a culture of energy conservation among the Town s staff. 3. To improve our municipal staff knowledge of energy consumption and energy conservation. 4. To reduce greenhouse gas emissions associated with our energy use. Page 2

6 3.0 UNDERSTANDING 3.1 MUNICIPAL ENERGY SITUATION uses two types of energy in its facilities: electricity and natural gas. Electricity is currently purchased through Local Authority Services (LAS) bulk purchase program. LAS, is a subsidiary of the Association of Municipalities of Ontario (AMO). The LAS program is intended to provide municipalities with a hedge against price fluctuations, and therefore save them money on electricity. Electricity for the Town is provided by two Local Delivery Companies (LDC s): Powerstream and Hydro One. Natural Gas is purchased through the LAS Bulk Natural Gas Program and delivered through Enbridge. Electricity is used in nearly all of the Town s facilities, while natural gas is used only at five (5) facilities with one additional facility set to begin using natural gas in HOW WE MANAGE ENERGY TODAY has a solid history in energy conservation initiatives. In 2008 the Town undertook the first large scale installation of LED streetlights in Ontario. The Town changed 37% of the streetlights, replacing the higher energy use metal halide and mercury vapour bulbs, with much more efficient LED technology. The Town also completed energy audits in 2009 on the Public Works Administration/Water Building and the Roads Office. The energy audits comprised of a thorough external and internal inspection of the buildings. The tools used were able to measure heat loss, air leakage, humidity/moisture issues, and identify areas requiring upgrades and repairs. Energy conservation projects completed since 2009 have been driven in part by Energy Audits and fall into the categories of lighting, heating/cooling/ventilation, insulation, windows, building envelope upgrades and motors/pumps. Projects completed to date include the following: LIGHTING UPGRADES LED Traffic signal upgrades upgraded existing traffic signals to LED fixtures (2007) LED Streetlight Pilot Program replaced mercury vapour and metal halide lights with LED streetlights Water and Roads Division garage upgraded partial lighting (2009) Library Building replaced light bulbs to more energy efficient lights (2011) Town Hall installed T8 lighting (2008) Page 3

In order to track total energy consumption, the various energy types (electricity and natural gas) have been converted into a common unit of the Gigajoule (GJ). To get an idea of how much energy one (1) gigajoule is, the average house uses gigajoules of energy in a year. One Gigajoule is equivalent to 30 L of Gasoline, 39 L of Propane, or 278 kwh of electricity. Furthermore, 1 kwh is equal to using a 100 Watt Light bulb for 10 hours. For the calendar year 2013, the Town used 3,971,089 kwh of electricity and 100,788 m3 of Natural Gas. This translates to a total energy consumption of 18,169 GJ, as shown in Table 1 below. Table 1 Total Energy Consumption 2013 Energy Source Energy Amount Converted Amount (GJ) Electricity 3,971,089 kwh 14,296 Natural Gas 100,778 m 3 3,873 Total Energy Consumption 18,169 Source: Town of Penetanguishene data Page 5

9 3.3.1 GHG EMISSIONS Each energy source has a different amount of greenhouse gas emissions associated with its use. The greenhouse gas emissions associated with electricity are derived from the way in which the electricity is generated. In Ontario, electricity is generated from a variety of sources: coal (prior to 2014) nuclear, hydroelectric dams, wind, natural gas, and photovoltaic solar. The Ontario government pledged to move away from coal power and towards renewable and with the closing of Nanticoke Generating Station in the spring of 2014, the province s electric gird is now coal-free. The greenhouse gas emissions associated with electricity use continues to decline as the province transitions towards clean and renewable energy sources. The greenhouse gas emissions associated with combustible fuels such as Natural Gas are derived from the actual combustion of those fuels. Table 2 below shows the corresponding greenhouse gas emissions associated with electricity and natural gas. Table 2 Green House Gas Emissions Factors Energy Source Emission Factor Electricity kg CO2e/kWh Natural Gas kg CO2e/m 3 Source: NRCAN Energy Conversion and Emission Factors 3.4 TRENDS IN ENERGY CONSUMPTION TRENDS IN ENERGY CONSUMPTION Table 3 below provides a summary of the Town s energy consumption. In order to be able to see overall energy use, the table shows electricity consumption and natural gas consumption in the common unit of Gigajoules (GJ), along with their more traditional measurement units of kilowatt hours (kwh) and cubic metres (m3). Table 3 Energy Trend & Profile Electricity 3,153,340 kwh 3,765,516 kwh 3,971,089 kwh Natural Gas 121,103 m3 105,905 m3 100,778 m3 Electricity Converted to GJ 11,352 GJ 13,556 GJ 14,296 GJ Natural Gas Converted to GJ 4,654 GJ 4,070 GJ 3,873 GJ Total Combined Energy Consumption 16,006 GJ 17,626 GJ 18,169 GJ As can be seen in Figure 1, the Town s overall energy use has risen over the past three (3) years. Electricity comprises the majority of the Town s energy use, with natural gas accounting for a smaller portion. Page 6

11 3.4.2 ELECTRICITY CONSUMPTION TREND All of the Town s facilities used electricity for a portion of their energy needs. The Town s electricity consumption has increased over the past three years, rising 19% and 5% respectively in 2012 and The associated electricity consumption figures were 3,153,340 kwh in 2011, 3,765,515 kwh in 2012 and 3,971,089kWh in Table 4 Electricity Consumption Electricity (kwh) 3,153,340 3,765,515 3,971,089 Percentage Increase 19% 5% NATURAL GAS CONSUMPTION TREND Five of the Town s facilities also use natural gas, mainly for heating, but also for cooking and backup generators where applicable: the arena, the fire hall, the library, the museum, and the Town Hall. The Philip H Jones Pollution Control Plant (Main Street) will be adding natural gas in The Library uses natural gas for the furnaces and air conditioners. The largest user of natural gas, the arena, uses natural gas for heating and cooking. At the arena, it is used for the following: the boiler, the HVAC system, the furnace, the seating arena radiant heaters, hot water tanks, the dehumidifier, and at the arena s snack bar. The newly constructed fire hall uses natural gas for the hot water tank and the back-up generator. The museum uses natural gas for the hot water tank only, while the Town Hall uses natural gas for its HVAC systems, and its back-up generator. Figure 3 below shows the natural gas consumption trend for each of the five buildings. Figure 3 Natural Gas Facility Consumption Natural Gas Consumption ( ) m Arena Fire Hall Library Museum Townhall *Source: Energy Consumption Data from Town of Penetanguishene Page 8

12 The overall consumption trend over the past three (3) years is downward: the Town is using less natural gas each year (see Table 5 below). While some facilities consumption has fluctuated, the largest natural gas using facility the arena has used less every year since Overall, the Town used 13% less natural gas in 2012 compared to 2011, and 5% less in 2013 compared to Table 5 Natural Gas Consumption Natural Gas Consumption (in m 3 ) 121, , ,778 Change over previous year -13% -5% GREENHOUSE GAS EMISSIONS TREND Greenhouse gas (GHG) emissions are measured in equivalent tonnes of carbon dioxide (CO2e). As outlined in Table 6 below, the Town s GHG emissions associated with facility energy use increased 7% and 2% respectively in 2012 and 2013, with the resulting GHG emissions being 576 tonnes in 2011, 614 tonnes in 2012 and 627 tonnes in [Note: 1 Tonne equals 1000 kg] Table 6 Annual GHG Emissions Combined GHG Emissions (MT C0 2 e) Change over previous year +7% +2% The total GHG emissions for each of the Top 12 buildings are shown in the Figure 4 below.

Some facilities have reduced their energy use since 2011 such as: the arena, the sewage treatment plant (Fox), the town hall, the fire hall, and the library. However, a handful of facilities have increased their energy use dramatically which resulted in an overall increase for the Town. Those facilities include: the main sewage treatment plant and the Payette pump station. The Main Street sewage treatment plan has been under construction (expansion) since The increased energy use may be associated with the construction. Page 10

The Town received provincial funding to be able to complete the replacement of approximately 37% of the streetlights. The Town installed the LED bulbs in two large installations, focusing on replacing the largest energy using bulbs, mercury vapour and metal halide. A total of 346 LED streetlights were installed in the two installations, which represented approximately 36% of the Town s total streetlights. The Town received $475,000 from the Rural Infrastructure Investment Initiative Fund to complete the installation. 3.5 RENEWABLE ENERGY UTILIZED OR PLANNED While the Town has reviewed several solar photovoltaic projects in the past, it currently utilizes no renewable energy. In addition, the Town currently has no renewable energy projects planned. Page 12

16 4.0 PLANNING 4.1 STRUCTURE PLANNING The 5-year Energy Conservation and Demand Management Plan includes both short term and mid-term strategies. Short-term is defined as years one through three of the Plan. Short-term focus areas will include: Establishing an Energy Management Team; Developing an energy consumption tracking and reporting process; Completing training and education of Town staff; Implementing no cost & low cost programs, processes, and projects; and Planning for larger expenditures in future years Mid-term is defined as years four and five of the Plan. Mid-term focus areas will be: Higher cost programs, processes, and projects 4.2 ENERGY LEADER Penetanguishene will develop a more focused effort on energy management through the creation of an energy management team. This team will be responsible for the implementation of the Plan and the review of corporate energy management strategies. The team will meet on a quarterly basis to review energy consumption reports, provide updates on energy initiatives, and discuss successes and challenges. Penetanguishene has already demonstrated initiative and progressive action with the LED Streetlight program, and Town Staff have begun to adapt and incorporate energy planning into each department. 4.3 ENERGY TRAINING Penetanguishene will train staff on energy use and energy conservation. General training will be offered for all staff, while additional, more technical training will be offered for operations staff. Natural Resources Canada s Dollars to Sense energy workshops will be considered as a training option where applicable. Page 13

17 4.4 ENERGY PURCHASING Penetanguishene will continue to purchase electricity through Local Authority Services (LAS) Electricity Program and natural gas through LAS s Natural Gas Procurement Program. LAS s program has the ability to purchase large bulk quantities for over a hundred municipalities resulting in significant savings for its participants. The Town saved 11.4% from the LAS Electricity Procurement Program from the period of July 2013 to June This translated into annual savings of $56,242, which included $6,895 savings from the streetlights accounts. During the previous 12 month period, the LAS program resulted in electricity savings of $48,020. The Town also recently signed up with LAS s Natural Gas Procurement Program, resulting in additional savings for the Town s five facilities which use natural gas. 4.5 PROGRAMS/PROCESSES/PROJECTS Energy conservation initiatives will take the form of programs, processes, and projects. initiatives to be considered over the duration of this Plan. Below is a list of PROGRAMS Continue with the ongoing implementation recommendations from the 2009 Public Works energy audits update cost and payback as necessary particularly for larger expenditure items. See Appendix A for a summary of Energy Audit Recommendations. Utilize the 2009 energy audit recommendations to develop similar initiatives in similar un-audited buildings. Investigate use of LAS free energy audit services for unaudited buildings. Continue with streetlight replacement program upgrade to LED as streetlights require replacement. Host quarterly Lunch & Learn sessions for Town staff to support the creation of a culture of conservation Investigate the possibility of participation in a demand management program to conserve energy and save money by reducing demand on the provincial electricity grid during peak periods. Develop stories/case studies of successful Town energy initiatives and share with entire Town staff and community PROCESSES Implement a process to track on a monthly basis energy use and costs for each building, and provide year over year comparative results to the operations team. Implement regular review of energy consumption data by appropriate Town staff members. Page 14

18 Utilize the LAS Audit++ and Energy Performance Benchmark Best Practice Reports as reference materials for best practices. Implement building start-up and shut-down schedules, where appropriate, and add into standard work procedure for key building personnel to eliminate waste and maximize equipment efficiencies. Ensure no build-up of dirt and dust on backside coils of vending machines and unplug them during offseason if possible. Renegotiate with suppliers for vending machine models with motion activated lighting. Use power bars on PCs and turn off at night, where possible. Make use of free cooling in summer by programming building control system to bring in 100% outdoor air at night. Turn off printers and copiers at night and on weekends, where possible. Adapt energy use to reflect Time-of-Use periods where possible. Shifting energy use to off-peak periods would use the same amount of energy but be more cost effective PROJECTS Complete an internal review of all un-audited Town buildings to confirm: type of lighting, type of heating/cooling, type of thermostats, presence of exhaust fans, presence/type/age of pumps, presence/condition of weather stripping and floor sweeps, and other equipment that utilizes energy. Continually investigate and pursue energy conservation funding opportunities, such as the Save ON Energy Small Business Lighting program. Additional potential sources of funding can be found at: Implement real-time monitoring at the highest energy use facilities. Use the baseline energy consumption data to complete benchmarking. Complete an analysis of energy demand for the various Town buildings including drivers of demand and associated costs. Install a system to automatically turn off heating/cooling when exterior overhead doors are left open. Investigate using free computer programs to automatically shut down computers when not in use. Install occupancy (motion) sensors for lights and heating, where appropriate. Enhance building envelope by replacing caulking, weather-stripping, and insulation where appropriate. Page 15

19 Install separate meters or sub-meters for facilities that are shared to allow for accurate division of energy consumption. Investigate the re-commissioning of buildings that have experienced significant change in use, space configuration, or expansion since their construction. Invest in plug-load power monitors to be shared between facilities PLANNED PROJECTS In addition to the projects listed above, Table 7 below provides a summary of energy related projects currently found in the Town s 5 Year Capital Plan.

21 5.0 EXECUTION 5.1 MUNICIPAL LEVEL On an annual basis the Town s Energy Team will develop a new Energy Action Plan, made up of a variety of programs, processes and projects. Action Plan items will be limited to one year for completion. Larger action items can be broken down into smaller steps to meet the one year timeline. By limiting actions to a single year, it facilitates forward movement on many projects simultaneously and allows for the incorporation of new information or technologies that may come available during the term of the Plan. While the Energy Conservation and Demand Management Plan is a snapshot of previously completed projects and planned energy projects, the Action Plan is essentially a to-do list. The Energy Team will implement and monitor the energy projects of the Town and will report annually to municipal council on its successes and challenges in implementing the Energy Conservation and Demand Management Plan. The Energy Team will also review and update the Plan every 5 years as legislated by the Green Energy Act. 5.2 ASSET LEVEL Once the annual Energy Action Plan is completed, it will be the responsibility of the operations team to implement the various action items. In particular, the individual(s) with responsibility for the specific buildings will be responsible for the implementation of the initiatives associated with those buildings. Tracking and reporting will be included in the implementation to allow for measurement of the impact of the actions. Facility energy use will be tracked and communicated on a regular basis to those responsible for the various assets. In addition, the department heads will review current operating practices of the facilities to ensure consistency across the Town. Page 18

22 6.0 EVALUATION 6.1 ENERGY PLAN REVIEW The Energy Management Team will review progress towards the overall goals and objectives of the Energy Conservation and Demand Management Plan on an annual basis. In addition, progress on the annual Energy Action Plan initiatives will be tracked and reviewed by the Energy Management Team on a quarterly basis. The regularly tracked energy consumption data will be used to evaluate the success of the implemented energy initiatives. To the extent possible, the costs and resulting energy and greenhouse gas savings of each energy initiatives will be calculated as part of the evaluation. The actions that were not completed by year s end will be re-evaluated for the potential inclusion in the following year s Energy Action Plan. By creating single-year Energy Action Plans, the Town will be able to adjust speed, size, and complexity of energy project based on current and future internal and external conditions. 6.2 ENERGY CONSUMPTION The total energy consumption by the municipality is represented in gigajoules (GJ). Both electricity consumption (in kwh) and natural gas consumption (in m3) have been converted into GJ for ease of comparison. As previously stated, the Town used 3,955,132 kwh of electricity and 100,778 m3 of Natural Gas in 2013, which equates to a total energy consumption of 18,169 GJ. Page 19
