7 HISTORICAL BACKGROUND The Public Works, Office of Energy Initiatives (OEI) was established in 2006 and on November 14, 2007 Hamilton City Council approved the City s first Corporate Energy Policy (PW07127). Part of this policy included annual reporting on the progress and results of the Corporate Energy Policy Initiatives including facts with respect to key performance indicators, including but not limited to consumption per square foot, cost per square foot for natural gas and electricity and CO2 2 emission reductions. As stated in the Policy, the key to a successful long term energy conservation and demand management vision is a strong Energy Policy with measureable and achievable targets. To that end, the Energy Policy calls for targeted energy reductions in energy intensity of City owned facilities and operations of: 3% by % by % by 2020 The reduction targets are measured against the base year of The target is compared Corporately and to each City Department or Division s overall energy consumption. //6 Providing services that bring our city to life!

9 EXECUTIVE SUMMARY The City of Hamilton s Corporate Energy policy is specifically designed to facilitate the achievement of City wide energy reduction targets, provide for ongoing energy monitoring and targeting of utility usage and defining policies regarding capital investment related to energy. The Energy Policy calls for targeted energy reduction in energy intensity of City owned facilities and operations of 20% by This target equates to about a 1.5% reduction in energy per year. This Corporate Energy report highlights the substantial cost and energy saving measures implemented throughout the year. Efforts taken by staff in various City departments from previous years produced an 8% reduction in overall energy consumption as of the end of As of the end of 2010, continued efforts by the City now have the overall energy reduction sitting at 13%. These energy reduction initiatives in conjunction with a utility management plan have thus resulted in a cost saving and avoided cost total of $17 million. While many of these initiatives include measures that yield permanent and sustainable reductions in energy use, it is worthy to note that this 13% reduction in energy is not adjusted for weather related influences and in future years, may be subject to change in the event of significant abnormal weather conditions. The greenhouse gas emissions reduction, associated with this cumulative reduction in energy use, amounts to 18,589 tonnes of CO 2. That has the same effect of removing 3,500 cars from Hamilton City streets. //8 Providing services that bring our city to life! MacNab Street Bus Terminal

13 This Corporate Energy Report provides a summary of energy and cost savings throughout City departments, boards and agencies as a result of energy savings, commodity purchases, incentives and rate optimization. The Report gauges how the City is performing against previously established corporate and environmental targeted reductions of 20%. As part of the City s energy policy, the Office of Energy Initiatives is responsible for tracking and reporting on energy results based on key performance indicators. The Corporate Energy Report demonstrates that Council s decision to centralize responsibility for energy management thorough the Office of Energy Initiatives has resulted in significant cost savings, innovation and sustainable energy practices. To continue to meet and exceed targets set by the Corporate Energy Policy for 2011 and beyond, the City is pursuing several new initiatives including; Complete lighting retrofit of all the City libraries using energy efficient lighting Completion of the Downtown District Cooling Loop project Complete lighting retrofit, including lighting controls at Copps Coliseum to increase efficiency and reduce consumption Improvements to Water and Wastewater high lift pumping stations which will reduce electricity consumption by approximately 35%. Additional energy retrofit projects at arenas, firehalls, the operations centre at 330 Wentworth and the Hamilton Convention Centre Procurement & Rates Incentives & Cost Recovery Energy Efficiency Measures $17.0 Million Cumulative Cost Benefits Staffing Cost of $1.5 Million In order to provide a cost benefit overview for Council, the ongoing costs incurred to date by the Office of Energy Initiatives are presented against the aggregate savings up to year end This clearly depicts the benefits are exceeding the costs and certainly surpassing any expectations originally presented when the group was formed. Councils continued commitment to developing strategies that decrease energy costs and energy usage will lead to additional cost savings and a reduction in related CO2 2 emissions that impact on the environment. //12 Providing services that bring our city to life!

15 As of year end of 2010 the City s overall energy consumption has decreased by 13% from the base year, and is well ahead of the targeted reduction defined in the City s Corporate Energy Policy. As a direct result of these reductions in energy use, the corresponding reduction in Green House Gas (GHG) emissions represents a cumulative total of 18, 589 tonnes of CO 2. This is close to an equivalent of 4,000 acres of forest or removing 3,500 cars from the road. The vast majority of the work implemented to date has been completed by local firms that have won these bids, thereby providing jobs within our community. Further, the work is sustainable and can be replicated which provides additional stimulus in the coming years. Many of these jobs are considered green jobs as they relate to projects that reduce GHG s and promote energy efficiency Emissions Reductions from CDM Projects Tonnes CO2 CDM (Conservation & Demand Management) HG //14 Providing services that bring our city to life!

17 While the aggregate performance is good to track for general performance indicators, the tabled sub groups are provided for more detailed performance tracking purposes. The sub groups are each responsible to contribute their own share towards the stated Corporate Energy Policy targets of 20% energy intensity reduction by These groups each have their own unique challenges to meeting these targets - some sites are more weather dependent (general office space), others sites are more dependent on activity levels (Arena s, Recreation Facilities). Of course some sites are not listed at all as they have no relevant cost or consumption per square foot (Water and Wastewater). The latter group continues to contribute to the overall targets in other ways with their own efficiency projects or rate optimization opportunities.

19 ENERGY MARKETS Electricity and natural gas markets are both subject to vast swings in costs due to market volatility brought about by market dynamics such as supply and demand, weather, the value of the Canadian dollar and global politics. In addition to these factors, increases for the regulated portion of the price of energy approved by the Ontario Energy Board add yet another layer of cost to our energy supply. To mitigate the exposure to price volatility, the Office of Energy Initiatives has implemented several procurement strategies that has controlled the price for energy and continues to be a significant contributor to the success of the Corporate Energy Policy. While the City has put in place mechanisms to help control the variable costs of energy, there are no mechanisms available to deal with rising costs in the regulated portion as is the case for electricity where the price for electricity is made up of a regulated component and an unregulated component. The regulated component consists of transmission and distribution charges plus variable Global Adjustment charges whereas the unregulated portion or commodity portion is comprised of the market price often referred to as the Hourly Ontario Energy Price. These two key components are added together to make up the variable price that electrical energy is charged as shown below to which the transmission and distribution charges are added to produce the full delivered price for electricity. The impact of the Global Adjustment, as seen in the chart below, illustrates how the recent trend of increasing Global Adjustment prices adversely offsets the declining market prices and the significant portion of the combined energy price it represents. While significant efforts are made to reduce consumption some of the financial benefits are not realized due to these increasing regulated costs. In the natural gas energy market, recent economic trends have eroded the demand for natural gas and the advancement of techniques for extracting shale gas formations has created favourable conditions for natural gas consumers. The City of Hamilton through its own procurement strategy has faired well in comparison to other municipalities that participated in other prescribed purchasing arrangements. The commodity purchasing strategy coupled with management of utility rates has produced a cost benefit of $9,050,000. These efforts represent almost 53% of the cumulative cost benefits derived through the actions of the Office of Energy Initiatives. Other elements include $3,050,000 through energy conservation measures plus $4,900,000 through incentives and billing recovery. The combined cost benefit for all three initiatives as of the end of 2010 is $17,000,000. //18 Providing services that bring our city to life!

33 u CORPORATE ENERGY USAGE Energy consumption for 2010 declined by 5.4% from last year s level which is a direct result of the various energy conservation measures undertaken by the City and the overall target of 20% for 2020 now sits at 13%. The overall spent on electricity and natural gas of $25 million is a decrease of $1.29 Million, or 5% from last year s spend. In relation to our base year of 2005, energy spending is down 7.5%. //32 Providing services that bring our city to life!

35 a COMPARISON OF ANNUAL KPI A review of electricity and natural gas consumption and cost serves as a Key Performance Indicator of the highest level. The 2010 comparisons of last year and base year totals, show both consumption and cost are trending in a positive direction. While mild winter weather contributed to a reduction in natural gas requirements, rising electricity prices offset gains created by a reduction in electricity use. //34 Providing services that bring our city to life!

37 s ENERGY COST SAVINGS AND AVOIDED COST BENEFITS This years reporting of Energy Cost Savings and Avoided costs are again stated in cumulative fashion and broken out into three areas: Levy Benefits benefits or reductions reflected in the tax base; Rate Benefits benefits or reductions to the water rate base; Corporate Benefits total combined savings and benefits (Levy + Rate) Avoided Cost refers to the total cost avoided by the City through a reduction in energy rates. It is the capital or expense that would have had to be paid if the project or action did not proceed and yields financial benefit to the City. Direct Savings are savings that directly benefit the City through levy or rate savings, such as incentives and billing recoveries. //36 Providing services that bring our city to life! Albion Falls

39 p KEY PERFORMANCE INDICATORS Tracking and reporting on energy use and cost per square foot, provides a meaningful method for validating the effectiveness of the City s Energy Management program and initiatives and serves as a means to ensure energy continues to be used efficiently. To accurately report on energy intensity, the Office of Energy Initiatives uses equivalent kilowatt-hours as the unit of measure. This unit is calculated by converting cubic meters of natural gas used to kilowatt-hours and adding in the electricity used. As for energy intensity cost, both energy streams are added dollar for dollar and allows for a straight forward analysis of energy cost per square foot. Total square footage reported on for 2010 remains virtually unchanged from 2009 levels. Data does not include Housing, Water and Wastewater, Operations and Maintenance. These services are process oriented thus intensity per square foot is not relevant. //38 Providing services that bring our city to life! Stoney Creek East End Police Station

41 e ENERGY INTENSITY COST AND CONSUMPTION While electricity prices trended upwards through out 2010 due to increased regulatory charges and rising Global Adjustment charges, natural gas prices declined primarily due to a favorable supply to demand balance and an effective procurement strategy. In relation to the base year 2005, the aggregate energy cost per square foot for Public Works decreased over 15% in 2010, with all of the main service areas showing improvement ahead of the Corporate Energy Policy Target. In each of the main Public Works service areas, energy use intensity showed continued decline from 2005 levels as well a decline from previous years levels. The overall equivalent kilowatt-hour per square foot intensity level sits at a 16% reduction from 2005 base year levels. The energy intensity KPI for each service sector reported here is ahead of target and with continued efforts to reduce Bayfront Park energy use planned over the next several years, expectations are to meet and surpass the 20% target outlined in the Corporate Energy Policy. While electricity unit prices increased in 2010, the efficient use of energy (natural gas and electricity) together with a decline in natural gas pricing combined to produce a successful year for the City. //40 Providing services that bring our city to life!

43 c ENERGY CONSERVATION AND DEMAND MANAGEMENT INITIATIVES-2010 Energy conservation initiatives refer to projects that reduce energy consumption by using more efficient technologies. Demand management refers to initiatives that reduce peak electricity usage or peak kilowatt demand conservation and demand management activities (abbreviated as CDM) contributed incremental savings of $1.84 million dollars bringing the cumulative total to $4.93 million dollars. The following pages highlight 2010 and future CDM projects. The City s District Cooling Project (Phase 2) added City Hall onto the district loop, new chillers at the Central Library/ Farmers Market and a connection to the Lister Building. When completed, the new $10M district cooling system will use 41 per cent less energy per year, resulting in annual utility savings of $181,000 and a 556-tonne per year reduction in harmful CO 2 emissions. Downtown City Hall Renovations implemented multiple energy efficiency improvements that will reduce energy consumption by 35%, water consumption by 15% and reduce GHG emissions by over 50%. Measures include lighting, energy management, district heating/ cooling, window, envelope, pump, fan and water upgrades. Copps Coliseum energy efficient lighting and control system will save over $100,000 in energy costs. L.E.D Street Lighting pilot project was completed on Vine Street as part of an ongoing initiative. //42 Providing services that bring our city to life!

45 r HAMILTON RENEWABLE POWER INC. The City of Hamilton created Hamilton Renewable Power Incorporated in 2005 for the purpose to construct, operate and maintain a renewable energy cogeneration facility. In doing so, Hamilton was the first municipality in Ontario to be accepted by the Ontario Energy Financial Corporation to build a generator for sustainable green energy. By producing green renewable energy (Biogas) from a waste source (methane) these systems reduce greenhouse gas emissions, increase energy efficiency at the Wastewater Treatment Plant, produce revenue and reduce operating costs by generating electricity and utilizing waste heat. With a combined generating capacity of 4,800 kilowatts the renewable generating system at Glanbrook Landfill and the RENEWABLE Woodward Wastewater Treatment Plant have created an annual benefit close to $2 million to the City of Hamilton and together have reduced CO 2 emissions by 106,500 tonnes per year. //44 Providing services that bring our city to life!

47 f FUTURE ENERGY CONSERVATION INITIATIVES City-Wide Energy Efficiency Projects Building on the success of previous energy efficiency projects such as the 2008 Energy Retrofit Pilot Program and 2009/10 20-building Public Library retrofits, council approved a funding request on October 4th, 2010 for City-wide energy efficiency retrofits to lighting and control systems in Fire Stations, Arenas, the Wentworth Operating Centre and the Hamilton Convention Centre. At Macassa Lodge, a water conservation project will be implemented to reduce water usage and costs. Water and Wastewater infrastructure project for the High Lift Pumping Station. Initial estimates of 35% savings or $450,000 in annual electricity savings Completion in Arena - Lighting & Controls Working closely with the Recreation Division, this project would improve arena lighting and reduce energy consumption. Twelve arenas will be upgraded to more efficient lighting systems which will aid in improving and standardizing the lighting levels across city arenas. Fire Stations - Lighting & Controls Involves the installation of energy efficient lighting and controls in the Fire Stations. More efficient lighting along with the use of motion detectors would ensure lights are turned off when rooms are unoccupied. These controls would also prevent energy waste from heating/cooling operations when outside doors are left open. In many cases a 15-20% reduction in energy consumption is expected to be achieved. Maccassa Lodge - Water Conservation By installing more efficient toilets throughout the facility, the lodge will benefit from significant water usage reductions. This water savings project has been proven through past water consumption projects previously completed in Housing. Wentworth Operating Centre - Lighting & Controls The Wentworth Operations Centre is a mixed use facility which includes the City s Primary Fleet operations, Darts and various office spaces. The large bay areas have many lighting fixtures that can be turned off when nobody is present. The use of motion detectors will reduce this energy waste when nobody is in the area. Office area would be upgraded to more energy efficient lighting. It should be noted this work is in addition to work previously completed under the Energy Retrofit Pilot Program completed in These additional energy savings will compliment the numerous measures already in place at this facility. Hamilton Convention Centre Lighting & Controls This project would include installation of more efficient lamps and ballast combinations and better control measures such as occupancy sensors and daylight harvesting systems. //46 Providing services that bring our city to life!

48 Community Services Arena infrastructure projects Two arena projects slated for completion in 2011 will use significantly less energy than current systems. The North Wentworth Twin Pad Arena Project and the Morgan Firestone Arena Twinning have incorporated key design characteristics which will provide for superior energy performance. The design incorporates energy efficient lighting, low flow faucets and heat recovery from the refrigeration system that will provide a total energy savings of approximately 40 percent. Additionally the North Wentworth Twin Pad Arena Project design has included a ground source heating and cooling system that will provide additional energy savings totalling 59 percent as compared to traditional arenas. The LEED Silver project will be the first City of Hamilton arena to receive the designation. Hamilton Public Libraries will install comprehensive lighting redesign and control system retrofits Completion in 2011 Many of the energy efficiency projects previously implemented or about to be implemented in 2011 represent important savings in the area of lighting systems. This is significant as these types of electrical loads are not weather dependent and therefore represent sustained, permanent savings going forward MacNab Street Bus Terminal Green Roof Project The City of Hamilton Energy Report //47
