2015 Performance


In 2015, we consulted internally and externally on our role in the transition to a lower-carbon future, and used the feedback we received to update our corporate Climate Policy, which provides enterprise-wide guidance and standards on how we are responding to climate risks and opportunities.

In 2015, our Chief Sustainability Officer served on the Alberta government’s five-member Climate Advisory Panel, whose mandate was to review Alberta’s existing climate change policies, engage with Albertans and provide Alberta’s Minister of Environment and Parks with recommendations on how to reduce the province’s GHG emissions.

In 2015, we publicly supported new carbon pricing policies in Alberta, Quebec and Ontario.

Cumulatively, between 1995 and the end of 2014, our DSM programs saved approximately 9.6 billion cubic meters of natural gas and reduced carbon dioxide equivalent emissions by 18 million tonnes.

Reduce GHG Emissions

Our GHG Emissions Targets

We recognize that climate change is an important issue, and are focusing on reducing our own operational carbon emissions in Canada through business segment-level targets.

In 2005, we achieved our initial target to reduce the direct GHG emissions that result from our Canadian operations by 15 percent below 1990 levels and, in fact, achieved an 18 percent reduction. We subsequently set a new 2010 target to reduce our direct GHG emissions that result from our Canadian operations by 20 percent below 1990 levels and, in 2011, determined that we had in fact achieved a 21 percent reduction.

In 2015, we assessed the feasibility of setting a multi-year, corporate-wide target for carbon reduction and energy efficiency improvements that each business segment could implement.  Our assessment involved reviewing our business segments’ emissions and energy use profiles, finding opportunities for operational improvements and discussing the potential for establishing an intensity-based target with a common metric for the entire company. In 2016, we plan to develop business segment-specific Carbon and Energy Efficiency (CEE) plans, which will serve as the foundation for an enterprise-wide target.

Our Direct GHG Emissions (Scope 1)

The graph and table below show the direct, or Scope 1, emissions for our GPP&ES, LP, GD and Corporate business segments, as well as for our GPT&ET groups. Scope 1 emissions include the emissions (fugitive, combustion, vented) that result from activities associated with our company-operated facilities, buildings and leased offices, as well as from our company-operated vehicles and aircraft.

Scope 1 GHG Emissions
Scope 1 (t CO2e) 2012 2013 2014
Liquids Pipelines (LP) 1 19,000 121,0002,3 56,0003
Gas Pipelines, Processing & Energy Services (GPP&ES) 2,559,000 2,273,000 1,899,000
Gas Distribution (GD) 293,000 301,000 328,000
Green Power, Transmission and Emerging Technology (GPT&ET) 500 100 1004
Corporate 2,000 2,000 2,000
Total - Scope 1 2,874,000 2,698,000 2,285,000
  1. Our Scope 1 estimates for our LP business segment in the U.S. include vehicle emissions and fugitive emissions from terminal operations (CH4 and CO2), as well as stationary combustion-related emissions from pumps, heaters, emergency generators and vapor destruction units. Currently, our Scope 1 emissions inventory does not include emissions that result from space heating, water heating and other small combustion sources. These emissions sources, however, are minor in terms of our LP U.S.’s total Scope 1 and 2 emissions profiles.
  2. In 2013, we used SF6 as a tracer gas when we conducted hydrostatic testing of Line 14. The CO­2e of the test (84,800 t) encompasses approximately 74 percent of LP’s 2013 Scope 1 total.
  3. 2014, LP’s Scope 1 GHG emissions are higher than usual due to its temporary use of diesel-fueled generation for new pumps. We have adjusted the 2013 data to account for the temporary diesel-fueled generation that also took place in 2013.
  4. We have estimated that GPT&ET’s 2014 Scope 1 emissions are equal to its 2013 Scope 1 emissions.

From an enterprise-wide perspective, our Scope 1 2014 GHG emissions decreased approximately 15 percent from their 2013 levels.

From a business segment perspective, LP’s Scope 1 emissions were higher in 2014 than they have been in the past due to LP’s increased use of a fuel in thermal oxidation unit and to its temporary use of diesel-fueled generation (LP uses diesel-fueled generation when grid power is not yet available for new pumps). In addition, LP’s 2013 Scope 1 emissions were atypical because it used sulfur hexafluoride (SF6) as a tracer gas when it was hydrostatically testing an extensive length of pipeline for leaks. We are supporting research into the use of SF6 alternatives for pipeline leak detection that are less GHG intensive.

GPP&ES’s Scope 1 emissions are directly proportional to its system throughput and gas processing volumes. As such, GPP&ES’s lower 2014 Scope 1 emissions (compared with 2013) are the result of lower system throughput and gas processing volumes that year.

GD’s Scope 1 emissions rose in 2014 over its 2013 levels due to the increased volume of fuel it used at its underground storage operations. GD’s fuel use varies depending on the amounts of natural gas it injects or removes from its storage facility. Also, GD’s 2014 fugitive emissions increased because it has adopted a higher emission factor for calculating that emissions that are caused by damages to its natural gas pipelines.

GPT&ET’s 2014 Scope 1 decrease was mainly due to the fact that it had decommissioned its natural gas-fired fuel cell.

Corporate’s GHG emissions have remained fairly consistent from 2012 to 2014.

Our Indirect GHG Emissions (Scope 2)

The graph and table below show the indirect, or Scope 2, emissions for our LP, GPP&ES, GD and Corporate business segments, as well as for our GPT&ET group. Scope 2 emissions include the emissions that result from the off-site generation of electricity, which we buy and consume. We do not purchase heating, cooling or steam energy for our operations.

Each year, we calculate our Scope 2 emissions using the most current Environment Canada or U.S. EPA e-GRID grid-average emission factors. As such, the year-over-year changes in our Scope 2 emissions data may reflect, not only changes in our electricity consumption, but changes in the emission factors that we have used to calculate our emissions.

Scope 2 GHG Emissions

Scope 2 (t CO2e) 2012 2013 2014
Liquids Pipelines (LP) 2,781,000 2,835,000 3,731,000
Gas Pipelines, Processing & Energy Services (GPP&ES) 208,000 212,000 204,000
Gas Distribution (GD) 2,900 2,400 2,200
Green Power, Transmission and Emerging Technology (GPT&ET) 1,300 1,700 1,7001
Corporate Services 2,400 2,600 2,600
Total – Scope 2 2,995,000 3,054,000 3,941,000
  1. We have estimated that our 2014 Scope 2 emissions for GPT&ET are equal to its 2013 Scope 2 emissions.

From an enterprise-wide perspective, our Scope 2 2014 GHG emissions were approximately 29 percent higher than they were in 2013. This increase is due in large part to LP’s increased electricity use. LP uses electricity to operate the pumps that push crude oil and other liquid petroleum products through its pipelines. LP’s electricity use has increased as the volume of the product it delivers through its pipelines has increased.

Our Indirect GHG Emissions (Scope 3)

Under its G4 guidelines, the Global Reporting Initiative describes indirect GHG emissions as the emissions that result from an organization’s activities, but that occur at sources not owned or controlled by the organization. We do not yet assess all of the indirect GHG emissions that result from our activities because such an assessment would entail a significant analytical effort. We do, however, intend to expand on our Scope 3 emissions reporting in future CSR and sustainability reports. Here we provide only the following Scope 3 GHG emissions:

The GHG Emissions that Result from Our Customers’ Natural Gas Use - In the following table we provide a high-level estimate of the Scope 3 emissions that resulted from our customers’ use of the natural gas that GD distributes or sells through its natural gas utility subsidiaries. For simplicity, we have assumed that all of the natural gas that GD sold was combusted.

Scope 3 GHG Emissions from Customer Use of Natural Gas (t CO2e)

2012 2013 2014
20,300,000 22,700,000 24,100,000

Our annual Scope 3 GHG emissions increases are the result of GD adding approximately 35,000 new natural gas customers in 2013 and 2014. The higher emissions in 2014 are also due to the fact that 2014 was colder than 2013 and 2012.

The GHG Emissions that Result from Grid Loss - In the following table, we provide a high-level estimate of the Scope 3 emissions that resulted from the loss of electricity during its transmission and distribution (grid loss). To calculate the estimate we applied the applicable country’s most current grid loss percentages to our Scope 2 data. 

Scope 3 emissions from grid loss vary from year to year depending on a number of factors, including the amount of electricity purchased, the emissions intensity of the purchased electricity and the percentage grid loss factor, which can vary between electricity supply regions. The higher estimated 2014 GHG emissions due to grid loss reflect that year’s higher electricity consumption levels and higher associated Scope 2 GHG emissions

Scope 3 GHG Emissions from Grid Loss (t CO2e)

2012 2013 2014
Canada 79,000 87,000 105,000
U.S. 105,000 102,000 138,000
Total 184,000 189,000 243,000

The above estimates are based on the following national- or regional-level grid loss percentage assumptions: For Canada, 6.67 percent, which we derived from Table A13-1 of Canada’s National Inventory Report (EC, 2015); for the U.S., 5.82 percent, which we derived from the eGRID U.S. – Eastern Region grid loss percentage, eGRID 9th edition Version 1.0, year 2010 summary tables (EPA, 2014). We have recalculated the estimates for each of the years based on these percentage grid loss values.

The GHG Emissions that Result from Employees’ Air Travel for Business - In the following table, we provide an estimate of the Scope 3 emissions that resulted from our employees’ air travel for business. We obtained this information from our corporate travel agency, and tracked it in our Emissions Data Management System. 

Employee Air Travel for Business (t CO2)

2012 2013 2014
Total 4,900 6,000 6,300

For more information, please see Employee Travel in this section of the report.

Our GHG Emissions Reduction Initiatives

In 2014 and 2015, we undertook the following GHG emission reduction initiatives:

Offices and Buildings – We reduced the Scope 1 and Scope 2 emissions that result from energy use in our offices and buildings through our efforts to build new facilities to LEED standards. Examples of such facilities are GD’s Technology and Operations Centre in the Toronto, Ontario, area and the new Enbridge Gas Storage administrative building in Mooretown, Ontario. We are also renovating GD’s Victoria Park offices in Toronto with LEED principles in mind and will be applying for LEED certification for the renovated spaces once they are complete. A number of our leased offices are also located in LEED Gold certified buildings, including three of LP’s leased offices, our corporate head office in Calgary, Alberta, and GPP&ES’s Houston, Texas, office, which is also an Energy Star Certified building. In Edmonton, Alberta, where we have approximately 2,500 employees, we are consolidating our offices from six buildings to two—the existing Manulife Place, which is LEED-EB Gold certified; and the new Kelly Ramsey Tower, for which the builders plan to attain LEED Gold Certification. Energy-saving features common to many other of our offices include energy-efficient lighting, motion sensors to control lighting, water-saving fixtures and recycling programs.

Vehicles – GD has the largest natural gas vehicle (NGV) fleet in Canada. Every RFP that it issues to vehicle manufacturers requires that the supplier provide vehicles that are either NGV ready or have a component for conversion to NGV.

So far, GD has converted 648 of its 853 fleet vehicles to run on natural gas. The majority of its vehicles are dual-fuel (they run on natural gas and gasoline). Some are medium-duty trucks, which are normally diesel-fueled. These have also been converted to run only on natural gas. Through this initiative alone, GD has reduced its GHG emissions by more than 500 t CO2e, compared to levels it would be emitting if it were operating gasoline or diesel-fueled vehicles.

GD has also reduced its fleet size by standardizing vehicle designs and building versatility into its fleet. For jobs that would have previously required three trucks, each with its own capabilities, GD has built three different job functions into one truck.

In addition, GD has installed a hybrid power system that enables work trucks to operate AC and DC power tools and equipment from their batteries when their engines are not running. This system not only reduces fuel consumption and GHG emissions, but vehicle idling, noise, and wear and tear.

Employee Travel - Although business travel has grown in recent years along with increases in our employee numbers, we have implemented initiatives that provide alternatives to travel. For example, by the end of 2015, we had 40 active TelePresence videoconferencing meeting rooms, and in 2015, our employees held 4,898 TelePresence meetings (1,803 of which involved three or more rooms).

We are also offering an increasing number of on-line training courses to employees. For example, Enbridge Gas Distribution (EGD, which is one of GD’s affiliate companies) now uses web-based training for many of its environment, health and safety programs, thereby avoiding approximately 14 t CO2e per year in employee travel-related GHG emissions. In the process, it has also reduced costs and improved productivity through reduced employee travel requirements.

GD also operates five natural gas vanpools in the Greater Toronto Area for its employees who commute to work at its Victoria Park offices. Each vanpool can hold eight passengers and a driver. In total, the program saves approximately 195 t CO2e annually. Employees benefit by reducing their vehicle fuel and maintenance costs, lowering stress, having preferred parking at the GD office, and having pride in knowing that they are doing their part for the environment and to relieve traffic congestion.

Stationary Combustion Equipment – Because our stationary combustion equipment—including the turbines and reciprocating engines that drive the compressors on GPP&ES’s gathering and transmission pipelines, as well as a variety of boilers, heaters and line heaters—uses a lot of natural gas, we operate it such that we maximize energy efficiency and minimize emissions.  We follow recommended maintenance and, in some cases, use asset management software to implement preventive maintenance programs involving air filter, oil and spark plug changes; hose, belt and rod packing inspections; and emission testing. We have also been able to reduce the energy requirements of our line heaters using new technologies and improved temperature control strategies.

Electric Pumps – Because the pumps that push crude oil through our pipelines use a lot of electricity, we aim to optimize their performance such that we lower both our costs and emissions. For example, we use additives or heat to reduce friction and improve the product flow. We also use various techniques to minimize pressure cycling, or the fluctuations in our pipelines’ operating pressures as we start and stop pumps and move crude oil products with different densities and viscosities. In 2014, we avoided emitting an estimated 59,900 t CO2e by using these techniques.

Construction - While the emissions associated with constructing our projects are small compared with the emissions associated with their ongoing operations, we have implemented several measures aimed at keeping them as low as possible.  For example, we use locally sourced pipe whenever possible. We also establish field offices and worker camps in the areas where we are building projects so as to reduce the travel time of project personnel. We transport workers to work sites via bus to reduce the number of vehicles on the roads, and we use local accommodations and trades services wherever possible.

Carbon and Sulfur Dioxide Reinjection - While processing natural gas, GPP&ES reinjects the carbon and sulfur dioxide that results from the process into two acid gas reservoirs near its Aker Treating Plant in East Texas. In 2014, GPP&ES reinjected more than 29,000 t CO2e and nearly 237 tonnes of sulfur dioxide that it otherwise would have emitted into the atmosphere.

Reduce Methane Emissions

Methane emissions and, to a lesser extent, carbon dioxide emissions, result from natural gas that has either leaked (through fugitive emissions) or been vented.  We are committed to reducing these emissions through the following efforts:

GD’s Efforts to Reduce Methane Emissions

GD finished removing all of the cast iron piping from its natural gas delivery system in 2012. By completing this process, we estimate that it was able to reduce its annual GHG emissions—chiefly methane—by approximately 145,000 t CO2e per year.

In addition:

  • GD has experienced a continued decline in the methane emissions caused by third-party damage to its pipelines, thanks to the implementation of Ontario One Call, a province-wide, one-call locate system that GD helped establish. For more information, please see the Emergency Preparedness & Response section of this report.
  • For several years, GD has installed excess flow shut-off valves on new service line installations, which reduce the amount of methane (and natural gas) released when service lines are damaged.
  • GD has replaced the majority of its high-bleed-rate pneumatic equipment. Begun in the early 1990s, this initiative has reduced methane emissions from pneumatic equipment by approximately 95 percent.
  • GD continues to manage its systems to reduce methane leaks through its extensive asset integrity program, which targets preventive maintenance on the equipment and piping with a higher risk of leaking.

GPP&ES’s Efforts to Reduce Methane Emissions

In an effort to reduce its methane emissions, GPP&ES:

  • has committed significant resources to its Leak Detection and Repair (LDAR) program. Employees at its processing plants now conduct monthly and quarterly LDAR monitoring for natural gas leaks. GPP&ES also uses a Best Management Practice that extends its monitoring to areas of the processing plants that are not subject to regulatory requirements.
  • uses forward looking infrared (FLIR) cameras in its LDAR monitoring. GPP&ES has successfully used the cameras at its plants, compressor stations and pipeline rights-of-way to identify leaks and emission sources and to enable timely repairs. The cameras’ ease of use and rapid-scan functionality enable GPP&ES to conduct leak detection surveys more often at facilities, resulting in the rapid detection of leaking components and lowered volumes of natural gas lost due to fugitive leaks.
  • maximizes the energy efficiency of its equipment—and thus reduces the possibility of methane emissions—using best management practices. Best management practices include conducting all recommended routine maintenance, monitoring the operations of individual engines, and ensuring optimal operating conditions.
  • conducts right-of-way surveillance and air patrols on its gathering and transmission pipelines.  The surveillance and patrols help GPP&ES quickly identify leaks.
  • regularly checks the fitness of its pipelines and other facilities to ensure that they are in good condition.
  • uses compressed air—rather than natural gas—to start the drivers in its large CAT® 3600-series compressors, thereby eliminating a source of vented emissions. GPP&ES’s preventive maintenance program for engines also helps ensure that its compression equipment is performing efficiently, and that combustion-related methane is kept to a minimum.
  • has replaced its high-bleed-rate pneumatic control devices, such as liquid-level controllers, pressure regulators and valve controllers, with no-bleed and low-bleed alternatives.

Reduce Energy Consumption

Our Direct Energy Use

The tables and graphs in this section provide information on the energy that we directly use within our operations, through our fuel consumption (of natural gas, propane, gasoline and diesel) and the energy that we indirectly use through our electricity use. Because fuel consumption and electricity use are significant operational costs for most of our business segments, we have a vested interest in optimizing our use of both direct and indirect energy.

Each of our business segments has a unique energy profile. Consequently, it would be difficult for us to establish one common energy intensity metric that we could apply across the company. We are, however, continuing our efforts to identify and quantify meaningful energy use metrics, and we plan to expand this section in future CSR and sustainability reports.

Enbridge’s 2014 Energy Consumption by Fuel Type

2014 Energy Comsumption by Fuel Type

Source category Gigajoules (GJ)
Fuel – stationary combustion 34,264,000
Electricity consumption 21,439,000
Total 56,463,000

Liquids Pipelines - The three-year energy consumption data for LP in Canada and the U.S. are provided below. By far, the largest component of LP’s energy use is electricity, which LP uses to operate the pumps that move liquid petroleum products through its pipelines. As LP has added new projects to meet producers’ needs for greater capacity and access to new markets, the electricity required to move the product has increased with the volume of product that LP delivers.

The increase in LP’s natural gas fuel consumption in 2014 over 2013 reflects its increased use of the natural gas in new office buildings, although the increase was offset by the lower amount of natural gas that LP used in its line heater at our Superior Terminal. The line heater heats the products that LP ships to reduce their viscosity, thereby reducing the pumps’ electricity requirements.

LP’s use of other fuels for its stationary combustion equipment is higher in 2014 due to LP’s use of new thermal oxidation units and to its use of diesel for temporary electricity generation at pump stations in Canada in 2013 and 2014.

LP estimates its energy consumption for mobile sources based on distances driven and, in the case of aircraft, hours flown. LP’s increasing use of energy for mobile sources reflects the fact that its fleet miles driven in 2014 were higher than in previous years. The increased fleet mileage in 2014 was due to a variety of factors, including the number of active projects, increased employee numbers, and expanded geographic areas of operation.

Liquids Pipelines 2012 2013 2014
(GJ) (GJ) (GJ)
Stationary Combustion Equipment – Natural Gas 107,000 284,000 289,000
Stationary Combustion Equipment – Other Fuels 52,000 128,000 323,000

Total – Direct Energy Consumption 15,120,000 16,003,000 20,708,000

The above data exclude the energy used by our smaller U.S. offices.

Gas Pipelines, Processing & Energy Services – Natural gas comprises the largest share of the energy that GPP&ES uses, largely because it fuels the natural gas-fired compressor drivers that GPP&ES uses to push product through its gathering lines and from offshore pipelines to GPP&ES processing and treating facilities. Other natural gas-fired equipment, such as boilers, amine units and various gas processing equipment, also contributes to GPP&ES’s natural gas use volumes. In addition, the Vector natural gas pipeline, which is part of GPP&ES, operates natural gas-fired turbines to run its compressors.

GPP&ES expects year-over-year variability in its natural gas consumption, as its usage depends on many factors, including the number of gas fields it services, the gas treating energy it requires to remove carbon dioxide or hydrogen sulfide from the gas, the volumes it delivers on the Vector pipeline and its offshore systems, and the extent to which it has expanded its system.

Electricity, which GPP&ES uses for lighting, controls, motors and other applications, comprises the next largest share of the energy that GPP&ES uses.

Gas Pipelines, Processing & Energy Services 2012 2013 2014
(GJ) (GJ) (GJ)
Stationary equipment – natural gas 40,646,000 37,547,000 32,698,000

Total direct energy consumption 42,637,000 39,425,000 34,534,000

Gas Distribution - Natural gas comprises the largest share of energy that GD uses for its natural gas distribution and underground storage operations. Natural gas fuels the reciprocating engines that drive the compressors that GD uses to inject and withdraw natural gas from underground storage facilities. It also fuels GD’s line heaters, space and water heating equipment, and the majority of its fleet vehicles. 

GD’s energy use varies from year to year, mostly because the amount of natural gas that it needs to inject and withdraw natural gas from its underground storage facilities varies. GD’s natural gas needs depend on winter temperatures, and the extent to which GD’s customers need natural gas from its storage facilities to meet peak winter demand.

Gas Distribution 2012 2013 2014

Electricity 65,000 73,000 68,000
Total direct energy consumption 732,000 940,000 1,155,000

Green Power, Transmission and Emerging Technology - GPT&ET requires relatively small amounts of energy to operate its wind, solar and geothermal projects. Its decreased natural gas use in 2013 from earlier years reflects its reduced operation of the natural gas-fired fuel cell that was located at GD’s Toronto, Ontario, headquarters.

Our Gas Distribution Customers’ Energy Use

We do not fully account for all of the energy that is used upstream and downstream of our operations.

In the interim, we provide information on the natural gas that our GD customers use. Although their usage is significant, through its DSM efforts, GD has successfully helped them reduce it. GD’s natural gas sales increased in 2014 partly because that year was colder than both 2012 and 2013. GD’s natural gas sales also increased in 2013 and 2014 because GD added approximately 35,000 new customers in both those years.

Our Efficiency Improvements and Conservation Efforts

We strive to reduce our energy consumption through efficiency improvements and conservation efforts. For example, we have reduced our energy use in our offices and buildings through our efforts to design and build new facilities to LEED standards. For more information, please see Our GHG Emissions Reduction Initiatives in this section of the report.

We have also introduced a variety of energy saving initiatives throughout our company, including the installation of energy-efficient lighting and motion sensors that turn off lights when inactive, and a range of recycling programs for paper, aluminum cans, toner cartridges, batteries, pens, permanent markers, highlighters and whiteboard markers.

And, we strive to build, operate and maintain our system operations to maximize energy efficiency.  For example, new heater technologies and improved temperature control strategies have enabled us to reduce the energy requirements of the line heaters in GD’s operations.

For more information, please see Our GHG Emissions Reduction Initiatives in this section of the report.

Disclosure on GHG Emissions and Energy Use

CDP, formerly the Carbon Disclosure Project, is an international, not-for-profit organization that provides companies and cities with a system to measure, disclose, manage and share vital environmental information. We disclose information to CDP on GHG emissions and energy use, as well as water use. For more information, please see the Environment & Land Management section of this report.

CDP scored and benchmarked our 2015 Climate Disclosure against companies within the energy sector globally. We received a Climate Performance Band score of “B,” which corresponds to a “Management” Disclosure Level score. CDP awards the Management score level to companies that provide evidence of actions associated with good carbon management and efforts taken to mitigate risks, including making their risk assessments more robust and comprehensive, implementing a carbon policy, and integrating carbon emissions reductions into their business strategies.

The CDP Climate Change Program average (for companies that qualified for a Performance Band) was C. We were among six other energy sector companies that scored B. A total of eighteen energy sector companies received a Performance Band score.

Help Customers use Energy Wisely

We are committed to helping our gas distribution customers use energy wisely. Through a wide range of DSM offers, GD encourages customers—from homeowners to industrial facilities—to adopt energy-savings equipment and operating practices to reduce their natural gas consumption.

Some of GD’s DSM activities in 2015 included:

  • energy-efficiency audits of residential homes, as well as of commercial and industrial facilities,
  • financial rebates and the sharing of technical expertise to encourage customers to adopt energy-saving equipment and practices,
  • home energy reports that help consumers better understand their energy usage and benchmark themselves against similar customers,
  • work with industry and trade associations in various sectors—such as schools, hotels and motels, construction, automotive, food and beverage, and pulp and paper—to promote DSM programs and enhance industry standards and best practices,
  • design charrettes (planning sessions) that support and educate builders on higher efficiency building options before construction begins, and
  • partnerships with governments, suppliers and equipment manufacturers on investments in new energy-efficient technologies that benefit ratepayers.

In 2015, GD submitted a comprehensive DSM plan to the Ontario Energy Board that would introduce a broad suite of new and enhanced offers. Its multi-year DSM plan, which runs from 2015 to 2020, commits approximately $360 million to target well over six million cumulative cubic meters of natural gas savings, reducing customers’ emissions by roughly 12 tCO2e over the lifetime of the plan. The DSM plan represents a major step toward increased energy efficiency and reduced customer emissions in Ontario.

Cumulatively, between 1995 and the end of 2014, our DSM programs saved approximately 9.6 billion cubic meters of natural gas and reduced carbon dioxide equivalent emissions by 18 million tonnes¹. These reductions are similar to those that would be achieved by taking approximately 3.5 million cars off the road² for a year or by meeting the natural gas needs of approximately four million homes³ for a year. These reductions have created net benefits to society worth approximately $2.5 billion. For a utility that delivers just over 11 billion cubic meters of natural gas to its customers in an average year, the savings achieved to date are significant, and do not even include the gas savings that will be achieved for decades into the future as a result of past efforts.

¹ Figures are subject to Clearance of Accounts proceeding before the Ontario Energy Board. We have assumed that 1.89 kg of CO2e are emitted for each m3 of natural gas that is consumed.

² We have assumed that the average automobile produces 5.1 tonnes of carbon dioxide per year.

³ We have assumed that a typical residential customer uses 2,400 m3 per year of natural gas to heat his or her home and water.

Because GD is viewed as a recognized leader with regard to its success with DSM initiatives, over the past number of years it has been invited to provide advice on DSM policy and programming throughout Canada and the U.S.
