status natural gas basics
Status: Natural Gas Basics
  • Natural gas is the cleanest burning conventional fuel:
    • 45% less CO2 than coal
    • 30% less CO2 than oil
  • Domestically available:
    • 98% of natural gas consumed in Canada & US is produced in North America
  • Efficient:
    • 90% of natural gas’ energy value is delivered to customers
    • Customers today use 40% less natural gas than 40 years ago
  • Abundant:
    • Over 100 years of proven supply
status natural gas in ontario
Status: Natural Gas in Ontario
  • 3.2 million residential, commercial and industrial customers serviced by Enbridge Gas Distribution and Union Gas Ltd.
  • In the residential market:
    • 95+% of customers use it for heating
    • 85+% use it for domestic water heating
    • 20-25%% use it for cooking
    • 20-25% use it for clothes drying
opportunities energy efficiency
Opportunities: Energy Efficiency
  • Since 1997, through DSM programs, Union Gas has helped customers:
    • save 820 million cubic meters of natural gas
    • 1.6 million tones of CO2 emissions – the equivalent of taking more than 295,000 cars off North American roads
  • Moving from a “programmatic” view of energy efficiency to a “market transformation” view, ie:
    • high efficiency furnaces
    • Energy Star for new homes
  • Importance of full fuel cycle cost analysis
    • right fuel for the right application

  • 1,100 MW (DD) to 6,400 MW (CD) saved
  • 6 million tonnes of GHG emission reduced (gross)
  • Average cost per MW saved:
    • $58,000 (CD) to $335,000 (DD)
    • 10% (CD) to 60% (DD) of gas fired generation per MW
    • 3% (CD) to 20% (DD) of renewable generation per MW

going forward integrated energy systems
Going Forward: Integrated Energy Systems
  • The majority of natural gas power generation in Ontario is still confined to large scale centralized systems
  • Decentralized and integrated energy systems is the next path to lead
  • Fundamental to this thinking is to move from the current discussions of “smart grid” to a wider view of constructing a “smart energy network”:
    • CHP and Micro-CHP
    • Micro-grids
    • District Energy Systems
    • On-site integration of natural gas and renewables: passive solar
quality urban energy systems of tomorrow
Quality Urban Energy Systems of Tomorrow
  • The Canadian Gas Association was instrumental in founding QUEST five years ago
  • The mission is to have every community in Canada operating as an integrated energy system:
    • Improve Efficiency
    • Optimize Exergy
    • Manage Heat
    • Manage Waste
    • Use Renewable Sources
    • Use Grids Strategically
opportunities biomethane
Opportunities: Biomethane
  • Biogas from anaerobic digestion and gas from landfill sites can be upgraded to biomethane and injected into the natural gas system
  • Enbridge & Union are working jointly to establish a Biomethane Reference Gas Price:
    • Enable the biomethane market by establishing appropriate pricing and supply contracts
  • Looking to the future new “gasification” technologies can further transform the market by allowing biomass to be moved via pipeline
natural gas future in ontario
Natural Gas future in Ontario

Over the last decade, natural gas has often been referred to as a “bridge fuel”—going forward it is a “foundation fuel”

The transformation of Ontario to a lower carbon future requires the flexibility of natural gas

The significant infrastructure of the natural gas transmission and delivery system in Ontario needs to be leveraged through integration with community energy systems

As “green gas” sources are developed (biogas and gasification of biomass), the existing infrastructure can help in directly delivering a lower carbon future
