Fuel Options

LNG Diesel Dual-Fuel
Environmental Considerations
  • Lower emissions (GHG, particulate matter, NOx)
  • Harder to use with integration of future intermittent renewables
  • Lower environmental effects of spills
  • Higher emissions (GHG, particulate matter, NOx)
  • Better suited to future integration of intermittent renewables
  • Higher environmental effects of spills to land and water
  • Medium emissions (GHG, particulate matter, NOx)
  • Harder to use for future integration of intermittent renewables
  • Higher impacts of spills to land and water (diesel)
Social Considerations None None None
Economic Considerations
  • Potential for project investment by First Nations as an alternative energy project
  • Does not require new infrastructure to store LNG; can use existing storage
Operational Considerations
  • Higher safety requirements
  • More complex to operate
  • More complex logistics and operations required for fuel transportation, storage and handling
  • Responds slowly to changes in load
  • Less complex to operate
  • Responds quickly to changes in load
  • Flexibility to run on both LNG and diesel reduces fuel price and availability risk
  • Start-up characteristics of diesel; running characteristics of natural gas
Technical Considerations LNG Diesel Dual-Fuel

Owned vs. Rented Generators

Owned Generators Rented Generators
  • Higher reliability
  • Available year round
  • Higher cost certainty
  • Higher construction cost; lower operating costs
  • Lower reliability
  • Only available during winter months
  • Future availability of rental units uncertain
  • Uncertain future rental costs; costs may increase over the life of the plant
  • Lower construction cost; higher operating cost
