Distributed Generation

Why Distributed Generation?

Benefits for you:

  • Resilience: Grid-connected distributed generation(DG) can provide you with continuous backup power for essential loads if the main grid goes off-line. The more DG, the more loads can be covered.
  • Cost: Distributed generation can drastically reduce your electricity bill through using free or lower-cost energy sources. In Ontario, electrical energy cost has been rising by some 9% per year, much of this due to Global Adjustment. In addition, DG can also reduce Demand Charges and Carbon Charges.
  • Efficiency: With biogas, landfill gas and natural gas generation, typically twice as much heat energy is produced in addition to electricity. Combined heat and power (CHPsystems generate electricity and useful thermal energy in a single, integrated system.

Benefits for the grid:

  • Losses: Local distributed generation reduces grid losses through reducing power transfers
  • Resilience: With higher power transfers, the risk of a cascading grid failure in increased.
  • Reduced vulnerability: Many small DG are much less vulnerable to extreme event or cyber-attacks that could disrupt supply

Benefits for the environment:

  • Carbon-free: Wind, solar & hydro electricity generation is carbon-free which helps fight global warming
  • Biogas: kills pathogens which in turn creates a usable byproduct, reduces odours and converts methane to carbon dioxide. Methane is a greenhouse gas, 21 times worse than carbon dioxide.
  • Efficiency: CHP is highly efficient as heat energy is not wasted
  • Transport: Removes the need to transport fuel long distances to remote communities

What is distributed generation?
Distributed generation(DG) refers to a variety of technologies that generate electricity at or near where it will be used.
Some more effective DG technologies include:
