Types of non-utility generation

Standby generation

This generation creates electricity as a back-up for your own use. There are 2 types of standby generation:

Open transition switching

  • typically associated with Uninterrupted Power Supply (UPS) backup generators and is connected to the internal home or business wiring system;
  • a manual switch on the generator will break the connection with Manitoba Hydro before electricity is received from your generator;
  • Canadian Standards Association approved transfer switch is required;
  • generator must be inspected by a one of our electrical inspectors.

Momentary closed transition switching

A type 1 generator is interconnected to our grid with momentary closed transition switching. The power between the generator and our grid briefly runs simultaneously for 100 milliseconds or less. A connection with your generator is made before contact is broken with us. This is so that there is no interruption to the load (power) during this transfer. This is usually to avoid nuisance outages associated with monthly testing of UPS backup generators.

Parallel generation

These 2 systems types are known as parallel generation because they generate power on your side of the meter and are interconnected to our grid. Power from both sources are working at the same time.

Load displacement only

These systems can parallel indefinitely and are primarily used for load displacement. Your generator meets some of your energy needs which will reduce your energy bill, while still relying on us for the remainder of your electricity.

Load displacement plus excess to grid

The generator is interconnected using Sustained Closed Transition Switching. These systems can parallel indefinitely. In this case, the excess energy that you generate is allowed to flow into the grid. Power flow is limited by the size of the existing supply transformer and the breaker rating.

Independent power producer

This type of generation produces electricity for the only purpose of selling it to us and can be very costly.
