Distribution Generator Interconnections
The distribution generator interconnection team assists generator owners who would like to connect to the BC Hydro distribution system (up to 35kV). We will be able to help you if you are:
- An independent power producer (IPP) who intends to sell power to BC Hydro;
- A customer using one or more generators to offset your load consumption (also called load displacement);
- An existing customer adding or replacing a generator to your facility; or
- A generator owner who would like to synchronize your generator to our network.
For interconnections over 35kV and information on our wholesale transmission service, see transmission generator interconnections.
Connection process overview
Requests for interconnection are done on a first-come, first-served basis. Each interconnection request is reviewed for technical compatibility to ensure the proposed generator is able to be connected. We'll also assess the impact of the proposed generator on our system and facilities.
The general interconnection process for generator owners or independent power producers is outlined in the following five steps. Please note that there may be slight variations in the process for specific BC Hydro competitive electricity acquisition activities.
- Basic distribution system information request
- Screening study (recommended but optional)

Distribution micro-generator projects
We define a distribution generator micro-project as one that intends to add over 100 kW and up to 1 MW into the distribution system. Once you have successfully completed the basic distribution information request and screening study for your proposed micro-project, you may submit a completed distribution micro-generator project design stage application form along with a $7500 deposit.
Temporary transfer of load, closed transition transfer
If you have a generator you're looking to connect to our grid for the purpose of temporarily transferring load to/from standby generation to/from BC Hydro, or closed transition transfer, please see the following information.
