Distribution System Capacity Information Map

There are limits to connecting to the distribution system. Learn more below.

Our electricity distribution system has technical limits to the amount of electricity distribution that can be connected at any point on the network. When these limits are reached, the system is considered to have reached its capacity. The capacity for various sections of the distribution system varies depending on the equipment installed along the path from the generator to the customer.

To help commercial customers make preliminary decisions regarding their projects, we publish information regarding the estimated capacity available on our distribution system.

Our Capacity Information Map displays the remaining electrical distribution capacity at the station and feeder levels for potential commercial DER and EV charging station connections.

In order to attach a new electrical connection, Burlington Hydro must ensure there is sufficient electrical capacity available. Before starting your project, please complete this general service request form to initiate a discussion about your specific connection needs and next steps.

Capacity Allocation Model (CAM)

The Ontario Energy Board (OEB) has established a Capacity Allocation Model (CAM) to support a fair allocation of capacity and costs associated with system expansions to accommodate multiple residential subdivisions and other customer connections in a qualifying development area.

System expansions that are subject to a CAM are constructed to provide significant distribution capacity to a qualifying development area, for example, construction of a distribution transformer station or long distribution feeders. Calculations completed under a CAM do not include forecasted revenues.

The CAM is NOT applicable to any system expansion to only accommodate a single customer connection that will be completed in a single year.

The CAM is effective as of September 16, 2025. Please refer to Appendix I – Methodology for Implementing a Capacity Allocation Model of the Distribution System Code (DSC) for more information.

General Information

A Capacity Allocation Model (CAM) may be used for a large, multi-year expansion in a defined development area with more than one residential development to bring in significant capacity that cannot be met by the existing infrastructure. The purpose of this model is to ensure a fair allocation of capacity and costs associated with system expansions amongst the connecting developers and rate payers.

Each developer who requests capacity under a CAM is subject to a capital contribution based on their proportion of the constructed capacity, per the prescribed methodology in Appendix I of the DSC.

Developers who choose not to make a full capital contribution payment in year one of the CAM term will be required to pay a financing charge in addition to the capital contribution. BHI will require payment or binding financial commitments for any agreed committed capacity.

Typical Demand Values

Below are typical demand estimates (kW) – used to calculate capacity needs consistently under the CAM for homes/residential units on average:

• Low - 3kW
• Medium – 6kW 
• High – 10 kW
