CAM Eligibility and Demand Estimates

The CAM is designed for large-scale, primarily residential developments requiring significant infrastructure investment. To qualify, a project must meet all five of the following criteria:

Involves a large, primarily residential area (may include schools, plazas, parks, or ground-floor commercial spaces serving residents, with the majority of load from residential customers). It must be a new development without a finalized agreement or expansion plan.
Expects multiple developers to connect over multiple years (up to maximum15 years), based on municipal official and secondary plans.
Has mature development plans, with at least a site plan in progress, providing details on roads, civil infrastructure, and electrical requirements.
Requires significant system expansion, such as new or expanded transformer/distribution stations or long distribution feeders.
Includes a significant portion of committed capacity security (e.g., cheque, letter of credit).

If your project aligns with these criteria, contact London Hydro for a preliminary assessment. The CAM is not applicable to small-scale or non-residential-focused projects.

To support consistent forecasting for customer’s requested capacity, London Hydro provides the typical demand values for different residential building types:

Typical Home Types	Basic Expected Demand	Each additional EV connection	Each additional Heat Pump connection
Stacked townhouse, condo unit, row townhouse	3 kW	9kW*	1kW
Row townhouse with parking garage, detached single family, detached townhouse	5 kW	9kW	3kW
Estate lots	15 kW	9kW	5kW

* This is accounting for one public charger in parking lots or common parking area.

These estimates help calculate your project’s share of infrastructure costs. Contact our team for tailored guidance.
