Limitations and Disclaimer
Informational Purpose & No Guarantee of Accuracy: The Capacity Map is for informational purposes only. Customers should not make decisions based solely on the Capacity Map. It is provided to identify areas where interconnections could be added, which may require fewer significant modifications to the distribution system. It does not guarantee available capacity on the distribution system. The information displayed is approximate, subject to change, and provided on an "as is" basis without promises regarding accuracy, completeness, or timeliness. Users must verify the information with London Hydro and seek professional guidance before making any decisions based on the Capacity Map. A formal study is required to determine actual available capacity, interconnection feasibility, cost, and timelines, all at the customer’s expense.
External Considerations & Permitting: Interconnection feasibility is subject to regulatory requirements, permitting approvals, and third-party considerations. Customers must comply with all applicable regulations and approvals. Interconnection availability may be affected by external factors such as existing infrastructure constraints and zoning laws.
