Local Distribution Company (LDC) Form B
LDC Individual Generation Assessment Application
Hydro One Distributed Generation Group | DxGenerationConnections@HydroOne.com | 1-877-447-4412 (Option 2)
General Application Information
Applicants
This Application form is to be used only by a Distributor (“LDC”) to apply to Hydro One for a Connection Impact
Assessment (“CIA”) or Detailed Technical Connection Assessment (“DTCA”) on behalf of a generation proponent
connecting to the LDC’s Distribution System. This application is to be accompanied with the LDC’s generation
connection application as completed by the generation proponent, which must provide the minimum information
requirements listed in Appendix A and, if applicable, Appendices B, C and D of this application form.
Technical Requirements
For technical requirements of Hydro One’s FIT projects, refer to the “Distributed Generation Technical
Interconnection Requirements Interconnections at Voltages 50kV and Below” available at:
http://www.hydroone.com/Generators/Pages/TechnicalRequirements.aspx.
Application Submission Instructions
Please return the completed form, fees and other required documents by mail to:
Hydro One Networks Inc.
Attn: Dx Generation Connections
Generation Connection Application
185 Clegg Road
Markham, Ontario L6G 1B7
Important Notes

Applicants are cautioned NOT to incur major expenses until Hydro One approves to connect the proposed
generation facility.

All technical submissions (Form B, Single Line Diagrams, etc.) must be signed and sealed by a licensed Ontario
Professional Engineer (P.Eng.).

All fields below are mandatory, except where noted. Incomplete applications may be returned by Hydro One
Networks Inc. (“Hydro One”). Failure to provide the minimum information requirements will result in delays in
processing your application.

If you are applying for connection of a Load Displacement or Energy Storage facility, the assessment performed
by Hydro One is a Detailed Technical Connection Assessment (“DTCA”). For such facilities, the term
Connection Impact Assessment (“CIA”) as it appears throughout this Form B shall be interpreted to mean
Detailed Technical Connection Assessment (“DTCA”).
If you have any questions please e-mail Hydro One’s Business Customer Centre at
dxgenerationconnections@hydroone.com or call 1-877-447-4412 (Option# 2) 8 : 3 0 am to 5:00 pm Mon to Fri).
