There are six phases in the transmission generation connection process that include multiple steps and procedures within each phase that may overlap to facilitate critical in-service dates.

Getting Started

You should first complete a pre-consultation with Hydro One and read these important considerations before you begin the transmission connection process for Generators.  

Process Overview

The phases of the transmission connection process are identified below. Click on each phase for more detail:

Phase 1 - Connection Application
Phase 2 - System & Customer Impact Assessments
Phase 3 - Connection Estimates
Phase 4 - Cost Recovery Agreement
Phase 5 - Design and Build
Phase 6 - Commissioning

  IESO Connection Assessment & Approval (CAA): Customers requesting a new or modified
  connection to Hydro One's transmission system must apply and register with Hydro One and The
  Independent Electricity System Operator (IESO).
The IESO
Connection Assessment and Approval
  (CAA) is a separate process that runs parallel with Hydro One's Customer Connection Process.
  The CAA process includes a System Impact Assessment (SIA) which is conducted to assess the
  impact of the connection proposal on the reliability of Ontario's transmission system.
