IMPORTANT NOTES:
 If this project requires line expansion work between the POC and PCC, Hydro One will provide a cost estimate to construct
 any line located on public road right-of-way. The cost estimate will include a breakdown of Uncontestable work (i.e.
 overbuild to existing line) that can only be performed by Hydro One, as well as Contestable work (i.e. new
 construction/green-field) that can be performed by the Generator, their contractor or Hydro One. (Both Uncontestable work
 and Contestable work requires the design to Hydro One specifications). Hydro One will become the owner of the line
expansion.
 For Generator-owned line, the Generator may choose to apply for installation of the line on existing Hydro One-owned poles.
 This is known as an application for Joint Use (JU) of poles. If the application is accepted, Hydro One will provide the
Generator with information on initial connection costs, annual pole-space rental and emergency service (ES) fees, and
required JU & ES Agreements.
