Title: Hydro One Networks Inc. (EB-2026-0193) - Electricity distribution rate order exemption related to gross load billing

Case number: EB-2026-0193

Type:

Filed: July 24, 2026

Hydro One Networks Inc. (Hydro One Networks) has applied to the Ontario Energy Board (OEB) for an exemption from provisions in its distribution Rate Order for an existing customer who is connected to its distribution system, and a prospective customer who has requested a connection to its distribution system, both located in the Leamington area. Hydro One Networks has applied for the following approvals:

• An exemption from provisions in its Rate Order (EB-2025-0030) pertaining to the application of Gross Load Billing (GLB) for distribution customers with embedded generation facilities
• An amendment to its Rate Order to allow Hydro One Networks to apply a proposed alternative approach to GLB to any other identical scenarios that may arise

A Rate Order is the OEB decision that sets the rates a utility can charge customers and explains when and how those rates will take effect. GLB is a mechanism that Hydro One Networks uses to recover the cost of providing a customer's maximum potential demand, combining both the power drawn from the grid and the power supplied by customer’s own generation, for the grid capacity built to support the customer’s peak demand. 

Hydro One Networks submits that no person will be adversely affected in a material way by the outcome of the proceeding and has requested that the application be decided without a hearing. If you believe a hearing is needed, then you can request one by filing a letter with the OEB no later than July 31, 2026. You should indicate whether you have a preference for the hearing to be oral, electronic or written. If you do not file a letter by the due date, you will not receive any further notice in the event the OEB proceeds with a hearing. If you submit a letter, your name and the content of your letter will be put on the public record and the OEB website.

Title: Hydro One Networks Inc. (EB-2024-0142) - Port Colborne Expropriation

Case number: EB-2024-0142

Type:

Filed: April 11, 2025

Hydro One Networks Inc. (Hydro One) is asking the Ontario Energy Board (OEB) for permission to expropriate interests in certain lands near the City of Port Colborne. Hydro One says that the expropriation is needed so that it may continue to operate and maintain existing transmission lines that are located on the lands. The existing transmission lines were originally constructed in the 1960s and form part of the Independent Electricity System Operator controlled transmission grid.

Hydro One’s application is about the expropriation of certain lands only. It is not about compensation. The OEB will consider the public interest when making any order authorizing Hydro One to expropriate land. The OEB does not have the authority to determine the amount of compensation payable. If the OEB authorizes Hydro One to expropriate and the parties do not agree upon compensation, then the compensation must be determined under the Expropriations Act by the Ontario Land Tribunal.
