Electricity Transmission Rates for Chatham-Lakeshore Line (2026-2029)

Official title: 2026-2029 electricity transmission revenue requirement

Closed Regulations & Permits Finance & Consumer Natural Resources
Chatham x Lakeshore Limited Partnership wants to update its electricity transmission rates for 2026-2029. The Ontario Energy Board has already issued a decision on this case in December 2025. This affects how much the company can charge for moving power through its transmission infrastructure in southwestern Ontario.

Why This Matters

Live in southwestern Ontario? Your electricity bill includes transmission costs. When transmission companies get rate increases, those costs eventually show up on your bill. This particular case is technical and already decided, but it's part of how electricity pricing works in Ontario.

What Could Change

The OEB has issued its decision. The approved rates will determine how much Chatham x Lakeshore can charge for transmission services from 2026 to 2029. These costs flow through to local distribution companies and ultimately to ratepayers in the region.

Key Issues

  • What transmission rates should Chatham x Lakeshore be allowed to charge for 2026-2029?
  • Are the company's cost of capital and debt rate calculations appropriate?

What Happened

The Ontario Energy Board issued a Decision and Order on December 16, 2025, concluding this rate proceeding. The case went through a written process including interrogatories from OEB staff and reply submissions from the applicant.
