Clean Electricity Regulations: Formula Correction

Summary#

This is an erratum to the Clean Electricity Regulations (SOR/2025-263). It corrects a small mistake in a calculation formula that was published on December 18, 2024, and the correction was published on February 26, 2025; the online (HTML) version has already been fixed.

What it does#

• Under subsection 16(1), a term in a summation formula was changed. The erroneous term using the subscript "h" was replaced with the correct subscript "w".
• Concretely, the numeric factor 0.01 remains the same, but the formula component changed from the previous form to use the correct variables.
• The notice says the HTML version of the Clean Electricity Regulations has already been updated to reflect the fix.

Who's affected#

• People and groups who use the regulations' formulas for calculations, such as compliance officers, consultants, lawyers, and electricity producers, are the most likely to notice the change.
• Regulators and anyone relying on subsection 16(1) calculations for reporting or enforcement could also be affected.
• If it is unclear whether your specific situation is affected, this notice is technical and you may need to check the corrected formula or seek technical advice.

Why it matters#

• The change fixes a typo in a calculation. That can change a numerical result if someone previously used the wrong variable, so it matters for accurate reporting and compliance numbers.
• Because the correction is narrowly focused on a formula term, it appears to be a technical fix rather than a policy change. The erratum does not state broader changes to obligations under the Canadian Environmental Protection Act, 1999.
