Remove Power Consulting Service

The filing notes no customers have subscribed to or used this service since at least about September 2025 and the Exchange does not expect any effect on participants.
Update Electrical Terminology to 110/120V
The Exchange is updating technical terminology in Rule General 8, Section 1(c) (Power) by changing references from “110 volt” to the industry-standard “110/120 volt.” This is a non-substantive wording change intended to align with prevailing electrical specifications.
