**What changed:** A September 2026 application to the Wyoming Public Service Commission (docket 20003-278-EN-26, Record 18235) covers a proposed South Cheyenne 230 kV substation and 115/230 kV lines.

**Why it matters:** New load in Cheyenne depends on delivery capacity as well as generation. This is an application, not an approval, and it does not establish available transfer capability or an energization date.
