**What changed:** Cheyenne Light’s application for the 230 kV Holliday Substation was on the Wyoming Public Service Commission’s July 30, 2026 agenda, and the docket lists an open-meeting action on that date. We haven’t found minutes showing the outcome, and no order is posted, so we aren’t calling it approved.

**Why it matters:** The application estimates about $11.93 million: $6.40 million for the substation, $4.25 million for network upgrades and $1.28 million for a generator tie line of about 1.7 miles. The company’s targets are easements, environmental permits and a construction start in Q3 2026\. The application targets service in Q2 2027\. The July staff memo repeats that date in its prose but lists Q3 2027 in its timetable; the discrepancy remains unresolved. The memo names the generator as Enbridge Solar (Cowboy Solar II) LLC, formerly TGE Wyoming 225 LLC, and says its energy will be assigned to GOAT Systems LLC, a large-power customer.

**Next step: monitor.** Watch for the July 30 minutes, an order or construction reports. The staff memo asks for monthly reports in future filings.
