ACC vote regarding UNSE Black Mountain Generating Station expansion project
PHOENIX – The Arizona Corporation Commission voted 4 – 1, with Commissioner Anna Tovar dissenting, to reverse the Arizona Power Plant and Transmission Line Siting Committee’s Order regarding an expansion project at the Black Mountain Generating Station operated by UNS Electric, Inc. The Request by UNS Electric, Inc. for a Disclaimer of Commission and Committee Jurisdiction has been granted pursuant to A.R.S. 40-360, and this Decision is effective immediately. The decision means that the Commission does not have mandatory jurisdiction over electric generating plants under 100 MW for line siting purposes, a result dictated by law.
