The ACC held a virtual Open Meeting on Tuesday and is working with a light agenda. There was only on electric item. Here's the summary from the meeting highlights.
April Open Meeting Highlights
Commissioners Approve Tucson Electric Power Company Transmission Line to Enhance Davis Monthan Air Force Base Energy Resiliency
Commissioners approved an application for a Certificate of Environmental Compatibility authorizing the Irvington to East Loop 138 kilovolt (kV) Transmission Line Project, which includes the construction of new 138 kV transmission lines originating at the Irvington Substation (Section 03, Township 15 South, Range 14 East), with an interconnection at the Port Substation (Section 18, Township 15 South, Range 15 East) and terminating at the East Loop Substation (Section 08, Township 14 South, Range 15 East), each located within Pima County, Arizona.
The project’s structure will be in Tucson and Pima County and entails the construction of 12.78 miles of new 138 kV transmission line that will be constructed on a mixture of weathering tubular steel tangent and dead-end monopoles. The project will enhance TEP's ability to respond to future load growth, provide contingency support to existing distribution substations, assist Davis-Monthan Air Force Base ("DMAFB") in fulfilling the Department of Defense ("DOD") directive for enhancing energy resiliency, and over time allow replacement of part of the existing project description and alignment aging 46 kV system serving the area. The existing electrical infrastructure does not provide enough capacity to serve future load growth and needs to be enhanced to provide DMAFB the resiliency it needs in order to fulfill the DOD directive.
