Westwood Substation Construction Begins in Ririe

January 26, 2017


IDAHO FALLS, Idaho — Construction of Rocky Mountain Power’s new Westwood substation and associated power line upgrades have begun in Ririe, Idaho. All aspects of the project are expected to be completed by sometime in June.

The Westwood substation will be built on the northeast corner of the intersection at 65 East and County Line Road (145 North). The power line work will take place along the eastern portion of County Line Road then south along 115 East to 101 North and will connect with another line being constructed east and south along 101 North.

“All this work will help the company meet the electrical needs of new customers and the growing needs of existing customers in the area,” said Tim Solomon, Rocky Mountain Power regional business manager. “In total, about 12 miles of new power line will be constructed and the new substation will enable us to remove the current Ririe substation.”

It is expected the line construction will be completed sometime in March or April, depending on weather. The substation construction should wrap up in May followed by testing and connecting it to the system by mid-June. Throughout the project schedule, heavy equipment, contractors and utility personnel will be working in the area. Large transformers and other substation equipment will be shipped in on heavy transport vehicles and offloaded with cranes.

“We want everyone in the area to be aware of this activity and to exercise caution as work progresses,” Solomon said. “Flaggers will be in the area to help the traveling public throughout the work zones. We hope everyone will be attentive, observe construction signs and follow flagger instructions.”
