Three Rivers 230kV
Voltage - 230kV
Estimated completion date - 4th Quarter 2021
Location - East Goodyear and west Avondale area
Connect new power lines and substation into an existing 230kV transmission line to serve a new data center located west of Bullard Avenue between Van Buren Street and Yuma Road.
The greater Phoenix region has emerged as one of the top markets in the western United States for attracting high-tech industries, including data center companies. The west valley, in particular, is benefiting from economic development activity that will bring jobs and revenue to the area. We are dedicated to providing safe and reliable electric service to support this growth. In February 2020, we announced the need for new electrical infrastructure to serve a new data center in Goodyear, and support the overall growth in the west valley. We held public open house meetings on February 19 and 20, in Avondale and Goodyear to explain the purpose and need for this project, answer questions, discuss potential routes for the power lines, and solicit input from all who attended. The feedback you provided at the open house and through mail, email, telephone and the project webpage helped us identify several route alternatives. In July 2020, we launched a virtual open house to share the results of these studies and present these route alternatives to once again gather public input, answer questions, and solicit feedback to determine optimal route options for the new transmission lines. These lines are needed to connect the new Three Rivers Substation, located near Bullard Avenue and Van Buren Street in Goodyear, to the existing power line along the Agua Fria River in Avondale.
The studies we have conducted include environmental impacts, engineering and construction feasibility, land acquisition timing and costs, potential impacts to existing and planned neighborhoods and businesses and input from agencies and the public. Results of these studies have helped us identify three route options: a Preferred Route, Alternative Route #1, and Alternative Route #2 (see Three Rivers 230kV Project Map link below). Each route option forms a looped connection from the existing 230kV transmission line along the Agua Fria River in Avondale to the Three Rivers Substation located near Bullard Avenue and Van Buren Street in Goodyear, then back to the existing 230kV transmission line.
Three Rivers 230kV Project Map
Monopole (single pole) structures are typically used for new 230kV transmission lines, but may include a variety of steel structure types, ranging in height from approximately 115 feet tall to a maximum height of 195 feet depending on routing, terrain and crossing of existing structures, including elevated roads and other power lines. The typical rights-of-way or easements are approximately 120 feet wide (60 feet each side of the structure), but may also vary. Any opportunity to utilize existing 69kV power line routes for the new 230kV structures will be considered.
