News updatesHere you'll find updates for both the PV-PW and PW-SEV/BRG (formerly PW-SEV/BOB) projects, including a timeline of events for each project. ACC approves SRP's request for 230kV/500kV consolidationOn Dec. 8, 2006, the Arizona Corporation Commission issued an Order (Decision No. 69183) approving SRP's request to construct a 230kV circuit on the 500kV structures to be built along the Pinal West to Southeast Valley certificated route in Casa Grande. Specifically, SRP will add a 230kV circuit to the 500kV structures at a point on Cornman Road near the intersection with Thornton Road and continue east along the route to the future Pinal South Substation. The request was made in compliance with Condition 23 of the Pinal West to Southeast Valley CEC (Decision No. 68093). The 230kV circuit will be part of the planned Desert Basin 230kV Power Line Project. SRP intends to file a CEC application for the portion of the Desert Basin 230kV Power Line Project exiting the Desert Basin Generating Station and continuing south for approximately six miles to intersect with the 500kV corridor. Pursuant to the ACC Order, construction of the 230kV circuit on the 500kV structures may not occur until SRP receives a CEC for the remainder of the project.

SRP submits compliance filing for PW-SEV/BRG 500kV project conditionOn Aug. 11, 2006, SRP filed a request with the Arizona Corporation Commission (ACC) to construct a 230kV circuit on the 500KV structures along the certificated route south of Casa Grande. Specifically, SRP is requesting that a 230kV circuit be added to the 500kV structures at a point on Cornman Road, near the intersection with Thornton Road, and continue east along the route to the future Pinal South Substation. The 230kV circuit will be part of the planned Desert Basin 230kV project. This filing satisfies the requirements of Condition No. 23 of the Certificate of Environmental Compatibility (CEC), Decision No. 68093, for the Pinal West to Southeast Valley/Browning Transmission project. Once the ACC approves SRP's request for the double circuit structures, SRP will move forward with obtaining the appropriate line siting approvals for the proposed Desert Basin 230kV project.

SRP provided a public notice of this request to landowners located within the allowed corridor along the certificated route from the intersection of Burris and Cornman Roads to the future Pinal South Substation. View the public notice and ACC's approved route map.
Arizona Corporation Commission grants CEC for PW-SEV/BRG 500kV projectOn Aug. 16, 2005, the Arizona Corporation Commission (ACC) voted unanimously (5-0) to confirm a Certificate of Environmental Compatibility (CEC) for the Pinal West-to-Southeast Valley/Browning (PW-SEV/BRG) project. The ACC held a special open meeting Nov. 9, 2005 at which the Commission voted unanimously on the Pulte request for reconsideration of the CEC decision. The amended decision extends the 500kV transmission line corridor width to a half mile on the east side of the centerline of the Valley Farms/Cooper Road section line, but for only the area that is north of the state land to the Union Pacific Railroad. Pulte's original request was to expand the corridor width to include the state land as well as the land located south of the state land to the north side of the Gila River.

Siting committee recommends CEC for PW-SEV/BRG projectThe Arizona Power Plant and Transmission Line Siting Committee recommended that Salt River Project be granted a Certificate of Environmental Compatibility (CEC) for its Pinal West-to-Southeast Valley/Browning (PW-SEV/BRG) project. The siting committee reached their decision at the May 10, 2005 hearing, following a full day of discussion and debate. Committee chairman Laurie Woodall signed the CEC on June 8, 2005 and forwarded the siting committee's recommendation to the ACC for its consideration.

Arizona Corporation Commission approves PV-PW projectMay 18, 2004 - The Arizona Corporation Commission (ACC) approved the certificate of environmental compatibility (CEC), Decision 67012, for the Palo Verde to Pinal West (PV-PW) Project on May 18, 2004. The PV-PW Project consists of two new 500-kilovolt transmission lines that will serve Pinal, Pima and Maricopa counties. SRP will begin building the facilities in 2005, with an expected in-service date of 2006. Partners in the PV-PW Project include SRP (project manager), Tucson Electric Power Co., Southwest Transmission Cooperative Inc., Electrical District Number 2, Electrical District Number 3, and Electrical District Number 4. PV-PW project backgroundSRP submitted an application for a CEC with the ACC for the Palo Verde-to-Pinal West (PV-PW) project on Dec. 16, 2003. The Arizona Power Plant and Transmission Line Siting Committee reviewed the application at a public hearing Feb. 9 and 10, 2004. A special public comment session also was held Feb. 9. Additional hearings were held March 15-16, 2004. View the PV-PW project timeline below for details. On March 16, 2004, the Arizona Transmission Line and Power Plant Siting Committee unanimously granted preliminary approval for the project's CEC. In the hearing process, the Committee approved using the Alternate Route C in the vicinity of the Maricopa County Mobile Planning Area.
