Arizona commission considers UNS Electric deal for 75-MW solar project

The Arizona Corporation Commission website shows that the docket is still open on an Aug. 31 application from UNS Electric Inc. for approval of a solar project power purchase agreement with LS-Cliffrose LLC.

Under the agreement, UNS Electric would purchase the entire output of energy from a PURPA Qualifying Facility owned by Cliffrose. Cliffrose is a special purpose entity formed to develop, design, construct, own (or lease) and operate a photovoltaic (PV) facility in Mohave County, Arizona (or such other county within Arizona as mutually agreed by UNS Electric and Cliffrose that is within the UNS Electric service territory). Cliffrose has requested to interconnect the facility to UNS Electric’s 69-kV transmission system with a capacity up to 75 MW (ac).

On June 23, Cliffrose and UNS Electric entered into the agreement, which provides for the sale and purchase of the full output of the facility through Dec. 31, 2039, at the contract price for delivered power and milestones set forth in the agreement. The contract price is based on UNS Electric’s avoided costs.  

UNS Electric said in the Aug. 31 application that under commission policy, if the commission does not act within 30 days after receipt of the agreement, approval of the contract is considered granted. Commission staff on Sept. 16 reported to the commission that it had worked out with the company an extension to the 30-day deadline so that staff could have more time to review the deal, and that the extension would run until the commission’s Dec. 8-9 meeting.

The project contact information in the agreement is: LS-Cliffrose LLC c/o Longview Solar LLC, 1080 W. Ewing Place, Suite 300B, Seattle, WA 98119, Attention: Jason Evans, Telephone: 206-708-6055, jason.evans@tuusso.com.
