The Utah Public Service Commission on Oct. 7 approved Power Purchase Agreements between PacifiCorp and Enterprise Solar LLC, Escalante Solar I LLC, Escalante Solar II LLC and Escalante Solar III LLC.

On July 3, PacifiCorp d/b/a Rocky Mountain Power filed with the commission applications in four separate dockets for approval of these agreements. The PPAs provide for the sale of energy to PacifiCorp to be generated from the Enterprise, Escalante I, Escalante II and Escalante III solar projects located in and around Iron County, Utah, for a period of 20 years.

“Based upon the Applications, the comments filed in these dockets, the testimony provided at the hearing, and the lack of opposition to the Applications, we find the prices, terms and conditions of the PPAs in these dockets are consistent with applicable state laws, relevant Commission orders, and Schedule 38.,” said the Oct. 7 combined approval for all four projects. “Therefore, we conclude the PPAs are just and reasonable and in the public interest.”

First Wind had announced June 19 that it had finalized four 20-year power purchase agreements with PacifiCorp. Under the agreements, the utility will buy the output of the planned 320-MW (ac) Four Brothers solar development, which includes four separate, fully permitted 80-MW (ac) project sites.
