Latigo Wind Park LLC, which has a 62.1-MW project in Utah that is due in-service this month, filed a Jan. 14 notice with the Federal Energy Regulatory Commission of a change in status due to its affiliation with Sandstone Solar LLC, which owns and operates a solar photovoltaic project with a nameplate rating of about 45 MW (ac) located in Florence, Arizona.
The Sandstone Project is located within the Salt River Project Agricultural Improvement and Power District (SRP) balancing authority area in the Southwest region. The Sandstone Project reached commercial operation in January 2016. Sandstone has obtained market-based rate authority and is an exempt wholesale generator under the Public Utility Holding Company Act of 2005. Sandstone is committed to sell the entire output of the project under a 21-year power purchase agreement with SRP.
Latigo Wind Park’s project is located in the PacifiCorp-West (PACW) balancing authority in the Northwest region. It and Sandstone own zero (0) MW of uncommitted capacity in the SRP market or the PACW market, or in any first-tier markets thereto. Therefore, the Sandstone Project contributes no uncommitted capacity to Latigo Wind Park’s horizontal market power, and thus no update to their respective market screens is warranted, the company said.
Latigo is controlled by Sustainable Power Group LLC, while Sandstone is controlled by WFS Solar Managing Member 1 LLC.
FERC on Dec. 15 had approved an Oct. 29 application from Sandstone Solar LLC covering the acquisition by WFS Solar Holdings 1 LLC of 100% of the membership interests in Sandstone Solar.
