Arizona Solar One LLC, which controls a newly-completed solar power project in Arizona, filed on Dec. 11 at the Federal Energy Regulatory Commission for certain related approvals.
It is seeking a waiver from the requirement of Order Nos. 888 and 890 to file an open access transmission tariff (OATT), the requirement of Order No. 889 to establish an Open-Access Same Time Information System (OASIS), and from the Standards of Conduct under Part 358 of the commission’s regulations. Arizona Solar said it is requesting the waivers at the request of the commission staff.
Arizona Solar owns and operates a 250 MW (net) concentrated solar generating facility with thermal energy storage located in Gila Bend, Ariz. (called the “Arizona Solar Facility”). The Arizona Solar Facility commenced operations in October 2013
The facility is located within the balancing authority area of Arizona Public Service (APS) and Arizona Solar sells the entire output of the facility to APS under a long-term power purchase agreement. The commission previously authorized Arizona Solar to sell electric power at market-based rates.
A related interconnection line is an approximately 20.1-mile 230 kV generation tie line, running from Arizona Solar facility’s switchyard to APS’s Panda 230-kV switching station.
