Second phase of Agua Caliente solar project excised from interconnect deal

Arizona Public Service on Nov. 20 filed with the Federal Energy Regulatory Commission Amendment No. 2 to the Large Generator Interconnection Agreement with Agua Caliente Solar LLC, Imperial Irrigation District, San Diego Gas & Electric and the California Independent System Operator related to termination of a second phase of a major solar project.

In May 2010, the parties submitted the original LGIA to FERC, which was accepted by the commission with an effective date of July 28, 2010. The parties entered into the Agreement to facilitate an interconnection of a proposed solar photovoltaic Large Generating Facility to the Hassayampa-North Gila 500-kV transmission line. This facility was to be constructed in two phases: Phase A was to be a 290-MW project to be constructed by Agua Caliente Solar; and Phase B was to be a 210-MW project to be constructed by North Gila River Development LLC.

APS filed Amendment No. 1 in September 2011,which removed all Reliability Management System language from the agreement to comply with the requirements specified in the FERC Order in Docket Number ER11-2949-000, as a result of the Western Electricity Coordinating Council’s (WECC) requested termination of the Reliability Criteria Agreement and that all parties remove the RMS requirements from agreements within a year of WECC’s notification.

“On January 14, 2014, the Interconnection Request for Phase B of the Large Generating Facility was withdrawn.,” said APS in the Nov. 20 filing. “As a result of the withdrawal, the Parties hereto have agreed to enter into this Amendment No. 2 to the Agreement in order to remove all references to Phases A and B since only a single project remains; to remove all Phase B language and all obligations related to Phase B; and to remove North Gila River Development, LLC, as a Party to the LGIA.”
