California ISO concurs with revisions to interconnect deal for 500-MW solar project

The California Independent System Operator filed on Feb. 25 at the Federal Energy Regulatory Commission a Certificate of Concurrence with respect to a Large Generator Interconnection Agreement with NextEra Desert Center Blythe LLC and Southern California Edison (SCE).

“On February 18, 2015, SCE submitted the NextEra LGIA in Docket No. ER15- 1058-000, with a requested effective date of February 19, 2015,” said CAISO about the reason for this new filing. “In that filing, SCE explained that it was amending the NextEra LGIA to eliminate access concerns at SCE’s Colorado River Substation for future interconnection customers’ generation tielines. SCE recommended, and the parties agreed, to modify the interconnection configuration to eliminate NextEra’s proposed ring bus switchyard described in the currently-effective agreement. The elimination of NextEra’s proposed ring bus switchyard results in the project having two separate 220kV generation tie lines terminating at SCE’s Colorado River Substation. This change requires SCE to engineer, design, procure, and construct a second line position at the Colorado River Substation for the generation tie-line interconnecting the McCoy Station to the Colorado River Substation. SCE’s filing is pending before the commission.”

Rather than submit the same LGIA under its own name, CAISO said that it concurs with what SCE filed on Feb. 18.

The revised LGIA filed on Feb. 18 provides the terms and conditions pursuant to which SCE and the CAISO will provide Interconnection Service for NextEra’s 500-MW generating facility located near Blythe, California, named the Genesis McCoy Solar Project. The project will interconnect to SCE’s Colorado River 500/220 kV Substation. The original LGIA was accepted for filing by FERC in 2011.
