SCE terminates interconnect for 850 MW solar project

Southern California Edison (SCE) November 22 filed with the Federal Energy Regulatory Commission (FERC) a notice of cancellation of the large generator interconnection agreement for an 850 MW solar power project.

The agreement was among SCE, power project developer SES Solar One LLC and the California Independent System Operator, according to GenerationHub.

The agreement sets forth the terms and conditions pursuant to which SCE will design, engineer, construct, own, operate and maintain the interconnection facilities required for a proposed 850 MW solar project, to be located in Newberry Springs, San Bernardino County, Calif., to SCE’s electric system at the Pisgah 220 kV Switchyard.

The commission accepted the agreement for filing in April 2010. In September 2011, SES Solar One provided notice of suspension under Article 5.16 of the agreement. Article 2.3.1 states that the plant developer may terminate the agreement at any time by giving the California ISO and SCE 90 calendar days advance written notice.

In accordance with Article 2.3.1 of the agreement, the developer in June of this year then provided notice to SCE and the California ISO requesting termination of the agreement. The June letter from the developer didn’t explain why the agreement should be cancelled, noting that the project has not been built.

SCE said it understands that, in February 2010, SES Solar One LLC merged with its affiliate company Calico Solar LLC and that Calico Solar assumed all rights, title, interest and obligations to the project. K Road Power Holdings LLC, through subsidiary K Road Calico Solar LLC, acquired the Calico Solar Project. The June letter was on the letterhead of K Road Calico Solar.

The now-terminated agreement said the project was to be built in two phases, with a 250-MW first phase, then another 600-MW phase later. The facility would under the 2010 agreement have consisted of 34,000 Stirling System solar dishes, each rated at 25 kW, step-up transformers, meters and metering equipment and appurtenant equipment.

The California Energy Commission website shows that the commission-issued license for this project was terminated on Aug. 27 of this year. The website noted that in 2012, before the license termination, the developer asked to change the technology from the Stirling System solar dishes mentioned in the agreement, to photovoltaic.
