The California Public Utilities Commission at its Jan. 28 meeting is due to look at whether to approve a Southern California Edison request for approval of two renewables portfolio standard (RPS)-eligible power purchase agreements (PPAs) with two wind projects that are located out of state.
The commission is being asked to approve cost recovery for the long-term renewable energy power purchase agreements between SCE and Broadview Energy JN LLC and Broadview Energy KW LLC. The Broadview JN Project is located in Curry County, New Mexico, and Deaf Smith County, Texas. The Broadview KW Project is located in Curry County, New Mexico. Both projects will be developed by Pattern Energy Group LP and will interconnect with the Tres Amigo Balancing Area at the Tres Amigas 345 kV AC Substation.
SCE in October 2015, requested California commission review and approval of these two 20-year renewable energy PPAs. The Broadview PPAs resulted from SCE’s 2014 RPS solicitation and were executed in August 2015. The contract capacity for the Broadview JN Project is approximately 182 MW and 143 MW for the Broadview KW Project.
Pursuant to the Broadview PPAs, SCE is to begin purchasing generation from the Broadview facilities beginning Dec. 1, 2016. The expected annual generation to be purchased from Broadview JN is 769 Gigawatt-hours (GWh) and 604 GWh from Broadview KW. The generation could count towards SCE’s RPS requirements beginning in December 2016.
“The Broadview projects will use wind turbines that have been technically proven on utility-scale generation projects,” said a draft resolution that the commission is due to vote on. “Additionally, given the projects’ locations being in a high-quality wind region and associated resource quality, SCE believes that Broadview will be able to meet the terms of the PPA.”
The Broadview projects are in a new balancing area, which is being formed by Tres Amigas in Curry County, N.M. Broadview executed interconnection agreements and long-term firm transmission service agreements for the full contract capacity with Tres Amigas in September 2015.
Tres Amigas LLC and Western Interconnect LLC in September 2015 filed with the Federal Energy Regulatory Commission various agreements related to plans for an interconnecting power line in New Mexico that will handle about 1,100 MW of new wind capacity built near the town of Clovis in the eastern part of the state. Western Interconnect will be majority owned by Pattern Energy Group LP. The agreements are with Broadview Energy KW LLC and Broadview Energy JN LLC, developers of two wind projects known collectively as the “Broadview Projects.” A third such developer is Grady Wind Energy Center LLC, which has its own wind project.
The three projects would total 497 MW of transmission capacity, and would transmit power over a 345-kV (ac) transmission line with a maximum capacity of 1,100 MW that would stretch for 35 miles from the wind power sites to Public Service Co. of New Mexico‘s 345-kV Blackwater switching station. The filing said the Broadview Projects have power purchase agreements with an unnamed party (a “California investor-owned utility’), with a PPA imminent for the Grady Project with an unnamed California municipal offtaker.
Large Generator Interconnection Agreements attached to the September 2015 filing describe each of these three projects this way:
- Broadview Energy KW – “The Generating Facility, to be located in Clovis, New Mexico, shall have a nameplate capacity of 142.6 MW, composed of 62 Siemens wind turbine generators of 2.3 MW each. The anticipated Commercial Operation Date of the Generating Facility is January 1, 2017.”
- Broadview Energy JN – “The Generating Facility, to be located in Clovis, New Mexico, shall have a nameplate capacity of 181.7 MW, composed of 79 Siemens wind turbine generators of 2.3 MW each. The anticipated Commercial Operation Date of the Generating Facility is January 1, 2017.”
- Grady Wind Energy Center – “The Generating Facility, to be located in Clovis, New Mexico, shall have a nameplate capacity of 220.8 MW, composed of 96 Siemens wind turbine generators of 2.3 MW each. The anticipated Commercial Operation Date of the Generating Facility is January 1, 2017.”
