Agreements filed with FERC for 500 MW of wind development in New Mexico

Tres Amigas LLC and Western Interconnect LLC on Sept. 11 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 that Tres Amigas now holds these agreements and will later transfer them to Western Interconnect. That transfer will aid the financing for this new transmission line.

Pattern Energy Group LP, known as Pattern Development, will be the upstream owner of the three wind projects. 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.

Since 2013, National Renewable Solutions LLC had been developing the three wind projects, then in July of this year Pattern Development bought the development rights and transmission queue positions for the Broadview Projects, and expects to close a deal in the next six weeks for the Grady Project, the filing noted.

Tres Amigas plans an “open season” in late 2015 or early 2016 for the capacity of the 1,100-MW transmission line not taken up by these three initial wind projects.

Large Generator Interconnection Agreements attached to the Sept. 11 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.”
