Open season held on Western Interconnect’s New Mexico transmission project

Western Interconnect LLC (WI) said Oct. 17 that it has launched on Oct. 3 an Open Season process to allocate up to 603 MW of transmission rights on its proposed transmission line in New Mexico.

Through this Open Season, WI will solicit Transmission Service Requests (TSR) from parties willing to acquire firm transmission service rights at the same rates, terms and conditions as offered to anchor customers on the line. The TSR submission window will conclude on Nov. 11.

WI is building a 35-mile, single-circuit 345-kV (AC) merchant transmission line connecting Public Service Co. of New Mexico‘s Blackwater substation to a new 345-kV switching station located northeast of Clovis in Curry County, New Mexico. The normal transfer capacity of the line will be 1,100 MW, and commercial operations are scheduled to begin on Jan. 1, 2017.

Western Interconnect was formed by Tres Amigas LLC (TA) and renewable energy company Pattern Energy Group LP to develop, finance, construct, own and operate the WI transmission line.

WI is offering to sell up to 603 MW of firm transmission service. The Transmission Service Agreement and Large Generator Interconnection Agreement rates, terms and conditions are detailed on the Open Season website. London Economics International LLC (LEI) has been selected to serve as the Independent Examiner to ensure the absence of any undue discrimination or undue preference during the process.

LEI, TA and WI will evaluate all submissions to verify that they meet the minimum eligibility requirements as detailed on the Open Season website. In the event that the total amount of conforming TSRs exceeds available transmission capacity on the WI, LEI will use the ranking methodology detailed on the Open Season website to select among conforming TSR submissions. Selected applicants will be notified within two weeks following close of the Open Season TSR submission window.

Pattern Energy Group is an independent power company listed on The NASDAQ Global Select Market and Toronto Stock Exchange. The company specializes in wind, solar, and transmission projects in the United States, Canada, Mexico, Chile and Japan.

Tres Amigas LLC is focused on providing the first common interconnection of America’s three power grids to help the country achieve its renewable energy goals and facilitate the smooth, reliable and efficient transfer of power from region to region.
