A Clean Line Energy Partners spokesperson on April 10 told TransmissionHub that it is expected that the approximately $150m, 150-mile Western Spirit Clean Line will receive all major permits and approvals by summer.
Western Spirit will also obtain ministerial pre-construction permits prior to the start of construction, she said. The project – which according to its website is a 345-kV high voltage alternating current transmission line – is expected to be in service in December 2020, the spokesperson noted.
The New Mexico Public Regulation Commission, in an April 4 final order, approved New Mexico Renewable Energy Transmission Authority’s (RETA) December 2017 application seeking a determination that the “Western Spirit Transmission Project” will not materially diminish electric service reliability of the transmission system in New Mexico.
As noted in the order, RETA’s application indicates that the line would extend from Torrance County near Corona to Public Service Company of New Mexico’s (PNM) Rio Puerco substation. The project – which is a joint enterprise between RETA and Clean Line Energy Partners – would collect renewable power from eastern New Mexico and deliver up to 1,000 MW to central/western New Mexico and energy markets further west.
The commission added in the order that before the project may be built, the commission must make a determination that the project “does not materially diminish electric service reliability of the transmission system in New Mexico.”
RETA’s application is supported by the transmission construction and interconnection agreement between PNM and Western Spirit, as well as a system impact study and interconnection facilities study, the commission said.
“Based on these studies, the commission finds … that construction and interconnection of the project will not materially diminish electric service reliability of the transmission system in New Mexico,” the commission said.
