BLM Approves Construction of 3.2GW Starwood Arizona-California Transmission Line
The Bureau of Land Management has told a subsidiary of Starwood Energy Group Global that it can begin building a 500 kV transmission line between Arizona and California, a region rich in solar potential, the U.S. Department said Thursday. inside.
The Ten West Link project, which is expected to handle 3,200 MW, grew out of the California independent system operator’s transmission planning process. After discovering that the approximately $400 million project would bring economic benefits, CAISO launched a solicitation process in 2014 and awarded the project to Delaney Colorado River Transmission, a subsidiary of Starwood, a private equity firm.
The project will support the development of large-scale solar resources and boost the reliability of central Arizona and southern California’s mass power system, according to the Department of the Interior.
Overview of the dive:
The Ten West Link project is expected to travel 125 miles between the Delaney substation near Tonopah, Arizona, and the Colorado River substation in Blythe, California. It will be built next to an existing transmission line.
When CAISO evaluated the project, the grid operator found it would reduce costs for California ratepayers by accessing cheaper electricity in Arizona, the California Public Utilities Commission said in its November 2021 report. decision project approval.
Among the benefits of the project, Delaney Colorado River Transmission expects it to reduce CAISO’s need to reduce renewable energy generation on its system, according to the PUC.
The transmission company also said the project would increase the benefits of the Western Energy Imbalance Market, or EIM, for CAISO and Arizona Public Service Co. The transmission line will allow for increased electricity sales between the grid operator and the Phoenix-based utility in the EIM.
“The approval of this new transmission line on our public lands will accelerate our nation’s transition to a clean energy economy by unlocking renewable resources, creating jobs, reducing costs and boosting local economies,” Interior Secretary Deb Haaland said in a statement.
The BLM is processing applications for 64 solar, wind and geothermal projects in the West totaling 41,000 MW, according to the department.
The agency is also conducting preliminary reviews of 90 solar and wind applications as well as 51 wind and solar power test applications on federal lands, the department said.
The BLM’s “notice to proceed” is another sign that transmission projects are moving forward in the West.
The BLM in May published a draft environmental impact statement for the 500 kV SunZia transmission project, which is expected to deliver 4.5 GW of mostly renewable power, and began reviewing proposed projects in Nevada and Utah in April.
