BLM Approves Renewable Power Transmission Line in Maricopa County
The Bureau of Land Management has issued a final decision on a proposed 500-kilovolt transmission line crossing public lands about 60 miles west of Phoenix in Maricopa County. Once completed, the transmission line will support the supply of utility-scale solar power from the 150 megawatt Harquahala Sun solar generation facility into the grid.
HV Sunrise, LLC applied for a 30-year right-of-way grant to construct, operate and maintain the transmission tie line. The BLM evaluated several routes in the environmental assessment and selected the preferred route which crosses approximately 1.14 miles of BLM land. Gen-Tie lines like the one approved today are essential to help connect clean energy projects on non-federal lands to the grid.
“This project facilitates the transmission of renewable energy in Arizona,” said Phoenix District Manager Leon Thomas. “The approval of this project enables the BLM to support the responsible development of renewable energy.”
When completed, the transmission line will connect the Harquahala Sun Solar Power Generation Facility, a 150 megawatt hybrid solar photovoltaic and battery storage facility located on approximately 1,000 acres in western Maricopa County, to the existing Delaney substation, both located on private land. . Construction on the BLM lot is expected to take about three months.
The BLM manages large tracts of public land that have the potential to make significant contributions to the country’s renewable energy portfolio. To encourage the development of these energy sources, the BLM provides sites for the environmentally sound development of renewable energy on public lands. Efficiently deploying renewable energy from our nation’s public lands is crucial to achieving the Biden-Harris administration’s goal of a carbon-free energy sector by 2035, as well as the direction of Congress in the Energy Act of 2020 to allow 25 gigawatts of solar, wind, and geothermal power onto the public domain by 2025.
The Record of Decision, Final Environmental Assessment and No Significant Impact finding are available on the BLM’s NEPA National Registry.
