Repsol’s 500MW wind project sparks opposition in Apache County

The fight over Repsol’s Lava Run project now runs through Apache County’s land-use process, state siting reviews and a growing public backlash in the White Mountains, where residents see a 500-megawatt wind proposal as a test of who gets to decide what happens on some of Arizona’s most sensitive ground.

On Dec. 3, 2025, the Arizona Corporation Commission unanimously sent the Lava Run Interconnection Project back to the Arizona Power Plant and Transmission Line Siting Committee so Apache County could weigh in and public concerns could be addressed more fully. A hearing notice describes the interconnection as a 345-kV alternating-current generation tie transmission line, a key piece of infrastructure for moving power out of the county.

That remand matters because the project sits in a county defined by geography and politics. Apache County includes some of Arizona’s highest elevations in the White Mountains and the headwaters of the Little Colorado, Salt River and San Francisco river systems. It was created on Feb. 24, 1879, and is mostly inhabited by members of the Navajo and Apache tribes, making land use, water and wildlife decisions especially sensitive.

Repsol Renewables has tried to sell Lava Run as an economic engine. Project materials say the 500-megawatt wind project would power more than 90,000 Arizona homes each year, while the company’s combined Apache County wind and solar projects would power more than 190,000 homes annually and generate tax and lease payments over time. Repsol also says its broader North America strategy aims for more than 3 gigawatts of installed renewable capacity by 2027.

The company’s western push is backed by a major acquisition. In September 2023, Repsol bought U.S. wind developer ConnectGen from Quantum Capital Group for $768 million, adding a reported 20,000-megawatt development pipeline and marking Repsol’s entry into the U.S. onshore wind market.

But the project has run into a wall of opposition in the White Mountains area, where hearings drew large turnouts and local resistance centered on environmental damage, wildlife impacts and federal land concerns. For residents of Eagar and Springerville, the practical stakes are immediate: viewsheds that help define the region’s tourism appeal, wildfire evacuation routes in a forested mountain corridor, hunting country that supports the local outdoor economy and property values tied to open space and scenery.

The next stage will determine whether Repsol can keep the project moving while answering the county’s land-use and infrastructure concerns, or whether the Lava Run plan becomes another Western renewable project forced to change course under local pressure.
