If you work in geothermal, the key question is no longer whether federal incentives exist, but which incentive applies, to which project type, and under what ownership structure. The law that changed the timeline To understand where things stand in 2026, you have to start with the Inflation Reduction Act of 2022, which created a long runway for clean e...
Zanskar Advances Arizona Geothermal Project as Arizona Oil and Gas Conservation Commission Approves New Wells
Zanskar’s geothermal ambitions in Arizona gain momentum after the Arizona Oil and Gas Conservation Commission approved new exploration wells tied to the landmark MILESHIGH project near the Morenci copper mine. By: Robert Buluma Arizona’s Geothermal Ambitions Surge Forward as New Wells Approved for Landmark Copper Mine Project Arizona is no longer sitting quietly on the sidelines of America’s geothermal revolution. In a development that could reshape both the state’s mining industry and its clean energy future, regulators have approved new geothermal exploration wells tied to the ambitious MILESHIGH geothermal project in Greenlee County. The approval signals far more than another drilling authorization—it represents a decisive step toward integrating geothermal energy into one of North America’s largest copper mining operations while potentially opening a new chapter for geothermal development across the American Southwest. The newly approved wells are associated with a groundbre...
