How to Bring a Geothermal Well Back from the Dead
Geothermal company Zanskar successfully revitalized a failing power plant in New Mexico by using advanced drilling techniques and AI. This success suggests that older, underperforming geothermal sites may hold significant untapped potential for renewable energy production.
Why it matters
Revitalizing existing geothermal infrastructure could help the industry overcome geographic and economic barriers to scaling renewable baseload power.
Geothermal company Zanskar bought a New Mexico power plant in 2024 that appeared from the outside to be failing. The shallow wells had been rapidly losing heat, and the plant was having trouble generating power as a result.
Now, after drilling a new well and operating the power plant for a full year, Zanskar says that it has made a complete turnaround. The Lightning Dock site, according to figures from the company shared exclusively with WIRED, has become one of the most productive pumped geothermal wells in the US, providing enough heat to run the power plant with no issues.
The productivity over the past year at the Lightning Dock site “fundamentally changes how people think about these types of systems that we really thought we understood in the past,” says Zanskar cofounder Joel Edwards.
