A 400-megawatt solar-and-storage project just took a big step toward rising out of the desert south of Pahrump, and not everyone is thrilled about the view.
The Bureau of Land Management has signed off on a final environmental review for the Purple Sage Energy Center, clearing a major regulatory hurdle for the massive plant on public land in the South Pahrump Valley. The move has reignited a fierce local fight over Mojave desert tortoise habitat, Ice Age fossils and already stressed groundwater.
On June 12 the agency released its Final Environmental Impact Statement and a related resource-management plan amendment for the project, which would cover roughly 4,534 acres of BLM-managed land and is now in a 30-day protest period that runs through July 13, 2026, according to the BLM. If the plan survives protests, the applicant could construct a solar facility with integrated battery storage and a gen-tie line to the Trout Canyon substation.
Who’s Building and Who Would Buy the Power
The proposal pairs about 400 megawatts of photovoltaic panels with utility-scale batteries. Developer Primergy has already locked in a long-term power purchase agreement with San Diego Community Power for the facility’s full output, listing a 1.6-gigawatt-hour battery system as part of the deal.
Primergy estimates the project will generate roughly $90 million in local tax payments over its lifetime. State paperwork reviewed by the Nevada Department of Taxation identifies Noble Solar LLC as the project operator and pegs annual net production at about 1,211,946 megawatt-hours, with commercial operation expected around November 2027.
Environmental Tradeoffs and Local Pushback
Conservation groups say that footprint comes with a hefty ecological price tag. The final review estimates construction would permanently degrade nearly 860 acres of existing habitat, according to News From The States.
Basin and Range Watch and other local advocates warn the project could displace threatened Mojave desert tortoises, damage mesquite woodlands and disturb Ice Age fossils. Those concerns surfaced repeatedly in public comments during the environmental review, as residents questioned whether clean energy here would come at too high a cost to the desert around them.
Water, Wildfire Risks and Mitigation
Water use is another flash point. Documents and local reporting indicate the construction phase would need hundreds of acre-feet of water, roughly 900 acre-feet over an 18-month buildout, while ongoing operations would use only a few dozen acre-feet annually, according to project filings and reporting by the Pahrump Valley Times.
To blunt those and other impacts, the BLM’s analysis recommends tighter restoration and site-management standards. That includes more aggressive topsoil salvage and native revegetation designed to cut down on invasive grasses and fugitive dust, according to a BLM alternatives report.
Next Steps and Timing
The final EIS notice kicked off a formal 30-day protest window. The Federal Register listing for the document confirms the protest period closes July 13, 2026, and lays out instructions for filing protests through the NEPA Register.
If those protests are not upheld, the agency can issue a Record of Decision and grant a right-of-way for the project. Developers say construction and commissioning would then move forward on the timelines already outlined in public filings.
Backers of Purple Sage point to the project’s delivery of carbon-free power into the CAISO grid and the promised local tax revenue. Opponents counter that those benefits do not make up for the loss of key desert ecosystems. Expect more formal protests and heated public comment in the coming weeks as the future of the South Pahrump Valley is argued panel by panel.
