Decision Focus
On August 4, 2026, the Bureau of Land Management formally announced its intent to prepare an environmental analysis and resource management plan for the Mosey Solar Project—a 500 MW facility proposed on more than 3,500 acres of public land in Clark and Nye counties, Nevada. The project’s developer, Clearway Energy Group, explicitly frames it as supply for data centers and AI-related development in the western United States. For Global Heads of Data Center Energy, the operational signal is this: a large-scale western solar project designed with your load profile in mind has cleared one of the hardest permitting gates in the current federal environment, but it arrives with a timeline that starts in 2027 and ends in August 2029 at the earliest.
90-Second Brief
As the week closes, bLM’s environmental review announcement is the project’s clearest forward motion after the Trump administration’s “Unleashing American Energy” executive order froze most public-land renewable permitting. Clearway’s development plan names data centers and AI as the primary end-use case. Construction is projected to begin in early 2027 and complete by August 2029. The project remains subject to a separate executive order targeting wind and solar tax credits and a secretary order requiring personal sign-off from the Interior Secretary on public-land solar, meaning permitting risk has narrowed but has not closed.
What Is Really Happening?
The Mosey project’s advance is not a policy reversal; it is a selective exception inside a still-constrained system. The Department of the Interior’s requirement that Interior Secretary Doug Burgum personally approve all solar and wind projects on public land continues to apply. What changed is that BLM has determined the Mosey project is eligible to proceed to environmental analysis—a necessary precondition before any approval decision reaches the Secretary’s desk.
Two adjacent developments add structural support. In June 2026, upgrades to the GridLiance West Core Transmission Line Project covering Nye and Clark counties received approval, increasing regional transmission capacity. That matters because stranded generation—solar built without confirmed transmission headroom—is already a realized risk in several western markets. Mosey’s location in a corridor where transmission upgrades are already moving is a meaningful differentiator from other frozen projects in the region.
Nevada Governor Lombardo has also actively lobbied federal counterparts to advance stalled state projects, including Mosey, framing them as essential to state economic growth. State-level political alignment with federal permitting decisions has materially shortened review cycles on comparable projects elsewhere, and that pressure is documented here.
Why It Matters for Global Heads of Data Center Energy
The explicit naming of data centers and AI load in Clearway’s development plan is not marketing language—it is a procurement signal. Projects sized at 500 MW and positioned near existing transmission upgrades in the Nevada-California corridor are the category of asset worth tracking for long-term offtake conversations, whether structured as a PPA, a VPPA, or an ownership stake.
The timeline defines your window. If construction starts in early 2027 and completes in August 2029, financial close and offtake agreements need to be structured well before ground breaks—making procurement conversations relevant now, not in 2027. Any energy head modeling western load growth for AI infrastructure, particularly in markets connected to CAISO or serving Nevada-based facilities, should treat this as an active procurement target rather than a future watch item.
The regional transmission picture reinforces that view. The GridLiance upgrade approved in June adds capacity to the same geographic corridor. Projects with confirmed or developing transmission paths carry less interconnection queue risk than those waiting on undefined grid access, and that variable directly affects which PPAs your team can realistically book against contracted load.
Forward View
Three fronts are worth tracking as this moves through NEPA. First, the groundwater evaluation by the National Park Service and the U.S. Fish and Wildlife Service is not a formality. The Pahrump Valley Basin is hydrologically connected to Devils Hole and the Ash Meadows National Wildlife Refuge. If agency review surfaces material groundwater impact findings, construction timelines shift, and any procurement position built around a 2029 delivery date should carry an explicit schedule buffer.
Second, the tortoise connectivity risk is a live permit condition, not a settled one. The Trout Canyon Tortoise Connectivity Zone is actively managed by BLM as high-priority habitat. Conservation litigation has delayed comparable Nevada projects by 12 to 24 months in recent cycles, and that litigation pathway remains open here.
Third, the executive order mandating review of wind and solar tax credits has not been resolved. If federal credit structures change materially before financial close, Clearway’s project economics—and by extension, any PPA pricing anchored to current cost assumptions—could shift. That basis risk is worth pricing into any preliminary offtake conversation.
What Is Still Uncertain
The Interior Secretary’s personal approval requirement has not been removed from this project—it has simply not yet been triggered. How Burgum’s office processes Mosey after the environmental analysis is complete is not predictable from current signals. The duration and outcome of the NEPA review is likewise unspecified; BLM is accepting public comments through the end of the month, but the review timeline from that point has not been stated. The project’s offtake structure and any existing anchor customer commitments have not been disclosed publicly. Whether Clearway has a data center operator already in commercial conversations or is positioning speculatively for market demand is not confirmed by available evidence.
One Question for Your Team
Given the 2029 delivery target, the live permitting risk, and the explicit data center framing in Clearway’s development plan—does your current western US procurement pipeline carry enough optionality to absorb a 12-to-24-month schedule slip on any single asset of this scale, or are you already building against a capacity assumption that depends on Mosey delivering on time?
