BLM's Utah geothermal sale opens Monday as New Mexico results reset per-acre expectations

The Bureau of Land Management opens its next federal geothermal lease auction in Utah on 18 August 2026 - two days from now - with bidders carrying fresh price signals from a June sale in New Mexico that reset the agency's per-acre benchmark^[1].

What New Mexico established

The BLM's 16 June New Mexico sale netted $16,581,926 in total receipts across 47 parcels covering 152,381 acres, making it the second-highest-grossing geothermal sale in agency history^[1]. The top bid came from Rock Canyon Resources, which paid $701 per acre - $3.14 million - for a single 4,479-acre tract in Sierra County, setting a new federal record for both per-acre price and total value for a single geothermal parcel.

The aggregate result was a structural departure from recent norms. The average winning bid across the 47 sold parcels was $107 per acre, more than triple the $32 per acre average recorded at Nevada's October 2025 sale. The share of parcels clearing at the $2/acre statutory minimum - historically the dominant outcome - fell from 76% of parcels in 2019 to 17% in 2026, according to Enverus Intelligence Research.

Major participants in the June sale included:

• Ormat Technologies
• Zanskar
• Invenergy^[1]

Transmission access is the top pricing variable

Enverus found that geographic resource quality alone did not explain the New Mexico outcome. Proximity to high-voltage transmission lines with available capacity added an estimated $43 per acre in bid value, making grid access the model's strongest single financial driver - ahead of subsurface geothermal gradient.

The firm's principal analyst Graham Bain noted that "competition is now materially moving federal geothermal bids" and that "the window" for locking up acreage at minimum prices "is closing." That framing matters directly for Utah, where the two existing geothermal power plants - Cove Fort and Roosevelt Hot Springs - are both proposing redevelopment and expansion, and where proximity to western transmission corridors varies sharply by parcel.

Utah's prior sale as a reference point

The August 18 auction is not Utah's first recent test of elevated bidder interest. An April 2025 BLM Utah sale leased 14 parcels covering 50,961 acres for $5,663,890 in total receipts, averaging $111.47 per acre - at the time a state record. The highest single-parcel price in that sale reached $344 per acre, paid by Buffalo River Minerals for a tract in Beaver County.

New Mexico's $107/acre average is broadly comparable to Utah's April 2025 result, but the $701/acre outlier and the compression of minimum-bid outcomes suggest the competitive ceiling has moved. Whether Utah's August parcels sit near transmission infrastructure will determine how much of that ceiling is tested on Monday.

What to watch

The BLM conducts the auction online through the Efficient Markets platform. Further geothermal lease sales are scheduled in Nevada in October 2026 and Idaho in November 2026, with Enverus modeling Idaho average bids in a range of $58 to $70 per acre under current grid conditions, rising toward $344 per acre in a transmission-upgrade scenario. The Utah result on 18 August will be the first data point in that sequence since New Mexico reset the baseline.
