Wind and Solar Leasing on Trust Land in Sioux County, North Dakota

Because Sioux County sits entirely inside the Standing Rock Sioux Reservation, wind and solar development here runs through tribal trust-land leasing, not a conventional county land-lease process. Since 2021, the Standing Rock Sioux Tribe has had the federal authority to approve its own renewable-energy leases on trust land directly -- and it is actively using that authority on real, named projects.

This page covers what's specific to Sioux County. For the general explanation, see the national guide.

The Tribe can approve its own wind and solar leases -- since April 2021

On April 14, 2021, the Bureau of Indian Affairs approved leasing regulations the Standing Rock Sioux Tribe submitted under the federal HEARTH Act of 2012, authorizing the Tribe to enter into business, residential, and wind-and-solar leases on its own trust lands without a separate BIA approval required for each individual lease. That's a meaningful change from the standard trust-land leasing process described in the hub's general trust-land coverage: for renewable-energy leases specifically, Standing Rock now controls its own approval process rather than routing every lease back through the federal government. For a landowner or developer evaluating wind or solar potential involving trust land in Sioux County, this means the Tribe itself -- not the BIA -- is the primary point of contact and decision-maker for lease terms.

Real projects already using that authority

The Tribe has moved beyond the regulatory framework into actual projects. Its flagship effort is Anpetu Wi ("morning light"), a planned 235-megawatt, 60-turbine wind farm intended to provide clean energy and economic development revenue for the community. Separately, the Tribe has designed a much smaller community-scale wind turbine (in the 1.7 to 2.4 MW range) with potential siting near Prairie Knights Resort north of Fort Yates, projected to generate roughly 6 million kilowatt-hours of electricity annually -- enough to meaningfully offset local building loads rather than feed a regional grid. On the solar side, the Tribe has pursued roughly 630 kilowatts of solar generation capacity installed on tribal buildings across its North Dakota land.

None of this changes how a private, fee-land parcel in Sioux County is bought or sold, but it does shape the practical landscape for anyone with wind or solar interests here: expect an active tribal energy-development program, a Tribe that has both the legal authority and a track record of executing renewable projects on trust land, and a leasing relationship for trust land that runs through Standing Rock's own government rather than a conventional private wind-lease negotiation. If you're evaluating a fee-land parcel near planned or existing tribal renewable-energy infrastructure, ask both the Tribe's energy office and the BIA Standing Rock Agency about current project boundaries and any transmission or access easements that might cross or approach your parcel.
