Geothermal resource rights are the legal interests that let someone extract underground heat, steam, hot water, and the minerals dissolved in geothermal fluids. Who holds those rights depends on two things: how the jurisdiction classifies geothermal resources under property law, and whether the surface and subsurface estates have been split. On federal land, the rights come through a Bureau of Land Management lease and a separate drilling permit. On private and state land, ownership usually tracks the mineral estate, but the rules vary by state.
What Geothermal Rights Actually Cover
Federal law defines geothermal resources broadly. Under the Geothermal Steam Act, the term covers indigenous steam, hot water, and hot brines; steam, gases, and heated fluids that come back up after water or gas is artificially pumped into a geothermal formation; the heat energy itself; and byproducts extracted along with the fluid.1Office of the Law Revision Counsel. 30 USC 1001 – Definitions Byproducts include dissolved minerals such as silica or lithium, but not oil, natural gas, or helium. A dissolved mineral only qualifies as a geothermal byproduct if its value is less than 75 percent of the value of the steam itself.
This scope matters. A holder of geothermal rights can access not only steam for generating electricity but also the commercially valuable minerals that come up with the fluid, which can change the economics of a project.
Is Geothermal a Mineral, Water, or Something Else?
Geothermal resources do not fit cleanly into traditional property law categories, and the category a jurisdiction picks controls who owns them and how they are regulated. Three approaches are in use.
Some jurisdictions treat geothermal fluid as a water resource, subjecting developers to appropriation and permitting rules built for aquifer management. Others focus on the heat and regulate extraction like oil and gas. A growing number classify geothermal as sui generis, a Latin phrase meaning “of its own kind.” Under the sui generis approach, geothermal is neither purely mineral nor purely water, and the surface landowner generally holds the rights unless they were previously severed or conveyed.
The choice has direct practical consequences. Mineral-style regulation focuses on reservoir pressure and production limits. Water-style regulation forces developers to secure water rights and prove they will not deplete drinking water aquifers or interfere with existing users. The sui generis approach avoids both frames but sends developers to geothermal-specific statutes instead of well-established mineral or water law.
Ownership on Split-Estate Land
Ownership gets complicated when one party holds the surface and another holds the minerals beneath it. This split estate is common across the western United States, where the federal government historically sold surface rights while reserving mineral interests. Federal courts have held that geothermal resources fall within mineral reservations under homestead-era land patents, so the mineral estate holder controls extraction even though someone else owns the surface.2Office of the Law Revision Counsel. 30 USC 1002 – Lands Subject to Geothermal Leasing
State courts have generally reached similar conclusions when interpreting private deeds that grant “all minerals.” The reasoning is that geothermal resources are commercially valuable substances taken from below the surface for their energy content, which puts them closer to the mineral estate than to surface soil or ordinary groundwater. Courts have distinguished geothermal fluids from normal groundwater by pointing out that geothermal systems are typically sealed off from shallow aquifers by thick rock layers, making them geologically separate from the water supplies that surface owners depend on.
Surface owners keep some protections. A mineral rights holder generally cannot destroy or consume the surface estate to extract resources, and most jurisdictions require surface access agreements before drilling. But where a deed or patent reserves minerals without naming geothermal energy, the default presumption in most jurisdictions favors the mineral estate holder. Sorting out these ownership questions before breaking ground is essential; skipping the step risks trespass claims and the loss of infrastructure investment.
Securing Geothermal Rights on Federal Land
The Geothermal Steam Act of 1970, codified at 30 U.S.C. ยงยง 1001 through 1028, governs geothermal development on federal land.3Office of the Law Revision Counsel. 30 USC Chapter 23 – Geothermal Resources The Bureau of Land Management runs the leasing program. Eligible lands include public lands, withdrawn lands, acquired lands, national forests, and lands where the United States kept the geothermal rights when it conveyed the surface.2Office of the Law Revision Counsel. 30 USC 1002 – Lands Subject to Geothermal Leasing The Energy Policy Act of 2005 overhauled the original law, restructuring royalty rates, lease terms, and bidding procedures for leases issued after August 8, 2005.
Competitive and Noncompetitive Leasing
Federal geothermal leases are awarded primarily through competitive bidding. The Bureau of Land Management must hold a competitive lease sale at least every two years in any state with pending nominations, and leases go to the highest qualified bidder.3Office of the Law Revision Counsel. 30 USC Chapter 23 – Geothermal Resources If a competitive sale draws no bids, the tract becomes available for noncompetitive leasing for two years. Noncompetitive leases are awarded first-come, first-served and carry lower initial rental rates, giving smaller developers an entry point in less-proven areas.
No single person, company, or corporation may hold federal geothermal leases covering more than 51,200 acres in any one state. The cap includes both direct holdings and indirect interests.4Office of the Law Revision Counsel. 30 USC 1006 – Acreage Limitations
To apply, an eligible party (a U.S. citizen, an association of citizens, a municipality, or a corporation organized under U.S. or state law) files Form 3200-24 with the Bureau of Land Management, along with a detailed map and specific acreage boundaries.5Bureau of Land Management. Form 3200-24 – Offer to Lease and Lease for Geothermal Resources A nonrefundable filing fee applies, and competitive leases carry a separate nomination fee when the tract is proposed for sale. Errors in the land description can trigger rejection, so precision matters here more than in most government filings.
Lease Term and Work Requirements
A federal geothermal lease runs for a primary term of 10 years. If the lessee meets annual work requirements or makes payments in lieu of work after the tenth year, the Secretary of the Interior extends the lease for an initial five years. Meeting the work requirements during that first extension earns another five years.6Office of the Law Revision Counsel. 30 USC 1005 – Lease Term and Work Commitment Requirements
Work requirements are meant to push lessees toward commercial production rather than letting them sit on promising land. After year ten, the lessee must show the tract has geothermal potential, then confirm that producible resources actually exist. The Secretary can allow annual payments to substitute for physical work, but only for a limited number of years. Once a well begins producing in commercial quantities, the work requirements drop away.6Office of the Law Revision Counsel. 30 USC 1005 – Lease Term and Work Commitment Requirements
A separate rule helps lessees who are actively drilling when the primary term ends. If actual drilling operations began before the term expired and are being diligently pursued, the lease extends for five years and then continues as long as geothermal energy is produced or used commercially, up to 35 additional years.6Office of the Law Revision Counsel. 30 USC 1005 – Lease Term and Work Commitment Requirements
What a Federal Lease Costs
Federal geothermal rights come with ongoing financial obligations: annual rent, production royalties, and reclamation bonds.
Rental rates depend on how the lease was acquired. For leases issued after August 8, 2005, competitive lessees pay $2 per acre in year one and $3 per acre in years two through ten. Noncompetitive lessees pay $1 per acre for the first ten years. After year ten, the rate rises to $5 per acre regardless of how the lease was acquired. Partial acreage rounds up to the next whole acre.7eCFR. 43 CFR Part 3200 Subpart 3211 – Filing and Processing Fees, Rent, Direct Use Fees, and Royalties
Royalty rates depend on what the lessee sells. When a lessee or affiliate sells electricity generated from the leased resource, the royalty is 1.75 percent for the first ten years of production and 3.5 percent after that. When the lessee instead sells the raw geothermal resource at arm’s length to a buyer who generates electricity, the royalty is 10 percent.8eCFR. 43 CFR 3211.17 – Royalty Rate on Geothermal Resources for Commercial Electricity Generation The gap creates a strong incentive to build and operate generating facilities rather than selling steam or brine.
Before any physical work begins, the lessee must post a reclamation bond. Minimum amounts scale with the operation: $5,000 for a single exploration operation, $25,000 statewide, or $50,000 nationwide; $10,000 per lease for drilling, $50,000 statewide, or $150,000 nationwide; and at least $100,000 for an electrical generation facility. Direct-use facilities have bond amounts set case-by-case by the Bureau of Land Management. These are floors, not ceilings. The agency can raise them where the operator has a history of noncompliance, owes unpaid royalties, or where estimated reclamation costs exceed the standard amount.9eCFR. 43 CFR Part 3200 – Geothermal Resource Leasing
The Lease Is Not Permission to Drill
Holding a federal lease and having permission to drill are two different things. Before turning any ground, the lessee must obtain a Geothermal Drilling Permit by submitting Standard Form 3260-2, an operations plan describing the project scope, a complete drilling program with technical specifications, and proof of an acceptable bond. Environmental review under the National Environmental Policy Act must be complete before the Bureau of Land Management approves the permit.10Permitting Dashboard. Geothermal Drilling Permit GDP
The lease secures your exclusive right to develop geothermal resources on a tract. The drilling permit is the separate approval to actually disturb the ground. Drilling without the permit is a compliance violation that can jeopardize both the permit application and the lease itself.
Environmental Review That Gates the Permit
Federal geothermal projects trigger environmental review at several points, and the scrutiny grows as a project moves from leasing to exploration to full-scale development. The National Environmental Policy Act requires the Bureau of Land Management to assess environmental impacts before issuing leases, approving exploration plans, or authorizing drilling and power plant construction. Low-impact activities such as preliminary surveys may qualify for a categorical exclusion. Exploration drilling often calls for an environmental assessment. Large operations like power plants and transmission lines typically require an environmental assessment at minimum, and a full environmental impact statement is common.
When a project could affect threatened or endangered species or their habitat, Section 7 of the Endangered Species Act requires the authorizing agency to consult with the U.S. Fish and Wildlife Service or NOAA Fisheries.11Office of the Law Revision Counsel. 16 USC 1536 – Interagency Cooperation Formal consultation can take 90 days or longer. The wildlife agency may issue an incidental take statement that allows limited harm to protected species as long as the developer follows specified mitigation measures. Species reviews can add months to the permitting timeline, so early identification of species concerns pays off.
State Authority Over Private and State Land
The federal framework covers federal land. Geothermal development on state-owned and private land is controlled by state law, and the differences among states are significant. Some states run geothermal regulation through their existing oil and gas commissions, focusing on reservoir management and production limits. Others route it through water resource agencies and require developers to secure water rights and show that extraction will not harm local aquifers. States that adopted a sui generis classification often created standalone geothermal statutes with dedicated permitting agencies.
Whatever the regulatory home, most state programs share common features: well construction standards to prevent groundwater contamination, drilling permits with site-specific conditions, and ongoing reporting obligations. Many states also require reinjection of spent geothermal fluids to protect groundwater and maintain reservoir sustainability. Permit fees vary widely, so contact the relevant state agency early in project planning.
When a Reservoir Crosses Multiple Leases
Geothermal reservoirs rarely respect lease boundaries. When one spans multiple federal leases, the Secretary of the Interior can authorize or require lessees to operate under a unit agreement. Lessees pool their interests and coordinate drilling, production, and reinjection across the whole reservoir instead of developing tracts independently. A majority interest in any single lease can commit that lease to a unit agreement.12Office of the Law Revision Counsel. 30 USC 1017 – Unit and Communitization Agreements
Unit agreements are reviewed at least every five years. During review, the Secretary can remove land that is no longer reasonably necessary for operations, based on scientific evidence, and retains authority to adjust production rates and development schedules. Unitization cuts redundant drilling and helps manage reservoir pressure across a field, but it also means giving up some operational independence and accepting government oversight of production planning.12Office of the Law Revision Counsel. 30 USC 1017 – Unit and Communitization Agreements
