Geo POWER Act
Summary
The Geo POWER Act (S.4116), introduced in the Senate on March 17, 2026, and currently in the Senate Energy and Natural Resources Committee, would establish a Milestone-Based Geothermal Demonstration Program to fund next-generation geothermal projects in low-permeability and impermeable reservoirs, prioritizing regions with limited existing geothermal generation. The bill authorizes innovative financing mechanisms but does not specify a dollar amount, and it remains in early legislative stages with no appropriation attached.

Key Takeaways
- 1.S.4116 is in early-stage committee review; no funding is authorized yet, so no direct near-term revenue impact.
- 2.The bill targets next-generation geothermal in new geologies, prioritizing regions with no current geothermal generation.
- 3.Milestone-based financing reduces upfront risk for developers, potentially lowering project costs.
- 4.Companion bill HR8437 has advanced in the House, but Senate action is pending.
- 5.No specific dollar amount is attached; actual funding requires a separate appropriations bill.
Market Implications
The bill, if enacted with appropriations, would structurally benefit companies with geothermal development exposure, particularly those focused on enhanced geothermal systems (EGS) and new regions. Ormat Technologies is the largest pure-play geothermal operator in the U.S., with a portfolio of geothermal plants and a technology arm that could qualify for milestone-based financing. However, since the bill authorizes no specific funding and remains in committee, near-term market impact is minimal. Investors should monitor the appropriations process and DOE program announcements for catalysts. The bill's emphasis on low-permeability reservoirs could also favor technology providers like Fervo Energy (private) and Baker Hughes, which has geothermal drilling and completions expertise, but these are indirect connections until funding is real.
Full Analysis
The Geo POWER Act (S.4116) was introduced in the Senate on March 17, 2026, by Senator Hickenlooper (D-CO) with bipartisan cosponsor Senator Curtis (R-UT), and referred to the Committee on Energy and Natural Resources. A hearing was held on September 16, 2026, indicating active committee engagement. The bill amends Section 615 of the Energy Independence and Security Act of 2007 to create a Milestone-Based Geothermal Demonstration Program, which would provide innovative financing (e.g., loans, loan guarantees, or other transactions under DOE authority) to geothermal projects in low-permeability and impermeable reservoirs. The program prioritizes projects in regions with limited or no existing geothermal electricity generation, including on or near Indian lands, and aims to accelerate commercialization and generate public data to de-risk future projects. No specific funding amount is authorized in the bill text; it is an authorization bill that would require a separate appropriations act to receive actual dollars. The companion bill HR8437 has been ordered to be reported in the nature of a substitute by voice vote in the House, signaling some momentum, but the Senate bill remains in committee. The legislative path forward includes markup, floor votes, and potential conference, with no near-term market impact until appropriations are enacted.

Adjusting Certain Delegations Under the Defense Production Act
This proclamation amends Executive Order 13603 to share authority under the Defense Production Act for energy matters between the Secretary of the Interior and the Secretary of Energy, allowing each to act independently, and directs inter-agency dispute resolution via the National Energy Dominance Council and National Security Council, with coordination from the Department of War when national defense is implicated.
Declaring a National Emergency to Secure the United States Bulk-Power System
This executive order declares a national emergency to restrict foreign-produced bulk-power system electric equipment that poses national security risks, prohibiting new transactions involving equipment from covered foreign entities and allowing the Secretary of Energy to impose conditions on existing equipment. It directs the Secretary of Energy, in coordination with multiple agencies, to identify, mitigate, and potentially replace risky equipment, and establishes a pre-qualification list for approved vendors.
Adjusting Imports of Unmanned Aircraft Systems and Unmanned Aircraft Systems Components into the United States
This proclamation imposes a 100% ad valorem tariff on imports of unmanned aircraft systems (UAS) over 25 kg, those with thermal imagers, docking stations, and certain components, and a 25% tariff on UAS under 25 kg and other components, citing national security under Section 232 of the Trade Expansion Act. It also authorizes the Department of Commerce to establish an onshoring program offering preferential tariff treatment for companies that build new U.S. manufacturing facilities for UAS and components.
