119-HR-5638 DC Insider Whip Count Analysis

Where H.R. 5638 stands

- Scope: technical amendment to the Geothermal Steam Act to assess royalties per electric generating facility and tie the reduced‑rate window to each facility’s in‑service date. [2]Congress.gov — Text - H.R.5638 - 119th Congress (2025-2026): Geothermal Royalty…

- Committee path: considered in a Full Committee markup on Mar. 5, 2026; Natural Resources Democrats characterized a bipartisan geothermal package advanced that day by unanimous consent. [1]House Committee on Natural Resources — Full Committee Markup (Mar. 5, 2026) — H…

- Current status: reported from committee on May 20, 2026; third‑party trackers show it on the Union Calendar (No. 575) with House Report 119‑661. (Congress.gov’s status page may lag.) [3]Quiver Quantitative — H.R. 5638 summary and actions (incl. Union Calendar No. 5…

- Sponsor posture: Rep. Mike Kennedy (R‑UT) is publicly pushing the bill as a fairness/clarity fix; Rep. Nick Begich (R‑AK) is listed as a cosponsor. [4]Office of Rep. Mike Kennedy — Rep. Mike Kennedy press release: advancing Geothe…

Breakdown: expected caucus support

Anchored to verified control and committee signals; no fabricated whip numbers.

• House Republicans: Likely strong support. GOP controls the chamber (217 R, 212 D, 1 I; 5 vacancies as of May 20) and the committee of jurisdiction, whose chair is moving a geothermal/permitting agenda. The bill originated from a Republican sponsor, advanced in the chair’s bipartisan package, and faces little ideological friction inside the conference. [5]House Radio‑Television Gallery (house.gov) — House party breakdown (updated May…
• House Democrats: Meaningful but not universal crossover. Committee Democrats touted a six‑bill geothermal package moved by unanimous consent, signaling openness to “common‑sense royalty reforms,” especially from Western members with in‑state geothermal. Expect pro‑geothermal Ds (e.g., CA/NV/NM/CO delegation members) to vote aye if the floor text matches the reported compromise. [6]Office of Rep. Jared Huffman — Natural Resources Democrats: geothermal package…
• Senate Republicans: Favorable environment. GOP holds the majority and the ENR gavel (Sen. Mike Lee, UT). Western Rs (e.g., Murkowski, Risch, Daines) routinely back geothermal/permitting streamlining; none of the public materials suggest a royalty‑reform red line here. [7]U.S. Senate — U.S. Senate Party Division — 119th Congress (Republicans 53)
• Senate Democrats/Independents: A workable coalition exists. Pro‑geothermal Democrats (Heinrich, Cortez Masto, Hickenlooper) have recently introduced or backed geothermal packages; their posture reduces the risk of a partisan blockade if text stays narrow/technical. [8]heinrich.senate.gov

Key legislators and swing nodes

Members with procedural leverage or outsized constituency interest.

• House: Chairman Bruce Westerman (R‑AR) — controls committee agenda; his shop is actively advancing geothermal items. Floor strategy will key off his and the Majority Leader’s bundling decisions. [9]House Committee on Natural Resources — Chairman Bruce Westerman — committee page
• House: Rep. Mike Kennedy (R‑UT) — sponsor; aligned with the committee’s geothermal push and amplifying the bill publicly. [4]Office of Rep. Mike Kennedy — Rep. Mike Kennedy press release: advancing Geothe…
• House: Rep. Nick Begich (R‑AK) — cosponsor and EMR vice chair; Alaska has strong geothermal potential and Begich has portfolio turf to advocate during floor/manager’s amendment talks. [10]Congress.gov — H.R. 5638 all‑info (sponsor/cosponsor; hearings)
• House leadership: Speaker Mike Johnson (R‑LA) — narrow majority means he must either run this under suspension (if sufficiently bipartisan) or a structured rule; his shop’s bandwidth and competing floor priorities can delay timing. [11]House.gov — House leadership page (Speaker Mike Johnson)
• Senate: Sen. Mike Lee (R‑UT), ENR Chair — gatekeeper for hearings/markups; alignment with a Utah House sponsor is an intangible tailwind for quick processing. [12]U.S. Senate Committee on Energy & Natural Resources — ENR leadership and subcom…
• Senate: Sen. Martin Heinrich (D‑NM), ENR Ranking — long‑standing pro‑geothermal posture; a Democratic co‑sign dramatically eases hotline clearance. [8]heinrich.senate.gov
• Senate: Sens. Catherine Cortez Masto (D‑NV) and Lisa Murkowski (R‑AK) — active on bipartisan geothermal R&D/streamlining; likely yeses if scope stays technical. [13]Office of Sen. Lisa Murkowski — Cortez Masto & Murkowski unveil bipartisan Next…
• Senate: Sen. John Hickenlooper (D‑CO) — fresh bipartisan geothermal bill; another likely yes and potential messenger for floor UC. [14]Office of Sen. John Hickenlooper — Hickenlooper–Daines bipartisan bill to unloc…

Leadership influence and procedural map

- Chamber control: Republicans hold the House (narrow; fluid due to vacancies/independents) and the Senate (53–47); the White House is Republican. That favors floor time and conferencing if needed. [5]House Radio‑Television Gallery (house.gov) — House party breakdown (updated May…

- House path: With a bipartisan committee record, leadership can move H.R. 5638 via suspension (two‑thirds) if text remains non‑controversial, or slot it into a structured rule alongside the other geothermal bills already moving. Recent GOP press from the committee underscores an active floor pipeline for geothermal. [15]House Committee on Natural Resources — Committee press: bills to unleash resour…

- Senate path: ENR can discharge it clean or package it with related geothermal measures. Given broad interest in geothermal across both parties, passage may come by unanimous consent after hotline — unless a member demands amendments or raises scoring/precedent concerns on royalties. Chair/Ranking announcements and recent caucus messaging confirm ENR leadership (Lee/Heinrich) and their energy agenda focus. [12]U.S. Senate Committee on Energy & Natural Resources — ENR leadership and subcom…

Stakeholders and external signals

• Industry: Geothermal Rising filed supportive testimony on royalty clarification and broader geothermal items during the Dec. 16, 2025 hearing/record — signaling organized industry backing. [16]U.S. House Committee Repository — Written submission — Geothermal Rising (heari…
• Western developers/utilities: Active pro‑geothermal posture (e.g., NV delegation activity; multiple developers expanding). These aren’t formal endorsements of H.R. 5638 but indicate a favorable climate for narrow geothermal reforms. [13]Office of Sen. Lisa Murkowski — Cortez Masto & Murkowski unveil bipartisan Next…
