The Ute Tribe will construct one of the largest solar farms in the US

Original Article ↗ Hacker News Discussion ↗

A planned $1 billion, 756 MW solar farm on the Ute Mountain Ute Reservation is being hailed as a major clean‑energy and economic opportunity for a federally recognized Native American tribe, raising questions about how profits will be shared with members and how the project will be financed and connected to the wider grid. Commenters explain the unique “sovereign yet dependent” legal status of U.S. tribes and how this shapes their ability to host large‑scale energy projects, contrasting the tribe’s move away from fossil fuels with historical underinvestment and exploitation. The project also prompts broader debate over solar’s land, material, and transmission impacts versus nuclear power, as well as ideas for using excess energy for data centers, hydrogen or ammonia production, rather than long‑distance electricity exports.

Project scale, output & economics

  • Article’s “annual capacity 756 MW” is called incorrect; commenters say 756–971 MW is nameplate capacity, with expected annual output ~1,700–2,400 GWh and ~25–30% capacity factor.
  • One estimate: output ≈0.17% of 2022 US electricity consumption.
  • Rough revenue back-of-envelope: at typical US solar PPA prices, tens of millions of dollars per year.
  • Multiple comparisons to an AP1000 nuclear reactor: solar plant gives ~15–20% of a reactor’s delivered energy, but for ~14% (or less) of the capital cost; operating costs for solar are also lower.

Financing & risk for the tribe

  • Several question how a ~$1B project will be financed; expectation is outside capital, not tribal cash.
  • London-based Canigou Group is mentioned as the financial backer, with a track record on smaller renewables and interest in using the power for hydrogen/ammonia production.
  • Some worry the tribe could be locked into a lopsided deal or that benefits will accrue mainly to internal elites or external corporations, as has happened with other resource projects on tribal lands.

Tribal sovereignty & legal context

  • Extensive explanation that federally recognized Native American tribes are “sovereign yet dependent” nations: they have governments, courts, and police, and often enjoy autonomy from state law on reservations, though federal law and Congress ultimately dominate.
  • Status depends heavily on federal recognition and specific treaties; history of broken treaties and erosion of power is emphasized.
  • Commenters stress that many reservations are poor, under-resourced, and must navigate complex, asymmetrical relationships with federal and state governments.

Environmental & land-use concerns

  • Some ask about material and mining impacts for millions of panels; lifecycle analyses are cited suggesting panels repay their embodied energy within a few years.
  • Land-use tradeoffs are debated: solar’s footprint vs coal, nuclear, dams, and climate impacts; desert ecosystems are noted as fragile and not “empty.”
  • Environmental surveys for rare species (cacti, owls, etc.) are described as labor-intensive, on-the-ground work; similar examples from other projects (hamsters, bats).

Solar vs nuclear & grid integration

  • Large subthread debates whether nuclear should be the “real future” versus rapid solar/wind buildout.
  • Pro-renewables arguments: nukes are financially and politically stalled (US AP1000 projects, China’s modest nuclear share); renewables’ LCOE keeps falling; storage (pumped hydro, batteries) plus diversified wind/solar and better transmission likely remains cheaper overall.
  • Pro-nuclear arguments: high solar capacity factors on paper ignore intermittency and storage costs; solar land/ecosystem impacts; nuclear’s 24/7 output and small footprint seen as superior if cost/permits could be solved.
  • Consensus emerges that all low-carbon options are desirable, but practical deployment today strongly favors solar/wind.

Transmission, use of power & alternative loads

  • Project location benefits from existing high-voltage lines from a decommissioned coal plant and regional WECC interties.
  • US-wide, new transmission is described as slow and process-heavy (permitting, studies, lawsuits).
  • Ideas for using power locally: data centers, industrial loads (smelting, lithium refining), hydrogen/ammonia or methanol production.
  • Bitcoin mining is repeatedly proposed as a “stranded power” use and just as strongly criticized as wasteful, environmentally harmful, and politically toxic.

Governance, equity & broader policy

  • Commenters hope for a “sustainable economic boom” but highlight risks of unequal profit distribution within the tribe (“1% problem”) and exploitative contracts.
  • Broader critiques target US utilities that cap distributed solar, policy inertia on transmission, and slow public-works processes, contrasting them with historical fast builds that ignored safety and environment.
