Vistra (VST)
One-line summary: Independent power producer with a nuclear + gas fleet; AWS signed a 1,200 MW net-metering co-location at Vistra's Comanche Peak nuclear plant — a datacenter-power deal in the CEG mold.
What it is
Vistra Corp (NYSE: VST) is a large US independent power producer (IPP) with a generation fleet spanning nuclear, natural gas, and renewables, plus a retail electricity business. Its nuclear assets (including the Comanche Peak plant in Texas) make it a listed play on the reliability premium hyperscalers will pay for baseload power.
Why it matters to stock-market
Vistra is a beneficiary in the ai-capex-to-power-and-materials-cascade and a second listed operator (alongside nuclear-baseload-for-ai-data-centers's primary names) for hyperscaler co-location deals at nuclear sites. The AWS Comanche Peak arrangement is the same structural trade as the Constellation/Microsoft Three Mile Island PPA: a hyperscaler paying for firm, baseload nuclear power adjacent to a datacenter.
Why on the map
- AWS co-location at a Vistra nuclear plant. From 2026-06-25-feed-semianalysis-us-grid-constraints-40gw-behind-the-meter-datacenter: "AWS signed a 1,200 MW net-metering arrangement at Vistra's Comanche Peak nuclear plant."
Open questions
- Regulatory durability of behind-the-meter / net-metering co-location at nuclear sites, given the FERC large-load scrutiny that has dogged similar deals.
