Know how much nuclear is off the grid, what's coming, and what it's worth.
NukeGryd turns the U.S. reactor fleet into a tradable signal: megawatts offline by ISO, a probabilistic forward curve, and what a supply loss means for on-peak price. Built on data nobody else assembles.
National supply curve
Total MW offline by day, back through every season and forward through the next. One continuous availability signal, free.
Probabilistic forward curve
Projected refuels and their MW impact months ahead, as a P10 / P50 / P90 confidence band you can size against, not a single guess. Scheduled dates where utilities publish them, model projection beyond.
ISO / RTO breakdown
PJM, MISO, ERCOT, CAISO, ISO-NE, NYISO, SPP and the non-ISO Southeast and West, every unit attributed to its balancing authority.
Market impact
Nuclear supply set against ISO demand, gas and on-peak price, with a supply-shock backtester and a forward estimate of what an outage is worth in dollars per MWh when the grid is tight.
Outage-risk radar
The units most likely to surprise the market, ranked: model-projected overruns and live forced-outage exposure, rolled up by ISO.
Same-day NRC wire
Scrams, trips and power cuts the moment the NRC posts them, ahead of the next-morning status report, matched to the fleet.
Scenario builder
Slip a start, extend a refuel or drop in a hypothetical trip and re-curve national supply in real time, with the estimated price impact of your what-if.
Weather & fuel context
Heating and cooling degree days and the gas regime explain why a loss bites or gets absorbed, with seasonal normals and an 18-month forecast.
Alerts & watchlists
A morning brief of the supply shifts that matter, by email or Slack / Teams webhook, filtered to the ISOs and units on your watchlist.
API & signal library
Every series, MW offline, ISO splits, prices, degree days and the raw model features, in a keyed JSON API and documented CSVs for your own models.
Give away history. Sell the edge.
The full national curve and today's snapshot are free, forever. The probabilistic forward curve, the ISO breakdowns, the price-impact layer and the scenario builder are where you get ahead of the move, and they unlock the instant you subscribe.
