Nuclear Output Trends
What the fleet is producing, against the last 30 days and against the same date last year. The two
comparisons carry the season, so a refuelling dip reads as a dip and not as a crisis.

Right now is the grid operator's own published fuel mix, shown only when the reading is under three
hours old. Latest day is EIA's metered total for the most recent complete day, which runs a day or
two behind. The vertically integrated Southeast and West publish no fuel mix of their own and are not in this table;
their units are on the market hub.
This is where output is. The forward curve is where it is going

Every unit's next outage, sourced where an operator has filed it and projected where nobody has, rolled into one probabilistic curve.
