Expiry is the current operating license end date on file with the NRC. A unit marked Original has not yet taken a renewal, which is where a life-extension case gets made; one showing a year has already been extended once and may extend again. License dates are public NRC filings, so this board is verifiable line by line against the docket.

Read this carefully. Net summer capability is restated by EIA most years by a few megawatts, which is measurement rather than metal. Only a step of 1.5% or more is counted in the Uprate steps column; the Added column is the cumulative change since the unit's earliest record and will include some restatement drift. A unit with a large gain and one or two counted steps has genuinely been uprated; a small gain with no steps has not.

Licenses and uprates move over decades. The forward curve is the same fleet at trading horizon: which unit comes off line when, how long for, and how much of that is already priced.
