The raw EIA hourly generation data behind every scenario — aggregated so it’s actually readable.

5.7deaths per TWh (central) — this region's recent generation mix

Not a model projection — what this region's grid actually ran on, read as lives. Coal-heavy regions (the Midwest and Plains today) sit highest; renewable- and nuclear-heavy regions lowest. About 94% of it is modeled (air-pollution/radiation) rather than counted accidents. Covers 99% of generation (the rest is “other,” which has no single coefficient). See the risk ladder for the per-source rates.

The band is scientific uncertainty, not rounding. Each source's death rate is a central estimate with a much higher upper bound — coal's depends on how air-pollution exposure is modeled; hydro's high bound includes the 1975 Banqiao dam failure, its central figure excludes it. Reported deaths carry those ranges across the mix, so a mortality figure is a band skewed upward, never a single number. Pricing a death adds a second range (the VSL is itself low/central/high), so any priced-mortality cost inherits both.

Deaths are an accounting attribution to the generating region, not an atmospheric model — real pollution crosses regional boundaries, harming people on both sides of a border. The uncertainty band propagates into any priced-mortality cost, so a priced total is a band, not a single number.

Typical day — capacity factor

Average capacity used (capacity factor), by hour of day, across 6 years.

Weekly average, 20202025

Same data, week by week, showing the seasonal pattern and any year-over-year drift.

Peak capacity by year

The highest hourly output ever recorded for each source, per year — this is what the model treats as that source’s starting capacity.
