Drag a slider to set a source's 2050 endpoint — earlier years follow automatically (changes phase in gradually from 2024). "Adds to total" grows the pie; "Rebalances mix" squeezes the other sources instead.
Click any cell to get a slider for it. Each year has two columns: % edits change the mix and leave the year's total target alone (the source's TWh follows). TWh edits set that source's absolute output — the year's total moves by the difference, every other source keeps its TWh, and all shares recompute (mix stays at 100%). The Total Generation target row scales every source proportionally, which is why it doesn't move the percentages.
Each driver adds (or removes) TWh of final electricity demand by 2050, phasing in from 2024. Hover a row for its basis. All numbers editable.
Required generation (demand × grid multiplier) against what your supply assumptions produce. The dashed red line on the chart is demand.
Your 2050 mix, with the workbook's Benchmarks 2050 comparison when the IEA toggle is on (Δ = percentage-point gap vs IEA NZE).
Mirrors the Outputs sheet (rows 56–65) — these values feed the chart and the Excel export.
Advanced fission verticals per the original workbook: Micro (1–10 MW), Mini (10–50 MW), SMRs (50–500 MW). IEA NZE 2050 benchmark values from the workbook's "Benchmarks 2050" sheet. Endpoint changes phase in on a linear ramp from 2024 to 2050, preserving the shape of the existing path.
