ILLUSTRATIVE OUTPUT

2.365 TWh

annual electricity generation

Total installed capacity300 MW
Average output over the year270 MW
Annual demand2.190 TWh
Annual energy coverage ratio108.0%

Annual energy exceeds the demand assumption by 0.175 TWh.

Annual energy coverage does not measure continuous supply. Outages, reserve margins, grid constraints and hourly matching are excluded.

Every number has an explanation.

Installed MW = units × MW per unit.
Annual MWh = installed MW × 8,760 × capacity factor ÷ 100.
Annual demand MWh = constant demand MW × 8,760.
Coverage ratio = annual generation ÷ annual demand × 100.

A non-leap year is assumed. Inputs are generic and do not describe a specific reactor product. This tool does not model capital costs, electricity prices, licensing, construction dates, heat output or an engineering feasibility assessment.
