At the market indicator. 12,500 tU/yr of nameplate capacity, valued at US$ 65.00 per kgU spot, comes to roughly US$ 813 million a year, or US$ 694 million at the long-term indicator. Treat both as scale, not revenue: most volume moves under contracts signed years earlier at prices neither figure reflects, and nothing here is netted against the cost of producing it. The indicators, and forty years of history behind them, are on fuel market prices.
