Vogtle is also the most expensive electricity in the world, the only electricity costing more than $10,000 per kW.
Vogtle won't stay the most expensive. My idiotic government (Ontario, Canada) is committing to building a new nuclear plant. $400 billion for 10GW, and that's before the inevitable delays and cost overruns. Maybe we'll break the $100,000 per kW mark!
And on the other end of the spectrum, grand coulee would be ~$1,500/kW in todays dollars.
