We all know how often big projects end up costing much, much more than the original plans. But how much more?
This toot from Kees van der Leun references a study which has actually measured this. Fascinating.
Average cost overrun for new power plants:
Nuclear 120%
Hydro dams 75%
Fossil 16%
Wind 13%
Solar 1%
The table is from p. 192 in How Big Things Get Done.-done-book

Nuclear reactors usually end up costing 2 to 3 times as much as they were supposed to, rail projects 1.4 to twice as much, and so it goes. the book looks really interesting.
