Also, there have been a *lot* of problems with Francis turbines of late: https://phys.org/news/2015-05-hydropower-turbine-failure.html

Your points are well made.

With 20 turbines, the it seems to me the probability of total turbine failure seems unlikely. I can visualize a turbine problem that developed a control situation that the inexperienced and incompetent staff could not handle. Efforts to solve the problem made at gunpoint exacerbated the problems to the point of unresolvability by other parties than the manufacturer.

We can now encourage further speculative and informed discussion
