There is an ever increasing need for extreme flexibility within the power grid both regionally and nationally within a country or countries.  Hydropower generation is and should be a major contributor to this flexibility and strategies are discussed here. Generation flexibility tools discussed, along with a focus on new models that could be adapted to a specific power grid.
