Pumped hydro energy storage cost model


The great majority of global installed electricity storage for grids is pumped hydro energy storage. This technology is mature, and so costs are more certain. We have teamed up with experienced engineers to produce a cost model that, given some basic information for a possible pumped hydro site, will produce a reasonable cost estimate.
