Ann: Pumped Storage Hydro Update - Feasibility Optimisation, page-10

The Feasibility Optimisation announcement is even better than it first sounded.

The announcement mentions "+25%" increase on the previous design output. But going from 6 hours of generation per day to "more than 8 hours" per day for the same rate of power generation is actually a +33% increase on the previous design output.

So anyone revisiting their financial analysis on the better output (and at reduced capex!), should use +33% on the previous base assumption (not +25%).
