Ann: 50MW Solar Project Revenue Update, page-5

The Genex corporate presentation shows that the proposed site has higher wind during night hours, so would complement the Solar. Thus wind power could be sold into the market during the evening peak alongside the Pumped Hydro, as well as being able to either feed into the grid or be used to replenish the PHES at other times.

The continued increase in both domestic and large-scale solar generation capacity could easily result in the duck curve where it can supply the majority of power required by the grid, leading to low or even negative grid power prices for generators. Genex will have the advantage of being able to use its solar (and later wind) generation for replenishing the PHES storage during these periods of excess supply and low prices, and sell the power later when prices are high.
