Dunno. I guess the company will release more information as their plans firm up, especially if they plan to raise any money from shareholders.

They should be able to sell Pumped Hydro power at a much higher price than Stage 1 since it is designed to generate during peak periods when demand is higher. On the other hand capital costs per MWh will be greater due to the cost of constructing the Pumped Hydro (dams tunnels & turbines). As for the new 270 KWh solar farm, it isn't clear how much of the capacity will be required for priming the Pumped Hydro (i.e, will there be any left over to sell to the market as-is like Stage 1). There may also be some arbitrage possibilities here - they may be able to sell Stage 2 solar power at a higher price during the day than wind or coal-generated power they can purchase at night to refill the upper reservoir.
