Is this the same technology where they use excess power to pump water back into the lake during low grid demands so as to re-coup some energy back when its needed?
from an efficiency standpoint I would like to see some figures, its still costing power to pump the water back up, and would obviously use more energy to do that than what you get back, but if its electricity that would otherwise be wasted, I guess it makes sense, I guess the dollar for dollar investment needs to be taken into consideration on what it would take to make it a financially viable option.
Personally I think we need to diversify our energy needs more and we rely far too heavily on hydro.
What will our energy demands be going forward with the rise of EV's? There will need to be an incentive to charge vehicles during off peak times to balance grid loads, among other things.
El Nino weather patterns favour wind power really well, but they can be utterly useless when there is no wind. Im quite interested to see the potential that tidal power could offer, its a constant energy source that will never be depleted and is there 24/7. So far no one has developed it on such a large scale, but could be a good thing for Kiwis to develop, we have alot of clever people here!
