Snowy Hydro 2.0 was, I thought, being justified at the political level by its capacity to back up with pumped storage some of the “reckless” development of wind and solar energy around the place. RenewEconomy now reports that Snowy Hydro is itself planning to develop 800 MW of wind and solar capacity. It has put out an expression of interest document, aiming to conclude contracts by September:
“The initial aim is to procure 400MW of wind and 400MW of solar off takes,” the document states, although the company may change its mind on the 50/50 split between wind and solar depending on the offers made.
“Snowy Hydro’s goal is to construct a portfolio of wind and solar offtakes such that the resulting portfolio benefits from diversification of fuel sources (wind / sun), geography (across NEM States, latitude and longitude) and supply profile (intra-day, week, month and season).”
Can’t do without it, that’s what he said. To impress us he said:
With only 2 per cent of construction visible above ground, the scheme involved 16 major dams, seven power stations, a pumping station and 225 kilometres of tunnels, pipelines and aqueducts.
Just after we had heard about 100 MW batteries being installed in South Australia to keep the lights on, Malcolm Turnbull announced a giant ‘battery’ in the form of pumped hydro in an expansion of the Snowy hydro scheme.
“In one hour it could produce 20 times the 100MW per hour expected from the battery proposed by the South Australian government, but would deliver it constantly for almost a week, or 350,000 MWh over seven days.
Michelle Grattan reports that the media were dragged up to Talbingo in the Snowy Mountains for Thursday’s big Hydro announcement. But then his press conference couldn’t be beamed direct because there was no way of transmitting the signal.
Meanwhile the news cycle was taken up with the pictures of the extraordinary biffo between South Australian Premier Jay Weatherill and federal Energy Minister Josh Frydenberg when they appeared together in Adelaide.
It was all a metaphor for the shambolic national energy debate, in which the process is chaotic and politics trumps policy.
