Turning old mine pits to electricity gold

Miners are meant to rehabilitate old mine sites. An attractive alternative can be to turn them into money-making concerns by means of pumped hydro.

On 27 November Sophie Vorath wrote that the first phase of the Kidston Renewable Energy Hub – a world-first solar and pumped hydroelectricity hybrid – would be generating power for the grid within the next 10 days, which means it started to operate while the votes were being counted in the Queensland election.

There’s more from ARENA, which contributed funding, at Renewable, reliable energy from an old, abandoned mine site? That’s gold Continue reading Turning old mine pits to electricity gold

1. Ballarat and Bendigo targetted for blackouts to keep lights on in NSW

It didn’t happen, but the phone call was made during the early February heatwave:

    Victorian Energy Minister Lily D’Ambrosio confirmed she was approached by the Australian Energy Market Operator (AEMO) with the suggestion that either Ballarat or Bendigo could potentially lose electricity for a period of time to assist NSW.

Victoria was not impressed and have demanded an explanation. Continue reading Climate clippings 199

Snowy hydro 2.0: nation-building game-changer or giant red herring?

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.

Gas, pumped storage and energy futures

Craig Emerson says we can get the gas we need, but is it necessary?

Craig Emerson has an article in the AFR, also on his site, suggesting that politicians need to urgently turn their minds to gas supply in east Australia. Emerson had warned them back in 2014, but they took no notice, and AEMO assured everyone there was no problem.

Suddenly there is. The price of gas-fired electricity threatens manufacturing jobs, and gas is needed to replace coal-fired power. Continue reading Gas, pumped storage and energy futures
