  1. CW: NZ - Lake Onslow battery back on again?

    The Lake Onslow pumped storage project which the Luxon government killed in 2023 may be back on the cards. A consortium led by former Meridian CEO Dr. Keith Turner has had the project accepted for the fast-track process.

    Remember the scary costs which were bandied about before National canned the project? Turner says the MBIE estimated costs ballooned because they included items such as life-time operation costs and life-time financing costs.

    "The costings have been pretty widely represented in the public arena as sort of $15b-$17b, but those numbers are not correct. If you go to the MBIE project files, the capital cost of the project is somewhere between $8.5b and $10b, depending on how big a bottom pond you have. Those $15b to $17b numbers were not the capital cost at all."

  6. Is there life left in the Lake Onslow project? While Luxon's lot kiboshed the scheme, a private consortium is sniffing about and seeking investor interest.

    The property owner, Richard Hore of Beaumont Station, says "Hopefully, the new fast-track legislation would help get any proposed project under way quickly."

    Fast track... the developer's magic salve for those pesky environmental concerns.

  9. Forget nuclear, Australia is on fast lane to 100pc renewables
    michaelwest.com.au/forget-nucl

    Australia's politicians have argued over renewables for decades. Some are wasting time on purpose and hyping nuclear power to keep us using fossil fuel.

    Meanwhile, citizens and private industry have led the way with solar power. Australia is well on the way to 100% renewable energy — sooner than many people realise.

  10. Last week I attended an event by @klimatriksdagen on #energytransition - it was interesting and educational!
    My key takeaways:
    1: #windpower has decreased in price by 63% since 2009. #nuclear power, has increased in price by 49%! 😮
    2: Politics should remove fossil fuel #subsidies and invest in #energyefficiency !
    3: Phase out #plastics from waste to reduce district heating #emissions
    4: Secure a #sustainable #energy supply. Invest in #pumpedhydro & promote local #energycommunities 🌞🌬

Snowy 2.0 Pumped Hydro Project making progress despite budget ballooning sixfold to $12bn and a delay of supplying power to the grid by 7 years (2028) Six turbines about to be installed more than 1km underground to generate 2,200MW for a total of 350GW-hours – enough to power 3m homes for a week.

  16. Queensland's 250MW/2,000MWh Kidston pumped hydro project remains on track to be powered up in the second half of 2024. Due to a water ingress event, the company realigned the tunnel away from the zone of fracture, adding extra cost, longer tunnelling.

    If only the 2.2GW Snowy 2 Pumped Hydro project had done much more geotechnical surveys....

  17. This ABC doco is recommended for those interested in large tunnelling projects and Australia's Snowy Hydro 'pumped hydro' battery that is running years late and hugely over budget.

    The tunnelling machine is bogged.

    I read the EIS in detail back in the day, advising on groundwater as part of a larger submission.

    I am confident that the geology ahead is poorly mapped and complex. Weathered basalt and limestone are both possible, with more opportunities for bogging and flooding. Watch this space...

  22. Snowy 2.0 #PumpedHydro cost blow out to an estimated A$20 billion ... perhaps the wrong renewables decision by Turnbull back in 2017? But because of sunk cost, Labor are continuing with the project despite batteries and solar on warehouse roofs being a cheaper and scaleablelocal option.

  23. @glennn

    We should be building Pumped Hydro everywhere (not the disastrous Snowy 2.0 though)

    “Pumped hydro storage is the ideal complement to wind and solar electricity generation: versatile, modest in scale, cost and build-time, little environmental disruption, mature component technologies, few toxic chemicals, durable. Yet it is consistently overlooked in mainstream discussion in favour of gas-fired power stations, batteries and the nuclear zombie. It is also shackled by out-of-date regulations, short-sighted financial criteria and the business models of privatised entities.”

  24. CW: renewable future; ableism in video title

    Would still love to see some exploration of potentialities for hybrid pumped-hydro storage / inland solar desalination projects.

    Even without such, still impressive what futures can be imagined (problematic language for video notwithstanding) when we actually collect and analyze some data.

  25. "The resource assessment for larger, grid-scale projects showed the potential for more than 1,800 closed-loop systems in Alaska, with a total energy storage capacity of about 4 terawatt hours (TWh). Because of their small reservoir sizes and dam heights, many locations were identified as potentially suitable for small-scale PSH systems. Nearly 50% of the identified potentially suitable small-scale PSH sites are in Southeast Alaska."

  26. I am about to move to a place with a 180m hill (nearly cliff) next door to it.
    If I put a water tank at the top, and my neighbour puts a water tank at the bottom, can we use the hill as a battery?
    How big is the smallest #PumpedHydro setup that makes any sense?

  27. Once up a time, Lake Onslow was called Dismal Swamp. In 1890 they dammed the Teviot River which feeds it and built a dam. In 1982 a new dam raised the water level by another 5m.

    The government is continuing down the path of pumped hydro despite its estimated $16b price tag.

    Is it a good idea? Are there workable alternatives? Because $16b would buy a lot of wind & solar, reducing the overall load on the grid.

  28. @osma Depth 1400 m (YLE didn't find this worth mentioning). Actually with our bedrock, pumped-hydro installations could be built pretty much anywhere. Using a pre-existing mine saves some excavation work, which is inexpensive anyway using explosives.

  29. CW: Lake Onslow Pumped Hydro

    Took a drive into Lake Onslow out of interest. It lies inland of Roxburgh. Investigation is underway to explore enlarging for storage for pumped hydro. Initial est cost $4b.
    The various tunnel options could support up to 1500MW, with up to six turbines/pumps of 250MW each. For comparison, New Zealand’s largest hydro plant is Lake Manapouri, with installed capacity of 850MW. Huntly power station (coal) has a total installed capacity of 953MW."
