South Australia Hits 33% Renewal Energy Target 6 Years Early

ferrisoxide.com writes: South Australia has hit its target of 33% renewable energy by 2020, 6 years earlier than expected, delivering clean power to the state through investment in wind, solar and geothermal energy — mothballing one coal-fired power station in the process. Not content to rest on their laurels, the SA government has now announced a new "stretch" target of 50% by 2025. South Australian Premier Jay Weatherill declared that despite initial upfront costs to renewable energy generators such as wind farms, the 50 per cent target will not add one extra dollar to energy prices.

  1. Works particularly well in SA/Victoria by Anonymous Coward · · Score: 5, Interesting

    The nice thing about wind plus solar in southern Australia is that peak electricity usage is on hot days in the summer. These are often windy as well as sunny.

    That said, this 33% is for South Australia (pop ~ 1.3 mil) which has a much smaller demand than Victoria (pop ~ 6 mil) with well connected grids. So excess power from SA can be readily exported to Victoria.

    As renewable engery use in Victoria increases it will likely be harder to shift excess production. The Victoria/SA market may well face the problem Germany has when wholesale electricty prices drop down to zero. We really need large scale grid storage to get a global SA/Vic production up about 30% from renewables.

      Large scale grid storage doesn't exist in a cheap and efficient manner. That's one of the core problems with wind and solar. It's great for shaving off peak demand but after a certain point it will be investments into useless overcapacity(it's also a great way to make renewables competitive with grid prices though as grid inefficiency costs are offloaded to end users)

      That's what hydro dams are for. They already use them as "batteries" for coal plants because the demand curve of a city is not flat like the output curve of a coal plant. The buffer provided by the dam doesn't stop working just because you swap out the coal plant for a solar/wind farm.

      Lets not even talk about that fact that SA has seen overall demand drop significantly due to the failure of several large industries, with no indication they will return. So, from that perspective, the goals got a lot easier to attain. Of course political speak, by its nature, always sounds good. "will not add a dollar to energy prices", but of course, we also won't talk about the actual costs and how they are paid.

      Overall, they have been able to use primarily wind to achieve what they have. While they've spent a lot on solar as well, its still a small and somewhat irrelevant piece of the pie. It appears the Aussies have figured out that emphasis on wind makes much more sense.

      Per TFA, the have added power supplies to maintain voltage when grid voltage dips. This, however, raises two issues with wind and or solar :

      1. It's an added hidden cost of power. Sure, the electricity prices may not go up but the cost of power doesn't to customers Ast THFA pointed outré, sat some point companies look to other locations without such problems.

      2. Right now, consumers and most businesses aren't seeing a problem because most appliances can handle short voltage drops. However, as the percentage of those sources increase we could see dips that damage appliances or cause consumer or business issues. Expecting them to buy power conditioning equipment isn't a solution that most politicians probably want to suggest, so the producers and or grid companies will have to solve the problem,; whereupon the costs of power will go up as it reflects the actual costs of delivering clean power.

      None of these problems are unsolvable but tend to get ignored in the debate. The regulator in Germany already punted the issue by planning "to discuss the problem with experts and associations in detail" which translated to non-politik sprache means "ignore the problem by studying it." Maybe what's needed is for voting machines to experience problems, that cost someone an election, later traced to a power fluctuation. That sort of cost gets a lot of attention from politicians.
