Records have fallen again across Australia’s main grid in the past few days, with new benchmarks set for renewables share, wind and solar share, coal lows and production records in multiple states.
New records tell an exhilarating story of Australia’s ongoing renewable energy transition, but also point to some shortcomings, with record levels of forced downsizing of wind and solar power in South Australia talking about the investment required in storage, load management and new. Technologies such as green hydrogen.
Saturday was the scene of multiple records, as the share of renewables in the national electricity market, the main grid that includes all states except Western Australia, jumped to 64.34 per cent at 10.45 am on Saturday, improving the 62.94 per cent level that reached to only two. A few days ago.
On Sunday, those records were again smashed, as the share of renewables jumped to 64.6 percent.
Other records set by GPE Nemlog2 data analysts include the share of wind and solar (i.e. not including hydro), which reached a new peak of 61.84 percent at 12.05 p.m., surpassing the previous peak of 60.95 percent set on November 11 of the year Past. Winds alone set a new record high of 35.92 percent early Sunday morning.
The corollary to these new standards were record declines for coal (down to 34.16 percent, from 36.31 percent the day before, highlighting the scale of the new records) and fossil fuels (coal and gas), which fell to 35.59 percent.
There were new record lows for the production of coal, coal and gas, which fell below 9,000 MW for the first time to record a new low of 8,965 MW, much lower than the previous low of 9,245 MW in October last year.
The new records are an inevitable result of good sun and wind conditions, and the number of additions to the network of large-scale wind and solar farms over the past year, not to mention rooftop solar.
The maximum share of wind and solar in the main grid is still below the average share of wind and solar in South Australia – which leads the world in adopting “variable renewables” with an average share of more than 64 per cent last year.
But a day after The country has set a new immediate share of renewable energy sources at 146 percent – When it was able to export a third of its production to Victoria – a record level of curtailment came, when the country was unable to export much of the excess capacity and domestic demand was low.
According to GPE NemLog2, wind and solar power cuts reached a record 1,445 MW at 1 pm on Friday, well above the previous high of 1,351 MW in late August.
This graph shows that demand was relatively low, and rooftop solar was absorbing a lot of that. Exports to Victoria have been reduced, probably because that state was well served by its own renewables, which hit a new high of 84 per cent earlier that morning, and also because of grid restrictions.
As the amount of wind and solar increases, and the average share of renewables also rises to nearly 100 per cent of domestic demand in South Australia, it points to a growing need for storage in the state, and opportunities for green hydrogen and “other loads” could absorb that capacity. excess.
