Australia: Electricity prices across the grid fall to ZERO as renewables reach 44% share

22 July 2019 |

You don’t get to see this very often – when the spot price of electricity on all the state-based grids in Australia’s main wholesale market hit zero at the very same time.

The incident, captured in this screen shot of the Australian Energy Market Operator’s data page by Macquarie Capital’s Brian Morris and posted on his LinkedIn account occurred at 1.15pm on Sunday.

This was when cloudless skies and good breezes – and low demand – pushed the share of renewables to more than 43 per cent. At the time of the zero pricing, wind was providing 12.3 per cent, while the combination of rooftop solar and utility-scale solar was providing 22.5 per cent.

About half an hour earlier, the total output from renewable energy was 9931.64MW , well ahead of total black coal 9014.85MW and nearly three times the output of brown coal 3426.06MW, although this is not the first time renewables have nudged out black coal – it did it in April....

But over the past 48 hours, South Australia and Victoria have experienced negative prices due to the big amounts of wind generation (in the early hours of the morning), and due to the combination of high wind output and strong solar output during the middle of the day. more:

Attention DI Hydrogen Scholars:

Do YOU Think (...) that, in the future, there will be MORE Excess renewable energy


LESS EXCESS renewable energy?

That country hasn't even BEGUN to utilize solar and wind and the prices are ZERO sometimes NOW
