"Rooftop solar has continued its massive incursions into the business case for
coal fired power generation over the weekend, smashing all sorts on consecutive
days as it continued to reshape the grid and highlight how more power now now
shifted to the consumer.
The records started tumbling on Saturday when a number of data providers,
including GPE NEMLog2, noted that the share of rooftop solar on the National
Electricity Market reached a record 46.74 per cent at 12.25pm (AEST).
That easily shattered the previous benchmark of 44.26 per cent set nearly a
year ago. Rooftop solar was generating 11,000 MW at the time.
And on Sunday, rooftop solar grabbed an even bigger share, jumping to 47.3 per
cent of the NEM, at the same time sending operational demand to a new record
low of 11,953 MW, according to the Australian Energy Market Operator, beating
the new low of 12,393 MW set just a day earlier.
On both occasions, rooftop solar was eating into the output of coal fired
generators, sending black coal to a record low output, although it was also
causing significant amount of curtailment of large scale wind and solar, due to
the lack of adequate storage.
More than 1.2 GW was being sucked up by pumped hydro and battery storage,
attracted by the wholesale market prices of minus $64/MWh at the time. The
wholesale prices were negative for most of the daylight hours."
