Thread: Each week I run a simulation of Australia’s main electricity grid using rescaled generation data to show that it can get very close to 100% renewable electricity with 24GW/120GWh of storage (5 hrs at av demand)
Results:
Last week: 98.3% RE
Last 194 weeks: 98.7% RE (1/5)

Every year around April the RE contribution comes down as solar generation reduces just due to shorter days leading up to winter. Probably best shown in this chart.
- below average demand (97% of long-term average)
- well below average wind (81%)
- well below average solar (81%) (2/5)
OpenNEM, rescaled to supply ~60%, 25% & 20% respectively over the year. It uses the storage & existing hydro to match demand. If there remains a shortfall then the model supplements generation with ‘Other’ (4/5)
