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: 100% RE Last 188 weeks: 98.7% RE (1/5) - ThreadSky

Awesome! ⚡

Last week had:
- average demand (100% of long-term average)
- very above average wind (136%)
- well below average solar (74%) (2/5)

Here is the simulation from weeks 185 to 188. It was 99.6% renewable (3/5)

My simulation has used wind, rooftop & utility solar data from
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)

The following article contains many more details, assumptions & FAQs about my simulation, including what is ‘Other’, estimates of cost ($107/MWh), emissions, required capacity, scale factors, analysis of the most challenging days & much more (end)
