A real world analysis of a near-100% renewable grid in Australia - Year 2.

reneweconomy.com.au A near 100pct renewable grid for Australia is feasible and affordable, with just a few hours of storage

Two years of simulations show that very close to 100% renewable electricity is affordable and feasible for Australia’s main grid, using just a few hours of battery storage.

A near 100pct renewable grid for Australia is feasible and affordable, with just a few hours of storage

This is a great article that uses real data to see how our grid world perform with greater wind, solar and storage. It shows that we can easily achieve a 95% renewable grid with a modest level of storage.

What i really like about this, is it has been running for 2 years now, and it is pragmatic about its aims (ie, not 100%), it aims for reality (this is real data that is collected weekly), and it looks at the cost (in $$ and CO2-e).

He sets some targets (60% Wind, 45% Solar + storage), then works off of the actual data to scale the wind & solar generation, to see how it would meet demand. excess is accumulated in storage (theoretical battery storage and actual hydro), and shortfalls is taken from storage.

The really nice part shows where "other" is required, in Australia's case, existing fossil fueled peaker plants.

I often use his 1st year report to have the discussion with "non-believers" to show what is possible, and where the gaps are to achieveing a renewable grid.

Have a read and let me know what you think.
