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

Even just putting a 240V 2kW charger on an off peak meter (like hot water cylinders use) and only using it for load shedding would probably cover most of the storage needed. 16kWh/day is overkill for most driving profiles, then the only issue is convincing whoever owns the carpark to install/rent an outlet.

I think that we need something like that. I expect that someone will set up a virtual power plant as a way of managing the service and capacity. Either that or it just becomes a ‘must have’ through legislation.
I would like to see the requirement for any new built house to have solar and some amount of storage as a requirement. It just seems to make sense!

Australia’s solar market is un-price-gougey enough and electricity costs enough that I don’t think anyone would really consider not putting solar on a new build with a battery ready inverter. An investment that yields 50% return in the first year is a no brainer.
Virtual power plants seem a bit too silicon-valley. I don’t see anything wrong with a bounded variable time of use/feed-in tarriff (ie. Electricity will cost at least x, at most y, time-average z over the year, you get 30% of retail for feed-in and the prices are published day ahead). Let people own their own charger, inverter, and battery and decide for themselves what thresholds are for the controller (or opt into software).

(VPPs) Yep, but i guess if it doesnt work, we may need something different? VPPs can take advantage of wholesale swings in cost to better leverage the market. Maybe that is how a business is encouraged to put in charging capabilities (capex), they become part of a VPP, that will soak solar during the day. (jots idea down in my tech-bro notebook)
