The NEM 1 year rolling average has hit 40.0% renewable energy.

NEM 1 year AV still under 40% Renewables, at 39.8%.
Been close to 40% for soooo long but a tough number to get past.
Must be time to start a poll on the date it will reach 40%?

Hey @nicknet.bsky.social look at the proposed new Vic minimum fed in tariff starting 1 July.
Dropping from 3.3c/kWh to 0.04c/kWh.

Houses in Australia typically have 2 or 3 or 4 Power(point) (not light) circuits, and there are typically a dozen single or double GPO outlets on each circuit.
My house has 3 circuits & 34 (mostly double) GPO outlets.

They have been putting some 400V 3 phase A.B.C. along the street under the 22kV.

this is stunning, the annual demand for South Australia Residential.
due to rooftop PV the Residual Operational Demand for Residential (compared to Business/Industry) is so small you might have trouble seeing the wedge in the chart.
i did not realise how tiny the SA Residential residual demand was.

the definite area of grid enhancement needed though is for business and industry, with a possible 2050 residual operational demand doubling from 136TWh/y now to ~280TWh/y in 2050.

yes, although some surprises, ex' the ISP suggests Residential residual operational demand in 2050 of 50TWh/yr, not much more than it is now in 2024.
BUT it might be much more variable, with deeper troughs, higher peaks? (Not tried to extract that dataset.)

indeed, it is very cheap, but likely below normal factory gate real prices as this nice waterfall chart suggests.
but is certainly suggesting there is a lot of storage manufacturing capacity out there.

yes, the challenge going fwd is to make sure that the growth of pv is matched by the growth of MV (dnsp) storage and the growth of LV PV, storage and EV demand.
working on that the DNSPs are doing some serious (800 billion data point) fwd forcasting modelling to match DNSP data to AEMO ISP data.

and if you look at the last 12 months the utility grid VIC PV AV (Spot before hedges) was 2.84c/kWh.
so very close to the VIC FiT of 3.3c/kWh.
possibly even closer after hedges included?

No, as you will see here most scenarios have lower rooftop pv to grid pv ratio compared to the isp.
Except for the REF Scenario, so that is worth some discussion.

the resulting A$230Bn to $335Bn investment in the Distribution network calculated in #NZAu is one of the reasons i despair at people who keep using the ISP for these discussions.

most DNSP RABs go up about 80% but with much greater volume of power being delivered (i.e. 3 times) the DNSP cost per kWh stays pretty much the same per kWh, i.e. in the range 8 to 12c/kWh.
