“Moving beyond baseload:” NSW turns to consumers and local storage to fill Eraring gap
NSW announces $1.8 billion, including a new focus on consumer energy resources, such as neighbourhood batteries, in its Energy Security Corp.
The New South Wales Labor government has confirmed it will turn to consumers and local and shared storage as part of its plans to spend $1.8 billion to fast track its response to the proposed closure of the country’s biggest coal generator in two years time.
The Minns Government on Wednesday outlined a $1.8 billion “boost” to help “rescue NSW’s energy transition”, and fill the gap that will be created by Origin Energy’s planned closure of the 2.88GW Eraring coal facility in August, 2025.
The Australian Energy Market Operator has said that if government tenders for nearly a gigawatt of “firm power” and other renewable and storage projects are delivered on time, then there should be no breach of the country’s tight reliability standards.
But NSW – fearing delays in project delivery and commissioning – has decided to fast-track other measures that could boost the capacity and reliability of the grid over the short term.
The $1.8 billion package – announced at the site of a new community battery at Blacktown in western Sydney – includes a previously announced $1 billion to establish the Energy Security Corporation.
This was largely seen as a vehicle to support pumped hydro storage, which hasn’t been able to compete with batteries even when the guidelines require eight-hour storage.

@Wiggles if they are going to rely on consumer storage, the state governments of Australia should really pull their fingers out with V2G technology. An EV typically has at least 3x the storage of a fixed home battery, 60kWH vs 20kWH. So if they really want consumer storage to work, it needs to be accessible. At the moment South Australia is the only state where V2G technology is certified for connecting to the grid. #V2G
Yeah I agree V2G will play apart in complete electrification of the grid, but I think other community or residential energy storage will be necessary too as EVs aren't guaranteed to be connected to the grid during peak solar generation times. They will be good for supply during peak demand times though, especially as demand peaks when everyone gets home from work, at which time they will be grid connected and can discharge when necessary, with the EV the recharging overnight while energy is cheaper.
The only way I can think of making them a primary storage source is if absolutely every car park in the country has an V2G EV charger installed. That way the online time they would be disconnected I when they were in use. The complication I can see with this though is its hard to predict user habits so if the batteries discharge to the grid too much then the user will be limited to travelling shorter distances. A way around that would be to allow a maximum discharge amount be set I the EV, but this could lead to everyone setting it very high to limited energy is made available to the grid anyway.
@Wiggles Australian electricity use in 2020 was 265,232 GWH for the year. That's 726 GWh / day. If we take 12 h of daylight, during which time solar generation is providing power, (and recharging batteries), we can say we need 1/2 the daily amount for overnight storage, or 363 GWH.
If we say each ev has 60kWH of storage, that means we need 6050 cars, or 18150 cars if we only use 1/3 of the battery charge.
There are 20,000,000 cars in Australia (20 million). That's enough to cater for Australian daily energy storage needs 1100 times over, assuming a conservative 1/3 of the stored energy capacity is used.
So I dispute your conclusion that here has to be v2g charging points every where.
As per the above, if only 1 in 1100 cars (<0.1%) had a V2G connection at home, that would provide enough for Australian energy storage self sufficiency
Its a fucking no brainer. So why is south Australia the only state that allows V2G connections to the grid?
