New activity in the V2G landscape https://www.interest.co.nz/technology/131972/electric-vehicle-batteries-bring-energy-flexibility-opportunities-including

 

 

I am currently of the opinion that "V2G will help balance the grid" is on the same shelf as "Green hyrodgen is great to smooth the grid" 

 

 

 

It only works if you have mandated net metering,  but even then, the efficiencies scale so it is becomes very attractive for commercial grade (GWH+) battery investors to enter to market and totally eat residential installs for breakfast... 

 

 

 

In OZ, the amount of large scale batteries going into the grid is huge, mostly funded by private equity and investment vehicles and they will likely be doing it at finance rates significantly lower than those available to home owners...

I can see this happening in NZ in the near future, likely co located with the industrial scale solar that is currently exploding around the country 

 

A synergy already exists for those that have both 'rooftop' solar and EVs. The advantages gained by one when the other is brought into play are boosted in terms of ROI on both. By adding V2G to that combo it presents the EV with the opportunity to become an income earning asset in its own right by way of 'playing' the electricity market together with the existing benefits of battery storage.

Add to this the reduced cost per kWh of storage capacity that is often presented when EVs are compared to static home batteries, together with their mobility which can be used to 'bring electricity home' when house supply is in short supply and the only hurdles that exist in this space currently are bidirectional EVSE availability and price, V2G enabled EVs and a regulatory platform that allows this form of connectivity.

As the latest 4777 electrical standard is rolled out across Australia and then NZ the popularity of using an EV to power your whole home will become apparent. This level of grid independence is now being discovered by solar owners with 'blackout' enabled battery storage and V2G will allow this resilience to be enjoyed by more consumers by repurposing a 'battery on wheels' that allows them to do so.
