Honestly, if I’m not getting paid to put zero carbon electricity in the car on Sunday morning there will be a stern letter to the management. Look how those isobars are packed.

@Mark Koek Depends on the system. I have a Moixa inverter controller which automagically charges batteries when electricity is cheap and sells electricity to the grid when it’s expensive. (Or switches rapidly between buying from the grid and selling back when export prices are greater than import prices)

@ajlanes @mkoek With Octopus there is a tariff available for EV owners whose car or smart charger is able to integrate with their system and vary charging across thousands of cars to vary the load for the grid. In my case I use weather apps for medium scale forecasting and then make plans with the day ahead Agile tariff. If I can get a negative price I plug the car in before bed and set the timer manually to draw the amount I can put in the battery at 6.4kW.

@ajlanes @mkoek For instance, in this case I’ve got room for about 20kWh to top the battery off at just over 80%. I can set the timer to allow charging to start at 2am and finish at 5am. Those three hours at 6.4kWh will give me 19.2kWh but I’m only going to do it if the price is negative.

@GlasWolf Some industries will start their Christmas shutdown this weekend so I’m assuming that the overnight load will be even lower than usual for a Sunday. Factor the likelihood of a record wind generation and I think the grid will want to encourage flexible loads to connect and have a free buffet.
