If you happen to have a 40-100kWh battery parked 95% of the time in a single place – what else do you think could be done with it? Well for one – you could be a small piece of the 12 hours of storage our future power grid composed of wind+solar will need. Or you can offer you car to offset your electricity usage when you get home from work – this is especially valuable in high solar areas to the power grid to counter the ‘duck curve.’
Or maybe the only thing you want your car doing is charging and protecting against black outs. Fine – vehicle to grid (or house) helps with that also.
From Ovoenergy.com:
If you exported energy to the grid from your vehicle every weekday between 4pm and 7pm, over a year, you could earn £274 (based on exporting power at 5.7kW, for 3 hours, at a net export price of 7p per kWh).
We estimate that the average annual cost of powering a Nissan LEAF would be £266.61 based on the following assumptions:
- Average annual mileage for a private vehicle: 7,500 miles. (Source)
- Nissan LEAF’s consumption of 4.2miles per kWh
- Unit price of 14.93p per kWh (being the price for an OVO customer on our Simpler Plan excluding regions 17 & 18 where the charger in unavailable)
(7500/4.2) x 0.1493 = £266.61
Therefore, using this example, the estimated average annual costs of £266.61 would be covered by the estimated export credits of £274.
