Today I was looking at my OVO account and getting cross with the incorrect data it showed for my predicted mo mthly payment and the associated graphs, suggesting I need to pay nearly £190 per month…. so I have made my own graphs which are accurate…. I thought people might be interested to see...
I have been in the V2G scheme now for 19 months and after sorting a number of issues with the smart meter (which meant I initially had little or no accurate data), I have just analysed the last 12 bills…. all of which were accurate.
FYI…. We live in a 400 year old 4 bed cottage which has been made as eco friendly as is reasonable without upsetting its character or destroying anything important… (so far efficient house!) however, we have a first generation 1.2Kw PV installation on the garage roof and solar water heaters on the kitchen extension. Because of lockdown, our EV mileage is relatively low at about 6K for the year, so the car has been here to plenty for V2G!
The spread sheet shows our electricity and gas bills, the export payments and the PV generation and payments, along with the various totals used on the charts...
The upper chart shows the OVO bill (gas, electric/VAT) with and without the V2G payment.
The lower chart shows the net total after the PV export payment is included….
As you can see, our net energy bills come to an average of -44p per month…. so effectively no net cost!
I think this is a very powerful advert for the future of V2G or V2H… We get the car to do work helping to balance the grid and reduce the need for carbon based power and as a payment we effectively get free fuel for house and car, complete with the added pleasure of driving a quiet and clean electric vehicle…. what’s not to like!
