h/t it doesn’t add up

If you wonder what dopey Emma Gatten forgot to mention, read on:

You will recall her report earlier today, which described how electric car drivers could earn £725 a year simply by selling power back to the grid. My first reaction was that the numbers simply did not stack up.

I have since looked at the actual study, Project Scirius, and I now know why.

Below is the key paragraph:

Given that the typical domestic electricity tariff is around 18p per KWh, a payment of 30p is clearly not viable for energy suppliers, particularly since they could buy the same amount of power on the wholesale market for about 5p/KWh.

The figure of 30p is clearly heavily subsidised for this tiny pilot project, presumably from taxpayer funds.

Based on the above numbers, the average export is 3200 KWh a year, giving £80/month at 30p. As the savings are £30/month, the cost of charging the car up in the first place would be £50/month, equating to 18.7p/KWh.

In short, her report considerably overstates the savings likely to accrue to electric car drivers in the real world. Indeed, many probably won’t save a penny.

Emma Gatten has grossly misled her readers by simply regurgitating the figures given to her in the press blurb, rather than doing a few easy checks herself.

Such is the shoddy standard of Telegraph journalism these days.
