Not a Lot of People Know That by Paul Homewood 11/21/2020
We have been looking at the potential impact of electric cars on grid capacity, but this is likely to be swamped pretty quickly if the roll out of air heat pumps is carried out as planned,
The government’s plan is to be installing 600,000 a year by 2028, some of which will be in new build homes.
According to the
Tradesmen Costs website, heat pumps would range from 6 KW for a terraced house to 9 KW for a typical detached. If we take 8 KW as the norm, 25 million homes would potentially need 200 GW of grid capacity, purely for heating alone. [The 200 GW is overstated – see correction below]
This assumes that they will all be working simultaneously, a not unreasonable assumption, given the need to heat houses in the early morning.
