Maybe more reliable figures would be those found in 'Predicting future GB heat pump electricity demand' published here?
In a typical year in the 2050s the heat pump electricity demand was calculated to be 80 TWh, of which 34% will be used to provide DHW, and the total GB electricity demand was 400 TWh. In a cold year the demand increased, but only to 412 TWh, which is a 29% increase on the total GB electricity demand in a cold year in the 2020s.
The calculated peak heat pump electricity demand in a cold year in the 2050s was 37 GW. The peak GB electricity demand was 89 GW which is 46% greater than the current 2020s cold year peak.
In a cold year in the 2050s, the annual load factor of heat pumps alone was around 28%, whilst the annual load factor of the total GB electricity demand was 53%. This is a reduction of nine percentage points compared to the annual load factor for the current GB demand in a cold year.
Which indicates that, yes there is a requirement to increase the capacity for peak and annual demands - but only 46% and 29% respectively. |
Like most people , you do not seem to understand the difference between power [ MW ] , and energy [ MWh ].
A generator turns Kinetic energy into Electrical energy .
https://www.generatorsource.com/How_...tors_Work.aspx
and no power is produced until that energy is used at the end of the line / grid . So the correct term for a generator output is KWh .
And just like Miles Per Hour , which is a rate of travel at one moment in time , Kilo Watt hour is the rate of energy output at one moment in time , and also the total output after 1 hour .
So the correct term for generation capacity is in KWh, although very few people understand it .
And the extra 200GWh needed for heat pumps to work is constant , and therefore about 400 % increase on present generation capacity
