To ask the Secretary of State for Energy Security and Net Zero, whether he has made an estimate of the additional grid capacity the UK will need in 10 years’ time to meet the increased demand for electricity and increased renewable supply. (160099)
Tabled on: 07 March 2023
Analysis set out in the Electricity Networks Strategic Framework, jointly published by BEIS and Ofgem, suggests grid capacity would need to increase to accommodate a peak electricity demand of between 85-90GW by 2033, up from around 60 GW in 2023.

This is an insufficient answer. It implies limited roll out of electric vehicles and all electric heating systems. The Minister does not go into the issue of how much extra grid capacity is needed to take into account the heavy predominance of wind power from Scotland needing transport to the heavily populated parts of England, nor how much extra capacity is needed to handle switching from renewables to stand by fossil fuel power when the wind does not blow. There is little sign of sufficient investment in grid capacity or local network capacity to match the ambitions to switch large amounts of energy use away from gas, diesel, petrol to electricity. The bulk of our energy use today is fossil fuel dependent.
