From NOT A LOT OF PEOPLE KNOW THAT

Natural gas accounts for 43% of the UK’s primary energy consumption. In comparison, renewable energy only supplies 4%.
Our reliance on gas though is much greater in winter months:

And if you look at hour-by-hour data, the peaks are greater still, as the National Grid chart below shows:

This graph is for yesterday, Dec 10th. Demand for gas ramps up from around 310 mcm at night to 430 mcm in the early evening. One mcm = approximately 11 GWh.
So a rate of 430 mcm/day equates to 4730 GWh, or 197 GWh per hour.
While supply remains relatively constant, these peaks in demand are met by reducing what is known as the linepack – effectively the amount of gas within the gas distribution network. This, of course, is something that the electricity grid cannot do.
In comparison with the daily peaks and troughs of gas, electricity storage is miniscule. Pumped storage capacity is 2.8 GW, with the biggest, Dinorwig, rated at 1.7 GW with storage of 9.1 GWh. Battery storage is much tinier still.
Based on the decline in linepack, we would need about 70 mcm each day to top up at peak demand – that is 770 GWh.
In any event, all of the electricity storage we have will all be needed just to balance peaks in electricity demand.
Yet our policymakers continue down the road of electrification, seemingly oblivious to the realities.
