The UK ran critically low on gas during the cold weather, coal power stations took over from gas in providing the bulk of electricity demand, and the country’s interconnectors both helped and hindered system security during the cold weather.
“For me the report shows just how complex our interconnected energy system is,” says Dr Staffell, “There are critical questions about resilience and security of supply, which thankfully are becoming easier to answer through data coming out of projects like Electric Insights.”
The report is the 7th Electric Insights report, part of a series commissioned by Drax Group. Dr Staffell produces the report each quarter in conjunction with other experts at Imperial College London.

2. Running low on gas
The cold weather in March not only affected the power system, Britain’s
gas network was also stretched as demand outstripped supply. ................................................
The shortage was partly due to unusually high demand for gas during the cold
weather (see chart below). Five in six of Britain’s homes and offices are heated by
gas.1 On the coldest day (March 1st), daily gas demand spiked to 4,600 GWh, a level
not seen since 2010. For a sense of scale, the extra gas demand due to the cold
weather was comparable to the entire country’s electricity demand.
A further worry for the gas system was the historically low levels of gas held in
storage. This was not helped by the cold weather coming unusually late into the
heating season; gas in storage is likely to be at a greater level earlier in the winter
months. Last year, Britain’s largest inter-seasonal gas storage site (Rough) reached
the end of its economic life, and was deemed unprofitable. It discharged for the
last time over winter, and was finally emptied by mid-January. ...........................................................

The amount of stored gas is at its lowest since 2010 (see chart below). In the week
surrounding the Beast from the East, 26.7 TWh of gas was consumed, 8.4 TWh of
which came from storage (see the sharp dip at the start of March). In comparison,
total electricity demand in that week was just 6 TWh.
The ability of the gas system to accommodate significant swings in energy demand
over daily, weekly and seasonal timeframes is one of its major strengths. As coal
