CCGT Gas

CCGT Gas is still the main fuel source for electricity generation in Great Britain, and also a major provider of energy for heating and in industry.

With the intermittency of the major renewable sources, a main advantage of gas is that it offers flexibility and reliability. No other current major available source can offer these to the same level as gas.

The National Grid generally anticipates an increase in generation from distributed gas plants, but a decrease in generation from transmission-connected gas-fired power stations.

It is hard to see how the decrease in transmission connected power and energy generation can be achieved without alternative approaches to dealing with the intermittency of renewables.

Storage

Great Britain did have a major storage facility for natural gas, but this was closed in 2017. GB storage now amounts to about 16.5 billion kWh, or about 8 days' supply.

Security

Great Britain's continued dependence on imported gas presents a risk to security of electricity supply.
