Handling potential shortages
DECC has a number of ways to help minimise the impact of an electricity or gas supply emergency. As a primary measure, we can instruct power stations to use alternative fuel sources to generate electricity, as part of the fuel security code. Following extensive consultation, this code was revised in October 2007. The following documents explain the background to the fuel security code:
The revised code takes into account changes in the electricity market since the British Electricity Trading and Transmission Arrangements (BETTA) were introduced, and it reflects changes in the structure of the energy industry.
Electricity supply emergency code
If a prolonged electricity shortage affects a specific region, or the whole country, electricity rationing may be necessary. The electricity supply emergency code outlines the process for ensuring fair distribution nationally while still protecting those who require special treatment, using a process known as 'Rota disconnections’. The latest version of the code is shown below:
Handling gas and electricity emergencies
Both codes above are designed to mitigate the effects of an energy supply shortage. However, circumstances such as severe weather or damage to infrastructure could lead to an emergency situation. We work closely with industry to understand and plan for this, and regularly hold exercises to test the effectiveness of these plans. Additional advice on handling emergencies is available on the Directgov: Preparing for emergencies web pages.
The National emergency plan for downstream gas and electricity was most recently revised in 2010.
