Possibly because of the UK having less heavy industry and importing our 
products that rely on heavy energy usage from China or the far east etc.

Industries that were once heavy users of electricity probably had 
contractual agreements stating that it wouldn't be used in peak domestic 
times.

Is that 30% in the past 6 years mainly due to the installation of more 
wind turbines which produce little when the wind barely blows for 
periods of weeks? Possibly also solar which produces little during the 
winter and nothing at night. Has there been a corresponding 30% increase 
in the backup capacity to fill the shortfall when wind fails? If the two 
are not matched then it's rather silly to rely only on extra 
intermittent power generation, especially during a cold winter.

Although unlikely to happen within the timescales the green lobby would 
like there is also the move away from gas and oil to electric for 
central heating that will increase demand for electricity.
