December UK Electricity Production by Fuel Type including renewables

December's UK electricity production graph makes interesting reading:

  • Peak demand was 50.6 GW, reflecting the gradual decline in peak demand over the last ten years or so
  • Wind (green) made a useful albeit sporadic contribution
  • Solar PV (yellow) was negligible, and nonexistent at peak times.
  • There were several high-peak-demand days with almost no contribution from wind
  • Gas (light brown) is now taking virtually all of the strain of meeting fluctuating demand as coal is phased out
  • Average demand at 36.5 GW is 14GW below peak demand giving an opportunity cost of not having domestic demand response of  £110 billion at present non-carbon firm supply capacity cost (i.e. nuclear). That's £70 million a week that could go towards the NHS for 30 years.
So - if you don't want carbon and you don't want nuclear, you had better start getting a few of your friends to flatten their demand!
The good new is that 10% of consumers are already aware of this as an issue, including PV owners, those on economy 7, and a few hundred thousand geeks like you and me. So we are well and truly on the adoption curve - but with a long way to go -so get time-shifting.
