Ever wondered about the sources of power in the National Grid

Sometimes you come across a website that truly surprises. Gridwatch is one of those. In one real-time screen Gridwatch provides the information on where the UK’s electricity comes from – coal, nuclear, gas, wind, and from interconnectors. I’ll not witter on about it, but let you marvel at the dashboard of gauges and monitors.

From just a little inspection of the gauges and monitors I’ve deduced that,

  • So little of our electricity is generated from wind is a poor return on the £billions we’ve invested
  • Coal-fired power generation is a reducing element of our power spectrum, with the use of gas increasing
  • I’d imagined that nuclear generated electricity would be higher. I guess it’s a result of our aging nuclear power stations being off-line for maintenance, or even closed.
  • Some sources of power generation are held in reserve, such as oil and hydro
  • Pumped hydro-electric power generation sources amount to just 1.5% – such as Dinorwig
  • Through the interconnectors, we’re a supplier of electricity to Ireland, and importer from France and Netherlands

If you click on the same dashboard view for France [by clicking on the French icon in the top left hand corner] it shows that 100% of electricity demand can be generated from nuclear power stations, with a small % from Hydro. [Click on image to enlarge].
