UK Electricity Statistics–Quarter 2

October 23, 2012

By Paul Homewood

 

 

The UK’s Department of Energy and Climate Change (DECC) have issued the latest quarterly statistics for electricity generation. The key points are :-

 

  • In 2012 Q2, total electricity generated fell 0.5 per cent from 84.9 TWh in 2011 Q2 to 84.4 TWh, the lowest level for this quarter since 1998.
  • Coal fired generation rose by 59.9 per cent from 19.1 TWh to 30.5 TWh, its highest second quarter level for at least 14 years.
  • Gas fired generation fell 32.1 per cent from 37.1 TWh to 25.2 TWh, its lowest level for at least 14 years. This was due to high gas prices, with several gas stations being run at minimal or zero levels as a result. 
  • Nuclear generation fell 3.3 per cent from 19.2 TWh to 18.5 TWh. Wylfa reactor 2 shut on 25 April 2012, leaving Wylfa reactor 1 as the sole Magnox reactor in the UK. (Oldbury fully closed in February 2012).
  • Wind generation increased from 3.59 TWh to 4.25 TWh, raising its share of total generation from 4.2% to 5.0%
  • Net imports increased from 1.53TWh to 3.19 TWh to fill the shortfall in production, as demand increased by 1.4%.

(Comparisons are all with Q2 in 2011).

 

The following chart shows how the share of generation has moved over the last three years. Over this period wind power has increased its share from 3.1% to 5.0%. Other renewables have barely increased their share at all, rising 4.6% to 5.2%.

With coal currently contributing over 36% of the UK’s electricity supply, it must be of particular concern that six of the fourteen coal power stations presently operating will be forced to close in the next three years, because of EU emission regulations. 

Unfortunately we are now seeing what happens when you let idiots run your energy policy.

    It’s all a lesson in the truth of the adage: “Elections have consequences.”

    I’ve very recently downloaded the electricity generation files from the NETA site for 2010 to Oct 22 2012. It seems to me that the files must in some way be different from the ones you used. (Not difficult to imagine.) They are in Excel CSV format, and the two full year files have over 17000 rows of data (half hourly data), and this year’s has about 14000, thus they are substantial, and approach the limit of what my computer and OS can handle. I find that WIND (sic) has this year produced around 3.5% of the UK TOTAL (sic) output. I am ignoring the interconnection data, which is not really meaningful unless one is interested in how the grid system will cope, I guess. In any case it is not a major player when one is interested in the contribution of WIND. I’ve made loads of analyses and graphics from the data, some of which you are unlikely to have made, I think. Could supply graphs to you by email attachments if you wish. At around 17000 points some of these are fairly large. I find them quite fascinating. The data contain several “errors”, presumably clerical since generation of zero or very low power is highly unlikely. I would have noticed it and so would everyone else. Nevertheless. groups of zeros occur, indicating lack of editing by the people who generate the file. I’m trying to get in touch with them.

    Cheers, Robin
