DECC: UK imported more than half its energy in Q2 2013

The latest DECC Energy Trends was published today, and it's no surprise that the decline in indigenous energy production has continued. The killer statistic is:

In the second quarter of 2013 net import dependency rose to 51.4 per cent, up 9.6 percentage points from the second quarter of 2012.
The chart on page 10 tells the story:
Uk energy import dependency
Here's the reasons, all comparing Q2 2013 to Q2 2012...

Coal: Production was down 24.3% on a year ago, and the proportion of our coal that came from imports rose from 81.7% to 93%. These imports came mostly from Russia (nearly half of the total!), USA and Columbia.

Oil: Production was down 13.4% on a year ago, and the proportion of our oil and oil products that came from imports rose from 40.5% to 45.1%. On a related note, the closure of the Coryton refinery resulted in a 5.6% drop in production of fuels from oil.

Gas: Production was down 2.8% on a year ago, and the proportion of our gas that came from imports rose from 43.6% to 52.5%. These imports came mostly from Norway, Qatar and the Netherlands.

Electricity: Production from nuclear power fell 16.5% due to several outages, but wind and PV generation rose by 58.6% (due to increased capacity), and hydro generation rose by 29% (due to higher rainfall). We imported 4.4% of our electricity.

Renewables
The key points here are:
  • Share of electricity supply up from 9.7% to 15.5%, due to increased capacity for wind and PV and increased rainfall to power hydro stations. There was also more generation from power stations converted to biomass, although co-firing with coal has reduced.
  • There's now 1,918 MW of capacity on a feed-in-tariff, 127 MW of which joined during Q2 2013.
  • Total renewable capacity in the UK was 19.5 GW, compared to 14.2 GW a year ago.

Large Combustion Plant Directive
There's a helpful table (page 72) that shows how many of the coal power stations that were running over winter 2012/13 won't be running this winter. It's for reasons like this that Ed Miliband's promise to freeze energy prices seems a bit foolhardy.
LCPD hours remaining

The status of the plants that opted out is given in another table:

This shows that there's 5,050 MW of coal plant that ran last winter and won't be running this winter, and another 2,268 MW of oil plant that has shut - this didn't run much last winter, but when it did run it was urgently needed... On top of this there's another 1,730 MW of coal plant that is currently open but will close at some point during this winter. DECC also notes that:
From 1st January 2016 the remaining large combustion plants will be subject to more stringent emissions controls outlined in the Industrial Emissions Directive (IED). Plants that chose to opt-out of this directive will be limited to 17,500 hours between 2016 and 2023.
So there's more shutdowns to come!

UK electricity shortage - I told you so...

Well, surprise surprise, with the shutdown of a number of coal fired power stations only a few months away now, it's suddenly in the news:

Consumers are being warned they face higher energy bills as the UK becomes more reliant on energy imports. In a speech, Ofgem chief executive Alistair Buchanan will say that falls in Britain's power production capacity are likely to lead to more energy imports and customers paying more. The energy watchdog predicts power station closures could mean a 10% fall in capacity by April alone.
It's not just me that knew this was coming, the Large Combustion Plant Directive, which is the cause of the shutdowns, was proposed in 2001, and came into force in the UK in 2007. So we were warned well ahead of time. There were even reports by organisations such as Deloitte that same year, trying to warn us about what was coming:
This paper indicates that if we are to succeed with the collective objective of ‘securing clean, affordable energy for the long-term’, there is a clear and immediate need for change.
...
The importance of the energy debate should not be underestimated – future policy will directly affect the welfare and security of our country, our people and our economy. This is a time for clarity of thought and analysis. Let the debate begin – but not take too long to reach a conclusion.
By the way, the LCPD basically said that we either had to clean up our coal fired power stations with flue gas desulphurisation, or only run them for a further set amount of hours, and definitely close them by 2016. Because gas has been pretty expensive in the past few years, coal plants have run more than might have been expected, so they are hitting the running hours limit before the final deadline.

I wouldn't be surprised if the next thing that happens is that we keep running these dirty old coal plants, and just pay whatever fines are due as a result...
