There are 62 slides in his presentation and Alistair 'cantered' (his word) through them in 50 minutes - I will be much briefer than that. The first part is about electricity and the second about gas.
Electricity
Power station capacity margin forecast (OFGEM) |
The chart shows a forecast for the capacity margin - how much spare capacity we have in hand to cope with peak electricity demand, in case of plant downtime for whatever reason. The red line base case drops from around 14% in 2012/2013 - which is barely comfortable, down to 5% in 2015/2016 which is excrutiatingly tight. The red line assumes zero net exports of electricity to Europe. (We buy and sell electricity according to demand through a cable link to France across the English Channel). The bottom blue line represents a worst case with full exports which takes us down to 0% capacity margin. Ouch. We'd better not do that then.
The forecast is for increasing margin from about 2017 due to new plant coming online. However, quite a lot of the new capacity is delayed.
- Three new nuclear power station projects are delayed
- CCS (carbon capture and storage) investment has not yet produced any significant options
- Offshore wind is ramping up slower than was hoped
- Drax has just cancelled its big biomass plant project
It appears that we need gas as a bridge until we can get more renewables and nuclear online.
Gas
The trouble with gas is that everyone wants it - and supplies from the North Sea are drying up. For the moment we get about half our gas from the EU and Norway but this will decrease with the shortfall coming from Russia, North Africa and global markets. The recent crisis in Algeria is unlikely to increase confidence in North Africa and Russia says it has plenty for us - but it was unable to meet demand in February last year when the winter was very cold. Supplies to Western Europe were reduced by up to 10% for a few daysDemand for gas is increasing across the continent since the recent Fukushima crisis has triggered plans to close more nuclear plants.
The promise of shale gas continues as a promise only, delayed by bureaucracy even if it does eventually get the go-ahead - and it is already banned in France and Germany. Poland has just passed a new law allowing development but exploratory wells have shown underwhelming potential and local demand will be high.
Shale gas in the US has caused a glut in the market and a drop in price - but even at current rock bottom prices, the additional cost of compressing it to liquefied gas (LNG) and transporting it to the UK (since there is no pipeline across the Atlantic) would bring the price level with what we are paying now. Needless to say if we start buying this the price will go up. In any case, on the global markets we are competing with China and all the other countries wanting more gas.
The uncertainly around shale gas seems to be leading to a lack of investment in new gas fields and pipelines across Russia and the 'stans'. The Shtokman gas project in the Russian arctic has been shelved. The Nabucco pipeline which was supposed to diversify our supplies is going on but at a reduced scale.
Now Centrica have pulled out of a nuclear partnership with EDF claiming spiraling costs and longer timescales before any return on investment.

yes. I wonder what will happen if the UK government doesnt agree the guaranteed floor price needed by EDF who say "they [the government] know what they need to do".
