Renewables 'too much power' problem is really nuclear's fault

Electricity nerds were getting excited (April 17th) as the national grid issued a 'negative reserve active power margin' notice, meaning that for North West Scotland there was too much power on the grid. According to the Daily Torygraph, who write for the renewable hating Tory hordes in darkest Surrey, this crisis is  the fault of renewable energy. The 'emergency' scenario is marked by the fact that the National Grid:
'could be forced to issue unprecedented emergency orders to power plants to switch off........Businesses will also be paid to shift their power demand to times when there is surplus electricity, as the UK energy system struggles to cope with the huge expansion in subsidised renewable power.'

Later on in the same article, there is an obscure mention to the fact that wind and solar farms may be encouraged to turn down their generation because of 'inflexible' generation, which of course is mainly nuclear power.

So let's get this right, the Torygraph is saying that nuclear power plant can't or won't turn down their power stations, so it's windfarms and solar farms that are the problem?

The strange thing is I often hear nuclear power industry representatives going on about how nuclear power is flexible and can turn up or down when required, except that in the UK it doesn't happen, not even with the newest station Sizewell B. There is confusion over whether future nuclear power stations will be able to vary their power, but I am pretty confident they won't.

Why will nuclear power stations never be turned down (voluntarily that is) in the UK? Well first, because nuclear are always given grid priority - that is the policy of the British state -  and renewables will get the blame as a result for any resulting 'emergency' measures. A few years ago EDF was busy arguing that renewables should be restricted to 25 per cent of electricity supply precisely because they didn't want or could get their nuclear power stations turned down. This is now more or less government policy is seems - fantasy nuclear will provide the rest of the required non-fossil generation. Second, of course, following on from this latter sentiment, I am confident that in future there is no chance of new nuclear power stations being flexible because there will probably be no new nuclear power stations (apart from some small failing 'smr' demonstration maybe) actually built!

A French Economy minister appeared on Andrew Marr's show recently to declare that a final investment decision for Hinkley C is only 'weeks or months' away - as it has been for the last 4 years! I suppose the delays in Hinkley C must be renewables fault somehow too!


NOTIFICATION OF INADEQUATE NEGATIVE RESERVE ACTIVE POWER MARGIN issued for the period from 13:35 hrs to 17:00 hrs on Sunday 17/04/2016 has been cancelled For North West Scotland
