Once again after a bit of a blow, proponents of bird culling are trumpeting how wind can come to our rescue. At least the BBC piece covers why but fails to connect dots. The dry anticyclonic spell in September (and most of the spring and summer months) don’t get a mention, but see for yourself (red arrows indicate the ‘robust response’ of wind power to anticyclones, the blue box indicates when nuclear dropped for the reasons outlined below)
Would you want to rely on wind when a cold anticyclone covers our Islands in winter?
…for a 24-hour period yesterday, spinning blades produced more energy than splitting atoms.
Wind made up 14.2% of all generation and nuclear offered 13.2%.
It follows another milestone on Saturday, when wind generated a record amount of power – 6,372 MW, according to National Grid.
This formed nearly 20% of the the UK’s electricity, albeit at a time at the weekend when demand is relatively low.
But wind power’s ascendancy over nuclear is expected to be temporary.
The situation is caused by windy conditions boosting the output from turbines at a time when eight out of the UK’s 15 nuclear reactors are offline.
EDF Energy said current ageing reactors are down for a number of reasons:
Sizewell B is in the middle of a planned “statutory outage” for maintenance and refuelling
Hunterston B Reactor 4 is down for maintenance, expected back in early November
At Dungeness B, one unit is being refuelled and the other is expected back online soon after being shut down after a fault on a boiler pump was discovered.
The four reactors at Heysham and Hartlepool were taken offline in August after a crack was found on a boiler spine.
