Absolutely. I would go along with you there.
Just so that the problems - quite apart from stability - can be seen take a look at this.
This is an imaginary country (actually very closely modelled on Ireland). The installed wind capacity is 20%+ and the Government requirement is to
take this to 30%+ and to remove coal fired stations. (This is very close to real life - no this is the real life situation)
I am not going to go into market pricing and how wind adversely affects the cost to you as it is complex, but I want to take a look at the effect of
the above scenario on capacity.
The capacity of the system given a steady system demand is catered for with a small margin when no wind is blowing.
Now we remove the coal fired capacity.
No problem when the wind is blowing, but when there is no wind there is a requirement to draw 1.6GW from somewhere. In the case of Ireland and England
this capacity is provided by what are called interconnectors. The grid in Ireland can be supplied by the grid in the UK, and the UK has an
interconnector to France.
1.6GW is way over the capacity of a 'standard' power station - more like the capacity of a nuke.
Ireland's capacity is 1/10th of the UK so this would mean 10 small nukes for England to fulfil that capacity if it could not draw from France.
What does France have? Mainly nukes!
The UK depends for the bulk of it's gas on Russia, as does most of Europe. Ireland gets gas through NI when it is not using it's own capacity which is
small. If for whatever reason Russia pulled the plug on the gas - or the plug was pulled because of war, bye bye UK power production, hello
I would imagine that you could apply this 10 times again to the States - but you have the advantage of your own gas supply and no dependency on
Russia. However, if like Europe you go down the route of 30%+ being generated by wind, you too will have to build new CCGT stations, or Geothermal or
tidal stations to make up the shortfall. (Or 100 more nukes!)
"The wind is always blowing somewhere" is the favourite con of the proponents of the wind power scam. Yes, indeed it is but wind blowing in Minnesota
will not help Florida in a heat wave. The transmission losses are conveniently ignored in this scenario, and of course each geographical area as far
as wind goes would have to carry many times over it's local capacity requirement on the off-chance that it is the only area that is currently
operational. Patently this is just pure nonsense.
CCGT (Gas) YES
Nuclear - Maybe!
