Yes they are.Quote:

Again, read the report.
Plenty of renewables blowing around up here today... 33c and blowing its backside off
Less than half here are running. The rest are parked.
Siemens spokesperson is in the news today, quoted as saying gas plant would have tripped also if it had been in the location of the wind farms. Seems to be saying proximity to point of initial failure is a major factor in shut down, not energy source itself.
I am aware turbines will park once wind gets too strong, but frequency / voltage management across the network is not my field.
So in a Utopian world with Solar, Wind, Tidal and batteries, but no big kick arse fossil turbines and minimal hydro, being where we are, how will the network be synchronized, so we get a nice clean power feed ?

Its not pointless, renewables are certainly here to stay, but simply trying to power on with renewables, without an alternative to baseload generation, will often.....leave us in the dark:D
Engie wants to be out of coal within 3 years, so there is a probability, as its a multi national company, they purchased a package, but there is a lot more to it than that, more than we know, repatriation, who has the money, the jobs, the effect on lack....yes LACK of baseload generation in peak periodsQuote:
