Medium-to-large wind turbine generates about 2MW each. LY2 generates (sorry, USED to generate) up to 560MW.
So much for so-called reliable coal fired electricity generation!What a silly statement to make and do we really need to go through this again?
Loy Yang A has spat a generator that may keep it out of action for 7 months:
ONE windmill turning for ONE day will produce more power than Unit 2 at Loy Yang until Christmas!!!
Suggest you spend time going through the real data and then get back to us.
Also you might want to check Youtube out, start with typing in "Wind turbines blowing up", I wonder how much power they will make between now and Christmas?
Please provide a credible link to demonstrate that 230 equivalent wind turbines have 'blown up' anywhere, anytime.
Very narrow thinking and your final comment also assumes the entire coal fired network has done the same.
NSW, Vic and Qld have something like 19,000 MW of coal fired generation capacity being supplied by around ~52 turbines with a nominal availability of 85%, reliability is power to the grid at full capacity, so 16,000 to 17,000 MW at anyone time. The Peak output yesterday was 17,030 MW.
When that coal turbine failed at Loy Yang, what came to the rescue?
You guessed it, a stand-by coal turbine as Vic is still producing up to 4300 MW of coal fired power.
Australia has around 5700 MW of wind generating capacity with an average turbine size of 4 MW, so 1425 individual turbines with a likely rated availability 90 - 95%, however with a nominal output of 35% which reduces your average output from nameplate of 5700 x 95% availability x 35% nominal output = 1895 MW or a messily 1MW per turbine. An overall real time availability of 33%.
Also note using the NEM data from the last week, (also a windy week), the highest output was 3700 MW and the lowest was 450 MW. So when the winds failed to blow, who came to the rescue?
Lets list them shall we
- Gas Steam
- and worst of all, diesel!
I've said it before and I'll say it again for the benefit of DirtyBallast and any supporting cast.
- Wind is very good and cost effective at supporting and expanding the capacity of existing hydro.
- Wind is also ok to make supplementary contributions to the existing thermal fueled grid up to a limit.
- Wind is a horrible source of power when you exceed the reasonable limit and therefore pay for the same amount thermal generating capacity to be sitting there waiting to cover its ar$e. As a result the thermal generation capacity is often high cost to very high cost and you are paying for things not to be used and this includes the gas contracts which is why Pelican Point was not ready when SA needed it 2 years ago when wind failed to fill the gap created by the loss of Northern.
