SSE have abandoned their plans to extend Hadyard Hill wind farm with another 22 turbines. South Ayrshire’s Planning Committee had recommended refusal which meant a Public Local Inquiry would be held. SSE stated that they “decided for commercial reasons not to proceed with this particular application.”
We are delighted. The proposal would have had serious negative impacts on the Stinchar and Girvan valleys and many homes would have suffered unacceptable effects.
I’m an expatriate Scot in the State of Virginia, retired from the Federal Energy Regulatory Commission. In the two years before California unjustly put the blame on their Governor, for their appallingly bad electricity delivery services, which I will just call their “grid”, there was a root problem and a derived problem.
This is relevant to ALL wind turbine nonsense, because they provide ZERO dispatchable power.
California’s root problem was that the standard reserve dispatchable power, in places as fortunate as the Pacific Northwest, is hydro. It depends for its capacity upon the previous winter’s snowfall, and subsequent rainfall, in the mountains above the dams.
There wasn’t enough snow and rain, in the Sierras and the Cascades.
Dispatchable electrical power is that which can be summoned in addition to what is running, at short enough notice that some added load will not slow down the generators enough that differing responses to overload will cause AC phase differences of a significant fraction of 1/120th of a second. That’s how long it takes for 60 Hz AC to go from maximum positive to maximum negative. You obviously have a disaster if one generator is sending voltage opposite to another.
Instead, a proper grid will kick off the supplier of the resulting current surge.
When you come to a stop light in a motor car, you let the engine continue running. This is a waste off petrol, of course, but it is a courtesy to everybody else.
Likewise, if you own and operate gas turbine electric power generators, you can provide dispatchable power if you run at half power, or even spinning the turbines at zero electric output, but in phase.
The outrageous thing was, that this means the suppliers of dispatchable electric power, by offering “spinning reserve” could charge prices equivalent to the ransom of the grid!
For that reason, a grid manager with 1000 MW of nuclear, 1000MW of coal, 2000 MW of gas turbines, and 5000 MW of wind “turbines”, has exactly 4000 MW of dispatchable power. Twice as much wind power capacity adds exactly nothing to the dispatchable capacity.
