According to
Herald Scotland 2 May 2011,
Row after wind farms ‘turned off’:
Six wind farms were given six-figure payments to switch off their turbines
because the Scottish grid network could not absorb all the energy being
produced, it has emerged.Research by the Renewable Energy Foundation (REF) found energy companies
were paid a total of £900,000 for stopping the turbines for several
hours between April 5 and 6 this year.The REF said some of the payments were as high as 20 times the value
of the electricity which would have been generated if the turbines
kept running.The National Grid makes constraint payments to power stations that agree
to stop generating in order to stabilise the network.It happens when the grid system or a section of the system is unable
to absorb all the electricity being generated, and some generators that
are contracted to generate are asked to stand down.
Sounds like they just need to fix their prices.
Adding some local storage of some kind would also help.
