Can wind farms cause Black outs.

This is a new one to me, I think it must be just scaremongering and I sure there is something that can be done to smooth out the spikes.

The Scottish Government is considering more than 40 applications for major projects, which could clear the way for nearly 1,000 turbines.

Each wind farm could produce enough electricity to power thousands of homes, but objectors claim that even if just some of them were approved, the grid would become overloaded and trigger blackouts.

Campaigners cite the Czech Republic, which installed security breakers near its border with Germany, because its network could not cope with the electricity produced by its neighbours during peak periods.

The anti-wind farm lobby says a surge of electricity from turbines caused by high winds was to blame for a power cut last month that affected 200,000 properties in parts of the Highlands and islands.

The overload claims have been dismissed by the National Grid and energy giants Scottish Hydro Electric said it had positively identified the cause of the blackout as faulty equipment in a substation.

There is no evidence that adding more onshore wind generation will lead to blackouts.

SNP ministers are examining 41 applications for developments of 50 megawatts or more, a total of 966 giant turbines, including 10 in the Highlands, one each in Moray and the Western Isles and three in Argyll and Bute.

Andrew Mackay, a campaigner and electrical engineer from Tain, Easter Ross, said that when it was blustery, turbines produced “junk” electricity that could not be used.

He said: “We are going to get more power cuts because more and more junk electricity will end up on the grid.”

is he right? maybe!

But Michael Rieley, of Scottish Renewables, said: “There is no evidence that adding more onshore wind generation will lead to blackouts.” A spokesman for Scottish Hydro Electric Transmission said last month’s blackout was caused by a faulty relay.

He said: “Our investigation identified that the outage was triggered by a mal-operating electronic relay within Knocknagael substation, south of Inverness. A review of the network has been completed and we are confident that the cause has now been addressed.”
