Flywheel storage would be a good idea there.
Don't they have a dump load of some kind? |
With large scale wind turbines you don't use dump loads, you tend to just shut them down, part of why they work so well for meeting the energy demand is that they can be shut down and started up very quickly, so it sounds like poor management.

With enough energy you can do almost anything. They could make gold from nothing if they wanted to. I'm sure there must be something useful that the world needs that they could throw that excess energy at. Even if it's just sucking in air and removing CO2 from it it's better then turning them off and wasting that energy.

That article raised a question in my mind. What is the most cost effective way to store and reclaim energy on a large scale? Let's say for a few hours, or a few months. I guess the answers could be different. Is the cheapest net financial option just to shut the turbines down?

Pumped-storage hydroelectricity is 70%-85% efficient, compressed air 70%, flywheels up to 90%, but the latter is definately smaller scale than the first two.
The article stated that normally excess power is pumped into England's grid, but this time a malfunction of some sort didn't allow that. |
TOO MUCH renewable power? Now there is a good kind of problem to have...

connected to a grid-tied inverter (which was illegal in his country), and his electric meter was the new LCD type, that won't run back-wards!! :eek: Any PV power above what he was burning, went out to the grid and he was billed for it! (Like he had Used that power). |
