Chris that's true, but the problem is load balancing the demand peaks at early morning and early evenning. The chances of wind following that demand profile are really slim. Storage will be needed even if only to acomadate daily demand variations.
So long as you are above the demand profile, there is no real problem, you just sell your excess. It is worth remembering that nuclear does a very poor job of tracking demand, coal a little better, gas even better and hydro the best of all. The UK has some pumped hydro storage now. I mention below that chemical storage in the form of methane might be a good fit with the UK's energy infrastructure.

To whom?
Chris, I'm a fan of wind owing to its reported high eroei, but feel there are some significant engineering and market regulatory steps need to be taken to make this truly viable. This would include pump storage and balancing against gas fired plant. I also kind of like the idea of building a parallel HVDC grid for renewables that sits along side our existing HVAC grid.

Do you think these engineering and market regulatory steps can be accomplished within the 2020 time frame as announced?

Euan,
Sorry to leave this unanswered. I know of at least one electrical connection between the UK and France through the Chunnel. By 2040, France may be interested in excess wind power since their renewable development is somewhat hindered by their present reliance on nuclear power. You'll likely be seeing excess at about that time that you won't want to put towards industry all the time. So, the timing may work out pretty well. There are other places where you might want to build an 8 or so GW line for export. The lines on the Risk board look like a rough draft of what might be useful.
