The Shell project you mention was off south-east England - the London Array.

When Shell pulled out Masdar joined up to replace them, so its still going ahead.

I agree the supergrid concept is very important - by expanding our grids and making them more intelligent, we can free ourselves of energy sources that deplete and pollute entirely.

I should have been more specific; I was referring to the Cirrus Array in the NorthWest.

Ooops - sorry - I didn't realise they had pulled out of another project.
