Ed Miliband to visit China amid wind farm security fears

A spokesman for Mr Miliband’s department declined to comment on “speculation”.

It comes as he is seeking to drum up investment for wind farms, solar farms, batteries and other energy projects in Britain, as the Government races to deliver its promise of a “clean” power system by 2030.

But the attempt to thaw diplomatic relations comes at a sensitive time, with a cross-Whitehall review of UK-China relations underway.

Green Volt concern

This month, MPs also raised concerns about Chinese involvement in a major wind farm project which is said to have rung alarm bells in the Ministry of Defence.

Mingyang Smart Energy, which is based in China, has been selected to provide the turbines for the Green Volt floating offshore wind farm, off the coast of Scotland.

But MoD officials are said to have warned that the turbines, equipped with an array of sensors, could be used for spying or give Chinese engineers “a legitimate excuse to visit any time for maintenance” and “install almost anything they like”.

Andrew Bowie, the Conservative shadow energy secretary, said there was a risk that the “green revolution will come with a ‘made in China’ label”.
