The 1.1GW agreement, signed at the China Wind Power (17-19 October) event in Beijing, covers three blade types: the LM 66.9 P, and the newly developed LM 66.9 P2 and LM 69.0 P.
It follows a 140MW pre-agreement signed last year, and is the largest deal between the two companies since 2010, they stated.
LM Wind Power will manufacture the 66.9-metre and 69.0-metre blades for both Chinese and international markets at its plant in Qinhuangdao in north-eastern Hebei province.
In January 2017, LM Wind Power announced that the first variant of the blade series, the LM 66.9 P, had been installed on a prototype of Goldwind’s 3MW platform, the GW3S.
It will now develop the LM 66.9 P2 for stronger wind speeds, as well as the LM 69.0 P, which is an extension of the original 66.9-metre variant.
Goldwind unveiled its 3MW platform in November 2016 and announced a 4MW platform for medium wind speeds in November 2017.
At the time, Goldwind said it expected the model to be commercially available in 2019.
