GE is investigating a second blade failure within a year at a wind farm in Sweden using some of its latest onshore turbines after an incident witnessed by a family with children nearby.

A blade on one of the GE 5.3MW-158 Cypress machines at the Bjorkvattnet project became partially detached on Thursday evening, confirmed renewables operator OX2 which manages the site.

Nobody was injured but the incident, which resulted in some debris falling to the ground, was seen by a family with children picking berries nearby.
