Naguabo windmill damage

All 13 of the windmills at the Naguabo wind farm have at least 1, and many all 3, broken blades.

A good engineer would design with this possibility in mind. Blades would be designed to break away with minimal damage to the head and gearing. I looked on the manufacturer's site to see if this was the case with these. I found nothing.

Does anyone have any knowledge of this? Either specific to the Naguabo site or in general?

Replacing the blades seems relatively inexpensive, at least compared to the cost of replacing the whole mechanism.

It might mean the difference between restoration and abandonment.
