The Mass CEC WTTC facility tested a single GE prototype blade made in France. GE Vernova manufactured 130 blades for the Vineyard Wind project, in Gaspé, Quebec, Canada, and did not receive full structural or torsion tests before installation.
Massachusetts failed the statistical sample test of any of the 130 blades manufactured for Vineyard Wind, which, in hindsight, could have caught the defective Canadian blades.
.
The Massachusetts Wind Technology Testing Center was originally built for shorter blades; engineers had to cut the prototype blade in two to fit it inside the testing center. Industry observers have pointed out that this spatial limitation prevented full-length structural assessments—including specific full-blade "torsion" (twisting) tests—resulting in data being extrapolated rather than physically measured. No "torsion" tests were performed.

The faulty sensors and associated blade failures led to a legal and financial dispute, resulting in over a billion dollars in delay claims between Vineyard Wind and manufacturer GE Vernova. Suffolk Superior Civil Court 2684CV01041.
