What do you think of Suzlon's quality, +Russell Davison? About three years ago, a Suzlon had a blade fly off on an operational project in my area. Supposedly it was an engineering flaw in the design. Have they improved?
Hi +Kevin Williams , I suspect this was about 4 years ago when it happened :

"Suzlon Energy Ltd. (Pune, India), the world’s fifth leading and India’s largest wind turbine manufacturer, has announced a retrofit program to resolve blade cracking issues discovered during the operations of some of its S88 turbines in the United States.

The retrofit program involves the structural strengthening of 1,251 composite blades (417 sets) on S88 (2.1 MW) turbines, of which 930 blades are already installed, while the remaining blades are in transit or inventory.

“We have a close working relationship with our customers, and this program is a proactive measure to safeguard the interest of all our stakeholders,” says Andre Horbach, CEO of the Suzlon Group, in a company press release. “The retrofit program is designed to minimize impact for our customers and Suzlon.”

Horbach added that the company, with its integrated global value chain and in-house blade design and manufacturing capabilities, is equipped to resolve the issue within a short time frame and in a cost-efficient manner: “We are in close contact with all our customers and are keeping them fully informed of the progress. We expect no impact on the order and execution pipeline.”

The six-month retrofit program will be carried out by maintaining a rolling stock of temporary replacement blades to minimize the downtime for operational turbines. The program will use Suzlon’s global technical capabilities and its blade manufacturing and service facility in Pipestone, Minn., for U.S. blades. The cost of the retrofit program is estimated to be $25 million (USD)."

The above article appeared in Composites Technology and appears to answer the question about the US blade failures.
