Cape Wind : Wind Turbines Need Update Before Project Starts

Cape Wind years ago proposed using 130 gear box driven wind turbines rated at 3.6 Megawatts.

The land based gear box driven turbines have been failing at an alarming rate of around 3 to 5 years.

The wind industry has changed to a direct drive type wind turbine as a result of the gear box failures.

What are the new type of turbines to be used instead of the old type turbines ?

Ocean Wind Turbines - Upgrades to make economical sense

Ocean Wind Project Already Old

The commercial land based wind industry in New England has had its share of turbine gear box failures. Land based turbine gear boxes have been failing at around three to five years at a cost of around one million per repair and again in another three to five years. Ocean wind turbines are double the cost. Every year improvements are made on the gear boxes and transmissions because of the history of the failures.

In March of 2010 the Nantucket ocean wind project announced it went into an agreement with a company to purchase 130 of its 3.6-Megawatt (MW) ocean wind turbines. Today three years later there is a new better rated 4.0-Megawatt ocean turbine that incorporates a higher rated gearbox and better generator cooling system.

It makes financial and economical sense to upgrade to the new better and bigger wind turbines.

The length of time to obtain permits could force a well intended investment into older type turbines and bypass the upgrades to expedite the permit process. Newer turbines have longer blades and hight. It's unclear if the introduction of a new wind turbine at this time would trigger another review of the project.
