Offshore wind turbines are now 9 MW

Offshore wind turbines are now much larger than their onshore equivalents having undergone rapid technological development in the last few years. Their generating capacity is now at 9 MW for the largest models, three times that of two or three years ago. This has in turn led to lower costs, particularly marine civil engineering costs. Lower costs of installation means that the cost of producing electricity from these machines is lower, leading to a lower cost of electricity overall. This link describes some of the larger offshore wind turbines available in the market. One of these, the Vestas V164, holds the world record for the most electricity produced by one wind turbine in a 24 hour period. This record production of 216,000 kWh in 24 hours is equivalent to 15 years of electricity for one Irish household.
