A 225kW medium sized wind turbine suitable for powering larger farms, community projects and commercial properties.
PERFORMANCE
The energy capture of the Vestas V27 turbine is exceptionally good across a wide range of wind speeds and comes installed on a 31m free-standing tower for maximum energy capture.
RELIABILITY
The Vestas V27 turbine is intended for a range of harsh conditions, especially exposed locations.The remaining design life of these machines is in excess of 20 years.

At a particular location, the wind speed will vary about an annual mean value. The expected energy yields for the Vestas V27 at various annual wind speeds (AMWS) is shown below:
| AMWS m/s | Annual MWh | Daily kWh |
| 4 | 128 | 351 |
| 5 | 255 | 699 |
| 6 | 411 | 1126 |
| 7 | 575 | 1575 |
| 8 | 734 | 2011 |
| 9 | 878 | 2405 |
Note: The annual electricity consumption of a medium size home is in the region of 4- 6MWh or 11-16 kWh per day. At 6 m/s wind speed the Vestas V27 can provide the annual energy needs for 100 homes.
