Windcluster & Haverigg FAQ's

When was the project built?

The original Haverigg I project was commissioned in August 1992. It was the second commercial wind energy project in the UK. It comprised five Vestas V27 wind turbines. These machines were replaced with four Vestas V52 turbines (Haverigg III), which commenced operation in February 2005.

What happened to the original turbines?

Three of them were sold to the Island Of Gigha ( where they have provided income for the community and are known as the Dancing Ladies.

What is the output of the project?

The Haverigg III turbines typically generate 10.3GWh per year, a capacity factor of 35%, amongst the highest for an onshore project in England. This output is sufficient for the electrical needs of around 2,600 homes. 

Who looks after the turbines?

Windcluster Ltd has a service agreement with the turbine manufacturer, Vestas Wind Systems A/S ( and also employs WPO ( to undertake overall site management.

What is the specification of the turbines?

The turbines at Haverigg are Vestas V52 machines. They are no longer in production, but Vestas maintain a full spares list.

What are the environmental benefits?

Using the BEIS figure for average UK emissions from electricity generation of 430g/kWh, Haverigg III saves 4,430 tonnes of CO2 per year, or put another way it offsets the carbon footprint of 443 people in the UK.


We are established a community fund and are currently supporting Haverigg Primary School.
