SSE has awarded Senvion a contract to service its Gordonbush, Achany, Fairburn and Strathy North wind farms in Scotland.
Senvion will provide full service support for 107 of its MM82 turbines across the four projects.
The German manufacturer will carry out scheduled maintenance of the turbines and replace major components when required.
Senvion’s Inverness service centre, which played a crucial role in securing the contract with SSE, will be responsible for managing the contract.
SSE head of onshore wind Stuart Hood said: “We are pleased to have extended our partnership with Senvion which provides long term coverage and security to a significant proportion of our operational assets.”
Senvion managing director Europe North Knud Rissel said: “We are delighted to be awarded this historic service contract with SSE, one of our longest standing customers in the UK.
“By selecting us again, SSE have demonstrated their trust in our people, technology and customer service. The scale of the project also cements our position as one of the leading turbine service providers in the UK and our commitment to long term support for our customers.”
