SSE will be transporting two grid transformers on the final leg of their journey to the 443MW Viking Energy Wind Farm on Shetland on 26 June.
A police-escorted convoy of two grid transformers will occur between the Port of Lerwick and the wind farm’s construction site.
It will travel along the A970 road to arrive at the new access road at Sandwater in the early hours of 27 June.
The transformers will make up part of the new substation for the wind farm.
Two remaining transformers are expected to be delivered to the construction site in early August.
Stakeholder manager for Viking Aaron Priest said: “These transformers are critical items for the substation operation. Due to their scale, they require a police escort to move them from Lerwick Port on to site.
“In advance, we’d like to thank drivers and residents for their patience while the delivery takes place.
“Public safety is paramount and in co-operation with Police Scotland, our team will do their very best to keep any disruption to a minimum.”
The transformers started their journey in Linz, Austria.
Each has an approximate delivery weight of 94 tonnes.
