This project is innovative as it will consider options to make use of embedded wind turbines on the islands of Harris, Lewis, North Uist, South Uist and other islands forming part of the Western Isles located off the north west coast of Scotland.

The requirement for innovative commercial arrangements will be considered and identified as necessary as the operation of these non-SSEPD owned assets would assist and support operation in "island" mode.

The second aspect of the project relates to reducing diesel generation use and gaining increasing confidence in the contribution wind generation can make to supplying load to the islands in normal operating mode.In turn this will reduce the carbon emissions of the embedded diesel generation.

The potential for the application of the outputs from this study to other parts of the GB distribution network becomes greater as the amount of distributed renewable generation assets increases.

The study is to determine the potential to improve the resilience of supply to customers in the Western Isles and to reduce the use of diesel generation by including the output from embedded renewable generation.
The aim of this project is to determine the viability of options to enhance the operation of remote rural networks by using embedded renewable generation.

The delivery of a study which• Determines the viability of options to permit the operation of the network in island mode.• Determines the potential to utilize the increasing volume of wind generation on the islands and consequently to reduce the running hours of the embedded diesel generation plant.
