Introduction: The battery will be used to provide back up power should a diesel generator on Shetlands Network trip or fail. It will also be used to allow the diesel generators on the grid to be run in their most efficient state by providing any power required for an increased load. Furthermore, the battery will be used to store any excess generation that is injected into Shetlands grid. In doing so, the battery will allow the diesel generators to remain at their efficient generation level until it has fully charged.

By assessing how the battery interacts with the network will allow us to determine how best to utilise the technology and whether we can use it to allow more energy production via renewables to be connected to the grid.

Objectives: The project seeks to implement an Active Network Management (ANM) scheme incorporating the integration of demand side management with an energy storage device. The primary objective is to use the energy storage device to manage demand and hence remove the need for traditional plant upgrades. It will build on three areas of development that have previously been successfully deployed, namely:

• Progress the successful ANM technology trialled on the Orkney Islands

• Add UK learning on grid scale battery storage technology to add to the current body of knowledge on energy storage

• Extend current large industrial customer demand side management to smaller industrial & commercial customers.
