NINES is expected to provide a step-change improvement to the whole energy system in Shetland – providing cleaner, more efficient electricity production and a better quality of supply, all at the least possible cost for customers. This improvement will be achieved by implementing new technology solutions that will fundamentally change the way the current energy infrastructure is managed – a true “smart grid”.

Targeted improvements are:

  • Decrease the overall requirement for generation from Lerwick Power Station thus lowering fuel, operation and maintenances costs
  • Reduce 2010 energy peak demand by 20MW, therefore saving on plant replacement costs
  • Facilitate and increase renewable energy connections, thus reducing C02 emissions and air pollution
  • Efficient utilisation of new energy storage technologies to ensure renewable energy can be exported when it is produced and manage short term fluctuations in demand for electricity that affect network efficiency and quality of supply

Fundamental to the optimisation of the electricity network and the contributing technologies will be modelling work undertaken by the University of Strathclyde. This will provide a clear picture of Shetland’s energy system that will need to answer such questions as:

  • How can a distribution system operate securely with a high penetration of renewable generation?
  • What is the economic impact on industry participants?
  • What is the impact of a low carbon network on domestic and industrial customers?
