Small harbours can be intensive consumers of energy. A fishing port like Scalloway, situated on the Shetland islands in the northern part of the North Sea, consumes around 1.8 GWh per year, and produces CO2 emissions of around 1350 ton per year. There are thousends of harbours like this in the North Sea Region. The Scalloway showcase demonstrated, that even the low-hanging fruits of energy saving and improved energy efficiency have not been picked yet. A related study in the Scottish fishing port of Fraserburgh reached the same conclusions.
Even small fishing ports have got cold stores and an ice plant. These could in theory be used as providers of flexible load for intelligent demand side management. The local grid is in many cases not able to accommodate more wind turbines or other intermittent resources. It is clear that the Shetlands could profit mightily from the development of a local smart energy system, but in practice the islands still seem far removed from that goal. The showcases in Scalloway and Fraserburgh therefore have focused on raising the energy awareness among harbour stakeholders, by investigating the chances to raise energy efficiency, training and advising the end users.
