Keeping the Lights on in Knoydart Scotland
Knoydart is situated between Loch Nevis and Loch Hourn on the west coast of Scotland and relies exclusively on locally-generated power because it is not connected to the National Grid.
In recent years, the community has faced repeated instances of power outages, particularly in periods of high demand, such as the holiday season around Christmas and New Year. But all that has changed with the upgrading of the local hydro-power generation system and the design and installation of Energy Assets’ Z-Lynk demand management technology.
The Z-Lynk system monitors mains frequency and power demand continuously across the Knoydart network. When the hydro system comes close to its maximum threshold, Z-Lynk sends command signals via a low power transmitter to receivers installed on domestic storage heaters to instigate progressive and automatic load switching to keep the supply balanced. The system also monitors the cumulative amount of time each load is shed, ensuring that switching is evened-out across several loads of equal priority so that no single home is discriminated against.
Knoydart now has a demand management system in place, along with greater generation capacity, to ensure that the lights stay…even during popular tourist periods. It is also supporting the community’s growth plans for the future.
As soon as the smart switches were installed, everything worked perfectly
