Additions to the Scheme
In 2006 a hot water storage tank was installed to store excess heat during off-peak periods and provide heat during peak loads. This allowed for the equivalent of a further 500 properties to be connected without the need for a further heat source. Another 6.5 MW boiler was installed in 2008 to give a total back up capacity of 15 MW based at the Peak Load Boiler Station. Using customers former boilers as additional back-ups, there is a further 6 MW of boiler capacity spread around Lerwick.
During 2007/08 a radio transmitting system was installed to collect customer meter readings which are transmitted directly to our office on demand.
The scheme has proved to be very popular and all the heat produced is currently used. During colder periods of weather we have to burn oil to provide the necessary heat and for this reason we are unable to connect any new properties.
We are currently investigating other potential heat sources.
