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 14.5 MW based at the Peak Load Boiler Station. 

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. 

SHEAP connected to Lerwick Power Station in 2022 in order to use surplus heat to supplement the district heating scheme.

We are currently investigating other potential heat sources.
