An initial feasibility study is to be carried out at Callander Waste Water Treatment Works (WWTW) investigating how waste heat can be extracted and incorporated with thermal energy storage to be distributed to remote and off-gas grid areas.
Benefits of the initiative, known as the Callander Local Energy Opportunity (CLEO), include energy demand reduction; energy savings; added resilience and security of heat supply, and possible income generation through opportunities for community ownership models. Other opportunities for job creation and upskilling of local workers are also possible.
If successful, the project would be scalable and replicable across the Stirling Council area.
The joint application is receiving funding from the Scottish Government's Innovative Local Energy Systems (ILES) initiative. Supported by the European Regional Development Fund, the scheme is designed to accelerate the development and delivery of low-carbon infrastructure projects in smaller towns and settlements as well as remote, rural and off-gas grid communities.

Councillor Evelyn Tweed said: "Stirling Council has a large rural area, the majority of which show higher levels of fuel poverty than urban areas, due to lack of fuel choice as many are off the gas grid.
"The higher capacity of the Waste Water Treatment Works in Callander and size of the population made the region an ideal choice for the pilot scheme.
"With Council assets, including secondary and primary schools, plus a leisure centre, Callander can provide a successful concept project that would then be scalable and replicable across the area, to help alleviate fuel poverty and also to attract businesses to the area.
"This funding can help produce regeneration and economic development through reduced energy bills, as higher energy bills can be prohibitive to businesses setting up in rural areas."
Mari Davies, Scottish Water Horizons Project Manager, said: "We are delighted to receive funding to enable us to look at new ways of storing and delivering heat in the Callander area.
"Within our sewer network there is massive potential for heat to be harnessed as renewable energy source. The challenge for us now is how we store this heat and get it to local homes and businesses that need it most.
"Using thermal energy storage in combination with innovative waste water heat extraction technology, we can test the concept in an area that is typical of many rural and remote areas across Scotland. If successful, there is opportunity for wider roll-out, helping to alleviating fuel poverty, providing local employment and contributing to Scotland's circular economy."
