The Coleraine Microgrid project, led by Ulster University, delivered a comprehensive feasibility study for a smart district energy network in Coleraine. The study focused on integrating large-scale water source heat pumps (WSHPs) and electrode boilers to serve industrial and public sector heat consumers, while also providing grid services like frequency regulation and reserve capacity.
The project developed a detailed energy model which explored the viability of a hybrid power-to-heat system and identified and quantified the year-round heat demand at UU’s Coleraine campus and surrounding industrial area. This information was used to develop a technical concept for a district energy network using heat extraction from the River Bann and compressed air energy storage. The simulation results showed a significant potential for cost savings and carbon reduction.
The project catalysed interest in replicating district energy schemes in other areas of Northern Ireland including Antrim, Ballymena, Larne and Belfast. Industrial partners gained tools to showcase their technologies, while energy consumers received actionable insights into network integration. CASE’s involvement was pivotal in the formation of the consortium and overcoming market inertia, positioning Coleraine as a model for smart energy infrastructure in Northern Ireland.
