Integrated energy systems can benefit substantially from flexibility provision in their operations. This paper explores the operational cost optimisation of a UK public facility dedicated to health services by harnessing the flexibility gained from available gas and electricity grid inputs, a combined heat and power unit, and integration of thermal and electrical energy storage units into the local network. The optimisation algorithm assists in the sizing of the storage units under different cases of fuel price and energy storage efficiency. Optimal integration of energy storage results in operational cost savings of £7.6/day under normal operating conditions and of £64.7/day for an elevated gas price. The findings are based on real-time energy price and demand profiles and reveal that the local energy system benefits more from the thermal stores than from electrical energy storage.
