Electrification of heat is a key element of the UK’s decarbonisation strategy, however it risks significantly increasing network peak demand. Thermal energy storage (TES) provides an opportunity to introduce flexibility into the system and allow load to be shifted to off-peak periods, delivering a range of benefits in the decarbonised electricity system. This paper quantifies system-wide benefits of installing heat batteries alongside residential heat pump systems, using a whole-electricity system model. System value for a high uptake of TES is found to be between £1.5-1.7bn/in 2035 and £1.1-2.3bn/yr in 2050. Most of the system value is derived from savings in generation investment cost and reduced distribution network cost. Customer-level benefits in the long term are estimated at between £200 and £300 per customer annually, with highest values observed at low TES uptake levels (10%).
