The ambitious target of reaching net-zero greenhouse gas emissions by 2050 in the UK, which includes decarbonisation heat and electricity, means increase instantaneous power from non-dispatchable renewable energy sources (RESs). intermittency RESs will cause stability issues for grid resulting mismatch between generation RES load demand. Battery storage systems (BESS) can match loads with provide flexibility to grid. This study is proposing health sector as a new services provider through BESS. has large that run throughout year, managing this it Four different scenarios have been evaluated range behind-the-meter (BTM) BESS hospital UK arbitrage ancillary considering option installing photovoltaic (PV) system. It was found would not be economically viable alone since payback period always greater than lifetime. However, bundling participating market resulted periods low 3.10 years some systems, net present value (NPV) could reach more £5 million. work provides evidence significant player transition renewables-led system, an exemplar other sectors, one solutions recovery COVID19 pandemic.
