This paper considers the optimal dispatch of energy-constrained heterogeneous storage units to maximise securityof supply. A policy, requiring no knowledge of the future, ispresented and shown to minimise unserved energy during supply-shortfall events, regardless of the supply and demand profiles.It is accompanied by a graphical means to rapidly determineunavoidable energy shortfalls, which can then be used to comparedifferent device fleets. The policy is well-suited for use within theframework of system adequacy assessment; for this purpose, adiscrete time optimal policy is conceived, in both analytic andalgorithmic forms, such that these results can be applied todiscrete time systems and simulation studies. This is exemplifiedvia a generation adequacy study of the British system.
