Abstract: A method for operating an ensemble of electric assets powered by a set S of rechargeable electric storage units is disclosed, said assets being configured to perform a primary purpose, unrelated to storage or provision of electric energy, in particular a transportation task, according to a pre-determined schedule, the method including the steps of
a) selecting, at a time to, based on the schedule, a first subset S 1 of the rechargeable electric storage units for providing ancillary grid services to a grid operator during an interval of time [ t 1 , t 2 ] in a future of to;
b) determining, based on properties of the subset S 1 , related to the ancillary services;
c) communicating said specifications to a grid operator;
d) during the interval of time [ t 1 , t 2 ], providing ancillary grid services in accordance with the specifications, wherein at least a second subset S 2 of rechargeable electric storage units, said second subset being a subset of the first subset S 1 , preferably being identical to the first subset, is used to store or supply electric energy, wherein
e) a state of health, in particular a remaining expected lifetime, for each electric storage unit of a third subset S 3 of electric storage units, preferably all rechargeable electric storage units, is taken into account in the selection in step a).
