We investigate the counting statistics of non-thermal equilibrium, or rare, quantum jump trajectories associated to Markovian exciton transport. By applying the large deviation theory to open quantum system dynamics, we are able to uncover dynamical transitions, or crossovers, in the statistics of such rare trajectories. We find that the crossovers are activated by electronic coherences, and occur in systems with a minimum of three interacting molecules. The formalism thus reveals subtle consequences of non- equilibrium thermal fluctuations on the steady-state statistics of systems exhibiting Markovian transport.
