We investigate multichromophoric energy transfer allowing for bath-induced fluctuations at different sites to be correlated. As a prototype system we consider a light-harvesting antenna surrounding a reaction center. We show that the interplay between quantum coherence and correlated fluctuations can generate a room temperature transfer process featuring a marked dependence on the degree of symmetry and delocalization of the initial exciton state. Our work illustrates how these quantum features could support fine tuning of energy transfer efficiencies in closely-packed natural and artificial light-harvesting complexes
