  Understanding energy transport in quantum systems is crucial for an
understanding of light-harvesting in nature, and for the creation of new
quantum technologies. Open quantum systems theory has been successfully applied
to predict the existence of environmental noise-assisted quantum transport
(ENAQT) as a widespread phenomenon occurring in biological and artificial
systems. That work has been primarily focused on several `canonical'
structures, from simple chains, rings and crystals of varying dimensions, to
well-studied light-harvesting complexes. Studying those particular systems has
produced specific assumptions about ENAQT, including the notion of a single,
ideal, range of environmental coupling rates that improve energy transport. In
this paper we show that a consistent subset of physically modelled transport
networks can have at least two ENAQT peaks in their steady state transport
efficiency.
