Prema podacima iz NREAP-a, do 2008. godine, Bugarska je već u potpunosti iskorištavala svoj postojeći hidroenergetski potencijal, a koristio se samo dio njenog potencijala čvrste biomase, primarno za grijanje u domaćinstvima i javnim zgradama.
By 2008, Bulgaria was already utilising in full its existing hydro power potential, while only a portion of its solid biomass potential was being used, primarily for heating in households and in public buildings, according to the NREAP.
