New study: Net­worked neigh­bor­hoods sup­ply them­selves with ener­gy opti­mal­ly and inexpensively

A neigh­bor­hood-opti­mized approach to ener­gy sup­ply for neigh­bor­hoods offers many advan­tages over decen­tral­ly opti­mized sup­ply struc­tures at the build­ing lev­el. This is the result of the study “Mod­el­ing of sec­tor-inte­grat­ed ener­gy sup­ply in the neigh­bor­hood”. The study was pre­pared by the Fraun­hofer Insti­tute for Solar Ener­gy Sys­tems ISE on behalf of dena.

Mod­el cal­cu­la­tions based on sev­er­al dif­fer­ent types of neigh­bor­hoods — exist­ing and new build­ings with dif­fer­ent types of use in urban and rur­al areas — have shown that neigh­bor­hood-opti­mized sup­ply has cost advan­tages of around 30 to 45 per­cent com­pared with sup­ply to indi­vid­ual buildings.

The study con­tin­ues to empha­size the ben­e­fits that open pow­er exchange between build­ings in a neigh­bor­hood would have. At the same time, an analy­sis of the cur­rent legal frame­work shows that the valid legal frame­work does not allow local actors to estab­lish sup­ply struc­tures at the neigh­bor­hood lev­el that enable such a low-thresh­old exchange of ener­gy between actors in the neighborhood.
