Opti­miz­ing the “Ener­gy Sys­tem City”: DELTA real laboratory

The Darm­stadt Ener­gy Lab­o­ra­to­ry for Tech­nolo­gies in Appli­ca­tion (DELTA) acts as a show­case for the urban ener­gy tran­si­tion to demon­strate inter­act­ing ener­gy-opti­mised neigh­bour­hoods. The DELTA real lab­o­ra­to­ry is intend­ed to demon­strate that the tech­ni­cal­ly proven poten­tial for increas­ing the ener­gy effi­cien­cy and flex­i­bil­i­ty of urban quar­ters is eco­nom­i­cal­ly fea­si­ble and that this poten­tial is also accept­ed by soci­ety. To this end, meth­ods are to be test­ed and fur­ther devel­oped in order to bring suc­cess­ful tech­ni­cal pilot projects into wide­spread use. For this pur­pose, the devel­op­ment of inno­v­a­tive (coop­er­a­tive) busi­ness mod­els is ele­men­tary in order to be able to oper­ate the emerg­ing ener­gy sys­tem with­out sub­si­dies on the one hand and to allow all stake­hold­ers of the ener­gy sys­tem to par­tic­i­pate in the ener­getic and eco­nom­ic poten­tials on the oth­er hand.

With­in the project, a mul­ti-lay­ered, cross-sec­toral approach is being pur­sued. The focus here is on con­sis­tent­ly increas­ing the ener­gy effi­cien­cy of all sec­tors, which is already seen today as the great­est usable poten­tial of the ener­gy tran­si­tion. Fur­ther­more, poten­tials for shift­ing elec­tri­cal loads over time are to be iden­ti­fied and used to opti­mize the urban elec­tric­i­ty sys­tem and to make opti­mal use of renew­able ener­gy sources. Both are achieved by intel­li­gent­ly link­ing indi­vid­ual quar­ters of the urban ener­gy sys­tem under con­sid­er­a­tion and by sec­tor cou­pling. To this end, it is planned to involve all rel­e­vant stake­hold­ers, who will work out prac­ti­ca­ble solu­tions in tried and test­ed dia­logue formats.
