Why stor­age?

With the steady expan­sion of renew­able ener­gies, the demands on the trans­mis­sion and dis­tri­bu­tion grids are increas­ing. Longer trans­mis­sion routes lead to high­er costs for the neces­sary grid expansion. 

Renew­able energy sources such as wind and sol­ar also place high­er demands on all parties involved to keep the elec­tri­city grids stable, i.e. to avoid over­loads as well as power outages.

Bat­tery stor­age sup­ports the grid 

We see decent­ral­ised elec­tri­city stor­age as the fourth pil­lar of energy sup­ply in the age of renew­able ener­gies, along­side the three famil­i­ar ones — gen­er­a­tion, trans­port and con­sump­tion. Bat­tery stor­age con­trib­utes sig­ni­fic­antly to the sta­bil­isa­tion of the elec­tri­city grids, as it can flex­ibly bal­ance loads and thus make or keep the elec­tri­city grid controllable.

Bat­tery stor­age reduces grid costs

At the same time, bat­tery stor­age sys­tems con­trib­ute to redu­cing grid costs, because they can be used loc­ally and replace grid capa­cit­ies when they are deployed over a wide area. They thus make an import­ant con­tri­bu­tion to the secur­ity of sup­ply of all elec­tri­city consumers.
