A new academic study claims that batteries used in plug-in electric vehicles (PEVs) could be used to stabilise electrical grid networks, as well as for providing houses and businesses with backup power.

LG Chem and Siemens have announced the signing of a deal to “collaborate more closely” on grid-stabilising energy storage systems, which will include work on Siemens’ Siestorage solution for grid integration of renewable energy.

A large scale ‘battery park’ has gone online in West Meklenberg, Germany, designed to stabilise grid frequency in an area where a large amount of power generation comes from wind and other renewable energy.
