Around 2.1GWh of battery storage had been installed in Germany by the end of 2019, in households, at commercial and industrial (C&I) facilities and at large-scale in grid-connected applications.

Energy storage could solve problems of reliability for grid operators in India, such as the electricity blackout which struck Mumbai last month, a panel at the India Energy Storage Week conference heard today.

Not only can energy storage be used to “mimic” the roles of existing assets in the electricity network, a gigawatt-scale initiative in Germany shows how ways of thinking about energy storage could save transmission and networks “billions of dollars”, the COO of Fluence has said.
