Transmission and distribution (T&D) networks are the backbone of today’s electricity systems.
T&D networks ability to work continuously and reliably is key to modern society; however, this ability is being put to the test as grids evolve to more distributed, low-carbon models. T&D networks were designed to move electricity from large generation centres to thousands or millions of end users.
In the new energy paradigm, these end users can produce and store electricity as well as using it, and the large generation centres are replaced with numerous, distributed resources. This change in function is stressing T&D networks in a variety of ways, for example by affecting the quality of power supplies and by creating congestion on parts of the grid.
As it turns out, many of these issues can be addressed through grid-scale battery storage.
This guide aims to provide a brief overview of battery storage applications and considerations in a T&D setting.
