How batteries could replace the need for some backup transmission lines

Utilities in US are testing batteries and other “non-wires alternatives” to power lines for bolstering grid resilience: Grid resilience projects have typically focused on adding power lines and connections so that if one line goes down, another can still deliver power. A newer approach known as “non-wires alternatives” looks to add redundancy instead with a mix of energy storage, microgrids or distributed generation.

The goal of these types of projects is to provide resiliency at a lower cost and reduce congestion, especially during hot summer months when the power grid is taxed from large numbers of customers running air conditioning units all at once.
