Yes, but it's at a local level.

One of the benefits of batteries is that they can be spread around and used to alleviate bottlenecks. Building transmission is very expensive, so this is a good early market for them.

These are called Non-Tranmissikn Alternatives or Non-Wires Alternatives:

NTAs are programs and technologies that complement and improve operation of existing transmission systems that individually or in combination defer or eliminate the need for upgrades to the transmission system.
