Deploying storage as transmission — "a relatively simple, but not widely-known concept" – offers networks new flexibility to meet capacity needs, the white paper argues. The basic idea is that energy storage is placed along a transmission line and operated to inject or absorb power, mimicking transmission line flows.

Transmission, distribution, and the clean energy transition

However, without a corresponding increase in its transmission network and no adequate storage facility, a significant amount of energy sourced from renewables is wasted due to curtailment. For instance, for the period of Jan-May 2019, an aggregate of 630,864 MWh of wind and solar generation was curtailed in California, a 2.19 times increase on

How It Works: Electric Transmission

Although most power flowing on the transmission and distribution grid originates at large power generators, power is sometimes also supplied back to the grid by end users via Distributed Energy Resources (DER)— small, modular, energy generation and storage technologies that provide electric capacity at end-user sites (e.g., rooftop solar panels).
