The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations. In September 2021, DOE launched the Long-Duration Storage Shot which aims to reduce costs by 90% in storage systems that deliver over 10 hours of duration within one decade. The analysis of longer duration storage systems supports this effort.

Dependence on the main grid: Grid-connected systems still rely on the main grid as their primary source of power. They need to draw electricity from the grid to operate, so they can''t operate autonomously during grid outages. 2. One-way power flow: Grid-connected systems typically have a one-way power flow, where electricity flows …
