The flywheel size (4-foot/1.2m diameter) is perfectly optimized to fit a cluster of 10 units inside a 20-foot container. Cables run from each flywheel unit to the associated power electronics rack. Power Electronics racks are stored in an electrical cabinet. A DC bus of 585-715V links the units (650V nominal).
The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power.
