What to know about energy storage

Electrical grid operators need to match energy supply and demand at a moment’s notice. Energy storage enables the efficient delivery of reliable power from clean energy sources when people need it most – even during extreme weather or other events that stress the grid.

How Energy Storage Works

  1. 1 Electricity is generated.
  2. 2 Electricity is stored in energy storage.
  3. 3 Electricity is discharged from storage when demand is high and supply is low.
  4. 4 Transformer increases voltage of electricity.
  5. 5 Electricity travels through transmission lines.
  6. 6 Transformer decreases voltage of electricity.
  7. 7 Electricity travels through collection lines.
  8. 8 Electricity is delivered to customers.
