Energy Storage for a Decarbonizing Grid (Part 1): What is it?

  1. Operating Reserves — BESS can be used to provide back-up power to the whole grid in the event of plant outages or natural disasters
  2. Frequency regulation — BESS can be used to smooth energy supply/demand imbalances that change the frequency (hertz) of electricity moving through transmission lines
  3. Inertia — BESS can be used to harmonize the frequency of the grid in certain difficult-to-access locations
  4. Voltage Control — Frequency regulation for back-up generators
  5. Black Start — Batteries can be used to jump-start natural gas plants
