6 FAQs about [Energy storage line function]
How does energy storage work?
Instead of curtailing this excess energy, it is stored in ESS. Later, during peak demand periods when electricity prices rise, the stored energy can be discharged to meet the higher demand or sold back to the grid at a premium, generating profits for utilities or grid operators.
