To Understand Energy Storage, You Must Understand ELCC
Currently most grid operators don''t actually calculate the capacity contribution of energy storage. They just have generic rules that determine storage''s capacity contribution based on its duration. For example, 4-hour energy storage will actually have different ELCC values in different parts of the country just because the grid
