how to calculate the energy storage capacity of the state grid
UNDERSTANDING ENERGY CAPACITY AND CAPACITY FACTOR
The capacity factor is the ratio between what a generation unit is capable of generating at maximum output versus the unit''s actual generation output over a period of time. These two variables can be significantly different. Many generators do not operate at their full capacity all the time. A generator''s output may vary based on ...
