This can be compared to the output of a power plant. Energy storage capacity is measured in megawatt-hours (MWh) or kilowatt-hours (kWh). Duration: The length of time that a battery can be discharged at its power rating until the battery must be recharged.
For example, a 10 MWh battery can supply 10,000 KWh of energy within a specific time period. It is used to accurately determine the capacity of energy storage needed for various applications such as electric vehicle batteries and grid storage solutions.
When thinking about energy storage duration, it's important to understand that this is just the time period over which the storage system can deliver energy at its full power rating. Consider a two-hour and four-hour battery with the same storage capacity in MWh, say 8 MWh.
• 0.25C Rate: At a 0.25C rate, the battery charges or discharges over four hours. In this scenario, a 10 MWh BESS would deliver 2.5 MW of power for four hours. This slower rate is beneficial for long-duration energy storage applications, such as storing excess renewable energy generated during off-peak times for use when demand is higher.
Duration = 40 MWh / 10 MW = 4 hours This means that if the battery is fully charged, and discharged at its maximum power rating, it will provide energy for four hours before needing a recharge. Of course, if it is discharged at less than its maximum rating, it could provide energy for a longer period of time.
