This article explores the types of energy storage systems, their efficacy and utilization at different durations, and other practical considerations in relying on battery
In the context of a Battery Energy Storage System (BESS), MW (megawatts) and MWh (megawatt-hours) are two crucial specifications that describe different aspects of the system's performance. Understanding the difference between these two units is key to comprehending the capabilities and limitations of a BESS. 1.
In energy storage systems, MW indicates instantaneous charging/discharging capability. Example: A 1 MW system can charge/discharge 1,000 kWh (1 MWh) per hour, determining its ability to handle short-term high-power demands, such as grid frequency regulation or sudden load responses. 2. MWh (Megawatt-hour) – The “Endurance” of Energy Storage Systems
Energy Capacity (MWh) indicates the total amount of energy a BESS can store and subsequently deliver over time. It defines the duration for which the system can supply power before recharging is necessary. For instance, a BESS with an energy capacity of 20 MWh can provide 10 MW of power continuously for 2 hours (since 10 MW × 2 hours = 20 MWh).
1 MWh = 1,000 kWh (i.e., 1,000 kilowatt-hours). The MWh value of a system reflects its total energy storage capacity. Example: A 2 MWh battery can store 2,000 kWh of energy. If discharged at 1 MW, it can operate for 2 hours. Case Study: The 0.5 MW/2 MWh commercial and industrial energy storage system at EITAI’s Guangzhou facility.
Power Capacity (MW) refers to the maximum rate at which a BESS can charge or discharge electricity. It determines how quickly the system can respond to fluctuations in energy demand or supply. For example, a BESS rated at 10 MW can deliver or absorb up to 10 megawatts of power instantaneously.
MWh is a unit of energy, representing the cumulative product of power and time. 1 MWh = 1,000 kWh (i.e., 1,000 kilowatt-hours). The MWh value of a system reflects its total energy storage capacity. Example: A 2 MWh battery can store 2,000 kWh of energy. If discharged at 1 MW, it can operate for 2 hours.
