Energy or usage reflects demand or capacity multiplied by the amount of time that demand or capacity is in use. For instance, a 15-watt light bulb used for 2 hours creates 15 watts X 2 hours = 30 watt-hours of usage. Energy and usage are commonly measured in the following units:
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.
It 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.
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).
It can be compared to the nameplate rating of a power plant. Power capacity or rating is measured in megawatts (MW) for larger grid-scale projects and kilowatts (kw) for customer-owned installations. Energy storage capacity: The amount of energy that can be discharged by the battery before it must be recharged.
Rated Energy Storage Capacity is the total amount of stored energy in kilowatt-hours (KWh) or megawatt-hours (MWh). Capacity expressed in ampere-hours (100Ah@12V for example). The amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity.
Use case: A recent New York study proposed adding a 200 MW/200 MWh storage as a transmission asset instead of a new 345 kV tie line to help increase the power transfer capability and reduce congestion. Its estimated cost would be US$120 million, compared to the US$700 million capital cost for a wire-based solution.
Energy or usage reflects demand or capacity multiplied by the amount of time that demand or capacity is in use. For instance, a 15-watt light bulb used for 2 hours creates 15 watts X 2 hours = 30 watt-hours of usage. Energy and usage are commonly measured in the following units:

That''s why solar farms incorporate large pieces of equipment, called inverters, that convert DC to AC so the electricity the farm generates is usable by homes and businesses. Some energy is lost in that conversion–generally between 15% to 20%. So, a solar farm with a capacity of 100 MW of direct current (100 MWdc) generates roughly 80-85 MWac.
