Because the BESS has a limited lifespan and is the most expensive component in a microgrid, frequent replacement significantly increases a project''s operating costs. This paper
The life cycle capacity evaluation method for battery energy storage systems proposed in this paper has the advantages of easy data acquisition, low computational
Your 7MWH rating means that the battery will be out of energy after the product of multiplying the power times the time is running equals 7MWH. In your example it would theoretically run out of energy after running 1 hour, 40 minutes (7/4.2). So 7 MWH is how much energy (also termed "capacity") the battery contains.
Today, the installed capacity of battery energy storage systems operating in Europe has exceeded the 20GW mark, with the United Kingdom, Germany and Italy dominating the European energy storage market. However,

The main trade-off in battery development is between power and energy: batteries can be either high-power or high-energy, but not both.

Battery energy reflects how much electric energy the battery can provide to the outside world in actual use, and is an important indicator for evaluating the battery''s energy storage capacity. 3.
A key emerging market for stationary storage is the provision of peak capacity, as declining costs for battery storage have led to early deployments to serve peak energy demand [4].Much of the storage being installed for peaking capacity has 4 h of capacity based on regional rules that allow these devices to receive full resource adequacy credit [7].

The battery energy storage systems are used for power demand periods where the DGs are unable to supply the load for only some periods. Hence, BESS is small in size, and costs are reduced accordingly. However, the proper size of a BESS affects its longevity and maintenance or replacement costs.
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
Battery storage is a technology that enables power system operators and utilities to store energy for later use.
Understandably, the capacity of any storage will increase with the system size. The more battery stacks are installed, the more electric energy can be put in for storage. The larger the water reservoir, the greater energy turnaround becomes possible. The system size should be matched with the load and specific application.
Storage capacity is typically measured in units of energy: kilowatt-hours (kWh), megawatt-hours (MWh), or megajoules (MJ). You will typically see capacities specified for a particular facility with storage or as total installed capacities within an area or a country. A portable battery pack with a storage capacity of 450 Wh...
Firm Capacity, Capacity Credit, and Capacity Value are important concepts for understanding the potential contribution of utility-scale energy storage for meeting peak demand.
