6 FAQs about [Depreciation methods for battery energy storage]
Can FEMP assess battery energy storage system performance?
This report describes development of an effort to assess Battery Energy Storage System (BESS) performance that the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP) and others can employ to evaluate performance of deployed BESS or solar photovoltaic (PV) +BESS systems.
How is energy storage capacity calculated?
The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
What are the KPIs of a battery system?
For battery systems, Efficiency and Demonstrated Capacity are the KPIs that can be determined from the meter data. Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out).
What is the maximum energy accumulated in a battery?
The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
How do you calculate battery efficiency?
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
Why do we need batteries?
Batteries allow the PV energy to be stored and discharged at a later time to displace a higher retail rate for electricity. Utilities are increasingly making use of rate schedules which shift cost from energy consumption to demand and fixed charges, time-of-use and seasonal rates. Batteries are increasingly being used to reduce utility costs by:
