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 a 4 MWh battery storage system?4 MWh BESS includes 16 Lithium Iron Phosphate (LFP) battery storage racks arrangedRated power2 MWin a two-module containerized architecture; racks are coupled inside a DC combiner panel.

What are the KPIs of a solar PV system?The computer model used was the National Renewable Energy Laboratory’s (NREL’s) System Advisor Model (SAM). The KPIs reported are Availability (% up-time) and Performance Ratio (PR). If the PV system output was zero or less than 5% of the model estimate, then the time interval was counted as “unavailable.
