Based on cycling requirements, three applications are most suitable for second-life EV batteries: providing reserve energy capacity to maintain a utility’s power reliability at lower cost by displacing more expensive and less efficient assets (for instance, old combined-cycle gas turbines), deferring transmission and distribution investments, and taking advantage of power-arbitrage opportunities by storing renewable power for use during periods of scarcity, thus providing greater grid flexibility and firming to the grid.

IRENA is tracking the current costs and performance of BESS and is monitoring how the value of these systems in different applications and international markets is likely to evolve over time with increasing self-consumption of rooftop solar PV, the provision of grid services such as frequency regulation or ramping needs, as well as peak power demand shaving in industry and alike.

Definition: LFP 48V solar batteries refer to battery modules used in energy storage systems, which typically consist of 15 or 16 3.2V lithium iron phosphate (LFePO4) batteries connected together to form a system with a total voltage of 48 volts or 51.2 volts. 48V (51.2V) systems are commonly used in residential and commercial and industrial solar energy systems due to their higher voltage and relatively low current requirements, which reduces heat loss due to high current products and improves system efficiency.
