NMC battery storage cost vs benefit calculation in Vietnam

Why is battery energy storage important in Vietnam?

The Vietnam battery energy storage market has experienced significant growth due to the increasing adoption of renewable energy sources and the need for energy storage solutions. Battery energy storage systems (BESS) are critical for storing and managing electricity generated from renewables.

What are base year costs for utility-scale battery energy storage systems?

Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2022). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.

What is a battery energy storage system?

Battery energy storage systems (BESS) have a wide range of applications, from residential systems to large-scale utility projects that help with peak shaving, frequency regulation, and backup power. In areas where the grid is unreliable or inaccessible, batteries can provide backup power in case of outage or other emergency.

What is the storage capacity of a PV-battery system?

At the time of research, most of the papers studied PV-battery systems with storage capacities of 0.5–1 kWh times the installed PV capacity in kW, due to the high cost of such systems, meaning that batteries were used for short-term storage, normally less than one day.

Why is battery storage a burden for investors?

Nevertheless, battery life being shorter than the lifetime for PV modules, large investments, and no economic incentives make storage a burden for investors despite its tangible and intangible benefits alike.

Will storage futures lead to cost reductions in 2021?

The Storage Futures Study report (Augustine and Blair, 2021) indicates NREL, BloombergNEF (BNEF), and others anticipate the growth of the overall battery industry - across the consumer electronics sector, the transportation sector, and the electric utility sector - will lead to cost reductions in the long term.
