Energy storage lithium battery cost budget

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

Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). 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 the bottom-up cost model for battery energy storage systems?

Current 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 (Feldman et al., 2021). The bottom-up BESS model accounts for major components, including the LIB pack, inverter, and the balance of system (BOS) needed for the installation.

How much does a non-battery energy storage system cost?

Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.

How much does battery storage cost?

The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. We use the recent publications to create low, mid, and high cost projections. Projected storage costs are $245/kWh, $326/kWh, and $403/kWh in 2030 and $159/kWh, $226/kWh, and $348/kWh in 2050.

How much does gravity based energy storage cost?

Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours. Li-ion LFP offers the lowest installed cost ($/kWh) for battery systems across many of the power capacity and energy duration combinations.

Do battery storage technologies use financial assumptions?

The battery storage technologies do not calculate levelized cost of energy (LCOE) or levelized cost of storage (LCOS) and so do not use financial assumptions. Therefore, all parameters are the same for the research and development (R&D) and Markets & Policies Financials cases.
