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.

How do I calculate the cost of a battery system?

Within the ATB Data spreadsheet, costs are separated into energy and power cost estimates, which allows capital costs to be constructed for durations other than 4 hours according to the following equation: Total System Cost ($/kW) = [Battery Pack Cost ($/kWh) × Battery Energy Capacity (kWh) + Battery Power Capacity (kW) × BOS Cost ($/kW) +

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.

What is the difference between battery capacity and E/P?

Battery capacity is in kW DC. E/P is battery energy to power ratio and is synonymous with storage duration in hours. We also consider the installation of commercial BESS systems at varying levels of duration (Figure 1). Costs come from NREL’s bottom-up PV cost model (Ramasamy et al., 2022).

How do you calculate a battery pack cost?

Total System Cost ($/kW) = [Battery Pack Cost ($/kWh) × Battery Energy Capacity (kWh) + Battery Power Capacity (kW) × BOS Cost ($/kW) + Battery Power Constant ($)] / Battery Power Capacity (kW)

Are battery cost and performance projections based on a literature review?

Battery cost and performance projections in the 2024 ATB are based on a literature review of 16 sources published in 2022 and 2023, as described by Cole and Karmakar (Cole and Karmakar, 2023). Three projections for 2022 to 2050 are developed for scenario modeling based on this literature.
