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.

Are battery storage costs based on long-term planning models?

Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.

What is a behind-the-meter battery storage system?

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.

How do you calculate battery power versus energy 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) For more information on the power versus energy cost breakdown, see (Cole and Frazier, 2020). For items included in CAPEX, see the table below.
