What is a bottom-up Bess model?

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. Using the detailed NREL cost models for LIB, we develop base year costs for a 60-megawatt (MW) BESS with storage durations of 2, 4, 6, 8, and 10 hours, (Cole and Karmakar, 2023).

Can Bess costs be calculated for a storage duration?

The (Cole et al., 2021) projections contain information for both power and duration, so costs can be calculated for any storage duration; however, they do not account for how different BESS component costs (particularly, the LIB pack cost) change over time (Cole et al., 2021) .

Which Bess CAPEX paths are used in sensitivity analysis?

Three BESS CAPEX paths are used in the analysis of this study. CAPEX Path 1 is representative of predicted decline, while CAPEX Paths 2 and 3 are for sensitivity analysis. (5.3)

What is the maximum value of Bess capacity at year 14?

The maximum value of BESS capacity at year 14 is 171 MWh. Scenario 4 has a project value of €0.93 M. Similar to scenario 2 and 3, compensating for degraded BESS capacity is not fulfilled from year 15 to 20.

How much money will CAPEX invest in energy storage?

CAPEX investment in the United States FTM and C&I BESS markets alone is poised to be a cumulative USD 23.6 billion until 2025. Adding more than 25 GW in the same timeframe and 55 GW across the whole energy storage industry through 2030.

What is the baseline function in a BESS project?

The baseline function V ( Eq. (20)) from the operational model gives the daily expected revenue for a Battery Energy Storage System (BESS) when it is 1. This baseline function is inputted into the planning model objective function to give the yearly revenue.
