MW scale storage system EPC turnkey quotation per 50kW 2030

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 much does EPC cost?

EPC included in 50% markup and 25% installation. Project development included in 50% markup and 25% installation. Grid integration including transformers, meters, safety disconnects, and nominal labor costs added at $19.89/kW, same as for 100 MW lithium-ion battery system.

How many MW is a battery energy storage system?

For battery energy storage systems (BESS), the analysis was done for systems with rated power of 1, 10, and 100 megawatts (MW), with duration of 2, 4, 6, 8, and 10 hours. For PSH, 100 and 1,000 MW systems at 4- and 10-hour durations were considered. For CAES, in addition to these power and duration levels, 10,000 MW was also considered.

Is grid-scale energy storage a viable alternative to electric vehicles?

Grid-scale energy storage, however, lacks the stringent power and weight constraints of electric vehicles, enabling a multitude of storage technologies to compete to provide current and emerging grid flexibility services.

How do you convert kWh costs to kW costs?

The $/kWh costs we report can be converted to $/kW costs simply by multiplying by the duration (e.g., a $300/kWh, 4-hour battery would have a power capacity cost of $1200/kW). To develop cost projections, storage costs were normalized to their 2022 value such that each projection started with a value of 1 in 2022.

How much does a MWh of electricity cost?

The average $/MWh for generation power in the 41-100% range corresponds to $1.71/MWh, while the average for compression was found to be $0.39/MWh. For every 1 MWh generated, only 0.56 MWh of electricity is needed for compression on average (Farley, 2020b) so the charging maintenance O&M is $0.22/MWh generated.
