How are battery energy storage costs forecasted?

Forecast procedures are described in the main body of this report. C&C or engineering, procurement, and construction (EPC) costs can be estimated using the footprint or total volume and weight of the battery energy storage system (BESS). For this report, volume was used as a proxy for these metrics.

What is the minimum power required for energy storage?

Objective: To compare cost and performance of various energy storage technologies. Minimum system power = 500 kW. DC system (two or more columns provided if you have two different systems on offer). Active heat exchanger (HEX)?

How much does energy storage cost?

Electricity Energy Storage Technology Options: A White Paper Primer on Applications, Costs and Benefits. EPRI-1020676, Final Report, December 2010, Electric Power Research Institute, Palo Alto, California. RedT Energy Storage. 2018. “Gen 2 machine pricing starting at $490/kWh.”

How much does a power system cost?

The same report predicted that C&C costs for the system would be between $150–$180/kW. In comparison, PowerTech Systems (2015) provided a cost estimate of only $183/kW for a 100-kWh system, of which only 50 kWh was considered usable.

Which battery energy storage technology has the lowest annualized value?

• On an annualized basis, Li-ion has the lowest total annualized $/kWh value of any of the battery energy storage technologies at $74/kWh, and ultracapacitors offer the lowest annualized $/kW value of the technologies included. An attempt was made to determine the cost breakdown among the various categories for PSH and CAES.

How do you calculate project costs for Li-ion battery technology?

To determine the total project costs for the Li-ion battery technology, for example, we take the product of the capital and C&C costs and its energy capacity (4,000*$372). We then add that value to the product of the PCS and BoP costs and the unit’s power capacity (1,000*$388).
