How are energy storage systems priced?
They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate. The power rating of an energy storage system impacts system pricing, where larger systems are typically lower in cost (on a $/kWh basis) than smaller ones due to volume purchasing, etc.
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 assumed 4-hour 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 2024 value such that each projection started with a value of 1 in 2024.
Why are battery system costs expressed in $/kWh?
By expressing battery system costs in $/kWh, we are deviating from other power generation technologies such as combustion turbines or solar photovoltaic plants where capital costs are usually expressed as $/kW. We use the units of $/kWh because that is the most common way that battery system costs have been expressed in published material to date.
What are the costs of energy generation?
These expenses may include water consumption, waste and wastewater discharge, chemicals such as selective catalytic reduction ammonia, and consumables including lubricants and calibration gas. Because these costs are generation dependent, the values are levelized by the cost per unit of energy generation and presented in $/MWh.
