4 FAQs about Price Comparison of 40kWh Rural Power Distribution and Energy Storage Cabinets

Why do we use units of $/kWh?

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. 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).

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.

How much does a 300 MWh power plant cost?

Premium Scenario — 300 MWh, 6–8 hour duration, high-efficiency modules, advanced fire suppression, >1 interconnection point, complex civil works. Labor hours: 68,000; per-kWh price: $380–$520; Total: $114.0–$156.0 million. Assumptions: region, specs, labor hours.
