Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
Figure ES-2 shows the overall capital cost for a 4-hour battery system based on those projections, with storage costs of $245/kWh, $326/kWh, and $403/kWh in 2030 and $159/kWh, $226/kWh, and $348/kWh in 2050.
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.
In 2019, battery cost projections were updated based on publications that focused on utility-scale battery systems (Cole and Frazier 2019), with updates published in 2020 (Cole and Frazier 2020) and 2021 (Cole, Frazier, and Augustine 2021). There was no update published in 2022.
For those who already have solar panels or are considering a full solar power setup, investing in a 10kW battery storage system can significantly enhance energy performance and long-term value. What Is a 10kW Solar Battery? A 10kW solar battery refers to an energy storage system capable of delivering 10 kilowatts of power output.
The average 10kW solar battery price in Australia ranges from $10,000 to $18,000 fully installed in 2025, depending on the brand, inverter type, installation complexity, and available government rebates. This cost typically includes the battery unit, hybrid inverter, battery management system and professional installation.
