Energy storage battery project investment cost

Are battery storage projects financially viable?

Different countries have various schemes, like feed-in tariffs or grants, which can significantly impact the financial viability of battery storage projects. Market trends indicate a continuing decrease in the cost of battery storage, making it an increasingly viable option for both grid and off-grid applications.

Is battery storage a good investment?

The economics of battery storage is a complex and evolving field. The declining costs, combined with the potential for significant savings and favorable ROI, make battery storage an increasingly attractive option.

What are base year costs for utility-scale battery energy storage systems?

Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2022). 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.

Are battery storage costs based on long-term planning models?

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.

How has the cost of battery storage changed over the past decade?

The cost of battery storage systems has been declining significantly over the past decade. By the beginning of 2023 the price of lithium-ion batteries, which are widely used in energy storage, had fallen by about 89% since 2010.

When are battery cost projections updated?

In 2019, battery cost projections were updated based on publications that focused on utility-scale battery systems (Cole and Frazier 2019), with a 2020 update published a year later (Cole and Frazier 2020). This report updates those cost projections with data published in 2020 and early 2021.
