Will additional storage technologies be added?

Additional storage technologies will be added as representative cost and performance metrics are verified. The interactive figure below presents results on the total installed ESS cost ranges by technology, year, power capacity (MW), and duration (hr).

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.

What is the energy storage Grand Challenge?

The U.S. Department of Energy’s (DOE) Energy Storage Grand Challenge is a comprehensive program that seeks to accelerate the development, commercialization, and utilization of next-generation energy storage technologies.

What factors add costs to a project?

Operation and maintenance (O&M) costs. And the time taken for projects to progress from construction to commercial operations. Other variables add costs to projects. For the sake of simplification, this survey covers capital expenditure (CAPEX) costs. For example, some costs that aren’t covered in this analysis include:

How much does a battery project cost?

Developer premiums and development expenses - depending on the project's attractiveness, these can range from £50k/MW to £100k/MW. Financing and transaction costs - at current interest rates, these can be around 20% of total project costs. 68% of battery project costs range between £400k/MW and £700k/MW.

How do cost and performance projections work?

The cost and performance projections developed in this work use a literature-based approach in which projections are generally based on the low, median, and highest values from the literature. Table 1 lists the publications that are presented in this work.
