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 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.

Do longer duration batteries have a lower capital cost?

On a $/kWh basis, longer duration batteries have a lower capital cost, and on a $/kW basis, shorter duration batteries have a lower capital cost. Figure 6 (left) also demonstrates why it is critical to cite the duration whenever providing a capital cost in $/kWh or $/kW. Figure 6.

Do utility-scale lithium-ion battery systems have cost and performance projections?

In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration systems. The projections are developed from an analysis of recent publications that consider utility-scale storage costs.

Does battery storage cost reduce over time?

The projections are developed from an analysis of recent publications that consider utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.
