Atlan energy storage battery price trend

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 an energy storage system cost?

Energy storage system costs stay above $300/kWh for a turnkey four-hour duration system. In 2022, rising raw material and component prices led to the first increase in energy storage system costs since BNEF started its ESS cost survey in 2017. Costs are expected to remain high in 2023 before dropping in 2024.

What is the biggest demand for lithium-ion battery storage?

Lithium-ion battery storage has expanded by orders of magnitude since the 1990s, with new devices creating ever-larger demand. Camcorders came first, followed by personal computers and then smartphones and other personal electronics. In the 2010s, the newest and far biggest demand center emerged:electric vehicles.

Is energy storage still booming?

Despite this price movement,the sector is still booming. BloombergNEF expects global energy storage capacity installed in 2023 to be almost double the volume installed in 2022. By the end of the decade, annual installations should be three times higher than this year. The big demand drivers for energy storage buildout will sound familiar.

Do projected cost reductions for battery storage vary over time?

The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. Figure ES-1 shows the suite of projected cost reductions (on a normalized basis) collected from the literature (shown in gray) as well as the low, mid, and high cost projections developed in this work (shown in black).

What is a good round-trip efficiency for battery storage?

The round-trip efficiency is chosen to be 85%, which is well aligned with published values. 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.
