BNEF finds 40% year-on-year drop in BESS costs
BNEF analyst Isshu Kikuma discusses trends and market dynamics impacting the cost of energy storage in 2024 with ESN Premium.
The price is the expected installed capital cost of an energy storage system. Because the capital cost of these systems will vary depending on the power (kW) and energy (kWh) rating of the system, a range of system prices is provided. 2. Evolving System Prices
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.
3. Purpose The annual Energy Storage Pricing Survey (ESPS) is designed to provide a reference system price to market participants, government officials, and financial industry participants for a variety of energy storage technologies at different power and energy ratings.
This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.
Battery Energy Storage System (BESS): The complete DC level energy storage system and comprises one or more storage modules with the accompanying BOS so the unit can be electrically connected with other electrical components.
