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.
The most dominant technology being deployed in recent years across the electric grid are battery energy storage systems (BESSs), which interconnect to both distribution and transmission systems.
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).
How can a battery module & pack Testing Service help?
Our battery module and pack testing services can evaluate compliance with the applicable battery testing safety standards and regulations. Our building inspections help identify building compliance gaps and guide improvements for proper operation of your life safety, fire safety and security systems.
We are able to test primary and secondary (rechargeable) batteries with chemistries including alkaline, lithium-ion (Li-ion), nickel metal hydride (NiMH), lead acid, and nickel-cadmium (NiCd) as well as newer technologies such as zinc-based and flow batteries.
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.
