Energy Storage: Lowers Electricity Costs & Reduces Ratepayer
Across the country, states are choosing energy storage as the best and most cost-effective way to improve grid resilience and reliability. Read ACP''s Fact Sheet to learn more in detail.
A comprehensive understanding of energy storage costs is essential for effectively navigating the rapidly evolving energy landscape. This landscape is shaped by technologies such as lithium-ion batteries and large-scale energy storage solutions, along with projections for battery pricing and pack prices.
Cost metrics are approached from the viewpoint of the final downstream entity in the energy storage project, ultimately representing the final project cost. This framework helps eliminate current inconsistencies associated with specific cost categories (e.g., energy storage racks vs. energy storage modules).
Trends in energy storage costs have evolved significantly over the past decade. These changes are influenced by advancements in battery technology and shifts within the energy market driven by changing energy priorities.
Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours. Li-ion LFP offers the lowest installed cost ($/kWh) for battery systems across many of the power capacity and energy duration combinations.
