Analysis: Significant Energy Storage Capacity Additions Keep Costs Low and Power Reliable in Texas

A new ACP analysis shows that the recent addition of 5 gigawatts (GW) of energy storage in Texas not only enhanced grid reliability, but also helped keep electricity costs down for consumers—even during record demand and extreme weather events in 2024. By releasing stored energy when the grid needed it most, battery systems helped avert conservation appeals and provided an estimated $750 million in cost savings for Texans.

Key Takeaways:

• Reliable Power: Rapid deployment of energy storage enabled Texas to meet soaring electricity demand and avoid conservation calls, even amid historic peak usage.
• Lower Costs: Energy storage contributed $750 million in cost reductions for consumers.
• Future-Ready Grid: With more than 4.5 GW under construction and an additional 7.3 GW in the pipeline, Texas stands ready to maintain a more affordable, flexible, and resilient energy grid moving forward.
