Google and Salt River Project (SRP), the second largest public power utility in the United States by electricity generation, have announced a groundbreaking collaboration focused on long-duration energy storage (LDES) technologies in Arizona. This partnership aims to accelerate the development and deployment of next-generation energy storage solutions, with Google funding multiple LDES pilot projects on SRP’s grid. The initiative is expected to help Google’s Arizona operations achieve at least 80% carbon-free electricity on an hourly basis by 2026. SRP is simultaneously exploring pumped storage hydropower near Apache Lake as part of its broader energy storage expansion plans. This collaboration is significant for shaping the future of energy storage, potentially impacting renewable energy integration and grid stability. The project’s outcomes could have implications for scaling and replicating similar initiatives in other regions, supporting both organizations’ sustainability goals, including SRP’s target of net-zero carbon emissions by 2050.

Our Commentary
Background and Context
The partnership between Google and Salt River Project represents a significant step in the advancement of long-duration energy storage technologies. This collaboration comes at a time when the energy sector is rapidly evolving to accommodate more renewable sources and address the challenges of grid stability. LDES technologies are crucial for enabling the integration of intermittent renewable energy sources like solar and wind into the power grid, allowing for energy to be stored and dispatched over extended periods.
Expert Analysis
This research collaboration is particularly noteworthy given the recent advancements in LDES technologies and the changing regulatory landscape in Arizona. The repeal process of Arizona’s Renewable Energy Standard and Tariff (REST) rules could potentially impact the regulatory environment for such projects. However, the continued investment in energy storage by utilities like Arizona Public Service (APS) suggests ongoing industry commitment to these technologies regardless of mandated targets.
Key points:
- The partnership leverages SRP’s position as the second-largest public power utility in the U.S. to test and evaluate LDES technologies in real-world conditions.
- Google’s funding of multiple pilot projects demonstrates a significant private sector investment in advancing grid-scale energy storage solutions.
- The initiative aligns with broader industry trends towards longer-duration storage capabilities and declining battery costs.
Additional Data and Fact Reinforcement
Recent developments in the energy storage sector provide context for this collaboration:
- U.S. battery pack prices dropped 20% in 2024 to about $115/kWh, with projections to fall below $100/kWh in 2025.
- The U.S. Department of Energy has highlighted innovation portfolios that could reduce the levelized cost of storage for various LDES technologies to approach $0.05/kWh by 2030.
- State-level procurement targets for LDES have been established in California, Massachusetts, and New York, signaling growing policy support.

In a parallel development, Google has also announced a partnership with Energy Dome, an Italian startup, to deploy CO₂ Battery technology for long-duration energy storage globally. This multi-faceted approach to LDES research and implementation underscores Google’s commitment to achieving its sustainability goals across various geographical regions.
Summary
The Google-SRP partnership in Arizona represents a significant step towards advancing long-duration energy storage technologies. While regulatory changes in Arizona may present challenges, the collaboration’s focus on real-world pilot projects and the broader industry trends suggest a promising future for LDES in supporting grid stability and renewable energy integration. The outcomes of this research could have far-reaching implications for the future of energy storage and grid management strategies worldwide.
