I25 Battery Storage - 4 MW Pumped Hydro Storage Facility in Colorado, USA

I25 Battery Storage is a pumped hydro storage facility located in Colorado, United States, owned and operated by United Power Inc. With a capacity of 4 MW, it is a small-scale energy storage plant that plays a role in local grid management and renewable energy support. The facility operates under U.S. regulatory frameworks including NFPA 855 for energy storage system safety and UL 9540/9540A standards for battery safety testing. Pumped hydro storage is a mature technology that provides long-duration energy storage, typically used for load balancing and grid reliability. In Colorado, such facilities contribute to the state's growing renewable energy portfolio. Environmentally, I25 Battery Storage helps reduce reliance on fossil fuels by enabling greater integration of intermittent renewable sources like solar and wind. Its location in Colorado supports the state's clean energy goals, and the facility's operational status ensures ongoing grid benefits without the emissions associated with conventional peaker plants.

Pumped hydro storage facilities like I25 Battery Storage provide grid-scale energy storage with minimal direct emissions during operation. However, they require significant water resources and can impact local aquatic ecosystems. In Colorado, water availability is a key environmental consideration, and facilities must comply with state water rights and environmental regulations. The facility's small scale (4 MW) reduces its environmental footprint compared to larger projects.
