AEP Bluffton NaS Pumped Hydro Storage Facility, Ohio, USA

AEP Bluffton NaS is a pumped hydro storage facility located in Ohio, United States, owned by Ohio Power Co. With a capacity of 2 MW, it is a small-scale energy storage plant that plays a role in local grid management. The facility is operational and contributes to the region's energy infrastructure. The plant operates under U.S. regulatory frameworks such as NFPA 855 for energy storage system safety and UL 9540 for product safety. Pumped hydro storage is a mature technology that provides long-duration energy storage, typically used for load balancing and grid reliability. In Ohio, such facilities support the integration of renewable energy sources and help manage peak electricity demand. Environmentally, pumped hydro storage has a low operational carbon footprint but requires significant water resources and land use. The facility's location in Ohio benefits from the state's diverse energy mix, and its small scale minimizes local environmental impact. The plant's grid interconnection role enhances energy security and supports the transition to a more resilient power system.

Pumped hydro storage facilities like AEP Bluffton NaS rely on water elevation changes to store and release energy, which can affect local hydrology and ecosystems. The 2 MW scale suggests a relatively small footprint, reducing potential environmental disruption. In Ohio, such plants help balance intermittent renewable energy sources, contributing to grid stability without direct emissions during operation.
