Overview
HMV Minster Energy Storage System is a 7 MW pumped hydro storage facility in Ohio, United States, operated by Half Moon Ventures LLC. It provides grid-scale energy storage services.
HMV Minster Energy Storage System is a pumped hydro storage facility located in Ohio, United States, with a capacity of 7 MW. Owned by Half Moon Ventures LLC, the plant is operational and contributes to the region's energy storage infrastructure. Pumped hydro storage is a mature technology that uses water reservoirs to store and generate electricity, supporting grid stability and renewable energy integration. The facility operates under the regulatory framework of the United States, which includes safety standards such as NFPA 855 for energy storage systems and UL 9540/9540A for battery systems, though pumped hydro has distinct safety considerations. In Ohio, energy storage is increasingly recognized for its role in peak shaving and frequency regulation, aligning with state-level renewable portfolio standards and grid modernization efforts. Environmentally, pumped hydro storage offers low operational emissions and long operational life, but requires careful siting due to water usage and ecological impacts. The HMV Minster facility's location in Ohio supports the local grid by providing dispatchable power, reducing reliance on fossil fuels during peak demand, and enhancing the resilience of the regional energy system.
Environmental context
Pumped hydro storage facilities like HMV Minster rely on water reservoirs, which can affect local hydrology and ecosystems. Proper siting and management are essential to minimize impacts on aquatic habitats and water resources. In Ohio, the facility's operation supports grid stability and renewable energy integration, reducing greenhouse gas emissions by displacing fossil fuel generation during peak demand. The technology's long lifespan and low operational emissions make it a sustainable option for large-scale energy storage.
Frequently asked questions
HMV Minster Energy Storage System is located in Ohio, United States, at coordinates 40.3988, -84.3873.
HMV Minster uses pumped hydro storage, which stores energy by pumping water to an upper reservoir and releases it through turbines to generate electricity.
The facility is owned by Half Moon Ventures LLC.
Pumped hydro storage in the US is subject to federal and state regulations, including dam safety standards by FERC and environmental reviews under NEPA. While NFPA 855 primarily addresses battery storage, pumped hydro follows specific guidelines for hydraulic structures.
Pumped hydro storage provides grid services such as peak shaving, frequency regulation, and renewable energy integration, helping to balance supply and demand and enhance grid reliability in Ohio.
