GravityGrid identifies, evaluates, and develops optimal sites for pumped hydroelectric storage. The most proven form of grid-scale energy storage, deployed at the locations where it creates the most value.
GIS-based screening across elevation differentials, water availability, geology, and land ownership to surface high-potential closed-loop sites before anyone else sees them.
Proximity to transmission infrastructure, grid congestion zones, retiring baseload plants, and state storage mandates. Sites that score high technically must also score high economically.
FERC preliminary permits, environmental studies, water rights, interconnection agreements, and capital partnerships. From identification through investment-ready project packages.
Wind and solar are intermittent. Data centers demand 24/7 power. The gap between generation and demand is widening, and only long-duration storage fills it.
PSH has operated reliably since 1930. The challenge was never the turbines. It's finding the right sites, navigating FERC, and assembling the capital stack.
$15B in DOE funding. Expedited FERC licensing for closed-loop projects. State storage mandates in CA, NY, and expanding. The regulatory environment has never been more favorable.
A FERC license grants 40 years of operation. These aren't 5-year battery replacements. They're generational infrastructure that appreciates as grid demand grows.
Building the infrastructure layer that turns terrain into clean energy assets.
