What We Are
LURRAGRID is an infrastructure firm. We convert abandoned hard rock mines into LURRACORE underground pumped hydro power plants and deliver firm behind-the-meter power to AI data centers — 150 MW per node, 24 hours a day, 365 days a year — under 20-year take-or-pay Power Delivery Agreements.
The AI era demands power at a scale and speed the grid cannot provide. Interconnection queues run five to seven years. Permitting for new generation stretches longer. ESG mandates restrict gas. The result is a structural supply gap between where the compute wants to go and where the power can reach it.
LURRAGRID closes that gap. We are not building new infrastructure — we are commissioning infrastructure that already exists, at depth, in proven hard rock formations, across the United States. The mines are built. The shafts are sunk. The geology is validated. We convert them into power plants.
The Model
LURRAGRID buys an input commodity and sells an output contract. We acquire curtailed renewable energy at near-zero or negative cost — energy that wind and nuclear operators generate but the grid cannot absorb. It drives the pump train, storing energy as potential hydraulic head in underground reservoirs. The turbine runs the whole time, delivering firm power to the data center 24 hours a day, 365 days a year.
The data center operator receives power directly behind the meter — no transmission costs, no fuel exposure. The facility interconnects as load rather than entering the generation queue, and a facility with storage can accept a non-firm interconnection that a bare data center cannot.
The LURRAPDA — Power Delivery Agreement — is a 20-year take-or-pay contract. Infrastructure-grade duration. Infrastructure-grade contract structure.
Why Underground
Surface pumped hydro requires two lakes, a mountain, and a decade of permitting. Underground pumped hydro requires a mine. The United States has thousands of abandoned hard rock mines with existing shafts, proven geology, and clear ownership — mostly municipal or federal. The civil engineering is already done.
LURRAATLAS has pre-screened 950 sites across 15 states. Our first three — Mather B in Michigan, Quincy in Michigan, and Comstock in Nevada — represent three different ore types, three different depth profiles, and three different demand corridors. That is the portfolio.
The Name
LURRA
Lurra — earth goddess of the Basque people — lives underground in the caves. She holds amazing treasures in her bosom.
The mines were dug for what was below. We return to them for what they can hold. The treasure now is energy — stored at depth, dispatched on demand, delivered to the machines that run the age we are building.
