How It Works

The Mine Is the Battery.

Water stored in the upper reservoir falls through the shaft, drives a turbine at depth, and is pumped back overnight using curtailed renewable energy. Energy stored as potential head. Power delivered firm, on demand, behind the meter.

The Problem We Solve

AI compute demand is outpacing the grid. Interconnection queues run five to seven years. ESG mandates restrict gas. LurraGrid converts existing underground infrastructure into firm, behind-the-meter power for hyperscale operators — delivered faster than the grid can build.

The Architecture

Three Layers. One Platform.

01

LurraCore

Underground Storage & Dispatch

The mine is the battery. Existing hard rock shafts and cavities become upper and lower reservoirs, storing energy as potential head. No new excavation. No new permitting. The infrastructure already exists.

02

LurraCascade

Patent-Pending Continuity System

Dual-reservoir threshold switching maintains uninterrupted power delivery. Automated actuators engage at 20% reservoir threshold, seamlessly transitioning between cascade stages. Patent pending, prior art published CERN Zenodo May 2026.

03

LurraCharge

Curtailed Energy Recharge Layer

Recharges overnight on curtailed wind and off-peak grid power — energy the market cannot absorb. The arbitrage spread between curtailed input and firm daytime output is the business model.

Peer-Reviewed Foundation

Three years of peer-reviewed academic research. One patent-pending continuity system. One platform.

Built on foundational research conducted at Michigan Technological University under the MTU PUSH program, funded by the Alfred P. Sloan Foundation. The LurraCascade Continuity System was published as prior art on CERN Zenodo, May 5, 2026.
