The Technology
LURRAGRID buys an input commodity and sells an output contract: curtailed renewable energy in, firm behind-the-meter power out under a long-term delivery agreement. Six integrated layers. One platform.
Why Data Centers Choose Us
The grid cannot serve you on your timeline. LURRAGRID can. We built the entire model around the data center development cycle.
Interconnection queues run five to seven years. ESG mandates restrict gas. By the time the grid catches up to your load, your facility has been dark for years. You need power on your schedule — not the utility's.
A LURRACORE mine retrofit takes 18 to 24 months from contract to commissioning — the construction timeline of a hyperscale data center. You sign the LURRAPDA when you break ground. Power is commissioned when your racks go live.
LURRACORE delivers 150 MW of firm baseload power per node, 24 hours a day, 365 days a year — and scales through additional nodes. Not intermittent. Not curtailed. Firm, behind-the-meter power your operators can count on every hour of the year.
LURRACHARGE feeds the pump train continuously through negotiated power purchase agreements targeting curtailed and off-peak generation, while the turbine keeps delivering. The input cost structure is what makes the economics work — and what keeps your power price locked for 20 years.
Load interconnection rather than a generation queue — and a facility with storage can accept a non-firm interconnection that a bare data center cannot
No transmission charges — you pay for generation, not delivery
No fuel price exposure — locked rate for the full contract term
No fuel, no combustion, no emissions at the node
20-year price certainty under a take-or-pay LURRAPDA
Complementary to gas — serves markets where gas cannot due to ESG mandates or permitting constraints
"We are not competing with the grid. We are serving the market the grid cannot reach — on the timeline the grid cannot meet."
Underground Storage & Dispatch
The mine is the battery. Existing hard rock shafts and cavity networks become upper and lower reservoirs. Water flows from upper to lower through a turbine to generate power, and the turbine runs at all times. On separate independent shafts, a pump train lifts water back while generation continues. No new excavation required. The civil engineering is already done — we commission it.
Capacity: 150 MW per node, scaling through additional nodes. Round-trip efficiency: 80%. Asset life: 50 years. Firm power delivered directly behind the meter to the data center load, 24 hours a day, 365 days a year.
Patent-Pending Continuity System
Conventional pumped hydro stops when the upper reservoir empties. LURRACASCADE eliminates that constraint. A dual-reservoir threshold switching system automatically engages a secondary cascade stage at 20% reservoir level, maintaining uninterrupted power delivery.

Wind and nuclear cannot throttle overnight. Grid operators log millions of megawatt-hours of curtailed generation annually — energy the market cannot absorb. LURRACHARGE acquires this energy at near-zero or negative cost through negotiated power purchase agreements. That energy drives the pump train, which runs concurrently with generation — sustaining 150 MW of continuous delivery takes roughly 187.5 MW of pumping input at 80% round-trip efficiency.
MISO territory alone logs over 1.5 million MWh of curtailed wind annually. Negative LMP pricing events are documented and recurring.
Sub-100ms Frequency Response
An EV battery bridge layer provides sub-100ms frequency response for grid interconnection requirements. LURRABRIDGE handles the instantaneous demand while LURRACORE ramps to full output — meeting both the speed of grid ancillary services and the endurance of 24/7, 365 continuous delivery.
Critical for BTM data center applications where uninterrupted power is a contractual requirement.
20-Year Take-or-Pay Power Delivery Agreement
LURRAGRID delivers power under long-term Power Delivery Agreements — 20-year take-or-pay contracts negotiated directly with data center operators. The data center commits to taking minimum volumes. LURRAGRID commits to firm delivery. Price certainty. Supply certainty. Infrastructure-grade contract structure.
Structured as behind-the-meter delivery. 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.
950 Pre-Screened Sites Across 15 States
Abandoned hard rock mines are not scarce. The United States holds thousands of them across the western and upper midwest mining belts. LURRAATLAS is our proprietary site screening database: 950 sites evaluated across 15 states against head, depth, geometry, hydrogeology, transmission access, and proximity to data center demand corridors.
Screening criteria include: minimum net head 300m, minimum depth 1,000 ft, suitable cavity geometry, proximity to transmission, and viable groundwater management pathway.
The Physics
LURRACORE is a storage and dispatch machine — not perpetual motion. Every megawatt delivered to the data center requires approximately 1.25 MW of LURRACHARGE input at 80% round-trip efficiency. The business works because the input-to-output cost spread is four to five times.
