Technology

Grengine builds modular, stackable battery energy storage systems (BESS) with integrated cybersecurity. Founded by Connie Stacey in Edmonton, Alberta. Their units are designed as direct diesel generator replacements -- same form factor, same connections, zero emissions.

Key Differentiators

Military-grade cybersecurity integrated at the firmware level (not bolted on). Canadian manufacturing = NATO-allied supply chain with zero Chinese dependency. True plug-and-play: one person can deploy a unit in under 30 minutes. Stackable/modular: scale from 15 kWh to multi-MWh without redesign. Diesel generator form factor compatibility -- swap diesel for battery in existing infrastructure.

Data Center Value Proposition

Data centers are prime targets for cyberattacks -- including through their energy infrastructure. A compromised UPS or battery system is a vector for taking down compute. Grengine is the only BESS with cybersecurity designed in from the ground up. For edge deployments, their diesel-replacement form factor means no permitting battles over fuel storage.

Cost / ROI

Diesel fuel costs $0.30-0.50/kWh generated. Grid electricity at $0.08-0.15/kWh stored in Grengine = 50-70% fuel cost savings. Zero diesel maintenance costs ($5-15K/year per generator eliminated). Demand charge reduction: $5-20/kW/month savings. No fuel spill liability or environmental compliance costs.

Technology Readiness

TRL 7-8 -- Commercial units deployed. DIANA accelerator advancing cyber-secure dual-use capabilities.

Summary

Grengine builds modular, plug-and-play battery storage with military-grade cybersecurity -- the only BESS designed from the ground up for defense and critical infrastructure. Canadian-manufactured (NATO-allied supply chain). Replaces diesel generators with zero-emission, silent, hack-proof energy storage. One person deploys in 30 minutes. Scales from kW to MW.
