Immedia Power is an energy infrastructure company addressing one of the biggest bottlenecks in electrification: slow and constrained grid expansion.

Electrification is accelerating, but new high-voltage grid connections can take 5–10 years, preventing EV fleets, edge data centers, ports, and industrial sites from scaling operations and generating revenue. As a result, these sites are forced to rely on inefficient and carbon-intensive alternatives, delaying progress toward net-zero goals.

Immedia Power provides permanent, utility-grade on-site capacity delivered in weeks instead of years, with a small physical footprint. Our flagship product, GX230, is a modular 230 kW multi-fuel power system that synchronizes directly with existing electrical infrastructure and operates as additional native grid capacity rather than backup power. The system supports LPG, CNG, biofuels, synthetic fuels, and hydrogen blends, enabling a clear pathway away from diesel while remaining deployable today.

Multiple units are orchestrated by proprietary software that intelligently manages load, peak demand, preventative maintenance, and output across single or multi-site deployments. The system combines high power density, ~42% utility-scale efficiency, universal grid integration, and structurally lower CAPEX per kW than incumbent solutions.

Immedia Power has completed a proof of concept, signed pilot LOIs, and is working with an experienced European development partner. Our solution enables faster electrification, reduces reliance on diesel generators, improves energy efficiency, and unlocks immediate revenue growth for energy-constrained sites

Nugen turns power from a bottleneck into a strategic advantage: clean, modular, on-site energy wherever growth demands it. We deliver swappable solid-state energy cartridges that can be shipped as cargo, stored on-site, and converted into clean electricity whenever needed.

The result is a compact system that delivers up to 30% more usable electricity per unit volume than diesel.

No pipelines. No complex storage or fuel infrastructure.

For data centers, that means clean, long-duration power that can be deployed quickly, expanded modularly as demand grows, and used for backup, grid support, or expansion without waiting years for new grid infrastructure
