Corporate Overview

Our mission is to make renewable energy a global superpower using computing as a catalyst.

We develop and operate digital infrastructure that taps into a growing global opportunity: the convergence of renewable energy and High-Performance Computing (“HPC”). We call this model Renewable Computing™.

Across the world, vast amounts of clean energy go to waste due to curtailment. At the same time, there is a critical shortage of power for energy-intensive infrastructure like Artificial Intelligence (“AI”), HPC, and Bitcoin mining. Renewable Computing™ bridges this gap-unlocking stranded renewable energy and turning it into scalable computing power.

We build, own or co-own, and operate data centers co-located with wind, solar, and hydroelectric plants. Our modular and scalable design supports high-throughput, batchable applications such as Bitcoin, and soon, HPC/AI workloads. These facilities are managed by MaestroOS™, our proprietary operating system (“MaestroOS”), which continuously analyzes signals like local power pricing, weather, grid demand, and market conditions to optimize performance and economics.

This intelligent orchestration enables long-term asset monetization and attractive returns on invested capital. Our approach is purpose-built for the energy transition.
