Voxel Energy

Voxel Energy is a Y Combinator-backed company that energy independent data centers with solar and repurposed batteries. The company participated in the Winter 2026 batch of Y Combinator.

The best grid connection is no grid connection. Voxel builds vertically integrated energy generation and storage systems for data centers that bypass utility connection delays.

By leveraging the vast supply of second-life EV batteries and our novel DC microgrid architecture, Voxel generates datacenter power on site and drastically reduces system cost and time-to-power.

Voxel Energy was part of Y Combinator's Winter 2026 cohort, has a team of approximately 3 employees, and is actively operating.
