We are a mission-driven company designing, building, and deploying products that electrify the built environment, reduce carbon emissions, and slow the effects of climate change.

At SPAN, we believe in:

  • Enabling homes and vehicles powered by clean energy

  • Making electrification upgrades possible

  • Building more resilient homes with reliable backup

  • Designing a flexible and distributed electrical grid
