The Besst community model
When you buy a Besst battery, you’re not just investing in backup power – you’re joining a movement.
Your battery becomes part of our Virtual Power Plant (VPP) – a smart network that helps balance energy supply and demand, reduces strain on the grid, and trades energy efficiently. Together, we create a clean, stable and profitable energy ecosystem.
Here’s how it works:
• You install a Besst battery.
• You’re enrolled into our VPP, automatically.
• You can earn virtual shares based on your participation.
• We operate the VPP and generate profits.
• You receive your share – directly.
This is more than clean energy. It’s a shared economy of power – where homeowners, not just utilities, benefit from the energy transition.
Welcome to the energy community of the future.
