The founders of B2G Energies noticed commercial facilities adopting solar panels and batteries in isolation. These expensive assets were rarely integrated or fully monetized. They launched the startup to coordinate generation, storage, and grid participation into a single system.

😟 Problem

Commercial and industrial facilities face high electricity costs and steep peak demand charges. Deploying solar and battery storage requires significant upfront capital. These businesses also lack the technical expertise to optimize energy consumption and storage.

💡 Solution

B2G Energies develops and operates distributed energy infrastructure using flexible financing models. The startup integrates solar panels, battery systems, and energy management controls.

Key capabilities include:

• Reducing grid consumption via on-site solar generation.
• Lowering peak demand charges by discharging batteries during high-load periods.
• Shifting electricity usage to lower-cost periods.
• Creating additional value through demand response and grid services.
