Caterva operates a distributed energy storage system called "We Network the Sun" to support Germany's energy transition (Energiewende) by providing grid stability services. The system connects many small home energy storage containers into a "swarm" that can balance electricity supply and demand like larger power plants. This solves challenges from rising solar energy in a profitable way for homeowners, utilities, and grid operators. Caterva's multi-sided business model optimizes the interests of stakeholders to pilot and scale the system with support from shareholders, industry partners, and public funding.
