Liggi

Liggi is a term used in speculative design and discussions of future energy systems to describe a modular, decentralized energy distribution concept. In this envisioned framework, energy generation, storage, and consumption are coordinated through a peer-to-peer network that minimizes central control and optimizes use of local resources.

In liggi concepts, the system is composed of small, portable nodes called liggi units. Each unit contains energy storage, sensing, and communication capabilities. Nodes connect via a low-latency mesh network, sharing status and demand signals, and collectively negotiating energy exchange to balance supply and demand across the locality.

Design goals emphasize resilience, flexibility, and inclusivity. By reducing transmission distances and enabling rapid deployment, liggi-inspired systems aim to lower losses and support communities during outages. Open standards and interoperability are often highlighted to ensure devices from different manufacturers can participate in the same grid.

History and usage: The term emerged in the 2020s within academic papers, design studios, and speculative fiction as a way to explore how urban energy systems might evolve with digital coordination and renewable resources. Real-world adoption remains limited to experimental pilots and theoretical discourse.

Relation to existing concepts: Liggi is closely related to microgrids, peer-to-peer energy sharing, and distributed energy resource management. While not a widely adopted standard, it serves as a rhetorical and design device to compare centralized grids with decentralized, cooperative approaches.
