From 4 Databases to 1: How Plexigrid Replaced InfluxDB and Got 350x Faster Queries with Tiger Data

In an effort to enhance low-voltage grid capacity and efficiency, Plexigrid, an electrical grid optimization software company, focuses on providing Distribution System Operators (DSOs) with real-time visibility and management tools, leveraging TimescaleDB to optimize grid network utilization. Traditional grid models, which relied on one-way power flows, are being challenged by rising demand and decentralized energy sources like solar and electric vehicles. Plexigrid's solution minimizes the need for costly infrastructure overbuilds by allowing DSOs to operate closer to their existing capacity through real-time data aggregation, enabling dynamic load adjustments and predictive maintenance using digital twins. Transitioning from a four-database system, including InfluxDB, to a unified PostgreSQL/TimescaleDB architecture has markedly improved data ingestion reliability, reduced storage requirements, and enhanced query performance by up to 350 times, facilitating more efficient data management and operational scalability. This strategic shift has provided DSOs with more reliable insights, enhancing grid stability and supporting higher renewable energy integration without extensive infrastructure upgrades.
