FlexSplice Hub - The Engine Behind FlexViz

What is FlexSplice Hub?

FlexSplice Hub is the server platform that manages communication between utilities, flexibility providers, and distributed energy resources (DERs).

It acts as a Virtual Top Node (VTN) for OpenADR and a Utility server for IEEE 2030.5, ensuring demand response signals are delivered reliably and securely. (IEEE 2030.5 connection coming Q1 2026).

FlexSplice Hub goes beyond standards compliance with event scheduling, reporting tools and full API access for deeper integration.
