Expand description
mako-redispatch — Redispatch 2.0 process engine for German grid
congestion management (§§ 13, 13a, 14 EnWG).
This crate is a name reservation. Implementation is pending until
redispatch-xml (the format/XSD layer) is complete.
§Three-crate architecture for Redispatch 2.0
| Crate | Responsibility | Status |
|---|---|---|
edi-energy | IFTSTA status messages (EDIFACT) | ✅ In workspace |
redispatch-xml | XML/XSD format parsing and validation (ActivationDocument, PlannedResourceScheduleDocument, Stammdaten, …) | ✅ Implemented |
mako-redispatch | Process engine — Workflow impls, PID routing, deadline handling | ⏳ This crate |
§Domain background
Redispatch 2.0 entered into force on 1 October 2021 via the Netzausbaubeschleunigungsgesetz (NABEG) and requires all German grid operators to coordinate congestion management across transmission and distribution networks.
Redispatch 2.0 uses CIM/IEC 62325-based XML documents for the primary
data exchange (handled by redispatch-xml), and IFTSTA (EDIFACT) for
status messages (handled by edi-energy). Unlike GPKE/WiM/GeLi Gas, this
process family does not use UTILMD or APERAK.
§Planned PID range
PIDs for Redispatch 2.0 workflows will be registered in the PidRouter
once the process engine is implemented.
