PSE publishes business validation rules for B2B data exchange channel covering structural, planning, and redispatch data streams

PSE published on 08.10.2026 business validation rules for its B2B data exchange channel, covering all three data streams: structural data exchange, planning data exchange, and non-market redispatch process data exchange. The rules were published as technical documentation on PSE's GitHub repository across three separate repositories.

These validation rules establish the technical compliance framework that market participants and grid users must follow when exchanging data with PSE via the B2B channel, directly affecting data interoperability for structural network data, planning processes, and non-market redispatch operations. This standardization impacts operational workflows for entities interfacing with the Polish TSO's data systems.

This is a technical implementation artifact rather than a policy or market mechanism change, but it is operationally significant because it codifies the data validation logic that underpins PSE's digital interfaces for three distinct functional domains. The inclusion of non-market redispatch data validation rules suggests PSE is formalizing data governance for redispatch processes, which could have downstream implications for transparency and auditability of redispatch actions, though this announcement does not itself alter redispatch compensation policy. The publication via GitHub repositories indicates a move toward open, versioned technical documentation practices for grid data exchange standards, which may set a precedent for other TSOs or for future PSE API governance.
