What is the EDIFACT INFCON message?

INFCON is the UN/EDIFACT infrastructure condition message. The directory defines it as a message sent by a responsible party to other interested parties about the condition of a component in a commercial services or utilities infrastructure.

Conditions include planned outages, faults, restrictions and restorations. Parties that depend on the infrastructure, such as energy suppliers relying on a grid operator's network, use the information to inform customers and plan their own operations. Messages can describe planned work as well as unplanned faults, with start and expected end times for each.

How to read this diagram: the top row shows who sends INFCON, to whom, and which messages usually come before and after it. The lower part shows what the directory D.21A itself requires: the envelopes around INFCON and the segments and segment groups it marks mandatory. Conditional groups are listed by their trigger segment rather than drawn in full. This is the directory's minimum, not a trading partner's requirement: a message implementation guide, such as an industry subset or a partner’s own guide, usually makes some conditional groups mandatory, restricts the codes and may use an older directory.

When it is used

  • Announcing planned maintenance outages
  • Reporting faults on infrastructure components
  • Reporting restoration of service

Where it fits in the message flow

This message INFCON Infrastructure condition

No other message routinely comes directly before or after INFCON; it is exchanged when the business event occurs. If the partners agree, the receiver confirms each interchange with a CONTRL syntax and service report.

Structure

Mandatory segments in INFCON (directory D.21A)

In UN/EDIFACT directory D.21A, the INFCON message has 20 segment positions arranged in 7 segment groups. These are the segments and segment groups marked mandatory at message level, in order; a mandatory group is shown with the segment that starts it. Segments inside conditional groups are needed only when the group is used. This is the directory’s requirement, not your trading partner’s: each partner’s message implementation guide names the directory it uses, often an older one such as D.96A or D.01B where the structure can differ, makes some conditional segments mandatory and restricts the codes.

  • BGM

Practical example

INFCON in practice

A grid operator plans maintenance on a substation that will interrupt supply to several streets. It sends the energy suppliers serving those customers an INFCON with the affected component, the area and the outage window. The suppliers notify their customers, and a second INFCON reports when supply is restored.

Implementation

Implementation considerations for INFCON

  • Identify components and affected areas with agreed codes.
  • Announce planned outages within regulatory notice periods.
  • Report restorations of service as well as outages.
  • Follow national market rules where they define the exchange.
