Industry Standing Data (ISD) is a centralised, common set of reference information used by all electricity market participants, a directory that ensures all energy suppliers, network operators, and third-party service providers are using the same foundational data to interpret information related to each metering system.
What is Industry Standing Data?
Industry Standing Data (ISD) is an enhanced version of our Market Domain Data and Line Loss Factor services, but with fewer manual processes to maintain it. This will save both time and resources for BSC Parties and Elexon colleagues.
Industry Standing Data (ISD) is being introduced as part of the Market-wide Half-Hourly Settlement (MHHS) Programme and will replace Market Domain Data.

ISD Release Schedule
The ISD Release Schedule shows the Change Request submission deadlines, Publish date and Go-Live date for each Version of Industry Standing Data.
During the MHHS Transition Period, an additional ISD catalogue will be published each month containing changes relating only to newly qualified MHHS participants.
ISD Circulars
We issue two types of Circulars as part of the ISD Release process:
Impact Assessment Circulars
These inform you of the proposed general changes to be included in the next Version of ISD. You are expected to carry out an impact assessment on these changes.
Please note: An Impact Assessment Circular is not issued when the release is limited to publishing an ISD catalogue to include newly qualified MHHS participants only.
Final Circulars
These confirm the approved changes being made to the next Version of ISD. Once issued, changes cannot be excluded from that Version.
How to get ISD data
Industry Standing Data is available on the Elexon Portal.

Receiving ISD files
When a new version of the ISD catalogue is published, participants will receive a notification from the Data Integration Platform (DIP) via an IF-047 message.
