Post Day Data Discussions

Tony Watts
Project Manager at National Grid

We have begun meeting 1-1 with our stakeholders to discuss the post day data published on MIPI. (As a reminder, post day data is system data pertaining to a gas day which is published after the Gas Day has occurred.) The key take-away's from the discussions we have undertaken to date are:

- All stakeholders download the supply and demand post day actual flow data. A few stakeholders also download capacity data. Stakeholders typically download the data using Application Program Interfaces (API’s), however the Data Item Explorer is also used for bespoke data requests. National Grid Reports are only used to provide an understanding of how data items relate to one another.

- Stakeholders combine Grids data with their own to build internal visualizations. Stakeholders generally value the Prevailing View screen, suggesting improvements, avoiding the confusing mix of real time and post day data for different gas days and focusing better visualization of the system status for the current gas day.

- Stakeholders value good quality data, and would be interested in improvements to data consistency, particularly consistent supply and demand data.

To enhance this feedback, we will continue to hold 1-1’s with stakeholders who express an interest in participating in such meetings. We will also publish specific questions relating to post day data on the gas operational community website. Please let us know if you would like to get involved with these discussions.
