Further to the news item published on 19 December, please be aware that the current Energy Flow Data publishing arrangements for Barrow and the Short Range Storage Sites (Avonmouth, Dynevor, Glenmavis & Partington)  will change.

In the “Instantaneous Flows into the NTS” page, National Grid currently publishes a Terminal Flow for Barrow and the Storage Sites within the Zone Supply section. 

Going forward over the course of the next 24 hours, National Grid will separately publish total ASEP flows within the Terminal section for Barrow . Boil off flows will not be included in the Zone Supply table as they are now. The Terminal Section will therefore shows Storage Sites with summated values representing export flows plus Boil Off flows.
