Instantaneous Flow SOAP Service

This API offers access to the latest published real time flow data for system entry points. The information is captured in two minute intervals, then published in a set every 12 minutes.

The data returned in the GetInstantaneousFlowData operation is structured in tables containing the following detail.

Table Name	Title	Description
table1	Zone Supply	Supply data for entry zone
table2	Terminal Supply	Supply data for terminal
table3	Total Supply	Total Supply data
table4	Category Demand Flow	Demand flow by category
table5	Interconnector Flow	Interconnector export demand flow
table6	Total Demand	Total demand flow
table7	NTS Actual Linepack	NTS actual linepack flow

Information in data tables is supplied grouped by an object name, with values supplied for each two minute timestamped interval.

National Gas Transmission proactively monitors the use of this API. If you are deemed to be accessing the website at a level that we believe to be unnecessary given the current rate at which the data on the website is refreshed, we will ask you to reconsider your API script. This is to ensure that operational and commercial gas data items continue to be available to all gas community members and other interested parties in a consistent, timely and accurate manner.
