Publication of Pressure Forecasts

17 August 2018

Following industry feedback, from 17 August 2018 National Grid will be commence a pressure forecasting service.

We have heard from you, our Customer and Stakeholders across the industry, that having more information about likely pressures on the Network would add significant value to your operations and commercial decisions. In response, we have developed a weekly forecast, available on our Transmission Operational Data page under Supplementary Reports:

https://www.nationalgrid.com/uk/gas/market-operations-and-data/transmission-operational-data

The weekly publication will consist of an indicative forecast pressure range at system entry points on the Gas Transmission Network, and will be valid for the following week. The forecasts will be  based on prevailing network configurations and assumed supply/demand patterns using the best available information that we have at that time. As we have previously highlighted within day changes to supply and demand do have an impact on pressures observed across the network, so there is likely to be some level of uncertainty in the forecasts.

We will aim to enhance this data based on feedback, so please continue to let us know your thoughts, we are particularly interested to hear how this data can aid decisions making and the value it adds to your business.
