Electricity Market Information

Information on the Electricity industry is held across 4 industry websites, provided by National Grid and Elexon.  Industry parties have indicated that this can make it difficult to find the required information quickly and that a central location for key data would be beneficial. 

In response National Grid has worked with Elexon to develop the new Electricity Data Summary webpage, which provides key information from these websites.  National Grid and Elexon are continuing to further develop this summary page. 

Industry Engagement

National Grid has engaged with the industry to develop the new summary page and produced a Consultation Report, on 1 August 2007 to further seek the industry's views. 

The conclusions from this consultation can be found in the Market Information Conclusions Report published on 16 October 2007.

Further to the recommendations in the conclusions report, National Grid has raised two Market Information Modification Proposals.  These were:
P219 – Consistency between forecast and outturn demand, and
P220 – Provision of new data items for improving market information

The main purpose of these modifications was to improve information transparency, provide better market signals for all market participants, including small players,
so that market participants are better able to manage their positions, thus facilitating more efficient market operation.

These two modifications specifically focus on prioritised areas for the provision of new data items to provide consistency, clarity and detail of forecast/outturn demand data (P219), and a daily summary page with key market information in one place (P220).

For further details on these two modifications, please visit the Modification area of the Elexon website.

National Grid continually welcomes ideas and feedback on improving Electricity Market Information.  For such feedback, please contact richard.j.price@uk.ngrid.com (tel: 0118 936 3391).
