Information Transparency Proposal Transmission Workstream 2 nd November 2006 Presentation by Abid Sheikh, energywatch and Angela Love, Poyry Energy

Agenda Background Considerations Current Landscape Way Forward

Background Tight supply/demand positions and threats to security of supply have led to a “clambering” for information and market transparency Various initiatives have come forward to address concerns and make information more readily available to industry participants and interested parties: –Modifications 006, 097, 104 and 121 –DTI/UKOOA initiative on North/South aggregated physical flows

Considerations There are perceived benefits from greater transparency and availability of information, with Ofgem believing this to be a requirement to ensure economic and efficient operation of the market There are questions over commercial sensitivity of information and also the benefits to the wider market of the release of certain aspects of information What is the optimum information transparency position and how do we ensure cost effectiveness?

Current Landscape Flows into the NTS – by entry zone Terminal supplies – instantaneous flows Within day daily reports –NB05 – System Nomination Balance –NB92 – System Status Information –NTSAFF – Aggregate Forecast flows into the NTS –NTSAPF – Aggregate physical flows into the NTS –NTSDE – D-2 to D-5 NTS demand forecast report –SISR03 – Forecast Demands

Current Landscape After day daily reports –NORD01 – Daily balance report –NORD06 – Gas trading report –SISR04 – Actual demands –NTS Entry end of day flow Does current information provision satisfy market needs?

Way Forward It is proposed that discussion and analysis of information transparency should commence, involving customers, Shippers, Storage Operators, Ofgem, energywatch and interested industry parties Consideration should be given to the optimum provision of information, in light of cost benefit and promotion of the relevant objectives of the UNC Usefulness and commercial sensitivity of the information should also be considered, as well as whether or not aggregate information is sufficient and mitigates against commercial risk
