XML framework (IEC TC 57/WG 16) Define a B 2 B Framework to meet requirements Follow an open process Focus on open industry standards Equal treatment toward all market participants
NATIONAL GRID Some Key Requirements • • Must support a range of low-tech to hightech, and small to large Market Participants 24 x 7 availability (99. 999%) Integrity of the market is critical to its success Market Participants are expecting bid and offer interactions to operate in “near real time” request/response mode B 2 B infrastructure must perform securely and reliably All transactions must be legally binding B 2 B infrastructure must help enforce nondiscriminatory behaviour
