High-Level Software Development Activities• ISO-NE responsibilities include:
– All DNP3 communication-related software including DDE model synchronization
– EMS User Interfaces and Dispatch Interfaces to Settlements
– Customer Asset Management (CAMS) Enhancements
– Settlements System
• Outside Vendor responsibilities include:– DR Model Management including monthly model update capabilities
within the EMS
– Various Real-Time Dispatch functions including security-constrained study tools
– Various real-time prediction tools
– Training/Testing simulator enhancements
– Software interfaces to ISO Systems

Integration of DR within SCADA – Logical View

1. RTU connections are initiated from ISO; no inbound connections allowed to CFE
2. Once a connection is established to RTU, ISO efficiently polls the RTU for changes; no unsolicited data is allowed from the RTU
3. ISO pushes dispatch instructions to the RTU in the form of Analog and Binary Outputs

Frame Relay Circuit Cost and Availability
• Within continental US, 56K circuit costs about $200/month or $400/month for two circuits – Update: Request for Quotes for about ½ of the DDE’s have been received. It is expected that DDE’s will have the required Router and Frame Relay circuits no later than 11/1/2009 for testing.– Atlanta, Bethlehem (PA), Boston, Buffalo, Dallas, Middletown
(CT)• $431/month
• Installation time approximately 1 month

Frame Relay Circuit Cost and Availability
• ISO-NE telecommunication vendor is currently establishing availability and quotes for Frame Relay outside of continental US – Update: Quotes have been received and will need to be discussed with affected DDE’s outside of this meeting
• Monthly charges are higher– Single frame relay– Single Canada private line

DR Model Synchronization and Testing1. DR Resource/Assets can change on a monthly basis2. ISO-NE and DDE’s will establish an efficient means for
exchanging DR ‘meta-data’ for the purpose of regular RTU configuration and testing prior to the start of each month
3. ‘Meta-Data’ will consist of information needed to establish identity and other attributes of Resource and Assets
4. ‘Meta-Data’ will consist of information needed to establish mapping between the Resource/Assets and DNP objects within the RTU Master and Slave
5. ‘Meta-Data’ will be automatically be generated by ISO-NE DR Model Management System based upon information derived from CAMS
6. DR ‘Meta-Data’ will also include test data to automatically test the integrity of the new model within the RTU Master and Slave
