10. ICCP at NSP Today ICCP is NSP’s communication interface standard for
external utilities,external marketing entities, power pool types of interfaces
internal emerging business applications.
ICCP for connectivity to other utilities and power plants, as well as to internal systems
NSP has implemented more than 20 discrete instances of ICCP

11. ICCP Benefits Increased flexibility and capability
Retrieve more information from substations and distribution automation
Feed data into control center via open, standard protocols
Minimize investment in legacy protocols
Less proprietary, more modular, more easily enhanced over time

12. ICCP Benefits Dramatic time savings
adding a new system takes 40 person-hours versus the 3-12 person-months typical of old custom solution approach
With a standardized integration environment, everyone knows ‘the rules’
System upgrades don’t take the system down
