▪ New complex operational scenarios and analyses



Project Creation

▪ Distribution has a compelling need for more accurate, more accessible, more timely network models than its current approach to data management supports.

▪ EPRI is uniquely positioned to address this need

EPRI Power Delivery & Utilization

• Transmission

• Distribution

• Information, Communication & Cyber Security

Collaborative approach Depth and breadth of knowledge



▪ Started in 2012▪ Directly engaged 13 transmission utilities so far▪ Produced 8 reports, including

– “Using the CIM for Network Analysis Data Management” (Product ID 3002002587)

▪ Over 5,000 downloads

– “NMM Technical Market Requirements: The Transmission Perspective” (Product ID 3002003053)

▪ Over 1,500 downloads▪ Used by 8 utilities in NMM procurements▪ Has influenced NMM tool products

▪ Has provided valuable input into CIM standard development

▪ Goal“A practical industry architecture for both product vendors and utilities that can guide the design and implementation of enterprise grid model management”

▪ Approach1. Leveraging earlier EPRI network model management work done in

transmission domain

2. Core team of passionate experts with wide variety of perspectives

3. Real-world grounding from participating utilities

4. Architecture development using EA philosophies and tools

5. Vetting of architecture by vendors and utilities

6. Incorporation of results into data exchange standards

Designing a reference architecture for an industry is

DIFFERENT from delivering a solution for one utility

2. - a real, but surmountable, challenge

– No ‘standard practice’ for a industry data management architecture
