o Enexis manages the energy netw orks in the Northern, Eastern and Southern parts of the
Netherlands.
o We provide electricity to 2,6 million and gas to 2 million customers.
o We maintain and renew the network (power cables, gas pipelines and substations) and care for
high standards of network reliability and safety

Conclusion
• Dataownership strategy and quality is a must
• One logical network model and single source of data truth
• Data becomes more and more realtime and will only increase in the future
next steps • Data validation based on quality and completeness
• Make real time load data available
• Establish the Dynamic Data Ware House Accessibilty of the data to gain the benefits of “BIG” data analysis to evolve with dedicated tools
