Agenda
• Quick introduction to the Danish DSO landscape
• Experiences from the first integrations
• Sharping the saw
• Future projects
Danish DSO landscape
Facts:
• In year 1995 there were 214 DSOs
• In year 2015 there were 61 DSOs
• 50-60 kV (HV), 10-15 kV (MV) and 0,4 kV (LV)
• 99% cables
• Balanced network – also LV
Main challenges:
• Regulation – i.e. benchmarking and retail market
• A lot of DERs on the MV network (some DSOs)
• Compete to be the most effective and innovative
Experiences from the first integrations
• Many unforeseen data quality issues found in the staging phase
• Difficulties in maintaining the as-build network consistency over time
• Each business unit use different vocabularies and domain models
• The existing domain modelling and integration practices could not keep up
with the increasing pressure to support innovation at a much faster pace
Sharping the saw
DeWalt's first radial arm saw that cut costs beyond his own expectations
Sharping the saw Sharp focus on Business Processes

Use Domain Driven Design (DDD) to tackle complexity

Future projects
• CIM based Project Tool
• Proactive Data Governance Tools
• LV Calculation Processor using InterPSS
• Experiment with Event Sourcing etc.
