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

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.
