The building blocks of investment planning
Investment plans are built from a consideration of the motives driving investment and not from a requirement to ensure a nominally periodic turnover of asset classes

Closing remarks
- We are supportive of the ‘ building block’ approach that
Ofgem have proposed and believe it is a step forward
- Utilise the building block approach to understand
individual DNO assumptions and resultant plan Do
- Benchmark the DNO against its own assumptions
- Ensure ‘ definitions’ are appropriately documented
- Recognise the requirement for j udgement in forecasting
Use analytical benchmark comparisons across DNOs Don’ t
- Use analytical benchmark comparisons across DNOs
- ‘ Cherry-pick’ what might appear to be best practice
- Accept outputs of ‘ crude’ forecasting models
Panel 6
- ‘ Joined-up’ thinking is paramount
