Demand growth scenarios and risks
Response to Limitations
• Potential for deferred capital expenditure, but:
– Major projects have long lead times
– Some existing infrastructure approaching full utilisation at peak
periods
– Require ‘headroom’ to take major infrastructure out of service for
renewal
•
Location, location, location!
–
–
•
WDM initiatives not intended to prevent development
Mismatch between areas of saving and development nodes
Response
–
–
First see effectiveness of WDM initiatives by location
Complete current projects but defer future projects

Augmentation & Renewal Planning
• Augmentation
– Increase capacity to meet future demands (quantity & quality)
– 20 year view of projects based on 35+ year view of demands
– Projects connected to customers per system
•
Renewal
–
•
Extend life of existing assets (replace, refurbish, upgrade)
Integrated
–
–
Many projects combine augmentation and renewal (eg pipelines)
Integrate at plant, site and system level
