Integrated Demand Management ?• A software decision support tool
– Creates optimised pipeline pumping schedules– Provides pipeline models for operational “what‐if” analysis– Used by systems engineers and pipeline operators– Built using the OSIsoft tools and databases that are SA Water’s
Operational Data Store (ODS)– Developed by SA Water and Ericsson‐Optimatics

Water Supply in South Australia• Typical annual water consumption = 220GL
– Metropolitan Adelaide ~ 140 GL– Country ~ 80 GL
• Typical Metropolitan Adelaide water sources– River Murray 80%– Surface water 20%
• Typical annual pipeline pumping power cost ~ $20,000,000

Business Drivers• High and rising electricity costs
– Variable tariffs
• Concerns about raw water supply continuity– Limited storage with highly variable natural inflows– High dependence on the River Murray
• Complex pipeline‐reservoir‐river network• Frequent operational constraints on pipeline operations

Monitoring and Control Infrastructure • One SCADA system covering South Australia
– ~150,000 tags
• Large pipelines controlled via SCADA from a control room• SCADA network is separate from the business network• Pi historian in place on business network• Limited business visibility of operational data• Few data quality management policies or procedures

IDM System Development Objectives• Energy cost savings of 2% to 5% per annum by pipeline• Optimisation to both minimum energy cost & consumption• More accurate pipeline network simulation
– Planning reservoir levels and pipeline transfer volumes
• Appropriate features and complexity to suit users– Data management, fault resolution
• Robust and adaptable pipeline control

IDM Development • First pipeline operational optimiser deployed in 1999
– Optimised pumping schedules and forecasted power consumption– Ran on DEC Alpha computers
• Redevelopment project commenced in early 2008• Contracted with Ericsson‐Optimatics in April 2010• IDM System “entered production” in June 2012

Benefits Realised• Energy cost savings of 3% – 8%• Improved network simulation and forecasting• Forced repairs to critical SCADA data feeds• Forced pipeline infrastructure asset data updates• Forced clarification of pipeline operating procedures• Created business interest in software decision support tools

Project Challenges• Very technical topic involving many disciplines
– Hydraulic modelling and network optimisation – SCADA system integration and live data access– IT system development, testing, user training, support, etc.
• Required accurate knowledge of the infrastructure• Difficult to quantify benefits beyond energy savings • Implementation involved changed work practices and new
skills

Lessons Learned• Development environment was cobbled together• Business users were heavily involved from the start• SCADA data and field instrument fix‐ups were slow• ProcessBook has significant limitations as a UI
– ‘90s look, limited programmability
• Tender process included a limited prototype
