Background:
Melbourne Water (MW) is a statutory authority owned by the Victorian Government, managing and protecting the city’s major water resources for the community. Melbourne Water is responsible for reliable sewerage, healthy waterways, and drainage and flood management.
Melbourne Water’s activities include the following;
- manage water supply catchments, supplying affordable and high-quality water
- treat and supply drinking and recycled water
- remove and treat most of Melbourne’s sewage, ensuring that sewerage is reliable
- manage waterways and major drainage systems in the Port Phillip and Westernport region
- provide integrated drainage and flood management services
- help to create outstanding natural community spaces.
Objective
Melbourne Water would like to investigate the electricity demand management opportunities possible for the Western Treatment Plant (WTP) and western sewerage transfer network.
Scope
The study will include assessment of:
- Historic and forecast energy load/demand profiles;
- Historic demand management opportunities implemented, and, the savings, costs and learnings from these projects;
- Missed demand management opportunities (retrospectively), detailing the opportunity costs;
- The various demand management programs currently available (FCAS, RERT, contract load shedding, etc.) and the applicability of these programs for WTP and western sewerage transfer network in the future;
- Existing monitoring systems for separate load groups across the WTP and sewerage transfer system;
- Interoperability of transfer and treatment systems with respect to delivering identified demand management opportunities; and
- Future anticipated savings, costs and risks from the various demand management opportunities of the future (stand-alone opportunities and/or projects working in tandem).
Deliverables
- Report outlining demand management opportunities implemented to date, the various demand management programs currently available and assessment of opportunity feasibility;
- Spreadsheet model outlining historic and forecast energy profiles;
- Spreadsheet model outlining missed opportunities and future anticipated savings; and
- A summary of input variables, assumptions and outputs (based on assumptions) and sensitivities to significant variables shall be produced.
