Energy Optimisation Feasibility – Westernport Water

Westernport Water (WPW) is currently exploring costs and feasibility to become Net Zero in its operations. To achieve this, WPW has partnered with 12 other Victorian water corporations to purchase clean energy from the Kiamal Solar Farm in north west Victoria. In addition, WPW installed a commercial-scale solar system to provide power to multiple sites, and recently commissioned a solar array at the Cowes Waste Water Treatment Plant.

Following a complex analysis, and following AS3598 Type 2 methodology, Bridgeford Group developed a comprehensive feasibility report that identified a range of opportunities to further reduce emissions and improve energy productivity at the Cowes Wastewater Treatment Plant on Philip Island, and the Ian Bartlett Water Purification Plant at the Candowie Reservoir. The feasibility report highlighted and prioritized a range of site-specific investment opportunities, including:

• Water pump and aeration optimisation
• 240kWh in battery storage opportunities to ensure more solar energy is self-consumed
• Virtual Energy Network (site to site energy sharing)
• Biogas co-generation
• Supporting infrastructure (electrical and mechanical)upgrades
• Fleet vehicles transition to EVs

Bridgeford Group’s expertise in energy optimisation and net-zero not only provided a detailed report outlining the
projects, the report also included detailed investment details including initial outlay, payback periods, return rates and emission reductions. Since the audit, Bridgeford Group has helped WPW implement a virtual energy network, allowing WPW to share excess solar between sites, drastically improving solar system pay back and emissions reductions.
