Client: Western Earth Moving Civil (WEM)
Location: Elara, Marsden Park, NSW
Scope: Subdivision earthworks and site facilities for Stockland’s Elara master-planned community (over 4,000 homes, schools, parks, and retail precinct).
Technology: Makinex Renewables HPS20 Hybrid Power System
Elara, Marsden Park is one of Sydney’s largest new residential communities, designed with sustainability and livability at its core. As WEM progressed subdivision works, the need for reliable 24/7 site power posed a challenge traditionally solved with diesel generators—a costly and carbon-intensive approach.
Continuous site operations, including security surveillance and facilities, required a power solution that could run 24/7. Using conventional diesel generators would have resulted in:
High fuel consumption and rising operational costs
Significant CO₂ emissions, counter to community sustainability goals
Noise and inefficiencies from long-term diesel reliance
A cleaner, smarter alternative was needed.
Makinex Renewables deployed a HPS20 Hybrid Power System to operate continuously across a 30-day period.
Key features of the HPS20 include:
Integrated solar + battery storage + backup diesel generator
Intelligent load management to prioritise renewable energy
High efficiency performance in demanding 24/7 operations
This system allowed diesel generation to be used only when absolutely necessary, dramatically reducing run hours.
The Elara deployment delivered measurable benefits within its first month:
98.9% efficiency
$3,550 saved in diesel costs compared to a 24/7 generator setup
4.5 tonnes of CO₂ emissions avoided
Backup diesel generator ran only 4 hours in 30 days
🌱 Environmental Leadership – Substantial reductions in CO₂ emissions showcase how hybrid power can align with sustainable development goals.
💰 Cost Savings – Significant fuel savings even in short deployment windows.
🏗️ Smarter Communities – Clean, quiet power solutions that support large-scale civil projects without compromising efficiency.
By deploying the Makinex HPS20 at Elara, WEM Civil demonstrated that subdivision projects can be powered sustainably, efficiently, and cost-effectively. The results from this 30-day period reinforce the role of hybrid power systems in shaping the future of infrastructure and residential development.
