Hybrid Renewable Energy Powering Holcim’s Mobile Concrete Plants
How hybrid renewable energy is transforming concrete supply on remote infrastructure projects
Holcim is supporting major transmission infrastructure across New South Wales, including HumeLink and installations across the Central West Orana Renewable Energy Zone (REZ).
HumeLink is a new transmission line connecting Wagga Wagga, Bannaby and Maragle across regional NSW, strengthening the state’s electricity network and supporting the transition to renewable energy.
To enable these projects in remote locations, Holcim has deployed renewable-powered, hybrid mobile concrete plants that deliver reliable production while significantly reducing fuel use and emissions.
Hybrid renewable energy is enabling Holcim to deliver low-emissions concrete supply for remote transmission infrastructure projects across New South Wales.
On-site solar generation forms a key part of Holcim’s hybrid renewable energy system, reducing fuel use and emissions at remote project sites.
Holcim currently has three hybrid mobile plants in service, with additional plants set to go in the coming months to support transmission projects and other works across the network.
Each plant operates on a hybrid renewable energy system combining solar, battery storage and generators. In most situations, solar is the primary power source, with batteries supporting continuous operation and generators used only when required.
This approach has reduced generator run times to between 14 and 20 hours per month, while still supplying power 24 hours a day.
December performance data highlights the impact of this configuration:
- Central West Orana and HumeLink East sites avoided over 10 tonnes of CO₂ in a single month
- Solar power generation exceeded or closely matched generator power usage
- Thousands of litres of diesel were saved across sites
Beyond environmental benefits, the hybrid systems are improving day-to-day site conditions.
Running our mobile plants in this configuration not only enables us to offer a more sustainable way of making concrete in rural areas, it’s also delivered great feedback from our operational teams. Having power available 24 hours a day and reducing generator noise makes a real difference on site.
Holcim ready-mix concrete, engineered to reduce CO₂ impact while delivering strength and reliability.
Exploring renewable energy solutions and reducing CO₂ intensity across operations is a key pillar of Holcim’s NextGen growth strategy, helping customers reduce emissions on major infrastructure projects while maintaining productivity and reliability.
Holcim’s hybrid mobile plants are delivered in partnership with Blue Diamond (battery systems and generators) and Makinex Renewables (solar solutions), ensuring strong performance today and into the future.
