CANBERRA, Australia, Feb 26, 2026 – Siemens, in partnership with Mescada, will deploy cloud-based SCADA systems for Global Power Generation Australia (GPGA) to manage 1GW of renewable energy capacity across Australia. GPGA operates wind farms, hybrid solar and storage sites, and Battery Energy Storage System (BESS) projects. The cloud-based SCADA platform will centralize monitoring and control of these distributed energy assets.
Siemens will connect eight renewable energy generation and storage sites across New South Wales, Victoria, Western Australia, and the Australian capital territory using its AI-enabled Simatic WinCC Open Architecture SCADA platform. The system will process about 300,000 data tags and provide real-time monitoring and control from a centralized control room in Canberra. In the second phase, it will integrate with the Australian Energy Market Operator (AEMO), enabling operators to respond to grid and market signals.
GPGA’s chief operations officer Gema Deus Vazquez said, “The installation of a centralised SCADA system is a significant step forward in our ambitions to scale renewable power generation in Australia, using the best-in-class technology that’s future-ready. As we grow and diversify our renewable energy portfolio in the country, we need robust systems that help build energy resilience, integrate seamlessly into national energy networks and are AI-ready for future. The combination of Mescada’s expertise and Siemens technology ticks all the right boxes and is a big step forward in our growth and sustainability journey.”
As GPG expands renewable capacity from 1.4GW to 3GW, the control platform will scale with that growth. The deployment brings multiple renewable sites under a single operating structure. The platform will incorporate generative AI for operator assistance and use smart node technology to connect external data sources and APIs within the SCADA environment.
“This project sets a new standard for the renewable energy industry in Australia and demonstrates the power of combining our proven SCADA technology with cloud infrastructure,” said Darryl Kaufmann, head of Digital Industries at Siemens Australia and New Zealand. “By unifying control across eight sites with different legacy systems, we’ve created a scalable, future-ready platform that will support GPGA’s ambitious growth plans while ensuring compliance with critical grid regulations. As Australia accelerates energy transition, this project demonstrates how advanced SCADA technology can support grid stability and increase energy security and operational excellence across distributed generation assets. It is also a great example of how, through collaboration, we can all play a part in going beyond just addressing the one percent of emissions Australia is responsible for.”
The deployment addresses key challenges facing renewable energy operators in Australia:
- Multi-site integration: The system aggregates data from eight power plants with different SCADA systems and communication protocols, providing operators with an interface across all sites
- Scalability: The cloud-based architecture is designed to support GPGA’s expansion plan
- Operational efficiency: Centralized monitoring and control reduces downtime, improves decision-making, and enhances operational efficacy and profitability
- Regulatory compliance: In the second stage, the system will integrate with AEMO to respond to grid and market requests, avoid noncompliance penalties, and track market prices
Hung Chan, CEO of Mescada, said, “Deploying Australia’s first large-scale cloud-based SCADA system for renewable energy requires navigating significant technical complexity, from integrating multiple, geographically dispersed legacy systems to ensuring seamless AEMO compliance. As Siemens’ automation solution partner for Australia, through the years, we’ve delivered several benchmark projects that accelerated digitalization through technology. This project for Global Power Generation Australia is particularly significant for what we have achieved using SCADA technology at a scale that’s never been seen in the renewable energy sector in Australia. The result is a truly future-ready platform that will support Australia’s renewable energy transition for years to come.”
