Corvus required confirmation that Ergon’s existing 66kV Lilyvale feeder could support a new underground coal mine development.

The network already supplied multiple mines and the township of Emerald, creating risk of capacity constraints, future demand conflicts and potential capital upgrades.

Early clarity was critical to avoid costly redesign and schedule delays.

Waterline delivered a structured electrical feasibility assessment to validate network capacity and de-risk early project decisions.

Our work included detailed review and rationalisation of the mine load profile, a high-level maximum demand assessment of the Lilyvale feeder, and modelling of staged ramp-up alongside known future regional demand.

Where constraints were identified, we developed practical alternate connection options, supported by a clear traffic-light feasibility framework and high-level concept sketches.

Throughout the study, our focus extended beyond technical compliance, integrating capital efficiency, delivery timeframe and risk exposure to ensure recommendations were commercially sound as well as technically robust.

Corvus gained early visibility of potential network constraints, enabling informed decision-making before capital was committed.

By validating feeder capacity and identifying practical connection alternatives upfront, the project avoided unnecessary upgrade exposure and late-stage redesign risk.

The result was a commercially viable connection strategy aligned with staged mine development and future regional demand.

With a clear, evidence-based pathway forward, Corvus engaged the supply authority with greater confidence and progressed the project on a structured, low-risk footing.

Project Overview

The Corvus 66kV Electrical Infrastructure project is a pivotal initiative designed to enhance the electrical capacity required for new underground coal mining operations. This project addresses the critical need for a reliable power supply to support ongoing and future mining activities in the region.

Waterline Projects undertook a comprehensive review of the existing electrical feeder's capacity, leading to informed decisions on necessary upgrades and modifications. By ensuring that the infrastructure meets the growing demands of the coal mining sector, the project aims to facilitate sustainable energy solutions that align with industry standards.

Challenges Faced

Throughout the Corvus project, various challenges emerged, particularly regarding the existing electrical infrastructure's ability to support increased loads. Identifying these constraints was crucial for developing viable solutions that would not only meet current demands but also anticipate future growth.

Key challenges included assessing the maximum demand on the Lilyvale feeder and understanding how regional demand growth would impact the system. Waterline Projects employed advanced modeling techniques to evaluate these factors, ensuring that all potential risks were addressed in the project planning phase.

Proposed Solutions

To overcome the identified challenges, Waterline Projects developed a range of practical alternate connection options. These solutions were designed to enhance the electrical infrastructure's capacity while ensuring compliance with technical and regulatory requirements.

The proposed solutions included a traffic-light feasibility framework that allowed stakeholders to visualize potential outcomes and risks. This structured approach not only facilitated better decision-making but also provided a clear pathway for project progression, ensuring that all recommendations were both commercially viable and technically sound.

Successful Outcomes

The successful completion of the Corvus 66kV Electrical Infrastructure project has led to significant advancements in the region's electrical capabilities. By addressing the initial challenges and implementing robust solutions, Waterline Projects has set a precedent for future projects in the electrical infrastructure sector.

As a result of the project, Corvus has established a strong working relationship with the supply authority, allowing for more confident engagement in future developments. The project not only met its technical objectives but also demonstrated Waterline's commitment to delivering high-quality engineering solutions that support the growth of the coal mining industry.
