Mokoan Solar Farm

The Mokoan Solar Farm, located in Winton within Victoria’s Hume Region, marks European Energy’s first constructed project in Australia. Spanning 94 hectares, the solar farm reached first power in December 2024 and represents an important step in European Energy’s expansion into the Australian renewable energy market. To support safe and reliable grid connection, Insulect supplied key high‑voltage and medium‑voltage equipment, including 72.5 kV disconnectors, a 72.5 kV dead tank circuit breaker with point‑on‑wave control, 72.5 kV instrument voltage transformers, and 33 kV post insulators.

Challenge

As European Energy’s first Australian build, the Mokoan Solar Farm required a grid connection solution that delivered both reliability and long‑term performance. The project demanded precise control of switching operations, strong insulation performance, and accurate voltage measurement to meet grid compliance requirements. With tight construction timelines and commissioning milestones, the risk of delays or equipment incompatibility needed to be minimised while ensuring the solar farm could operate safely and efficiently once connected to the network.

Solution

Insulect worked closely with the project team to supply a coordinated package of electrical equipment tailored to the site’s requirements. The 72.5 kV disconnectors and dead tank circuit breaker with point‑on‑wave control provided safe, controlled switching at the point of grid connection. Instrument voltage transformers ensured accurate measurement for protection and control systems, while robust 33 kV post insulators delivered dependable mechanical and electrical support throughout the installation. By supplying compatible equipment across voltage levels, Insulect helped simplify integration and installation onsite.

Benefits

The integrated solution reduced project complexity and supported a smooth construction and commissioning process. Controlled switching helped minimise electrical stress on equipment, while accurate measurement supported grid compliance and operational confidence. Using proven, high‑quality components also supported long‑term reliability, reducing the risk of unplanned outages and ongoing maintenance demands. Insulect’s involvement provided European Energy with confidence that its first Australian project was built on a solid and dependable electrical foundation.

Results

With Insulect’s equipment in place, the Mokoan Solar Farm successfully achieved first power in December 2024 and has progressed into commissioning and grid compliance testing, with full operation planned for 2025. The project stands as a successful introduction of European Energy into the Australian market and demonstrates Insulect’s capability to support large‑scale renewable projects with reliable, well‑engineered solutions that help bring clean energy assets online safely and efficiently.
