Technical Integration for the Narrogin Wind Farm Project

The South West Interconnected System requires additional renewable generation capacity to meet the Western Australian Government's target of 82 percent renewable energy by 2030. Integrating intermittent wind power into a major electrical grid demands coordination between generation developers, state energy retailers, primary contractors, and original equipment manufacturers to ensure voltage stability, capacity delivery, and grid code compliance.

Neoen will act as the asset developer and owner, while Synergy, Western Australia's largest state-owned energy retailer, will purchase 100 percent of the generated power at the point of connection. To execute the engineering and construction phases, Neoen issued notices to proceed to Envision Energy as the turbine manufacturer, and to a construction consortium comprising UGL and CPB Contractors for the balance of plant scope.

Infrastructure Layout and Engineering Specifications
Located near Narrogin and Williams, 200 kilometers southeast of Perth, the Narrogin Wind Farm comprises 23 Envision EN182-7.8 megawatt wind turbines. The facility has a total installed capacity of 179 megawatts, yielding a 168 megawatt net output at the point of connection.

The electrical balance of plant involves step-up power transformers, internal underground collector systems, and high-voltage switchgear. Physical interconnection occurs directly via Western Power's existing 220 kilovolt transmission line, routing power across the digital infrastructure and control networks of the South West Interconnected System.

Operational Integration and System Impact
The asset will supply approximately 3 percent of the total annual electricity demand within the South West Interconnected System network. The plant operates alongside existing utility-scale energy storage assets in the region, including the Collie Battery and Muchea Battery facilities, providing frequency stabilization and balance against peak load fluctuations.

From a technical and operational perspective, the facility pairs a 179 megawatt gross installed capacity across 23 Envision EN182-7.8 megawatt units with a direct 220 kilovolt Western Power interconnection. This delivers a reliable 168 megawatt net capacity at the point of connection while supporting over 250 technical and civil roles throughout the construction phase.
