Nexa Advisory Submission – New South Wales Transmission Planning Review 2025

Nexa Advisory welcomes the opportunity to share our views and insights as part of the New South Wales Transmission Planning Review 2025.

We have long advocated for the timely and efficient delivery of transmission infrastructure to support Australia’s clean energy transition and deliver energy security, reliability and affordability for electricity consumers. However, transmission delays across New South Wales and the broader National Electricity Market (NEM) continue to undermine renewable energy targets, investor confidence and consumer outcomes.

While the New South Wales framework has attempted to address the key challenges associated with delivering transmission, we consider the complex governance arrangements has contributed to transmission delays in the state.

Additionally, we consider that opening transmission build to established transmission network organisations that demonstrate resource capability, experience in building the infrastructure and procurement leverage is the most effective pathway to overcome ongoing delays and cost blow-outs. This limits the potential inefficiencies and uncompetitive outcomes associated with delivery by the regulated incumbent Transmission Network Service Providers (TNSP).

We urge the New South Wales Government to:

• open the market for competitive delivery of all transmission projects across New South Wales;
• appoint an independent entity such as EnergyCo to be responsible for the planning and coordination of transmission across the state – ensuring the separation of the New South Wales Infrastructure Planner and transmission delivery entity (Network Operator);
• better explore virtual transmission and non-network solutions; and
• uphold transmission and distribution ring-fencing.
