Building renewable energy transmission infrastructure

Why this is important

Transmission projects need to be delivered effectively and economically for Victoria to meet its renewable energy targets and energy objectives.

Transmission infrastructure is critical because it enables new renewable generation to connect to the grid and deliver electricity where it is needed. Without timely investment and delivery of new transmission infrastructure, Victoria risks a disorderly transition to renewable energy as coal-fired power stations close.

VicGrid is now fully responsible for planning and delivering Victoria’s renewable energy transmission network. By 2028–29, Western Renewables Link and the first 2 projects to be fast tracked under the Victorian Transmission Plan should be nearly completed.

Our 2025 audit of Victoria's transition to renewable energy highlighted considerable delays and higher than expected costs delivering key transmission projects. Given these significant delivery risks, it is important that Victorians have assurance about the government’s progress in implementing the Victorian Transmission Plan.

What we plan to examine
