Generation isn’t the bottleneck — the grid is
Australia has underwritten a record pipeline of renewable generation and storage. Connecting it to customers is now the hard part. What governments and utilities should plan for.
- The Capacity Investment Scheme now supports around 13 GW of renewable generation — but projects still need wires to reach customers.
- Grid connection has become the primary constraint, with some developers reporting waits of up to five years.
- Early, well-evidenced connection planning is now one of the biggest controllable risks on any program.
Australia’s energy policy has done what it set out to do on generation. The federal Capacity Investment Scheme (CIS) has backed 65 projects and now supports a pipeline representing around 13 GW of renewable capacity, part of a broader goal of 40 GW of new generation and storage and an 82 per cent renewable grid by 2030.
The problem is no longer whether projects get built. It is whether they can be connected.
A grid built for a different system
The transmission network was designed around a handful of large coal stations. Renewable energy zones are often in different places, and the network is struggling to absorb the volume of wind, solar and battery projects seeking access. Developers now report that securing a grid connection can take up to five years, and industry leaders warn that connecting the CIS pipeline requires a major expansion of high-voltage transmission — currently slowed by planning delays, community opposition and rising material costs.
Supply chains add pressure. Australian projects compete with Europe and North America for HVDC cable, specialised transformers and battery cells, extending lead times and lifting costs.
Policy is shifting toward the network
The federal Rewiring the Nation program provides low-cost public finance for major transmission projects such as VNI West and Marinus Link, aiming to reduce congestion and curtailment. Governments are also working with the Australian Energy Market Operator to streamline approvals. These are the right moves — but they operate on infrastructure timescales of years, not months.
What this means for public and enterprise buyers
For agencies, councils, utilities and large energy users, the practical implication is that the connection pathway should be treated as a core workstream from day one, not a late-stage engineering task.
- Screen sites for network capacity first. Early hosting-capacity and constraint analysis avoids committing to locations the network cannot serve.
- Build connection time into the business case. Programs that assume rapid connection risk stranded capital and missed targets.
- Pair generation with storage. Co-located batteries can reduce curtailment and strengthen the connection application.
- Engage the network service provider early. Clear, well-documented technical submissions shorten the iteration cycle.
The NETS view
The next phase of the energy transition will be won or lost on grid integration. Programs that bring network, regulatory and delivery expertise together at the feasibility stage will connect sooner, spend less and deliver the outcomes their funders expect.
