Accelerating the electric grid for a net-zero future: A GHD report

Electricity transmission networks are the essential enablers of the clean energy transition, connecting renewable generation sources to the people and industries that need it. But while renewable generation expansion surges ahead, transmission networks are becoming a critical bottleneck. This gap threatens power reliability and the entire decarbonisation ecosystem - including the production of future fuels like hydrogen and sustainable aviation fuel (SAF). To meet net-zero goals, transmission network expansion and reinforcement must become urgent infrastructure project priorities.

The transmission sector’s ability to scale is being held back by systemic supply chain constraints, regulatory delays, growing community concerns and increasing energy demands. Lead times for critical equipment are stretching into years, forcing a shift toward early, strategic procurement purely to stay on schedule. Meanwhile, complex permitting processes and a lack of genuine community engagement continue to stall progress, even as energy demand surges from electrification and emerging technologies. Without urgent reform and investment, these bottlenecks will undermine the energy transition and stall decarbonisation efforts.
