International Energy Agency (IEA) - Building the Future Transmission Grid Summary

Introduction

The International Energy Agency (IEA) highlights the urgency to expand and modernize global electricity transmission infrastructure. This report addresses supply chain challenges, price pressures, and lead times for key components, offering actionable recommendations for policymakers and industry stakeholders.

Key Findings

1. Growing Demand: Global electricity consumption is rising by nearly 4% annually through 2027, with renewables accounting for a third of electricity generation.
2. Supply Chain Strain: Lead times for cables and transformers have more than doubled since 2021. Prices for cables have nearly doubled since 2019; transformer prices increased by ~75%. Offshore HVDC cable installation faces extreme delays (up to 5 years).
3. Regional Investments: Advanced economies and China account for ~80% of transmission investment, with a projected $200-300 billion/year required by mid-century under climate goals.
4. Skills Gap: The power grid sector employs ~8 million people globally, with a projected ~1.5 million job gap by 2030 (9.5 million jobs needed vs 8 million in 2023 under STEPS scenario).

Actionable Recommendations

1. Demand Visibility: Enhance transparent, long-term transmission investment plans with credible project pipelines.
2. Procurement Frameworks: Promote long-term agreements and harmonized procurement standards to ensure component availability and affordability.
3. Permitting Reforms: Streamline approval processes, prioritize key infrastructure to reduce project delays.
4. Skills Development: Invest in training and digital skills to address the workforce shortage.
5. Grid Modernization: Leverage digital technologies for grid optimization and utilize existing infrastructure more efficiently.

Conclusion

Addressing supply chain bottlenecks and investing proactively in transmission infrastructure is critical for climate goals and energy security. Enhanced collaboration between governments, manufacturers, and regulators is necessary to meet growing energy demands sustainably.
