Transmission infrastructure investment to reach $573.7b by 2030

This growth is supporting the rise in smart grid demand.

Investment in transmission infrastructure is seen to hit $573.7b by 2030 from $372.6b in 2025, with a compound annual growth rate of 9.2% between 2025 and 2030.

According to GlobalData, “the growth in transmission infrastructure investment is accelerating to meet the rising smart grid demand, with the power transmission market expected to expand strongly through the 2030s.”

This growth is being driven by government initiatives, renewable energy integration, the need for greater grid resilience and efficiency, and the adoption of technologies like smart metres, artificial intelligence (AI), and the Internet of Things (IoT).

“AI is improving smart grids by using real-time data and algorithms for demand forecasting, predictive maintenance, and integrating renewables. It optimises power flow, balances supply and demand, automates responses to instabilities, and prevents equipment failures—leading to fewer outages, less energy waste, and a more reliable, sustainable grid,” said Rehaan Shiledar, Power Analyst at GlobalData.

The expert said data centres are playing a crucial role in the functioning and evolution of smart grids due to their significant energy demands and the integration of advanced technologies.

Utilising technologies like microgrids, energy storage systems, and grid-interactive uninterruptible power supplies will allow data centres to refine their energy consumption, increase carbon consciousness, and proactively aid in creating a stable, resilient, and sustainable power infrastructure, Shiledar said.
