Global Grid Modernization and Transmission Infrastructure Investment Market Strategic Report, 2026-2031 | AI Data Centers and Renewables Fuel 11.4% CAGR to $545 Billion by 2031

Dublin, Oct. 19, 2026 -- "Global Grid Modernisation & Transmission Infrastructure Investment Market Strategic Research Report" has been added to ResearchAndMarkets.com's offering.

The global grid modernization and transmission infrastructure investment market has entered a structural supercycle, supported by rising electricity demand, aging infrastructure, renewable energy deployment and rapid growth in AI data center electricity consumption. Valued at USD 250 billion in 2025, the market is forecast to expand at a CAGR of 11.4% and reach USD 545 billion by 2031.

This acceleration reflects a fundamental shift in utility and infrastructure investment priorities. Aging grid infrastructure replacement cycles remain important, but capital spending is increasingly directed toward expanding transmission capacity, modernizing distribution networks, integrating energy storage and deploying smart grid technology. Utilities, governments and infrastructure investors must also address the growing volume of renewable energy projects awaiting interconnection.

The convergence of structural demand drivers -- decarbonization-driven renewable interconnection, electrification of transport and heating, and now AI-driven data center load growth -- represents a genuinely new capital investment cycle distinct from prior grid infrastructure spending waves, which were driven primarily by aging-asset replacement alone.

Power demand from cloud computing, artificial intelligence and hyperscale data centers is placing additional pressure on electricity networks in major global markets. These facilities require dependable, high-capacity power supplies, creating demand for new transmission corridors, substation upgrades, distribution system expansion and improved grid resilience. At the same time, electric vehicle adoption and the electrification of residential, commercial and industrial heating are changing load profiles and increasing the need for flexible grid management.
