Market Size and Growth

The global power transmission and distribution EPC market was valued at US$ 240.2 billion in 2024 and is projected to reach US$ 377.7 billion by 2035, reflecting a steady CAGR of 4.2% between 2025 and 2035. This forecasted growth underscores strong underlying demand for new transmission lines, substation upgrades, grid modernization initiatives, and rural electrification programs. Rising electricity load profiles, increasing grid complexity, and deployment of renewable energy projects-many of which require new trunk transmission capacity-are major drivers of EPC service demand. Additionally, the market is benefiting from public and private sector investments aimed at mitigating grid instability, reducing technical losses, and strengthening national resilience against climate-related disruptions and cyber threats.

Market Segmentation

The market is broadly segmented by project type, with Transmission Projects accounting for 63% of total revenue in 2024. This dominance stems from large-scale interconnection projects, high-voltage AC and DC line expansions, and cross-border transmission initiatives designed to improve power exchange and optimize renewable generation. Distribution EPC projects, while smaller in scope, are gaining importance due to rapid urban development, smart meter deployment, and the growing need to modernize aging low-voltage infrastructure. Additional segmentation by voltage level, service type, and end-use sectors further highlights the diverse range of EPC projects underway globally-from industrial grid expansion projects to utility-scale renewable integrations and rural electrification schemes in emerging economies.

Regional Analysis

The Asia Pacific region held the largest market share at 48.2% in 2024, making it the dominant global hub for power transmission and distribution EPC activity. This leadership position is driven by large-scale infrastructure programs in China, India, and Southeast Asia, where expanding industrial bases, rapid population growth, and massive renewable deployment have created substantial grid development needs. North America and Europe continue to invest heavily in grid modernization, renewable energy interconnection, and replacement of aging assets, driven by policy mandates and climate resilience goals. Meanwhile, regions such as the Middle East, Africa, and Latin America are witnessing accelerating demand for electrification and transmission expansion, creating significant opportunities for EPC contractors and technology providers.
