National Highways Authority of India is exploring a renewed emphasis on the Build-Operate-Transfer (BOT) model as part of its highway monetisation programme, industry sources say. Reports indicate that a revival of the BOT approach could generate about Rs 200 billion (bn) in additional receipts, strengthening NHAI's financial position and supporting future infrastructure investment. The potential boost comes as authorities seek to diversify funding for large-scale road projects. Over recent years NHAI relied on a mix of toll-operate-transfer transactions, infrastructure investment trusts and borrowings alongside budgetary support to finance construction and upkeep. The Build-Operate-Transfer model allows private developers to finance, build, operate and maintain roads for a fixed concession period before transferring assets back to the government. Renewed investor interest reflects improving traffic volumes, stronger economic growth and more balanced risk-sharing arrangements that reduce developer exposure. Officials expect that expanding BOT projects will ease the fiscal burden on public agencies while accelerating project delivery, since private partners provide capital at the outset and recover costs via toll collections and concession revenues. The approach is poised to complement NHAI's asset monetisation strategy as mature highway assets generate predictable revenue streams that attract institutional investors. Encouraging private participation at both construction and operational stages could create a more resilient infrastructure financing ecosystem. Market participants have pointed to lower execution risks and improved project structuring as factors that make highway investments more attractive to domestic and international firms. A larger BOT pipeline may unlock fresh capital and broaden monetisation options, potentially enabling NHAI to surpass existing realisation targets. If adopted at scale the combined strategy of asset recycling and greater private involvement could mark a notable evolution in the financing of road infrastructure.
