Viability Gap Funding
"A government grant mechanism that bridges the gap between the cost of providing infrastructure services and the revenue recoverable from users"
Viability Gap Funding (VGF) is a financial support mechanism under which the government provides a one-time or recurring capital grant to make economically justified but financially unviable infrastructure projects bankable. In India, the VGF Scheme was introduced by the Ministry of Finance in 2004 and has since been applied across sectors including highways, airports, ports, railways, and regional aviation. Under the Modified UDAN scheme (2026), VGF bridges the gap between airline operating costs on regional routes and the capped fare revenue, with Rs 10,043 crore allocated over 10 years. VGF typically covers up to 20-40% of total project cost in PPP projects, with the remaining funded through private equity and debt.
VGF is a key PPP and infrastructure concept for UPSC GS-3 (economic development, infrastructure). It appears in the context of UDAN scheme, highway BOT projects, smart cities, and affordable housing. Understanding VGF helps answer questions on public-private partnerships and government intervention in market failures.
- 1 Introduced by Ministry of Finance in 2004 for PPP infrastructure projects
- 2 Covers up to 20% of total project cost as a one-time grant (additional 20% from sponsoring authority)
- 3 Applied in highways, airports, ports, power, railways, and regional aviation
- 4 Under Modified UDAN (2026), VGF of Rs 10,043 crore supports airline operators on unviable regional routes
- 5 Funded through the Regional Connectivity Fund (RCF) in the aviation context, sourced from a levy on flights
- 6 Tapering mechanism used in Modified UDAN — 80-90% VGF initially, reducing over 5 years per route
Under the Modified UDAN scheme, airlines receive VGF support for 5 years per regional route (extended from 3 years in the original scheme), helping bridge the gap between operating costs and capped fares of Rs 2,500 for a one-hour flight.
