Correcting Market Failure: An Analysis of India’s Solar Energy Market

Abstract

India’s growing electricity demand and continued dependence on coal have created significant environmental and economic challenges. Coal-based electricity generation produces negative externalities, including air pollution, health-related costs and carbon emissions, resulting in a divergence between private and social costs and creating allocative inefficiency. In response, the Government of India has introduced several policies to promote solar energy, including subsidies, production-linked incentives, Renewable Purchase Obligations and other financial and regulatory measures. This paper evaluates the extent to which these interventions have corrected market failure and improved allocative efficiency in India’s electricity market. The analysis first applies microeconomic concepts of negative and positive externalities, marginal private and social costs, allocative efficiency, welfare loss and corrective subsidies to establish the theoretical basis for government intervention. It then applies these concepts to India using evidence on coal dependence, solar capacity growth and changes in renewable-energy costs. The paper further evaluates the effectiveness of government intervention by examining whether the expansion of solar energy has shifted electricity production towards a more socially efficient outcome. Finally, the analysis considers broader macroeconomic and long-term factors, including the fiscal cost of subsidies, energy security, dependence on imported solar technology and critical minerals, trade implications, storage requirements and the risk of government failure. The findings suggest that government intervention has partially corrected the market failure by increasing incentives for renewable-energy investment, lowering the relative cost of solar power and encouraging a shift towards cleaner electricity generation. However, the continued dominance of coal, fiscal and infrastructure constraints, and dependence on imported components indicate that allocative efficiency has not yet been fully achieved. Therefore, India's solar-energy policies represent a significant movement towards a more socially efficient energy market, but their long-term effectiveness depends on reducing structural constraints and ensuring that government support becomes increasingly targeted and economically sustainable.
