The cost of equity capital is a key input used by regulators to fix permissible rates of return and determine regulated tariffs. Investors also need an appropriate hurdle rate to make investment decisions. Regulators worldwide often use a single-factor model to estimate the cost of equity. The empirical literature shows that such a model has limited efficacy in explaining stock returns, while other factors also capture the risk involved in the market. This study is perhaps the first to apply three asset pricing models—the capital asset pricing model (CAPM) and the Fama-French three- and five-factor models—to estimate the cost of equity for the Indian energy and infrastructure sectors. We find that the reasonable rate of return fixed by the respective regulator based on the CAPM is often higher than this study's estimated cost of equity (using CAPM). The spread between the regulated return across the identified energy and infrastructure sectors is estimated using a single-factor model, and our estimation using the three-factor model is relatively lower. The spread increases when we apply the recent five-factor model for regulated utilities. The study can guide policymakers and regulators in estimating and fixing reasonable rates of return for the infrastructure sectors. • Estimation of cost of equity using the three asset pricing models for publicly listed Indian energy and infrastructure firms. • Applications of three asset pricing models: the capital asset pricing model, Fama-French three-and five-factor models. • A review of framework regulated return across key energy and infrastructure sectors. • The regulated rate of return set by the respective regulator is found to be higher, in general, than those estimated in this paper.
