Synopsis This publication examines in detail the effectiveness and impact of regulatory tariff orders in the distribution segment of the Indian power sector. A comprehensive survey of tariff orders issued by nine state electricity regulatory commissions (Andhra Pradesh, Assam, Delhi, Jharkhand, Kerala, Madhya Pradesh, Maharashtra, Uttarakhand and West Bengal) for the distribution licensees has been undertaken to evaluate the effectiveness of regulatory orders in the electricity sector. This book assesses whether the orders have resulted in reducing regulatory uncertainty and information asymmetry, and led to better performance of the distribution utilities. Different indicators have been used to assess the impact on consumption and access, efficiency, financial performance, competition, and consumer-related issues in the power sector of these states. In addition, various parameters have been studied to assess whether the regulatory systems follow the principles of good regulation in these nine states. This book will be useful for policy-makers, regulators, academics, managers of power utilities, researchers, donors and all those involved in design and implementation of regulatory programmes.
