The Indian electricity sector is a centrally planned sector that faces increasing financial stress. In other words, a centrally planned decarbonisation would result in enlarged costs and political difficulties. The path forward for electricity reforms is to make changes one state at a time. We have started this journey with the state of Tamil Nadu.

The case of Tamil Nadu is particularly interesting. It holds great potential when it comes to the energy transition with high potential of offshore wind and solar. However, poor quality of supply along with indiscriminate subsidies for domestic and agricultural consumers has led to deep levels of fiscal stress on the Tamil Nadu state exchequer. Fiscal stress harms investibility in electricity, which is particularly a challenge for renewables. Due to multiple reasons, some of which may be attributed to the political economy at the state level, the state of Tamil Nadu has also revised tariffs only four times since the Electricity Act was enacted in 2003. These tariff revisions have often not reflected the cost of supply of electricity (e.g., the tariff revisions in 2017).

While the electricity sector in Tamil Nadu has recently undergone institutional changes in the form of TANGEDCO’s demerger, the present state of regulatory challenges has not been adequately addressed. In a new paper, Improving electricity regulation in Tamil Nadu, we present evidence on regulatory failures of the electricity regulator in Tamil Nadu (TNERC) and contextualise the impact of this on associated aspects of public finance and private finance. We bring the knowledge of regulatory theory to bear upon the possible causes of these failures. We discuss the TNERC’s performance on elements that make up a well-functioning regulator, such as clarity of purpose, separation of powers, selection of board members, fair adjudication, public consultations and financial independence.

Many aspects of regulatory reform require amendments to the Electricity Act, and hence the problem statement lies in identifying the levers available to make progress in Tamil Nadu. We identify several levers that the state government can use to undertake reforms, well within its powers under the Electricity Act, to make Tamil Nadu a turnaround story and a model for good electricity regulation nationwide. When these improvements are put into motion, they will materially change the views of private investors on the feasibility of investment in the Tamil Nadu electricity sector. This paper offers ideas on how this can be done.
