In the aftermath of the nuclear leaks in Japan, there have been concerns regarding the safety of nuclear power plants around the world. There are some proposals to change the regulatory framework in India to ensure the safety of these plants. We examine some of the issues in the current structure. Which body looks at safety issues regarding nuclear power plants in the country? The apex institution tasked to look at issues regarding nuclear safety is the Atomic Energy Regulatory Board. The AERB was set up in 1983 to carry out regulatory and safety functions regarding nuclear and radiation facilities. The agency has to give clearances for establishing nuclear power plants and facilities. It issues clearances for nuclear power projects in stages after safety reviews. The safety of setting up a nuclear plant in any given area is also assessed by the AERB. For example, it would have looked into the safety of setting up a nuclear power project in Jaitapur in Maharashtra. AERB also reviews the safety mechanisms within existing nuclear plants and facilities. To do this, it requires nuclear facilities to report their compliance with safety regulations, and also makes periodic inspections. Under the recently passed Civil Liability for Nuclear Damage Act, 2010 the AERB is also the authority responsible for notifying when a nuclear incident takes place. Mechanisms for assessing and claiming compensation by victims will be initiated only after the nuclear incident is notified. Why is the Atomic Energy Regulatory Board in the news? Prime Minister Manmohan Singh announced on March 29, 2011, "We will strengthen the Atomic Energy Regulatory Board and make it a truly autonomous and independent regulatory authority." This announcement came in the backdrop of the continuing crisis and high radiation levels at the Fukusima nuclear plant in Japan. News reports opined that the lack of proper autonomy of Japan's nuclear regulator curbed its effectiveness. Japan's ministry of economy, trade and industry regulates the nuclear power industry, and also promotes nuclear technology. These two aims work at cross-purposes. India's regulatory structure is similar to Japan in some respects. What measures has the AERB taken post the Fukushima nuclear incident in Japan? Following the nuclear incident in Japan, a high-level committee under the chairmanship of a former AERB chairman has been set up to review the safety of Indian nuclear power plants. The committee shall assess the capability of Indian nuclear power plants to withstand earthquakes, tsunamis, cyclones, floods, etc. The committee will review the adequacy of provisions for ensuring safety in case of such events. Is there any issue in the current regulatory structure? The AERB is a regulatory body, which derives administrative and financial support from the Department of Atomic Energy. It reports to the secreatry, DAE. The DAE is also involved in the promotion of nuclear energy, and is also responsible for the functioning of the Nuclear Power Corporation of India Limited, which operates most nuclear power plants in the country. The DAE is thus responsible both for nuclear safety (through the AERB), as well as the operation of nuclear power plants (through NPCIL). This could be seen as a conflict of interest. How does the system of independent regulators differ from this? The telecom sector provides an example of an independent regulator. The Telecom Regulatory Authority of India does not report to the Department of Telecommunications. The DoT is responsible for policy matters related to telecommunications, promoting private investment in telecom, and also has a stake in BSNL. Had TRAI reported to the DoT, there would have been a conflict of interest within the DoT. What will the proposed legislation change? Recent news reports have stated that a bill to create an independent regulatory body will be introduced in Parliament soon. Though there is no draft bill available publicly, news reports state that an independent Nuclear Regulatory Authority of India will be created by the bill, and the authority will subsume the AERB within it.

Last week, the Power Finance Corporation reported that state-owned power distribution companies across the country made financial losses amounting to Rs 68,832 crore in 2022-23. This is four times higher than the losses witnessed in 2021-22, and roughly equivalent to the annual budget of a state like Uttarakhand. This blog examines some of the causes and implications of such losses.
Overview of financial losses
For several years now, electricity distribution companies (discoms), which are mostly state-owned, have witnessed steep financial losses. Between 2017-18 and 2022-23, losses accumulated to over three lakh crore rupees. In 2021-22, discom witnessed substantial reduction in their losses, primarily because states released 1.54 lakh rupees in subsidies to clear pending dues. State governments provide discoms with subsidies, so that domestic and agricultural consumers receive affordable power. These payments are typically delayed which creates cash flow constraints, and leads to an accumulation of debt. In addition, costs incurred by discoms in 2021-22 remained unchanged.
Note: Data from 2020-21 onwards does not include Odisha, and Dadra & Nagar Haveli and Daman and Diu since their distribution function was privatised in 2020-21. Data for Ladakh is available from 2021-22 onwards. Data for Jammu and Kashmir is not available. The Delhi Municipal Council Distribution Utility has been included from 2020-21 onwards.

As of 2022-23, losses have increased again to reach Rs 68,832 crore. This increase has been driven by rising costs. At a per unit level, the cost of supplying one kilowatt of electricity rose from 7.6 rupees in 2021-22, to 8.6 rupees in 2022-23 (See Table 1).

Purchase of electricity from generation companies (gencos) forms about 70% of a discom’s total costs, and coal is the primary source for generating electricity. The following chain of events took place in 2022-23: (i) consumer demand for electricity rose by 10% over the previous year, as compared to a 6% year-on-year increase in the past 10 years, (ii) coal had to be imported to meet the increased demand, and (iii) global coal prices were elevated.
Coal imported at elevated prices to keep up with rising electricity demand
In 2022-23, demand for electricity increased by 10% over 2021-22. Between 2008-09 and 2018-19, demand increased at an annual growth rate (CAGR) of 6%. Electricity demand grew as the economy grew (at 7%), and largely came from domestic and agricultural consumers. These consumer categories account for 54% of the total electricity sales, and their demand rose by 7%.

Electricity cannot be stored at scale, which means that generation must be scheduled depending on anticipated demand. The Central Electricity Authority anticipates annual demand for each year. It estimated that demand in 2022-23 would be at 1,505 billion units. However, the actual demand was higher than anticipated in the first few months of 2022-23 (See Figure 3).
To meet this demand, electricity generation had to be ramped up. Coal stocks had already depleted from 29 million tonnes in June 2021 to eight million tonnes in September 2021, on account of high demand in 2021-22. To ensure uninterrupted supply of power, the Ministry of Power directed gencos to import coal. The Ministry noted that without imports, widespread power cuts and blackouts would have occurred.
Sources: Load Generation Balance Report 2022 and 2023, Central Electricity Authority; PRS.
Coal imports rose by about 27 million tonnes in 2022-23. While this constituted only 5% of the overall coal used in the sector, the price at which it was imported significantly impacted the sector. In 2021-22, India imported coal at an average price of Rs 8,300 per tonne. This rose to Rs 12,500 per tonne in 2022-23, a 51% increase. Coal was primarily imported from Indonesia, and prices shot up due to the Russia-Ukraine war, and demand surge by countries like India and China.

Coal import situation going forward
In January 2023, the Ministry of Power advised gencos to import 6% of the required coal, to ensure sufficient stock until September 2023. It noted that due to floods and variable rainfall in various parts of the country, hydro generation capacity reduced by about 14%. This put additional burden on coal based thermal generation in 2023-24. Following this, in October 2023, the Ministry directed all gencos to continue using at least 6% imported coal until March 2024.

Structural issues in the power sector and its impact on state finances
Discoms witness persistent financial losses due to certain structural issues. Their costs are typically high because of old contracts with generation companies (gencos). Power purchase costs in these contracts do not account for production efficiencies over the years, and costs remain unchanged. Tariffs are only revised every few years, to ensure that consumers are protected from supply chain shocks. As a result, costs are carried forward for a few years. In addition, discoms sell electricity to certain consumers such as agricultural and residential consumers, below cost. This is supposed to primarily be recovered through subsidy grants provided by state governments. However, states often delay subsidy payments leading to cash flow issues, and accumulation of debt. In addition, tariff recovery from the power sold is not optimal.
Losses reported in the generation sector have also increased. In 2022-23, state-owned gencos reported losses worth Rs 7,175 crore, as compared to the Rs 4,245 crore in 2021-22. Rajasthan accounted for 87% of these, at Rs 6,278 crore. Note that under the Late Payment Surcharge Rules, 2022, discoms are required to make upfront payments to gencos.
Risk to state finances
Persistent financial losses, high debt and guarantees extended by states continue to pose a risk to state finances. These are contingent liabilities for state governments, i.e., in the event a discom is unable to repay its debt, the state would have to take it over.
Several such schemes have been introduced in the past to bail discoms out (See Table 2). As of 2022-23, discoms have an outstanding debt worth Rs 6.61 lakh crore, 2.4% of the national GDP. Debt is significantly high in states such as Tamil Nadu (6% of GSDP), Rajasthan (6% of GSDP), and Uttar Pradesh (3% of GSDP). Previous Finance Commissions have recognised that strengthening discom finances is key in minimising the risk to state finances.
