In the past few months, retail prices of petrol and diesel have consistently increased and have reached all-time high levels. On September 24, 2018, the retail price of petrol in Delhi was Rs 82.72/litre, and that of diesel was Rs 74.02/litre. In Mumbai, these prices were even higher at Rs 90.08/litre and Rs 78.58/litre, respectively.
The difference in retail prices in the two cities is because of the different tax rates levied by the respective state governments on the same products. This blog post explains the major tax components in the price structure of petrol and diesel and how tax rates vary across states. It also analyses the shift in the taxation of these products, its effect on retail prices, and the consequent revenue generated by the central and state governments.
What are the components of the price structure of petrol and diesel?
Retail prices of petrol and diesel in India are revised by oil companies on a daily basis, according to changes in the price of global crude oil. However, the price paid by oil companies makes up 51% of the retail price in case of petrol, and 61% in the case of diesel (Table 1). The break-up of retail prices of petrol and diesel in Delhi, as on September 24, 2018, shows that over 45% of the retail price of petrol comprises central and states taxes. In the case of diesel, this is close to 36%.
At present, the central government has the power to tax the production of petroleum products, while states have the power to tax their sale. The central government levies an excise duty of Rs 19.5/litre on petrol and Rs 15.3/litre on diesel. These make up 24% and 21% of the retail prices of petrol and diesel, respectively.
While excise duty rates are uniform across the country, states levy sales tax/value added tax (VAT), the rates of which differ across states. The figure below shows the different tax rates levied by states on petrol and diesel, which results in their varying retail prices across the country. For instance, the tax rates levied by states on petrol ranges from 17% in Goa to 39% in Maharashtra.
Note that unlike excise duty, sales tax is an ad valorem tax, i.e., it does not have a fixed value, and is charged as a percentage of the price of the product. This implies that while the excise duty component of the price structure is fixed, the sales tax component is charged as a proportion of the price paid by oil companies, which in turn depends on the global crude oil price. With the recent increase in the global prices, and subsequently the retail prices, some states such as Rajasthan, Andhra Pradesh, West Bengal, and Karnataka have announced tax rate cuts.
How have retail prices in India changed vis-à-vis the global crude oil price?
India’s dependence on imports for consumption of petroleum products has increased over the years. For instance, in 1998-99, net imports were 69% of the total consumption, which increased to 93% in 2017-18. Because of a large share of imports in the domestic consumption, any change in the global price of crude oil has a significant impact on the domestic prices of petroleum products. The following figures show the trend in price of global crude oil and retail price of petrol and diesel in India, over the last six years.
The global price of crude oil (Indian basket) decreased from USD 112/barrel in September 2012 to USD 28/barrel in January 2016. Though the global price dropped by 75% during this period, retail prices of petrol and diesel in India decreased only by 13% and 5%, respectively. This disparity in decrease of global and Indian retail prices was because of increase in taxes levied on petrol and diesel, which nullified the benefit of the sharp decline in the global price. Between October 2014and June 2016, the excise duty on petrol increased from Rs 11.02/litre to Rs 21.48/litre. In the same period, the excise duty on diesel increased from Rs 5.11/litre to Rs 17.33/litre.
Over the years, the central government has used taxes to prevent sharp fluctuations in the retail price of diesel and petrol. For instance, in the past, when global crude oil price has increased, duties have been cut. Since January 2016, the global crude oil price has increased by 158% from USD 28/barrel to USD 73/barrel in August 2018. However, during this period, excise duty has been reduced only once by Rs 2/litre in October 2017. While the central government has not signalled any excise duty cut so far, it remains to be seen if any rate cut will happen in case the global crude oil price rises further. With US economic sanctions on Iran coming into effect on November 4, 2018, India may face a shortfall in supply since Iran is India’s third largest oil supplier. Moreover, Organization of Petroleum Exporting Countries (OPEC) and Russia have not indicated any increase in supply from their side yet to offset the possible effect of sanctions. As a result, in a scenario with no tax rate cut, this could increase the retail prices of petrol and diesel even further.
How has the revenue generated from taxing petroleum products changed over the years?
As a result of successive increases in excise duty between November 2014 and January 2016, the year-on-year growth rate of excise duty collections increased from 27% in 2014-15 to 80% in 2015-16. In comparison, the growth rate of sales tax collections was 6% in 2014-15 and 4% in 2015-16. The figure below shows the tax collections from the levy of excise duty and sales tax on petroleum products. From 2011-12 to 2017-18, excise duty and sales tax collections grew annually at a rate of 22% and 11%, respectively.
How is this revenue shared between centre and states?
Though central taxes are levied by the centre, it gets only 58% of the revenue from the levy of these taxes. The rest 42% is devolved to the states as per the recommendations of the 14th Finance Commission. However, excise duty levied on petrol and diesel consists of two broad components – (i) excise duty component, and (ii) road and infrastructure cess. Of this, only the revenue generated from the excise duty component is devolved to states. Revenue generated by the centre from any cess is not devolved to states.
The cess component was increased by Rs 2/litre to Rs 8/litre in the Union Budget 2018-19. However, this was done by reducing the excise duty component by the same amount, so as to keep the overall rate the same. Essentially this provision shifted the revenue of Rs 2/litre of petrol and diesel from states’ divisible pool of taxes to the cess revenue, which is entirely with the centre. This cess revenue is earmarked for financing infrastructure projects.
At present, of the Rs 19.5/litre excise duty levied on petrol, Rs 11.5/litre is the duty component, and Rs 8/litre is the cess component. Therefore, accounting for 42% share of states in the duty component, centre effectively gets a revenue of Rs 14.7/litre, while states get Rs 4.8/litre. Similarly, excise duty of Rs 15.3/litre levied on diesel consists of a cess component of Rs 8/litre. Thus, excise duty on diesel effectively generates revenue of Rs 12.2/litre for the centre and Rs 3.1/litre for states.
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.
