Coal for Electricity Generation in India

The paper discusses the commitment on climate change negotiations and reflects why thermal power plants are not replaceable by renewables. It gives a glimpse on electricity demand and supply as well as coal availability. Accordingly, we formulate different horizontal scenarios for electricity demand and vertical scenarios for coal supply, thereby calculating the coal requirements for different demand scenarios. The results are validated with medium-term coal projections along with the actual coal consumption at power plants for producing electricity.

Missing Linkages in the Electricity–Water Nexus in Indian Agriculture

Agriculture electricity supply has been the Achilles heel in the context of electricity policy and subsidy in India. The study summarises all the electricity consumption methods and numbers in the major agricultural states by state electricity regulatory commissions and researchers. Clear disparities in electricity consumption can be seen for some states and crops in the numbers summarised. It highlights the issues with the current methodologies and proposes to develop better methods for estimation of energy consumption in agriculture.

COVID-19 Economic Stimulus and State-level Performance of Power Distribution Companies

As part of the COVID-19 economic stimulus package, the Government of India increased the borrowing limit of the states from 3% to 5% of the gross state domestic product. The power sector reform at the state level is one of the criteria to avail this extra borrowing. The efficiency parameters of the power sector are analysed here, and it is observed that there are statewise differentials in the financial and operational parameters. The average aggregate technical and commercial losses that should have been 15% by 2018–19, presently, on average, stand at 26.15%. The average cost of supply–average revenue realised has also widened. The operational parameters indicate widening inefficiencies across states in the power infrastructure.

 

Managing Transition to a Low-carbon Electricity Mix in India

Demand for electricity in India is growing due to the increase in GDP and quality of life along with structural changes in the energy sector leading to the increase in the percentage share of electricity in the total final consumption of energy. Decarbonisation of the energy sector is a necessity, and it should be achieved without negatively affecting economic growth of the country. It can be best managed by having a diverse portfolio of technologies as diversity provides supply security, resilience, and hedging against price fluctuations. Therefore, all low-carbon technologies—hydro, nuclear, solar, and wind—should be exploited and provided with a level playing field.

 

Electricity Generation from Bio Pellets

This article discusses the possibilities of using agricultural residues in power generation. It traces the evolution of the use of bio pellets in thermal power plants and the pilot projects implemented by the National Thermal Power Corporation that led to the successful roll-out of the new technology. Finally, it enumerates the advantages and disadvantages of using bio pellets and the emerging challenges.

Enforcing Renewable Purchase Obligations

The Renewable Purchase Obligation mechanism and the trade of Renewable Energy Certificates were introduced to promote investment in renewable energy. However, the RPO requirement has not been met in many cases in India, which has resulted in low trading in RECs. While there are a few instances of state electricity regulatory commissions imposing penalties, a uniform enforcement of this mechanism by imposing specific penalties on non-complying entities can be recommended.

How Over-Invoicing of Imported Coal has Increased Power Tariffs

Forty of India's biggest energy companies are being investigated by a wing of the Union Ministry of Finance for over-invoicing of imported coal. The artificially higher prices of coal have been passed on to electricity consumers across the country. The scam is conservatively estimated by government officials at no less than Rs 29,000 crore, a third of which is in the form of higher power tariffs. Big names from the corporate sector, notably the Adani group and ADAG, are being probed for their alleged involvement in the scandal. An exclusive report.
