  • Power markets in India: their working, advantages, and the road ahead

    Why in the news?

    Amid rising summer demand, the government has permitted the trading of excess electricity produced from “linkage coal” within the nation’s power markets.

    What is the Power Market?

    • A power market is a platform where electricity is bought and sold, enabling generators and consumers to trade electricity based on market-driven prices and conditions.

    Types of Markets related to Power exchanges in India include:

    • Spot Markets: These include real-time markets (RTM) and day-ahead markets (DAM). RTM allows for immediate buying and selling of electricity, while DAM involves bidding for electricity to be delivered the next day.
    • Term-Ahead Markets: These markets facilitate trades for longer durations, ranging from hours to several days in advance, providing more certainty and planning for market participants.

    Their working and Power exchanges in India

    • Market Operation: Power exchanges in India operate as platforms where electricity generators (sellers) and consumers (buyers) participate in trading electricity. Generators submit offers indicating the quantity of electricity they can supply at various prices, while buyers submit bids indicating the quantity they wish to purchase at various prices.
    • Renewable Energy Certificates (REC): Power exchanges also manage the trading of Renewable Energy Certificates (RECs). RECs represent the environmental attributes of renewable electricity generated and can be sold to utilities to meet their renewable purchase obligations (RPOs).
    • Regulation: Power exchanges are regulated by the Central Electricity Regulatory Commission (CERC) in India. The regulatory framework ensures fair and transparent trading practices, oversees market operations and sets rules to promote market integrity.
    • Market Dominance: The Indian Energy Exchange (IEX) is the dominant power exchange in India, handling the majority of electricity trading volume. Other exchanges include Power Exchange India Limited (PXIL) and Hindustan Power Exchange Ltd (HPX), though IEX holds more than 90% of the market share.

    Their advantages 

    • Flexibility: Enables generators to respond swiftly to fluctuating electricity demand by selling surplus power at market-driven prices, enhancing grid stability.
    • Efficiency: Optimizes utilization of coal-based power generation assets, minimizing wastage and maximizing revenue through market-based transactions.
    • Transparency: Promotes transparent pricing mechanisms in the electricity sector, fostering competitive market dynamics and benefiting consumers with potentially lower electricity costs.

    The Road Ahead for Power Exchanges:

    • Market Coupling: It matches bids from different power exchanges to discover a uniform market clearing price, promoting efficiency and reducing price disparities across regions.It enhances price discovery, market stability, and regional grid integration by providing a reliable reference price for policymakers.
    • Capacity Markets: It compensates generators for maintaining available capacity, incentivizing investment in reliable generation infrastructure. They ensure long-term grid reliability, especially during peak demand periods, aligning India’s power market with international standards and attracting investment.
    • International Alignment and Competitiveness: India’s adoption of advanced market structures (like market coupling and capacity markets) aims to align with mature international markets.These developments can foster greater competition, attract investment, and enhance overall sector efficiency and reliability.

  • Create the space for governance with a green heart

    Why in the news?

    As a new term begins for the government and the Lok Sabha, it must prioritize environmental concerns. No government has ever truly prioritized the environment, and the last one, focused on development, actively harmed it.

    Present Himalayan states

    • The Indian Himalayan Region (IHR) encompasses the portion of the Himalayas located within India, extending across thirteen Indian States and Union Territories, including Ladakh, Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, West Bengal, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Assam, and Arunachal Pradesh.

    Problems Associated with Lack of Political Will on Environmental Governance

    • Neglect of Climate Change Mitigation and Adaptation: Inadequate actions to reduce carbon emissions and build climate resilience.And failure to address the remediation aspects of climate change, such as food security and disaster preparedness.
    • Degradation of Forest Cover: Significant decline in both quantitative and qualitative forest cover.Recent legislation weakening forest protections, leading to further environmental damage.
    • Deteriorating Urban Environments: Severe air pollution and water scarcity in major cities, adversely affect public health.Poor sewage treatment infrastructure, resulting in heavily polluted rivers and water bodies.
    • Environmental Degradation in the Himalayas: Rapid glacial melting and altered weather patterns threatening water and food security. Government inaction on local environmental protests and concerns highlights a disconnect between policy and grassroots needs.
    • Ineffective Environmental Impact Assessments (EIA): EIAs are reduced to mere formalities, failing to prevent environmentally harmful projects.Dilution of EIA regulations and lack of meaningful stakeholder engagement, compromising environmental protection efforts.

    How This Can Be Restored?

    • Enhanced Environmental Impact Assessments (EIA): Strengthen EIA mechanisms, elevate them to statutory status, and ensure they are thorough and transparent to prevent projects from causing environmental harm.
    • Restoration Projects: Initiate large-scale conservation and restoration projects for glaciers, forests, and rivers in the Himalayan region.
    • Community Involvement: Actively involve local communities and stakeholders in decision-making processes to ensure their concerns and knowledge are integrated into policy-making.
    • Strict Enforcement of Environmental Laws: Improve enforcement of existing environmental regulations and increase penalties for violations to deter harmful activities.
    • Sustainable Development Policies: Develop and implement policies that balance development with environmental conservation, ensuring long-term ecological health and resilience.
    • Revised Legislation: Reassess and amend legislation like the Forest (Conservation) Amendment Bill, 2023, to provide stronger protections for natural habitats.
    • Resilience Building: Invest in infrastructure and programs aimed at enhancing resilience against climate change impacts, such as improved water management systems and disaster preparedness plans.

    Government steps taken: 

    • The National Mission for Sustaining the Himalayan Ecosystem (NMSHE) was launched as part of India’s National Action Plan on Climate Change to holistically address the vulnerabilities of the Himalayan ecosystem.
    • Under NMSHE, the government has developed a common framework and methodology for climate vulnerability and risk assessment across 12 Himalayan states.
    • The government has also established the “G.B. Pant Institute of Himalayan Environment & Development” to focus on sustainable development and environmental conservation in the Indian Himalayan Region.

    Conclusion: To achieve Sustainable Development Goal 13 (Climate Action), India must enhance environmental governance, prioritize climate resilience, and enforce robust conservation policies to protect the Indian Himalayan Region and its ecosystems.

  • Nuclear Study provides major update on Plutonium Isotope Fission

    Why in the News?

    Recently a study was conducted on Prompt Fission Neutron Spectrum (PFNS) by the US. This study holds significance for design updates in India’s second stage of its nuclear power programme.

    India’s Progress in Nuclear Energy

    On March 4, India advanced to the second stage of its nuclear power programme by beginning the core-loading process of the Prototype Fast Breeder Reactor (PFBR) at the Madras Atomic Power Station in Kalpakkam. 

    India’s 3-stage Nuclear Power Program:

    Description Timeline
    Stage 1 Relies on pressurized heavy water reactors (PHWRs) using natural uranium as fuel. Initiated in the 1950s;

    Operational since the 1960s
    Stage 2 Focuses on developing fast breeder reactors (FBRs) using plutonium-239 produced in Stage 1. Initiated in the 1970s;

    Development phase
    Stage 3 Involves the development of thorium-based reactors utilizing India’s significant thorium reserves. Initiated in the late 1980s/early 1990s;

    Research & Development phase

    What is Prompt Fission Neutron Spectrum (PFNS)?

    • Definition: PFNS refers to neutrons emitted right after a Pu-240 nucleus captures a neutron but before it reaches a stable state.
    • Previous Studies: To date, only one study has investigated PFNS for Pu-240-induced fission at 0.85 mega-electron-volt (MeV). Recently, researchers in the U.S. conducted a second study with neutrons of higher energy than 0.85 MeV.
    • New Findings: The findings reveal significant differences between predicted and measured PFNS, aiding reactor designers and nuclear medicine practitioners.

    About Plutonium-240 and its Fission

    • Neutron Capture: When a Pu-239 nucleus captures a neutron, it can either undergo fission or become Pu-240.
      • Pu-240 is common in nuclear reactors and nuclear weapon test fallout.
    • Pu-240 Behavior: Pu-240 capturing a neutron typically turns into Pu-241.
      • If Pu-240 undergoes fission, there’s uncertainty about the energy of its fission products.
      • Current models use complex calculations to estimate this output.

    Do you know?

    • Plutonium is created from Uranium-238 in nuclear reactors.
    • Plutonium-239 is a weapon-grade fissile material (i.e. used to make nuclear weapons).
      • Pu-239 and Pu-240 are by-products of nuclear reactor operations and nuclear bomb explosions.

    Relevance of PFNS Study to India’s PFBR

    • PFBR Use: The PFBR uses plutonium from CANDU (Canada Deuterium Uranium) reactor spent fuel, which contains Pu-240. Reprocessed PFBR spent fuel will also contain Pu-240.
    • Importance of New Data: New data on Pu-240 behaviour is essential for improving reactor efficiency and safety.

    Production and Characteristics of Pu-240

    • Creation of Pu-239: Pu-239 is created when U-238 is exposed to neutrons in a reactor. As Pu-239 captures neutrons, it turns into Pu-240, which builds up over time.
    • Spontaneous Fission: Pu-240 undergoes spontaneous fission, emitting alpha particles, and is considered a contaminant in weapons-grade plutonium, where its composition is kept below 7%.
    • Reactor-Grade Plutonium: Plutonium with more than 19% Pu-240 is classified as reactor-grade.

    Experimental Findings on PFNS

    • Research at LANSCE: Researchers at Los Alamos Neutron Science Centre (LANSCE) conducted tests by bombarding a pure Pu-240 sample with neutrons of 0.01-800 MeV energy.
    • Detection Setup: The setup included liquid scintillators to detect emitted particles, using a small Pu-240 sample to minimize alpha particle emission.
    • Measurement Focus: They measured the energies of neutrons and other fission products, focusing on neutron-induced fission data.

  • Possible risks of “Acute Poisoning” due to high Capsaicin Levels

    Why in the News?

    Food safety authorities in Denmark have recalled three types of South Korean spicy instant noodles due to potential risks of “acute Capsaicin poisoning.”

    What is Capsaicin?

    • Capsaicin, the chemical responsible for chili pepper spiciness, is primarily found in the white membrane (placenta) of some chili peppers.
    • Mechanism of Capsaicin:
      • Capsaicin binds to TRPV1 receptors in the human body, which detect heat and pain.
      • These receptors are tricked by capsaicin into reacting as if there is a rise in temperature, causing a painful, burning sensation.
      • The body’s response includes sweating, facial redness, runny nose, teary eyes, gut cramps, and diarrhoea as it attempts to cool down and expel the perceived heat.

    Evolutionary Benefits of Capsaicin

    • While birds avoid chilies, rodents consume them.
    • Birds lack TRPV1 receptors, unlike rodents act as seed dispersers, aiding in the germination of chili seeds.
    • Capsaicin serves an evolutionary purpose by deterring mammals from eating the seeds and protecting the plant from fungi and insects.
    • Producing capsaicin is resource-intensive, making spicy chilies more vulnerable to droughts.

    Human Affinity for Spicy Foods

    • Over 3,000 chili cultivars have been bred for varying color, taste, and pungency.
    • Some experts believe humans’ love for spicy foods stems from their antimicrobial benefits, which are particularly useful in hotter climates where food spoils faster.
    • Psychologists argue that eating spicy foods is similar to thrill-seeking activities, providing a simulated risk without actual danger.

    Potential Risks of Capsaicin

    • High concentrations of capsaicin can cause heartburn, gastrointestinal pain, and diarrhoea.
    • Long-term ingestion of high levels may lead to chronic gastrointestinal disorders.
    • Capsaicin poisoning is rare due to the large amount required for toxicity, with a person needing to consume around 2.5 liters of Tabasco sauce to overdose.

  • How long is Carbon is stored in plants?

    Why in the News?

    A recent study in the Science journal indicates that the storage of carbon in terrestrial vegetation is more short-lived and more vulnerable to climate change than previously estimated.

    Carbon Absorption and Storage in Plants

    • Current models may overestimate the time carbon remains stored in plants, meaning it returns to the atmosphere sooner than previously expected.
    • Experts emphasised that while plants and forests play a crucial role in drawing down carbon dioxide, their potential is limited.
    • The study calls for a rapid reduction in fossil fuel emissions to mitigate climate change impacts.

    Key Findings:  

    • Plants and soils absorb 30% of annual carbon dioxide emissions from human activities, mitigating climate change.
    • However, there are gaps in understanding the stability and mechanisms of this carbon storage.

    Use of Radiocarbon (Carbon-14) in Research

    • Researchers used Carbon-14, a radioactive isotope, to track carbon accumulation and turnover in the terrestrial biosphere.
    • Nuclear bomb testing in the 1950s and 1960s increased atmospheric C-14 levels, providing a unique opportunity to study carbon cycling.

    Study Results

    • By analysing C-14 accumulation in plants from 1963 to 1967, researchers compared these findings to current models.
    • The analysis showed that net primary productivity (the rate of new plant tissue creation) is likely at least 80 petagrams of carbon (PgC) per year, higher than the 43-76 PgC per year predicted by current models.
    • The C-14 accumulation in vegetation during 1963-67 was 69 ± 24 ×10²⁶, suggesting a more rapid carbon cycle between the atmosphere and biosphere than previously thought.

    Back2Basics: Carbon-14 and Carbon Dating

    • Carbon dating is a widely used method for determining the age of organic materials that were once living.
    • The method is based on the radioactive decay of Carbon-14 (C-14), an isotope of carbon with an atomic mass of 14.
    • It works by measuring the ratio of C-12 to C-14 in the atmosphere, as well as in plants and animals that acquire carbon through photosynthesis or food consumption.

    The Half-Life Concept

    • Carbon-14 has a half-life of 5,730 ± 40 years—i.e., half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.
    • Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

    Implications of the Study: Reforestation is inadequate

    • Today, reforestation is proposed to remove CO2 from the atmosphere, but trees do not return the CO2 to the geological layers from which the fossil fuels came.
    • This sink is transitory and this study shows us that its duration is even shorter than we thought.
