    From UPSC perspective, the following things are important:

    Prelims level: Green Term Ahead Market (GTAM)

    Mains level: Not Much

    As a first step towards Greening the Indian short term power market, the  Ministry of Power and New & Renewable Energy (MNRE) has launched pan-India Green Term Ahead Market (GTAM) in electricity.

    About GTAM

    • GTAM is an alternative new model introduced for selling off the power by the renewable developers in the open market without getting into long term PPAs.
    • This would promote RE merchant capacity addition and help in achieving RE capacity addition targets of the country.

    Benefits of GTAM

    • It would lessen the burden on the RE-rich States and incentivize them to develop RE capacity beyond their own RPO.
    • It will benefit buyers of RE through competitive prices and transparent and flexible procurement. It will also benefit RE sellers by providing access to the pan- India market

    Key features

    • Transactions through GTAM will be bilateral in nature with clear identification of corresponding buyers and sellers, there will not be any difficulty in accounting for RPO.
    • GTAM contracts will be segregated into Solar RPO & Non-Solar RPO as RPO targets are also segregated.
    • Further, within the two segments, GTAM contracts will have Green Intraday, Day Ahead Contingency, Daily and Weekly Contracts
    • Green Intraday Contract & Day Ahead Contingency Contract – Bidding will take place on a 15-minute time-block wise MW basis.
    • Daily & Weekly Contracts – Bidding will take place on an MWh basis.
    • Price discovery will take place on a continuous basis i.e. price-time priority basis. Subsequently, looking at the market conditions open auction can be introduced for daily & weekly contracts.
    • Energy scheduled through GTAM contract shall be considered as deemed RPO compliance of the buyer.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Special Frontier Force (SFF)

    Mains level: India's security forces

    There have been reports that a Special Frontier Force (SFF) unit, referred to as Vikas Battalion, has been instrumental in occupying some key heights on the LAC.

    Try this question for mains:

    Q.“It cannot be business as usual with China after the border clash.” Critically comment.

    What is the Special Frontier Force (SFF)?

    • SFF was raised in the immediate aftermath of the 1962 Sino-India war.
    • It was a covert outfit which recruited Tibetans (now it has a mixture of Tibetans and Gorkhas) and initially went by the name of Establishment 22.
    • It was named so because it was raised by Major General Sujan Singh Uban, an Artillery officer who had commanded 22 Mountain Regiment.
    • He, therefore, named the new covert group after his regiment. Subsequently, the group was renamed as Special Frontier Force.
    • SFF now falls under the purview of the Cabinet Secretariat where it is headed by an Inspector General who is an Army officer of the rank of Major General.

    Is SFF a part of the Army?

    • Strictly speaking, the SFF units are not part of the Army but they function under the operational control of the Army.
    • The units have their own rank structures which have equivalent status with Army ranks.
    • However, they are highly trained Special Forces personnel who can undertake a variety of tasks which would normally be performed by any Special Forces unit.
    • The SFF units, therefore, function virtually as any other Army unit in operational areas despite having a separate charter and history.

    Major operations conducted

    • There are several overt and covert operations in which SFF units have taken part over the years.
    • They took part in operations in the 1971 war, Operation Blue Star in Golden Temple Amritsar, Kargil conflict and in counter-insurgency operations in the country.
    • There are several other operations too in which the SFF has participated but the details are classified.

    What is Carbon-14 (C14) Battery?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: C-14, Carbon Dating

    Mains level: Scientific management of nuclear waste and its disposal

    A California-based company has made a self-charging battery, which can run for 28,000 years on a single charge, by trapping carbon-14 (C14) nuclear waste in artificial diamond-case.

    Try this PYQ:

    Q.The known forces of nature can be divided into four classes, viz. gravity, electromagnetism, weak nuclear force and strong nuclear force. With reference to them, which one of the following statements is not correct?

    (a) Gravity is the strongest of the four

    (b) Electromagnetism act only on particles with an electric charge

    (c) Weak nuclear force causes radioactivity

    (d) Strong nuclear force holds protons and neutrons inside the nuclear of an atom.

    What is C14?

    • Carbon-14 (14C), or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
    • There are three naturally occurring isotopes of carbon on Earth: carbon-12, which makes up 99% of all carbon on Earth; carbon-13, which makes up 1%; and carbon-14, which occurs in trace amounts.
    • Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.

    C14 battery

    • The battery works by generating electricity on its own from a shower of electrons as a result of radioactive decay scattered and deposited in the artificial diamond-case.
    • The battery can be used in electric vehicles, mobile phones, laptops, tablets, drones, watches, cameras, health monitors and even sensors.
    • It is also said to be extremely safe and tamper-proof as it is coated with a non-radioactive diamond which prevents radiation leaks.

    Best example of nuke waste recycling

    • It is estimated that 33 million cubic metres of global nuclear waste will cost over $100 billion to manage and dispose of.
    • And a lot of this waste is graphite that is one of the higher risks of radioactive waste and one of the most expensive and problematic waste to store.

    Its applications

    • The company says its battery can be used to powerhouses, and that any excess electricity generated can be sold to the grid.
    • As the new battery need not be replaced, it can be installed in hard to reach places like pacemakers and implants, where a regular change of battery is not possible.
    • Another area of use is space electronics. The battery is said to power space equipment in rockets.
    • It can power the electrical needs of space crafts, like providing power to cockpits and assisting launch into the upper atmosphere.
