My #thread on Rs.2000 notes.

Total number of Rs. 2000 notes was reduced from
33,632 lakhs on 31/03/2018 to
21,420 lakhs on 31/03/2022,
ie,36.3% reduction in 5 years!

But value-wise, it is drastically reduced from
50.2% of total value in 2017 to
13.8% of same in 2022 Image To replace the quantity of Rs.2000 notes with Rs.500 notes, RBI only needs to print 85,860 lakh pieces Rs.500 notes.

In 2021-22, RBI printed 1,28,003 lakh pieces of Rs.500 currency.

RBI has the capacity to print & supply around 2,22,500 lakh notes every year..

Backdoor ambush: Adani attempts to acquire significant stake in NDTV @sritara
frontline.thehindu.com/the-nation/bac… For millennia, peasants have lost their land to rapacious landlords who leveraged loans extended to them in times of distress. Ironically, this time-tested scheme of asset acquisition works just as well with a modern enterprise, as NDTV, the pioneering private Indian broadcaster.

All big 8 dams in Kerala opened & spilled - a rare event after 2018!

Idukki, Idamalayar, Kakki & Banasurasagar of KSEBL

Malampuzha & Kallada of Irrigation Department

Mullaperiyar & Parambikulam operated by TN

Arm chair pundits propagating that dams create floods hiding These 8 out of 39 reservoirs hold 78% of the total storage inside Kerala.

We had sleepless nights for more than a week. Our administrators listened to scientific inputs and data - trusted our inputs all along.

We assured safe releases in the most challenging circumstances

Idukki reservoir, Kerala's biggest, is on RED Alert!

But nothing to worry, when to open it will be decided soon after State Rule Level Committee today noon.

There will be only moderate releases with present situation as we have plenty of dynamic cushion

#KeralaFloods2022 We regulated Idukki since July 20 to keep it at check looking at various global forecasts for 14 days, not blindly following IMD.

The professional reservoir management of KSEBL resulted to save Kochi from flooding last week, as Idukki absorbed all very heavy flows

Reasons for coal shortage is mainly due to 3 reasons.

1. Huge Arrear outstanding against GENCOs
2. Single Window e-auction for non-linked domestic coal
3. Huge price of coal at international market due to Ukraine war As per official PRAAPTI portal, the undisputed dues outstanding against GENCOS from the DISCOMS as of April 2022 had touched 1.068 lakh crores.

Many DISCOMS arrear is outstanding from 6 months to more than 12 months.

So cash flow to GENCOS throttled

Today's @the_hindu says concern on the #Mullaperiyar Dam was first raised in 1979.

As our research & memory is so short, let me share @timesofindia Mumbai Edition dated 11.05.1962 (a typed copy from Kerala Secretariat files) Interestingly, who raised alarm about safety of Mullaperiyar Dam after independence?

Not Kerala Engineers, it is TN PWD Engineers who said that the dam is seismically & hydrologically NOT SAFE and recommended strengthening!

They even published papers in reputed journals!

"If the rule curve acknowledges 142 feet, here it is equal to permitted Full Reservoir Level (FRL) at the end of the season.

But if you blindly follow it, you will be forced to throw all the water downstream in case it rains." So prudence is required when there is cyclonic circulation prevailing and heavy rainfall alerts are around.

One should never store upto FRL.

I had to fight to sell this important point on operational safery to many of peers too!

If someone is accusing High prices of Fuel is due to MMS Government's opening Petroleum sector to open market, they are shutting their eyes & propagating inconvenient truths.

A #thread on what lead to such a decision Due to volatility of the markets, the very subsidies provided by the Government of keeping the fuel prices to check became unsustainable!

actual under-recovery in 2012-13 was ₹ 1,61,029 crore, out of which Diesel alone accounted for ₹ 92,061 crores (57%).

What ails India’s coronavirus genome sequencing system

The country sequenced only 0.2% samples till date, one of the lowest in the world

Evidence based policy? How dare you? downtoearth.org.in/news/governanc… To date, Maharashtra (14,003 samples) and Kerala (5,485 samples) have sequenced and analysed 23 % and 9 % of the country’s total volume analysed. 

Do these % makes any sense? Be worried

UK total population (6.82 crores ) is almost double of Kerala's (3.47 crores).

UK fully vaccinated around 60.38 % of its total population & partially vaccinated 9.46%.

Meanwhile Kerala fully vaccinated only 19.6% of its total population & partially vaccinated 33.5%. #Thread Unlike UK, Kerala is not sovereign & cannot give indemnity bond or export vaccines.

Kerala is at at the mercy of the Union Govt to get its vaccines.

If supply is ensured, Kerala would have long back vaccinated its whole adult population, we have the wherewithal to do it.

But #Kerala's #COVID19 cases showing a downward trend, though it is not so significant ...

See the 7 day moving average daily infections graph.

How we will behave in coming days will define our #COVID19 trajectory.

Please be responsible to you and your society! Not sure what we are now witnessing is the 3rd wave or 2nd wave, maybe it is like 2 monsoon overlap each other here.

If Kerala can fully vaccinate its population, then we can negotiate next wave.

Kerala has the wherewithal to fast vaccinate, if it is made available!

India so far fully vaccinated only 9.7% & partially vaccinated 22.7% of its total population.

If we are taking our 94 crores 18 plus adult population, the above figures will be 13.3% and 33.1% respectively.

Statewise progress can be easily comprehended from this map. Image The States who have fully vaccinated more than 20% of their population are given in GREEN.

While the worst performing States with less than 5% fully vaccinated are given in PINK

Kerala fully vaccinated 19.4% & partially vaccinated 32.1% of its total population.

At least 51.6% of its total population got a single jab.

77% of its population is 18 plus, which means Kerala has given a single jab to 67% of its eligible population.

Districtwise map is here Image Kerala is having a tremendous job at both Malappuram & Palakkad Districts which are lagging on vaccination.

While Pathanamthitta & Wayanad are performing extremely well in vaccination

This is the new spin...

Please go through archives and what Late Jaitely told when he first increased the excise duty in Modi 1 Government.

Also new agricultural cess is for paying off interests of oil bonds?

Please do some basic journalism .. Understand that Government introduced/increased cess for denying State's eligible share.

Look at how ₹32.90 divided


Road & infrastructure cess - ₹18/lit
Agri infra/development cess - ₹2.50/lit


Special Addl Excise Duty - ₹11/lit

Basic Excise - ₹1.40/l
