Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

The Surge of Solar

 


 

Context :

Adani, JSW, ReNew Power line up fresh investments for renewables in Rajasthan   /   BL / 02 April


HIGHLIGHTS


Solar Projects applied for :


Ø  Adani Group………………… 11,700  MW………………..Rs  46,000  crore

Ø  JSW Group…………………… 10,000  MW………………. Rs  48,500  crore

Ø  ReNew Power………………. 10,000  MW……………….Rs  30,000  crore

Ø  Greenko…………………………. 4,500  MW……………….Rs  30,000  crore

--------------------------------------------------------------------------------------------

               Total……………………………..36,200  MW……………….. Rs 154,500  crore

--------------------------------------------------------------------------------------------

“If every potential project comes on ground, Rajasthan will see total 70,729 MW of renewable projects attracting investments worth over ₹2.75-lakh crore. “


Giving an outline about new solar parks coming up in Rajasthan, Agarwal informed that three such solar parks are being set up with capacity of 3,175 MW spread across 7,232 hectares. The parks are being developed in PPP mode jointly with Government of Rajasthan and private players including Essel Infra and Adani Group.


Rajasthan bets big on its natural advantage with highest solar radiation at 5.72 kWh/sq meter per day and 325 sunny days providing solar power potential of 142 Gw, which is about 19 per cent of 748 GW for India. The state is also looking to capitalise the open inter-state transmission scheme till 2023, which will encourage developers to set up plants in Rajasthan to supply power in other States.


In near term, Rajasthan eyes 30,000 MW of renewable energy generation by 2024-25, which Agarwal is confident to achieve before time.

MY TAKE


[ A ]   Technology

Ø  Biggest problem with Solar Power is that of being able to “ Store “ that energy when Sun is not shining. Energy produced during the sunlight hours of daytime must be stored in very large GRID SIZE storage batteries, which can be withdrawn / consumed during the “ late evening – early morning – night time “

Ø  We have to find a Battery Technology which can store / charge / discharge , GWh of energy , day after day / year after year, without much degradation

Ø  Currently available Lithium-ion Batteries are unsuitable for such heavy duty , without heating up and catching fire

Ø  Fortunately,  such a technology is already available commercially

Ø  This technology developed by Prof Sadoway   ( dsadoway@mit.edu )   is being offered by a US based company AMBRI 

Ø  This liquid metal batteries are claimed to be 30 – 50 % cheaper than Li-ion batteries on  $/Kwh “basis


[ B ]   Cost of imported  Solar Panels

Ø  Recently, there was an announcement by the Central Government to raise the IMPORT DUTY for solar panels to 40 % ( from current Safeguard duty  of 15 % ) from April 2022.


      Idea is to protect the domestic Solar Panel manufacturers and make their

      supplies price-competitive with  imported panels, mostly from China

      

This is very short-sighted decision


If anything, with immediate effect, we should reduce the import duty to ZERO till 2030


We must not let our goal of reaching 475 GW of Solar by 2030, suffer in order to encourage / protect, a local industry ( Due to huge demand, there is no danger of any employees losing jobs )


By reducing import duty to ZERO till 2030, we should target to reach 600 GW – thereby offering power at Re ONE / Kwh , which will generate MILLIONS of NEW JOBS

 

Dear Shri R K Singhji,


Over the past few days, there have been unconfirmed reports that the Central Government will offer $ 1 Billion ( approx. Rs 7300 crore ) to any CHIP maker who puts up a semi-conductor manufacturing plant in India


This is along the lines of PLI ( Production Linked Incentive ) scheme introduced for several industries


No doubt, this will help the manufacturers – provided there is a MARKET DEMAND for their INCREASED PRODUCTION ( over some base-line )


However, one of the factors that foreign industries consider for setting up manufacturing facilities in India, is the cost of ELECTRICITY – especially in industries which are HIGHLY AUTOMATED ( like CHIP manufacture ) and, use THOUSANDS of POWER GUZZLING robots but very few humans .


They have a very low MANPOWER COST but a very high ELECTRIC POWER COST


Following data tell us about the COST of ELECTRIC POWER ( Cents / Kwh ) for Industrial Consumers in some countries where there are major manufacturers of Semi-Conductor CHIPS :


Ø  Japan…………………………….. 15.00

Ø  Taiwan………………………….. 13.40

Ø   S Korea…………………………..10.50

Ø  China……………………………… 10.20

Ø  USA………………………………….  6.83


Compared to these, Industrial Consumers in Mumbai pay  12.00 cents ( Rs 9.0 ) per Kwh


Imagine the impact on our entire ECONOMY ( - and consequent JOB GENERATION ), if we can generate and sell electric power for :

0.14 Cents / Kwh ( Re  ONE per Kwh )  !


I urge you to consider my suggestion

Extract from this E Mail :


Ø  These deserts have , between them , the potential to generate 315.7 GW of Solar plus Wind power, compared with our present installed capacity of 331 GW

 

 

·                But, how to “ Store “ all that huge amount of Solar generated

                 electricity and use it round the clock when Sun is not shining ?

 

                      

              This ( storage of solar generated power ) was not possible till yesterday

 

              But it just became possible !

 

               Only yesterday , Elon Musk ( TESLA ) completed installation of a 100

               MW / 129 MWh , Lithium-ion Battery Storage facility in Australia, for a

               cost of $ 50 million

               All within 100 days, ensuring no more  black outs  in South Australia  !

 

              To store that 316 GW ( 316,000 MW ) of solar power generated in our

              deserts , we will need 3160 Storage Batteries of the size ( 100 MW )

              installed in Australia

              

 

             That would cost , $ 158 Billion ( Rs 11.15 lakh*crore )

 

              In all , we need to raise :

 

 

                  Ø  For 316 GW solar power projects in our deserts…………$  316  Billion

 

                  Ø  For 3160 Mega Storage Batteries………………………………..$  158  Billion

 

              Total of …………………………………………………………………………… $  474  Billion
