If you don’t obsolete yourself…
Then someone else will
( Ted Levitt in his essay , “ Marketing Myopia )
Apparently, Mumbai DISCOMS ( Adani – Tata – BEST ) seems to have realized this
Context :
Mumbai: Firms woo residents to solar panels with subsidy, bill savings / TOI / 24 Aug 2021
Extract :
Ø DISCOMs announced up to 40 % subsidy on installing solar panels on building rooftops
Ø There will be a net metering system, wherein whatever solar power you generate, goes to the grid.And this is adjusted with
your monthly electricity bill
Ø Excess units generated will be credited in future billings
Ø A 1 kWp panel – it occupies 110 sq ft – costs Rs 46,000, but with 40 % subsidy it reduces to Rs 27,600 , including tax,
installation, 5-year maintenance
Ø The savings could range from Rs 800 to Rs 2400 a month, depending on 1 – 3 kWp of solar panel installed
Ø On the other hand, if the panel generates more units than what you consume, then the EXCESS units are kept in an
ENERGY BANK
Ø One can install a maximum 10 kWp panels on a rooftop
MY TAKE :
Ø Most of these proviso are old stuff . May be earlier subsidy of 30 % got raised to 40 % ( tinkering ? )
Ø What did enthuse me however, is the use of the term “ ENERGY BANK “ – something which I suggested in my following
earlier e-mails :
# Congratulations , Shri R K Singhji ……………… 19 Nov 2020
# Congratulations, Shri Vijaybhai Rupaniji ………. 30 Dec 2020
# Congratulations , Shri Saurabh Patelji …………….31 Dec 2020
Ø Now this new term ( ENERGY BANK ), implies ( as in our normal financial banks ), the introduction of the concept of “ Safe
Keeping / Storing “ of your surplus Solar generated units ( instead of cash )
Ø At present, DISCOMS just “ Buy and Sell “ power. They do not have Grid-scale STORAGE BATTERIES
Ø They simply ask the power generating plants ( mostly coal based ) to step up or step down the generation, depending upon
the demand at the moment
Ø Generating plants themselves do not have grid-scale storage batteries ( 100 MW + )
Ø Hence, all power remaining UN-CONSUMED at any given moment, is lost for ever !
Ø Now, if DISCOMS promise to STORE your excess units, then they must create STORAGE capacities, in the form of Storage
Batteries ( several, distributed geographically in areas they serve ). May be, the DISCOMS will be forced to join hands and
create COMMON battery facilities. They will keep track of units “ deposited “ and units “ withdrawn “ by each DISCOM – and
by each customer of each DISCOM
Ø That is inevitable since all existing coal-based plants are bound to gradually shut down over the next 10 years
Ø If 100,000 ( 1 lakh ) rooftop each generate 10kWp each, that is 1,000 MW ( 1 GW )
Ø Now, Govt had set a target of 40 GW of Rooftop Solar by 2022 ( far from reaching that )
Ø But whenever we do, that would amount to 40 Lakh rooftop installations of 10kWp each
Ø But most rooftops can manage only 5 kWp (550 sq ft of terrace space )
Ø That would mean, we need 80 Lakh rooftop installations ( 8 million )
Ø India had approx. 32 MILLION buildings ( Stone + Concrete ) as per 2001 Census
Ø If, someday all of these buildings were to have Solar rooftop installations, what could be the “ Nature of Business “ for the
DISCOMS ?
Ø They would, no more be in the business of, “ Buying and Selling “ power ( whether generated by Solar Farms or rooftops )
Ø May be they will “ charge “ their customers for “ Safe-keeping / Storing “ excess units ( some foreign banks do NOT pay
you any interest for your money lying with them – instead they “ charge “ you a small FEE for safe-keeping )
Ø I suspect Adani – TATA – BEST officers got to read my following blog :
