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?"

Gross Metering : a Cooperative Concept ?

 


Context :

Odisha Electricity Regulatory Commission allows virtual net metering for renewable power consumers 

 (  Indian Express -  12 May 2022 )

 

Extract :

 

With increased demand for group net metering and virtual net metering for use of renewable energy, the Odisha Electricity Regulatory Commission (OERC) has amended its regulations to allow generation of more than 500 KW power from renewable sources.

 

The amended provisions will not only,


#  allow individuals or groups to generate energy from renewable sources -

    solar energy emerging as the most sustainable source –

    

#  but also enable the power producers to export or transfer the surplus to

    the grid and earn credit.

    The process of transferring such energy is known as net metering.

 

Amending its 2016 order, the OERC said the new order will be known as,


   #  net metering

   #  bi-directional metering

   #  gross metering

   #  group net metering

   #  virtual net metering

 

-       and their connectivity with respect to solar photovoltaic projects.

 

Gross metering is a mechanism where,


#  the total energy generated from grid interactive solar photovoltaic system of

    a prosumer and

#  the total energy consumed by the generator

-    are accounted separately through appropriate metering arrangements.

     

 

The total energy consumed by the prosumer is accounted at the applicable

retail tariff and total solar power generated is accounted for at a tariff

determined by the Commission.

 

The prosumer is,


#   a consumer of electricity in the area of supply of the distribution licensee,

#   who uses a self-owned or third party-owned solar power system installed

     on his/her premises,

#   to offset part or all of the electricity requirements and also inject electricity

     into the grid.

 

Under group net metering,


# surplus energy generated from a renewable energy system and exported to

   the grid are regulated in multiple electricity service connections of the same

   user located within the same area of supply.

 

On the other hand, virtual net metering (VNM) is an arrangement in which,


#  the total energy generated from a renewable energy system is exported to

    the grid from the renewable gross meter and the power exported is regulated

    in multiple electricity service connections of engaging customers located in

    the same distribution area of supply.

    

   

 

Ø  Why Gross Metering is problem for Sellers ?  … (  Business Line  /  09 Jan 2022 )


Extract :

India’s rooftop solar capacity is about 6,000 MW, considerably lower than the target of 40,000 MW that the government seeks to achieve by March 2022. To mainly give a fillip to rooftop installations, last month it notified the Electricity (Rights of Consumers) Rules, 2020.


The Rules recognise ‘prosumers’ — a class of consumers who also generate and sell electricity to the grid.


One of the key measures in the Rules is that consumers may put up a solar plant on their premises, rooftop or otherwise, and directly sell the electricity generated to the utility (electricity distribution company or discom). Because few would want to put up a solar plant on their lawns or compounds, these rules largely aim at promoting rooftop solar capacity.


In a system called ‘gross metering’, what prosumers buy from the grid and what is put into the grid are two separate streams.


The minimum capacity of the solar plant for gross metering should be 10 kW, and the upper limit for the capacity would be fixed by what the respective state electricity regulator would permit.

The regulator would also fix the tariff for the sale of electricity from the prosumer.

 

Experts, however, point out that this ‘gross metering’, though well-intended, has one major problem. If you have a rooftop solar plant and wish to sell power to the discom, you have to build the infrastructure needed to evacuate the power. You need to put separate cables all the way from the solar inverter to the gross meter, which has to be installed separately.


“The cost of this additional infrastructure will in most cases be much higher than the cost of the solar PV systems themselves,” says Toine van Megen, Co-Founder, Auroville Consulting, which advises utilities on solar energy. This will be particularly problematic in multi-storey buildings, where the cabling would be longer than that in individual units.


Discoms have never liked rooftop solar plants principally because of two reasons :


One, the plants reduce the demand for power from (typically) well-paying consumers.

Two, the (surplus) electricity supplied to the utility by the rooftop plants is valued at the same price as the consumer pays — even though solar plants produce power at a much cheaper rate.


As such, the discoms have always tried to spook consumer plans to go rooftop, which is the singular reason why rooftop solar hasn’t taken off, despite the government heavily subsidising the installations.


The Ministry of New and Renewable Energy pays 40 per cent of the cost of the plant that is up to 3 kW and 20 per cent for capacities between 3 kW and 10 kW.

But discoms have been imposing their own conditions or holding back approvals to protect their clientèle.


And now comes gross metering.

 

Apparently, the authors of the Rules thought gross metering was simpler and perhaps better paying. But in practice it may not be so simple. After all, nobody puts up a rooftop solar plant aiming to sell power — the idea is for self-consumption; only the surplus is sold. Gross metering tends to look at it as a separate business.

 

Megen says the solution is ‘net feed-in metering’, where in a bidirectional meter electricity flows both ways. Unlike in net metering, there is no net-off, but payment is made separately for what the prosumer sells. This way, you avoid building the evacuation infrastructure.


Experts believe policies should favour prosumers rather than discoms.


Discoms, beware, for battery costs are falling rapidly. With technologies such as solid electrolytes and metal cathodes, energy densities are bound to go up, bringing down storage costs.


Rooftop owners could just buy storage for parking any surplus energy and island themselves goodbye to discoms. For the discoms, there could be no surer way to disaster.

[ E ]      No Godfather for Rooftop Solar ? ……………………[ 01 June 2021 ]

 

Extract :

 

Dear Shri R K Singhji ( Minister for Power ) :

Ø    It is high time we stop limiting our SOLAR VISION HORIZON like a “ Frog

       in the Well “

Ø    It is time to remember that the nomenclature : Roof Top Solar “, somehow

     ties us down to the words ROOF TOP , which is only just one of the

     locations which can be used to harness Solar Energy

      

 Ø   Solar Energy can also be harvested at other locations on Earth, such as

     FARMS , DESERTS, LAKES, MOUNTAIN TOPS, HIGHWAYS , TRAIN TRACKS,

    etc., or even through solar panels farms in  SPACE ( low earth orbits ? ),

     beaming electricity down to Earth-based receivers ( using micro-waves ? )


 Ø  We must break loose  from the narrowly defined, Roof-Top Solar / Land-

      based Solar and latch on to the all-encompassing concept of :

                SOLAR  ENERGY  TRADING INFRASTRUCTURE  ( SETI  )

 


Dear Shri Amitbhai Shah ,



You are the Minister for Cooperatives


Against our target of 40 GW of Rooftop Solar by March 2022, as of today ( mid

May 2022 ), we have managed to achieve, a meagre 6 GW !


To fulfil the commitment made by our PM , Shri Modiji at COP26, there is only ONE

WAY –  Sardar Patel Way !


Please , implement my suggestion to turn this entire system ( of generation–

distribution–sale of Solar Power ) into a :


 CO-OPERATIVE MOVEMENT

 

I urge you to REPLICATE the MIRACLE called AMUL
