Regarding grid connection for plants like 2 MW or so, I think it is indespensible. There can be large variation in power generation and power consumption. Depending on time either can be higher. Hence there is no option but to bank the generated units to grid and utilise from the grid whatever is required.
Just sharing one experience of microhydro project at Bilgaon in Maharashtra. Being a micro hydro project there was very precise control possible on generation side just by controlling the valve and hence the flow. However there was no control on the load side. Finally we decided not to provide switches to the end users, primarily tribals. So when the generation starts all tube lamps will light. Later on we had a controller that had a dump load heaters. Any power produced in excess of load was diverted to the dump load and it will just waste heat, heating air. Infact the generation used to be set slightly above the connected load. In solar PV the system is more complex because even the generation varies with change in radiation, clouds, time etc. Hence grid connection is inevitable.
You forgot to provide link of colorado installation.

Hi Prof. Ajay Chandak
With respect, if the generation is in excess of the village needs, the
excess will be exported to the grid and paid the local FIT. Also if the
local FIT is Gross based, the village will be paid on the gross solar
generation, despite the local consumption.

Dear Friends,
Power produced in any of these plants has to be grid connected. This is for
the reason that at any point of time the quantum of power produced and load
connected from the villagers will not match. Any surplus has to be exported
to the grid and any deficit has to be drawn from the grid. Also there will
be no power produced by solar PV plant in morning and night hours when the
villagers want it.
When we say that power will be supplied to the farmers it only means that
the power produced will be pumped in the grid and power required by the
farmers will be taken from the grid. So if the villagers requirement is a
day is say around 6 MWH of power then it only means that this 6MWH of power
will be generated by this 2 MW solar plant. So these villages are not
dependent on outside world for their power requirement.
You can not avoid grid connection anyway.

Prof. Ajay Chandak.

Dear Mr.Moresh,
2MW Power Plant at Jamuria, West Bengal is yet to complete and 1MW is
fully installed and commissioned.
There is a huge difference between the plant installed in Jamuria and
at Awan. Power generated from the former is not distributed to nearby
villages but fed to grid and used/to be used by a HT consumer from an
industry. In the later case, it seems it will power 4,000 rural homes
for 20,000 people, as per media reports and if it does in reality,
that really a very good news since transmission and distribution
losses can be minimised unlike in other power plants including some of
the large scale wind/solar power plants installed. This issue need to
be stressed or else the most expensive method of generation of solar
power will get wasted. This is where micr-grid concepts have been just
picking up and we should encourage such initiatives.
Also some practical problems are there in solar power plant installed
in Jamuria,W.B related to local people's attitude, land development
issues,payment related issues due to reduction in silicon prices and
also on uploading the power to grid.
Lets meet when you are in India next time as we had,have,to have some
productive interactions.
Last but not least,Mr.Ravisankar's feedback will be taken very +vely
as I do felt reading on full screen may be difficult.
Best Wishes,

Excellent Analysis , Mr. Bhavani. The storage of locally produced energy is the solution for local use of the energy. In such a case the sources of power generation could be solar, wind , hydro or bio. Any locally produced power can be utilized for local use. This also gives tremendous opportunity to small local players. The grid is greedy. This can make 2 brothers jump to throats of each other.

Distributed energy generation and proximity to the point of consumption seems the way to go. In this context how would Geo Thermal energy fare against Solar energy or other sources?
With the availability of energy 24 hours around unlike solar wouldn't this be a better option? Are there any existing Geo Thermal plants in India? What is the uptake rate? What are the comparisons in terms of cost, effectiveness, issues etc?
