SCENARIO

n a s e wor s s x arges energy mar e an s per

capita consumption is expected to increase from 606 Kilo, .

Indias total power generation capacity on July 31, 2006

was 126,838 MW.

s, coa ase un s genera e , ;

hydropower generated 32,975 MW; gas based stations

6,193 MW; nuclear power generated 3,900 MW and

diesel generator generated 1,201 MW.

India is in the solar belt of the world. High incidence of solar radiation,

geographic latitude, and demand pattern of energy provide appropriate

conditions for utilization of solar energy in the country.

the

Prime

Minister

of

India,

Dr.Manmohan Singhstated:

Our vision is to make Indias economic development energy

efficient. Over a period of time, we must pioneer a graduated shiftrom econom c act v ty ase on oss ue s to one ase on non

fossil fuels and from reliance on nonrenewable and depleting

sources o ener to renewable sources o ener . In this strate

the sun occupies centrestage, as it should, being literally the

original source of all energy. We will pool our scientific, technical

an manager a a en s, w su c en nanc a resources, o

develop solar energy as a source of abundant energy to power our

economy and to transform the lives of our people. Our success inthis endeavour will change the face of India. It would also enable

India to help change the destinies of people around the world.

in promotion of solar energy technologies.

The Mission aims to achieve volume production, rapid

diffusion and deployment of solar technologies across thecoun ry a a sca e w c ea s o cos re uc on an a m ngto achieve grid parity by 2022.

PANIITPROJECT

The Department of Science & Technology is supporting a project on SolarThermal Power generation, with participation from all IITs and the National

erma ower orporat on. s a part o t s pro ect, a storage ntegratethermal power plant (average power for 8 hours/day) will be setup.

This is based on direct steam generation using Fresnel and linear parabolic mirror.pressure, high temperature steam will be carried out, in steam accumulators.This will be supplemented by sensible storage in the supporting blocks ofcollector tubes. To a smaller extent, storage in a cascade of molten salt andphasechange materials will also be attempted.

For the generation of high temperature steam, inverted cavity type solarcollectors with evacuated tubes will be employed. Special coatings will beemp oye or ncreas ng so ar energy a sorpt on or to prevent eat osses.

A fully instrumented research facility will help in the monitoring of the plantperformance.

food for around 1000 people. The

Thermic fluid is used to transfer the

energy collected by the receiver and the

CURRENT SITUATION

A few demonstration projects on solar air conditioning are on in thecountry under the existing scheme of MNRE on solar steam generating

systems:

A 350 kW solar air conditioning system using Scheffler dishes is underinstallation at Muni Seva Ashram, near Vadodara with part support from MNRE.

being used.

A 300 kW TR solar air conditioning plant using Scheffler dishes has been

installed at TVS Suzuki factory near Chennai and is under testing.

ACTION PLAN TO FILL GAPS

Improvements in Scheffler technology to reduce its manual operations,optimize it performance and lower the cost.

Development of new designs of fully automatically tracked solarconcentrators

Development of smaller VAR machines (both wet and dry sorption) incapacity range of 1 to 15 TR with the involvement of Indian industr ies and

research institutions.

Optimum designing & integration of various components of solar airconditioning systems using available knowledge base.

Standardization of various components of existing technologies on solar
