Climate Change and Renewable EnergyThe impact of global warming and res ultant clim ate change is posing a

grave env ironment al threat to all life on the planet. Therefore, it is our

prime res pons ib ility to safeguard our p lanet whi le meeting our ener gy

needs.

In this scenario, a business- as-us ual appr oac h is no longer a viable

option; it is time to max imis e the us e of renewable energy, whic h alone

is sustainable in the long run.

Greater relianc e on renewable energy sources offer enormous

economic, socia l, and envir onm ental benefits and provide ener gy

security to the nat ion9

SOLAR INSOLATION MAP OF INDIA

India is located in the equatorial sun belt of the earth, thereby receiving abundant radiant energy from the sun.

The daily average solar energy incident over India varies from 4 to 7 kWhr/m2 with clear sunny weather experienced for 250 – 300 days a year depending upon location.

Rajasthan, Gujarat and TamilNadu have the best solar insolation level in the country .

GRID CONNE CTED SOLAR POWER GENERATION

Grid connected Solar PhotoVoltaics (SPV):

Light energy derived from sun is directly converted to electrical energy through PV Cells (Silicon Cells), eliminating the need for batteries.

Grid connected, Concentrated Solar thermal Power generation (CSP):

Heat energy derived from the sun is converted to electrical energy

through the conventional steam turbine cycle.

TYPES OF SOLAR PHOTOVOLTAIC CELLS

1. Monocrystalline Silicon - 24% efficiency

2. Poly / MulticrystallineSilicon - 18% efficiencyAround 85 % of the existing PV systems in the world areof this type.

3. Thin film technology .

Amorphous silicon - 11-12% efficiencyCadmium Telluride - 17% efficiency

Copper Indium Gallium Diselenide (CIGD) - 20% efficiency

Thin film technology, emerging technology is cost effective and gaining acceptance in the Global PV market, contributing to 15% of installed capacity. In due course, thin film technology would super cede mono/Poly crystalline.

CONCENTRATED SOLAR P OWER BASED

SOLAR THERMAL SYSTEMS

The solar power tower plant comprises of

an array of heliostats (mirro rs) which concentrates the sun's rays to the top of the high tower where the solar receiver is located. The receiver collects the concentrated sun radiation and transfers the energy to generate steam. The steam drives the turbo generator thereby producing electricity. Temperatures upto1000 deg C can be achieved through power tower systems.

POWER TOWER

POWER TOWER-S CHE MATIC DIA GRA M

This 11MW ABENGOA’s solar central tower plant in SOLNOVA (SEVILLE, SPAIN) was visited by the CMD and GM, TEDA .

The cost of the 11 MW solar central tower plant in Spain is 40 million euros, i.e. around Rs. 248 crores. The plant generates 24.3 million units per year of clean energy.

PARABOLIC TROUGH SOLAR SYSTEMS

Trough solar systems use parabolic curved/ trough shaped reflectors that focus the sun's energy onto a receiver pipe running at the focus of the reflector. The concentrated energy heats a heat transfer fluid (HTF), usually oil, flowing through the pipe. This fluid is then used to generate steam which powers a turbine that drives an electric generator.

THERMAL S TORAGE SYS TE MS I N SOLAR THE RMAL POWER P LANTS

A major advantage in Solar thermal Plant compared to SPV/other renewable

energy is the thermal storage system, i.e., before using the heat to generate steam, a part of the heat can be stored for later use/ during peak hours.

Storing heat energy is cheaper than storing energy in any other form. By building a sufficiently large heat storage system, it is possible to generate power even when the sun is not shining.

Thermal Energy storage systems can extend the operational time of Solar thermal power plants by 6-12 hours.

ADVANTAGES OF CONCENTRATED SOLAR POWER TECHNOLOGY

ØCSP technology is s imple, versatile and commercially proven.

ØNo specific land constraints & various technologies are available to suit the land requirements.

ØEnergy storage facility .

ØImproved effic iency with reduced cost of generation.

ØMore technological developments can be expected resulting in increased power generating capacity.

ØBest suited for high capacity plants, can be scaled up to several hundred megawatts, putting it in the same utility-scale c lass as coal and nuclear.

ØIn contrast to wind power, the heat transfer medium deployed in this technology does allow power fluctuations due to transient c louds, which is the case with wind energy generating systems making it an infirm power.

BAGASSE BASED CO-GENERATION PLANTS IN SUGAR MILLS

Ø Tamil Nadu is No.1 State in the country in Co-gener ation of power

from sugar mi lls.

Ø 3 Nos. Co-operat ive and 18 Nos. pr ivate s ugar mil ls have instal led

cogenerat ion p lants in the state.

Ø The total installed capacity under cogeneration is 446.10 MW.

This is 30% of the installed capacity in the entire country with the

exportable surplus of 256.11 MW as on 31.3.2008.

CO-GENE RATI ON P LANTS IN SUGAR MILLSOF TAMI L NADU

Ø The sugar mil ls use bagasse as fuel during crus hing seas on and

coal / other biomass during non-crus hing seas on. A sugar mil l of

2500 TCD can produce 15 MW power.

Ø Sugar mi lls with c ogener ation use the entire bagasse and produc e

surplus power which after meeting own consumption is exported to

grid, earn ing higher incom e. This improves the profitabil ity of sugar

mills.

TARIFF• The purchas e pr ice ( dur ing crushing season) for the Co- generated

Power has been fixed as Rs.4.50 / unit by the state Regulatory

commission (TNE RC).

• The crush ing season of the sugar m ills norm ally starts from the 1st of

Decem ber and ends by 30t h June of the succeeding year. The non-

crushing season is from July to November dur ing whic h any type of

fuel may be used in the Boiler including bagasse.

• If the PLF achieved in any financ ial year is m ore than 55% , then the

rate for the excess energy pr oduced over and abov e 55% shall be

equivalent to the rate fixed for the Fossil Fuel based Co-generation

Plant.

CO GENERATI ON PLANTS I N CO-OPERATIVE SUGAR MI LLS

• TAMIL NADU ELECTRICITY BOARD (TNEB) has taken the initiative to set

up Co-generation power plants in the Co-operative sugar mills of Tamil

Nadu.

• TNEB has also signed an MoU with Power Finance Corporation for availing

loan to a tune of Rs.1200 Crores for funding these projects.

• DPR has been finalised for setting up the Co-generation plants for a total

capacity of 183 MW in 12 Co-operative sugar mills (120 MW to be exported

to Grid).

CAPTIVE BIOGAS PLANT IN TRICHY DISTILLERIES AND CHEMICALS LTD, TAMIL NADU

• Trichy Distilleries and Chemicals (TDC), is involved in manufacture of

industrial alcohol and alcohol-based chemicals.

• The Company, holding ISO: 9001 certificate, is having the Distillery unit at

Senthannipuram, Tiruchirapalli, Tamil Nadu. The Bio gas generated from

the anaerobic digestion systems, was previously used for low pressure

boiler towards process heating applications.

• Due to acute shortage of power, the Company was also generating 40% of

their power requirement through DG sets at an average cost of power

around Rs.6.50 per unit.

CAP TIVE BI OGAS PLANT I N TRICHY DIS TI LLERIES AND CHE MICALS LTD.

• The Company has now installed a 1.415 MW Biogas based power plant using

biogas generated from distillery effluents using Gas engines, with assistance

of MNRE.

• The Plant is capable of producing 60 KLPD of alcohol from molasses and the

distillery effluents are treated in 2 Nos. anaerobic digestors generating around

25000 m3 of bio gas / day.

• Out of the total biogas generated, 17000 m3 / day is used for power

generation and the balance is used for Boiler applications.
