TAMIL NADU ENERGY DEVELOP MENT AGE NCY
v The Tamil Nadu Ener gy Developm ent Agency (TEDA) is a Nodal
Agency of the Ministry of New and Renewable Energy (MNRE),
Govt. of India for the promotion of Renewable Energy schemes in
the State.
v It is under the adm in istrative c ontro l of Ener gy Departm ent,
Government of Tamil Nadu.
Ø Identification and potential estimation of renewable energy in the State.
Ø Create awareness on the potential and prospects for use of renewable energy.
Ø Enhance renewable energy contribution in the overall energy mix in the State grid.
Ø Abatement of green house gas emissions by promoting the use of renewable energy for grid power generation and as stand alone systems to combat global warming.
Ø Development and implementation of sustainable energy security policy towards attaining energy independence in small villages.
OBJECTIVES OF TEDAENERGY
• Energy has become essential commodity to modern society.
• Development of a country is highly correlated to per capita energy consumption.
• Increasing population, modern civilization and technological advances
contribute to increased consumption of energy.
• Most of our energy demands are met by burning fossil fuels, which is
accelerating global warming resulting to Increasing sea levels, Floods,
Earthquakes, Droughts, etc.

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.

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.

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

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.
