2.  What is TEDA?
- TEDA is Tamil Nadu Energy Development
Agency.
- It is an independent agency setup by
Government of Tamil Nadu in the year 1984
-to create awareness and migrate the State from
using fossil fuels to renewable energy.

3. Decentralized systems:
· 25068 Solar domestic lighting systems installed in Tamil Nadu with
assistance from Government.
· 6095 Solar street lights installed in pubic places/streets mostly in village
panchayats with Government assistance and active support and involvement of
Rural Development Department.
· Solar water and air heating/drying systems installed for a collector area of
28791 sq.m.
· Biomass gasifiers with cumulative capacity of 5444 KW are in operation.
· 189 nos. of community and toilet linked biogas plants have been constructed
in the State under subsidy scheme

4. CM’S SOLAR POWERED GREEN
HOUSE SCHEME

5.  Under this scheme 3 lakh houses will be
constructed with solar powered lighting systems
over a period of 5 years from 2011-12 to 2015-16
for the benefit of poor in rural areas.
 The solar lighting system consists of 5 nos CFLs/
LEDs one each in Living room, Bed room,
Kitchen, Toilet & Verandah.
 These CFLs/ LEDs can be operated for 5 hrs a day.

6.  The solar home lighting system is with grid backup and has following
innovative features:
1. Smart power conditioning unit to charge the battery from grid only in rainy
or cloudy days when solar power is insufficient.
2. MNRE design of solar system is with 3 day autonomy. ie., even if it is
raining for 3 days the system will work as the required energy for 3 days is
generated by the panel & stored in the battery. Provision of grid back up
avoids requirement of autonomy for more than a day. Hence additional
capacity of battery and SPV panel required for more autonomy is reduced,
resulting in huge capital saving.
3. Direct EB supply to lights in case of failure of Battery/Inverter
4. Comprehensive maintenance of the systems by the supplier for 5 years
5. Call Centre is established for addressing the grievance of beneficiaries.

7. ENERGISATION OF STREET LIGHTS
THROUGH SOLAR POWER

8.  Govt of Tamil Nadu has decided to energize 1 lakh street lights in village
panchayats through solar power over a period of 5 years up to 2016.
 The street lights are energized through solar power in three categories.
1. Per year 18000 existing street lights with 40W incandescent bulbs or tube
lights are replaced with 20W LED lights and powered in clusters from
centralized Solar Photo Voltaic(SPV) power plants through the existing
distribution line of TANGEDCO, with grid backup.
2. per year 1000 new LED based street lights are powered in clusters from
centralized SPV power plants.
3. Per year 1000new LED based stand alone street lights are powered by SPV.

9.  The solar street lighting system has following innovative features:
1. Remote monitoring unit is provided to monitor the performance of
the street lighting systems from anywhere. A daily fault report will be
generated & given to the installer for rectification within 48 Hrs.
Tampering of Panel, battery & inverter housing is also monitored.
2. Automatic ON/OFF control of the lights from 6am to 6 pm
3. Automatic dimming of lights to one third during off peak hours. The
LED lights glow with full brightness during the peak hours (Evening
6.00pm-10.00pm & Morning 5.00am – 6.00am) and one third of full
brightness during remaining period.
4.This reduces the capacity of SPV panel, Battery and other accessories
resulting in huge reduction in investment, while going for large scale
implementation.
