TAMIL NADU HAS A HUGE POTENTIAL FOR SOLAR ENERGY

• India lies in the sunny region of the world. • India receives 4 to 7 KWhr of solar radiation per sqm per day. • India has 250-300 sunny days in a year depending on location. Tamil Nadu has reasonably high solar insolation (5.6 – 6.0 kWh/sq. m) with around 300 clear sunny days in a year. 5

FUNDING FOR 3000 MW • 1000 MW by Solar Purchase Obligation (SPO) on HT and LT Commercial consumers • 500 MW funded by the Government • 350 MW by promoting Solar Rooftops – – – –

Special scheme for Domestic rooftops All new Government Buildings to have rooftops All existing Government buildings to install in phases All Street Lights & Water supply installation with solar

• 1150 MW by encouraging REC (Renewable Energy Certificate) mechanism 10

Mechanism to Generate 3000 MW by 2015 The 3000 MW of Solar Power will be achieved through Utility Scale Projects, Rooftops, and under REC mechanism as follows Utility Scale (MW)

PROCUREMENT POLICY OF SOLAR POWER

• Through competitive/reverse bidding • Renewable Energy Certificate and Carbon Credits

12

SOLAR PURCHASE OBLIGATION(SPO) • 6% SPO Mandation for HT & LT Commercial Consumers • 3% till December 2013 & 6% from January 2014

13

SPO ADMINISTERING MECHANISM • Obligated consumers can choose to: • Set up captive solar plants (utility scale or rooftop) • Purchase solar power from IPPs within the State • Purchase Solar RECs from IPPs within the State • Purchase from TANGEDCO at Solar Tariff

14

PROMOTING DOMESTIC ROOF-TOPS

GENERATION BASED INCENTIVE (GBI) To encourage domestic consumers to put up rooftop solar installations, GBI is proposed for all Solar or Solar-Wind hybrid roof tops installed before 31 March 2014.

• Rs. 2/- per unit for first two years • Rs. 1/- per unit for next two years • Rs. 0.50 per unit for subsequent two years

15

POLICY INITIATIVES

• Net Metering to promote rooftop solar

• 100% Exemption from Demand Cut

• 100% Exemption from electricity tax for 5 years 16

TN SPECIAL SCHEMES • Energisation of 1,00,000 Street lights through Solar Power • Installation of 3,00,000 Home lighting systems in Green Houses for BPL families under “Chief Minister’s Solar Powered Green House Scheme”(CMSPGHS)

17

SOLAR HOME LIGHTS • Solar Home Lighting System in 3 lakh Green Houses @ 60,000 per year. • Solar system consisting 100Wp SPV Panel and 5 nos CFLs each 9W .These CFLs can be operated for 5 hrs a day.

• First project of its kind in India – Grid backed up – 5 year replacement Warranty

18

INNOVATIVE FEATURES OF SOLAR HOME LIGHTS



The solar home lighting system has innovative design having storage for only one day with provision for grid backup.



The Smart Hybrid Power Conditioning Unit in the system allows charging of battery from grid, only in rainy or cloudy days, when solar power is not sufficient to charge the battery in full.



The intelligent algorithm permits charging from grid only between 10am and 6pm.



Reduction in autonomy has resulted in considerable reduction in capital investment on additional battery & SPV panel capacity required for higher autonomy (usually 3 day autonomy is provided).



Since Tamil Nadu has more than 320 sunny days, no autonomy is provided.

SOLAR HOME LIGHTS

20

SOLAR STREET LIGHTS First project of its kind in India (both in terms of numbers and in features) • • • • • •

One lakh street lights in 5 years @ 20,000 per year. Grid backed up with auto changeover 20W LED Lights Auto dimming to 6W from 10pm-5am Remote Monitoring 5 year replacement Warranty

21

INNOVATIVE FEATURES OF STREET LIGHTS • The existing street lights so far powered from grid supply are powered from solar energy in clusters of 10 with provision for grid backup. •

The existing street lights with 40W tube lights & filament lamps are replaced with 20W LED Lights

• The Smart Power Conditioning Unit in the system allows charging of battery from grid, only in rainy or cloudy days, when solar power is not sufficient to charge the battery in full during 10am-6pm only • The street lights are dimmed to one third of full brightness from 10.00 pm to 5.00 am to save energy

22

23

ENERGISING 20,000 STREET LIGHTS THROUGH SOLAR POWER CATEGORY I •

Existing clusters of 10 Street Lights with tubelights/bulbs will be replaced by 20W LEDs & will be energized by a 500 Wp Central SPV power plant.



1800 plants to energise 18,000 lights.



Grid back up for reliable supply during low solar insolation period.

CATEGORY II •

Clusters of 10 new street light poles with 20 W LED lights will be erected along with new distribution Line and energized by a 500 Wp central SPV plant.



100 plants to energise 1000 lights

CATEGORY III Erection of 1000 Stand alone SPV street lights with 20 W LEDs at scattered locations.

24

REMOTE MONITORING UNIT •

To monitor PV Plant voltage, current and power, AC Mains Voltage, Battery Voltage, Battery charging current, Battery discharging current and Inverter load current at programmable time intervals from a Remote Central place(TEDA Office).



Daily fault report is generated & sent to the supplier for rectification within 2 days.



Tampering of Panel, battery & inverter housing is also monitored through tamper alarm and sms

25

INSPECTION AND MONITORING • • •



• • • •

Third Party Agencies for 1% sample Pre-dispatch inspection (PDI) at factories and 100% post installation inspection and certification. The entire project runs on a comprehensive Enterprise Resource Planning (ERP) system. Manufacturers submit the lots online through their login, PDI agency logs in and receives the random sample numbers of the components to be inspected and then submits inspection report. Similarly Installation report is submitted online by the vendors which enables Third Party Inspection (TPI) agency to inspect and submit its report online. All reports are processed automatically by ERP for acceptance or rejection. TEDA’s district engineers then do super-check inspections of the 5% random numbers generated by ERP. Payment is automatically made for each batch of 60 installations. Call Centre is being established through CMC for receiving the complaints and monitoring rectification by the suppliers
