Restructured Accelerated Power Development and Reforms Programme(R-APDRP)

The Restructured Accelerated Power Development and Reforms Programme (R-APDRP) is being implemented in TANGEDCO. The focus of the programme is the establishment of reliable and automated systems for sustained collection of accurate base line data and the adoption of Information Technology in the areas of energy accounting , besides reduction of Aggregate Technical & Commercial (AT & C) losses. The project area covers towns and cities with population of more than 30,000. The programme consists of two Parts namely Part – A and Part – B scheme works.

Part - A Scheme Works

Part – A includes the projects for establishment of baseline data and IT applications for energy accounting/auditing and IT based consumer service centres. MoP/GOI has already sanctioned projects for implementation of Part-A in 110 towns of Tamil Nadu at a total cost of Rs.417 Crores. MoP/PFC have also notified that the following Seven towns/cities, (having population of more than 4 lacs as per 2001 Census and annual input energy of the order of 350 MUs) of Tamil Nadu are eligible for implementation of SCADA/DMS under Part-A. 1) Chennai, 2) Madurai, 3) Coimbatore, 4) Tiruchy, 5) Salem, 6) Tirunelveli and 7) Tiruppur. The total sanctioned cost of SCADA/DMS projects is 182.17 crores

Part - B Scheme Works

• The Part – B scheme work consists of distribution strengthening work which involves implementation of High Voltage Distribution System to reduce the losses to the maximum extent possible. TANGEDCO is planning to reduce the losses to less than 15% by implementing R-APDRP.

• Part-B schemes for 87 towns have been sanctioned in five slots for a total of Rs. 3279.56 crores.

MUNICIPAL SOLID WASTE

MNRE is promoting setting up of waste to energy projects in the country through 2 schemes namely.
(1) National programme on energy recovery from urban & Industrial wastes.
(2) United National Development Programme (UNDP)/Global Environment friendly (GEF) assisted project on development of high rate biomethanation processes as a means of reducing Green house Gases Emission.

Biomethanation

It means a process which entails enzymatic decomposition of organic matter by microbial action to produce methane rich biogas.

Waste to energy or Energy to waste

It is the process of creating energy in the form of electricity or heat from the incineration (the combustion of organic material such as waste) of waste source. Waste to energy is a form of energy recovery. Most Waste to energy processes produce electricity directly through combustion or produce a combustible fuel commodity such as methane, methanol, ethanol or synthetic fuels.

VEGETABLE SOLID WASTE

Chennai Metropolitan Development Agency(CMDA) has installed a 250 KW Vegetable Waste based power plant at Koyambedu Whole sale Vegetable Market in Chennai.

Advantages

• 1. The quantity of wastes is reduced by nearly 60%-90%,depending upon the waste composition and technology adopted
• 2. With less wastes to dispose of, the demand of landfills is reduced, thereby saving land, which is already scarce in cities
• 3. Environmental pollution is reduced
• 4. Energy is obtained from the waste.
• 5. The slurry produced by biomethanation technology serves as a good fertilizer.
