1 MINISTRY OF NEW AND RENEWABLE ENERGY Presented by R. Sasi Kumar Scientist, SRRA, C-WET National Solar Energy Summit-2012 DSIIDC,New Delhi (13-14/12/2012) CENTRE FOR WIND ENERGY TECHNOLOGY

2 Renewable Energy in India Wind energy occupies first with an installed capacity of about 18 GW as in November Ranked 5 th in worldwide wind installation capacity. MNRE/CWET has carried out dedicated wind resource assessment about 700 locations covering the entire country. Indian Wind Atlas has been published by MNRE/CWET in collaboration with RISO,Denmark.

4 Solar Energy-JNNSM Solar Energy has great potential in India as future source of energy. India is a tropical country endowed with vast solar energy potential. Government of India initiated Jawaharlal Nehru National Solar Mission (JNNSM) program in 2009 to provide ecologically sustainable growth. Major objective of JNNSM is to establish India as a global leader in Solar Energy.

5 JNNSM Highlights Create favorable condition for solar manufacturing capability. Promote off grid/decentralized application of solar energy thereby empowering the people at grass root level. Technological innovations(r&d) to drive down costs towards grid parity. Create conditions through rapid scale up of capacity. R&D Detailed mapping of ground solar insolation particularly in high potential solar regions. Establishment of dedicated Solar Radiation Resource Assessment (SRRA) stations to assess and quantify the ground level data on solar radiation. Data processing, modeling and making of Solar Maps.

6 JNNSM.. Application segment Solar collectors Off grid solar application Utility grid power, including roof top Target for Phase I ( ) Target for Phase 2 ( ) Target for Phase 3 ( ) 7 million 15 million 20 Million sq. meter sq. meter sq. meter 200 MW 1000 MW 2000 MW MW MW MW

7 Why Measurements? Ground measured data is more accurate but costly. Quantification of the ground data. A combination of measured and satellite data helps in better understanding solar potential areas. For preparation of accurate and reliable SOLMAPS Design & Performance Parameters To determine the bankability of the proposals

8 Solar irradiation data availability Information on Solar Radiation over India is provided by the well received and widely utilized two volumes Handbook of Solar Radiation Data for India and Solar Radiation over India. First volume contains the results of measured values maintained by India Meteorological Department (IMD) and the second one gives derived values based on various meteorological parameters. MNRE in 2003 updated the Handbook of Solar Radiation Data for India with the latest data for the period Purpose of these volumes were to provide a database for the designers of systems for harnessing the solar energy received at a place. Very limited measured solar radiation data(by IMD) is available for the country. Other sources are SEC-NREL data and satellite data(nasa, METEONORM,SOLEMI)

11 SRRA Implementation Under JNNSM (R&D), SRRA Program was sponsored by MNRE in 2011 and implemented by C-WET, Chennai. An exclusive SRRA unit has been established at C-WET. 51 SRRA stations in 10 States and 1 Union Territory have been established between May 2011 to October, A Central Receiving Station (CRS) has been established at C-WET. Data from all SRRA stations are transmitted through GPRS to the CRS at C-WET.

12 Site selection criteria Area availability for future development. Free horizon. Strong network connectivity. Safety & Security. Electromagnetic interference. Easy accessibility to site.
