Renewable Energy in India

� Wind energy occupies first with an installed capacity of about 18

GW as in November 2012.

Ranked 5th in worldwide wind installation capacity.� Ranked 5th 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.

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.

JNNSM Highlights

• Create favorable condition for solar manufacturing capability.

� Promote off grid/decentralized application of solar energy therebyempowering the people at grass root level.

� Technological innovations(R&D) to drive down costs towards gridparity.

� Create conditions through rapid scale up of capacity.� Create conditions through rapid scale up of capacity.

• R&D

• Detailed mapping of ground solar insolation particularly in highpotential solar regions.

• Establishment of dedicated Solar Radiation Resource Assessment(SRRA) stations to assess and quantify the ground level data onsolar radiation.

• Data processing , modeling and making of Solar Maps.

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•A combination of measured and satellite data helps in betterunderstanding solar potential areas .

• For preparation of accurate and reliable SOLMAPS

•Design & Performance Parameters

•To determine the bankability of the proposals

Solar irradiation data availability

• Information on Solar Radiation over India is provided by the wellreceived and widely utilized two volumes “Handbook of SolarRadiation Data for India” and “Solar Radiation over India”.

• First volume contains the results of measured values maintained byIndia Meteorological Department (IMD) and the second one givesderived values based on various meteorological parameters.derived values based on various meteorological parameters.

• MNRE in 2003 updated the “Handbook of Solar Radiation Data forIndia” with the latest data for the period 1986-2000.

• Purpose of these volumes were to provide a database for thedesigners of systems for harnessing the solar energy received at aplace.

• Very limited measured solar radiation data(by IMD) is available forthe country.

• Other sources are SEC-NREL data and satellite data(NASA,METEONORM,SOLEMI)

IMD -Solar Radiation measuring network.

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, 2011.

• 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.

Site selection criteria

• Area availability for future development.

• Free horizon.

• Strong network connectivity.

• Safety & Security.

• Electromagnetic interference.

• Easy accessibility to site.
