Gujarat is one of the biggest states of the country having a large amount of waste land along with good solar radiation and wind flow for most of the year. Biomass, tidal, geothermal resources are also available in the state. Proper estimation of potential of any renewable energy technology is essential for planning and promotion of the technology. There has been some state level potential assessment of these resources under the Government of India programs for renewable energies. In the present study a focus has been made to go beyond the previous approaches, and an integrated approach has been made for RE potential assessment at the district level, considering the availability of the waste land, water, existing electrical transmission network, gas grid network etc. GIS has been used for land use land cover analysis and identification of wasteland for RE projects mainly the solar and wind power projects and mapping the RE potential over the state.

The broad objective of the study is:

  • To carry out the Integrated Renewable Energy potential assessment for the state of Gujarat,
  • To develop a renewable energy atlas in Web Application, which can give user a bird's eye view of relative potential of the RE sources at the district level along with existing electrical transmission network, gas grid network, Narmada canal network, and other infrastructures.

The methodology includes data collection on the previous estimates of Renewable energy potential in the state, analyzing those data, finding the shortcoming and need for improvements that can be made on potential assessment methods, and additionally the impact of technology development in to the actual potential. Various government agencies namely GEDA, GIDC, GETCO, CGWB, IMD, and other relevant institutions have been contacted for collecting the data required for the study. The LULC data of Gujarat were collected for the present year and analysed through the GIS.
