Energy from conventional sources like coal, oil, natural gas, etc. is limited in quantity, and if depleted at the present rate, it will be exhausted in the coming decades, therefore, making renewable sources of energy as one of the critical ways for the future. Gujarat is one of the biggest states of the country, having a large amount of waste land along with good solar radiation and wind resource for most part of the year. Apart from solar and wind, there is, biomass, tidal, and geothermal resources that are also available in the state.

Proper estimation of potential of any RE (renewable energy) resource is essential for proper planning and promotion of the technology. In this study conducted by TERI and TERI University, an integrated approach for RE potential assessment was made at the district level, considering the availability of waste land, water potential, existing electrical transmission network, and gas grid network etc.

For RE assessment in Gujarat, a logical approach was adopted. The methodology included data collection on the previous estimates of RE potential in the state, analysis of that data, finding shortcomings and improvements that can be made, and addition of potential areas due to technological development. The primary objective of this exercise was to prepare an atlas of the available potential of RE resources like solar, wind, and biomass in Gujarat on a Geographic Information System (GIS) platform, along with other essential elements such as land, water, demography, and infrastructure.

The present RE assessment data available is not very user-friendly as it is both voluminous and scattered. The assessment of potential of a RE resource is dependent on many factors apart from the resource availability, which include -- land use and land cover, availability of water, transmission and distribution network, load centres, demographic information, and industrial clusters. This study at TERI incorporated all these factors in assessing the RE resources.

Various modes of renewable energy
Harnessing renewable energy
Based on this comprehensive study, it has been analyzed that there is a much higher potential for development of RE systems in Gujarat. The GIS-based land use/land cover study gave an idea about the quantity of the land which is suitable for RE project installations. The study helped in identifying the districts where there is potential for concentrated solar power (CSP) plant, solar photovoltaic (SPV) plant, wind, biomass, and also the probable SPV-Wind hybrid plant development for optimized utilization of land.

The analyzed district-wise RE resource potential on the GIS platform, incorporating the layers of electricity grid network, gas grid network, ground water and surface water, (Narmada canal route) etc, will be a very useful tool in planning of the renewable energy sector development in the state. The integrated approach gives logic for selection of the RE technology (wind, solar, biomass, and others) as per the strength of the resource availability in that particular area. It is envisaged that this integrated approach of RE resource assessment and the RE resource maps developed based on this study will be a very effective tool.
