Integrated renewable energy resource assessment for Gujarat
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.
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.
- To carry out an integrated RE potential assessment for the state of Gujarat.
- To prepare an atlas of the available potential of RE resources like solar, wind, and biomass in Gujarat on a GIS platform, along with other essential elements such as land, water, demography, and infrastructure.
- To develop a RE atlas which can give users a bird's eye view of relative potential of the RE sources at the district level, in conjunction with existing network of electrical transmission, gas grid, and Narmada water canal network.
