The Center for Study of Science, Technology and Policy is developing a Renewable Energy (RE)

Atlas for India. This platform allows for visualisation and first-cut analysis of national and state

level potentials across various RE sectors such as solar, wind, bio-mass and pumped hydro. It is

intended to act as a common platform for decision-makers, policy researchers, academia and

industry to visualize renewable energy potential within India.

The platform is available at: http://darpan.cstep.in/reatlas/

The tool (so far) has been broadly categorized into two segments namely Solar and Wind. The

solar category comprises of both Concentrated Solar Power (CSP) and Photovoltaics (PV),

whereas wind category comprises of both Off-Shore and On-shore wind potentials. This tool

provides land parcel details at taluk level for each state in India. The tool is freely accessible and

doesn’t require any login credentials.

1. Homepage

The landing page of the application shows the aggregate national solar and wind potentials. As

user zooms in (double click), the map displays the state level solar potentials. On clicking the

icon inside any state, potentials in each district of that particular state are shown in a panel on

the right.

Important Note: Only waste lands have been considered for estimating the solar potentials.

Similarly, for the wind potential in a state, one can select the wind tab at the top of the page.

Important Note: Only agricultural land and wastelands have been considered for estimating the

wind potentials.

2. Analysis

In order to do any analysis, a user can click on “Analysis” button on top most right corner of the

homepage. This will take the user to the analysis page, with solar selected by default.

The user can see two tabs, namely

1. Data Layers

2. Site Selection




3. Site Selection for Solar

Switch to “Site Selection” in order to know more details about particular land parcels. There are

two ways to achieve this: one can navigate to particular taluk by selecting desired state and

district and click “Load” button which shows all available land parcels in that taluk.

On clicking the “Load” button, all parcels that meet the selection criteria are shown. The user

can select a particular parcel (the selected parcel turns yellow). Information shown includes

area of the land parcel and gross potential of the parcel based on the technology chosen. The

“Utilization” slider allows a user to estimate the actual amount of the potential he/she expects.

This estimate should factors in land utilization, contours and topography, possible finances

available etc. The net potential is therefore the useful piece of the parcel.




4. Techno-economics (Solar PV only)

Once a parcel has been selected, a user can perform techno-economic analysis by first

downloading a configuration file using the download icon and then clicking on “Upload the

config file for Techno-Economics”.

This will take the user to the CSTEM PV Web tool, where he/she can login or choose “Continue

as guest”. Selecting the upload file icon will input all the necessary data (including latitude and

longitude, chose technology type, 8760 hours of solar irradiation etc.). The user can then check

financial and technical parameters in detail.




5. Installation

The user can now click “Install” and the details will show up in a panel on the top-right. (“Install

operation colours the particular parcel in Green). This process can be repeated for multiple land

parcels which make a scenario for meeting the requirements.

6. Data Layers

Data layers is subcategorized into

1. Base layer

2. Overlays (Added on top of Base layer)

Base layers sub-category presently consists of Openstreetmap, Solar Insolation, Wind Power

Density (for 100m hub height) and satellite overview. In addition to these, this section also

contains choropleth maps like potential PV and CSP parcels (wasteland only) across India.

Overlays are several additional layers that provide useful information to the user. These can be

switched on and off as per the user’s convenience.




7. Acknowledgements

We gratefully acknowledge several institutions whose generous support made possible the RE

Atlas. The core grant provided by Think Tank Initiative of International Development Research

Centre (IDRC), and Oak Foundation helped us build the expertise in geo-spatial analysis and

acquire various data sets and tools. Shakti Sustainable Energy Foundation grant enabled us to

procure wind related data and add Integrated Resource Planning as a component to model the

integration of RE with conventional power sources. Ministry of New and Renewable Energy

grant enabled us to develop CSTEM, which is an engineering-economic analysis model for solar

thermal technologies. We further used the grant from Department of Science and Technology

(under Indo US Joint Clean Energy R&D Centre, SERIIUS) to add engineering economic analyses

of solar PV technologies to CSTEM.
