“…However, in the case of wind farms, the land taken up by the turbine towers and additional infrastructure such as roads is usually only 1-10% of the total land area and the remaining land can continue to be used for other purposes such as grazing, agriculture, and recreation (Fthenakis and Kim, 2009). For the purpose of this study I assume the land area actually disturbed to be 3% of the total in line with estimations made by Phadke et al (2012). The calculations are shown in the Appendix.…”

Modelling studies which project pathways for the future of energy in India currently have several implicit assumptions with regards to the social, institutional, and political changes necessary for energy transitions. This paper focuses on the specific question of land use change required for realising ambitious clean energy targets. Demand for land is likely to be a critical question in India's energy future given the challenges with land acquisition in the country as a result of high population density and significant rights enjoyed by landowners. Yet, there is a lack of literature relevant to India which makes a quantitative assessment of the land use impacts of different types of low carbon technologies. I calculate and compare the land requirements in India of ground based solar photovoltaic (PV) power, nuclear power, and wind energy. All three types of technologies are expected to grow substantially as a share of India's electricity mix in the coming years. The analysis suggests that land demands of ground based solar PV are likely to be substantial compared to wind energy and nuclear power, and some policy suggestions are provided which may help mitigate that challenge.

“…Ranchi, Jamshedpur, Devghar, Lohardaga and Chaibasa in Jharkhand, India and reported that the sites studied were unsuitable for wind to electricity generation on a large scale at 10 m above the ground but small-scale wind turbines can be installed to extract energy from low-speed wind. Phadke et al (2011) have reported Tamil Nadu as one of the potential states for harvesting 95% of the nation's wind energy potential. But they have not mentioned the detailed intricacies of possible variations in considering the topographical differences at various locations within the state.…”

Wind energy is one of the abundant, cheap and fast-growing renewable energy sources whose intensive extraction potential is still in immature stage in India. This study aims at the determination and evaluation of wind energy potential of three cities located at different elevations in the state of Tamil Nadu, India. The historical records of wind speed, direction, temperature and pressure were collected for three South Indian cities, namely Chennai, Erode and Coimbatore over a period of 38 years (1980-2017). The mean wind power density was observed to be highest at Chennai (129 W/m2) and lowest at Erode (76 W/m2) and the corresponding mean energy content was highest for Chennai (1129 kWh/m2/year) and lowest at Erode (666 kWh/m2/year). Considering the events of high energy-carrying winds at Chennai, Erode and Coimbatore, maximum wind power density were estimated to be 185 W/m2, 190 W/m2 and 234 W/m2, respectively. The annual average net energy yield and annual average net capacity factor were selected as the representative parameters for expressing strategic wind energy potential at geographically distinct locations having significant variation in wind speed distribution. Based on the analysis, Chennai is found to be the most suitable site for wind energy production followed by Coimbatore and Erode.

“…In addition, technology risk, which in this context means high resource variability coupled with a lack of conclusive resource assessments for India can present a greater challenge to wind projects than solar projects [32]. Wind power auctions in the U.K., Brazil, and South Africa, as well as coal-power auctions in India, have shown that flawed auction design and high completion risk can lead to a failure in deployment.…”

a b s t r a c tWe examined 20 renewable energy auctions in India and elsewhere to answer two questions: first, have auctions been effective; and second, how can they be designed to achieve India's renewable energy targets? The significant contributions lie in the larger sample size, use of secondary and primary research, and application of quantitative and qualitative analysis. We found that auctions are almost always cost-effective, with savings up to 58% from baseline feed-in tariffs. However, auctions may not always be deployment-effective, with only 17% of the auctions with greater than 75% deployment. We then examined how to best design auctions by assessing seven major risks, and found the following: first, for every 1% increase in total risk, deployment effectiveness decreased by 2% points; second, project specific risks have 60% greater impact than auction specific risks; and third, deployment effectiveness is most affected by auction design, completion, and financial risks. We also found that effectiveness of auctions in India can be improved by ensuring competition, improving transmission infrastructure, providing payment guarantees, using pay-as-bid auctions, including stringent penalties for delays, and introducing auctions in a controlled manner.
