Abstract
Government of India has come out with an ambitious target of 100 GW of using solar energy alone by the year 2022. To reach this target, innovative ideas are required to use the solar energy more effectively. For solar electricity generation, mainly two types of technologies are presently in use, namely, solar PV and solar thermal. Being a tropical country, India has large solar PV and solar thermal energy. More research is required on economic aspects to make the solar thermal competitive to solar PV. Towards this direction, in our present study we have simulated a solar thermal power plant using Parabolic Trough Collector (PTC) technology and normalized with 1 MW solar thermal power plant at Gurgaon near New Delhi. Through simulation, we have extended our study and computed the electricity generation possible at different locations of India. For this purpose with 1? × 1?spacing, computations have been carried out at 296 locations. The work is further extended for more detailed study at two representative states, namely, Gujarat and Tamil Nadu. In these two states, closer data points with 0.25? × 0.25? spacing have been considered at 273 locations for Gujarat and 197 locations for Tamil Nadu. Our results indicate a large potential of electricity generation using solar thermal energy in southern states of India, namely, Tamil Nadu, Karnataka, Kerala, southern and western part of Andhra Pradesh and eastern part of Maharashtra. Good potential has also been observed in eastern parts of Gujarat and parts of Madhya Pradesh and eastern part of Rajasthan. The annual potential ranges from 1800 MWh to as much as 2600 MWh. Major parts of northern states, for example Uttar Pradesh, Bihar, West Bengal, Punjab, Jammu and Kashmir have medium range potential. Here, the annual potential ranges from 1000 to 1500 MWh. Poor range of potential is observed towards eastern parts of India and north eastern states. Here, the electricity generation potential ranges from 600 to 1200 MWh. Our results are useful to solar thermal developer and decision managers.
Highlights
Water and energy can be considered as two eyes of any nation
Comparison of 1 MW Solar Thermal Plant In Figure 3, the results derived from modelling studies have been presented
If we compare our results with the installed plant near Delhi the annual electricity generation is nearly 2.85 times the actual generation (1365 MWh/annum)
Summary
Water and energy can be considered as two eyes of any nation. If the Government provides or facilitates these two items adequately, the nation grows. It facilitates the people to live comfortably and happily. Clean water and clean energy make all the people in this world healthy and help to live longer with fewer problems. Many nations in this world are starving for both clean water and the energy. Majority of the islands like Papua New Guinea, Fiji islands, parts of Andaman, Nicobar and Lakshadweep in India are suffering from acute shortage of electricity. At these locations, diesel generators are being used for electricity generation. The cost per unit electricity generation is nearly double as compared to the persons living on the main land
