Achieving 175 GW RE Target by INDIA With Extended 450 GW BY 2030 Ambitious Target

By -

The Indian government has kept a target of 175 GW installed capacity using different renewable energy technologies in the country. Currently, the total installed capacity of the country is 367.3 GW of which thermal is 230.72 GW, Nuclear is 6.78 GW, Hydro is 45.4 GW and RE is 84.4 GW as on 31.12.2019. For the month of December 2019 the electricity generated in different power segments is 86.1 BU in thermal, 3.6 BU in Nuclear, 8.9 BU in Hydro and 9.3 BU in RE [1].

Currently, the total renewable installed capacity is 57.472 GW (12.5 GW of solar i.e., 21.8% and 32.3 GW of wind i.e., 56.2%).  Depending upon the current installation frequency, we can forecast whether we can reach the target by 2022 or 2030. MNRE is exploring with new innovative approach for increasing the capacity of renewable energy in the country and promoting them for the same. [2]

Benefits with 175 GW RE target

 Reduces the carbon footprints in the country and promotes renewable energy technologies;

2. More focus on new technology development in renewable energy and increases the competition and demand for renewable energy in the Indian market. (With the increase in the competition, the solar and wind tariffs have declined to Rs. 2.45 and Rs. 3.50 per kWh);

3.  Development and adapting to new technologies can take place by increasing the usage of technology helps to overcome the issues and limitations. This helps in establishing a renewable energy grid and decentralized power in the country. Reduces peak demand in thermal power plants and reduces the major carbon emission reduction in the country.

India is running under deficit power of -0.8% as on December 2019 i.e. 1,304 MW. The peak demand requirement is 171,796 MW in which we can able to meet 170,492 MW of the peak met. As on Feb, 2020 the demand met during the evening peak is 161,135 MW and the maximum demand during the daytime at 09:30 AM is 171,206 MW and the peak shortage is 674 MW.[3]

From the above table, we observe that with the increase of renewable installed capacity, the plant load factor of coal and lignite-based thermal power plant demand is gradually decreased. With this, we can understand that by 2022 the renewable energy target may reach to 170 GW installed capacity.

Recently, India has committed to an ambitious target by extending the target to 450 GW of RE installations by 2030.

Note: This article will be updated on a timely basis with reference to the developments and changes taking place in the market.

Solar panels installed on the roof with a capacity of 11.5 MW in Punjab state in India India’s solar mission which has kept at a target of 175 GW and the government is trying to keep its word to generate power from all kinds of Renewable Energy Resources. As it is focused on Solar, Wind and Biomass power generation technologies. We all know that a roof is the zero cost of land and uses the space for solar panel installation. There is no requirement of a special setup is installing the solar roof. Depending upon the roof size and shading and direction of the sunlight is considered for setting up the solar panels. But, most of them have small or medium roofs that can generate in kiloWatts (kW) or Megawatt (MW) scale. In Amritsar, there is an installation od 11.5 MW capacity of a solar power plant which is completely covered with solar roof which will benefit 8000 households was built by Radha Saomi Satsang Beas (RSSB), a religious organization in Punjab.

In most of the western countries and developing countries are launching the new concept called the “ Recycling Malls ” in major cities and towns across their countries. The main objective of the recycle mart is to sell the used products (ex: used plastic, glass, paper, etc.). This is an innovative way of making things and helping in reducing environmental pollution in the surroundings across the globe.   There are different kinds of pollutions that are generated effecting Air, Water, Land, Food, Sea, Ocean pollutions. It is damaging the EARTH gradually and impacting directly and indirectly that are highly toxic and increase the scope of new harmful viruses etc.   Issue: Wastes are different types that are generated in the world which is mostly produced by man. Anything that is produced excess and unable to control is added into pollutant list. The recycling plants are getting adopted across the globe with different techniques, methodologies and Strategic ways in collection

Honda is one of the popular brands in the Indian automobile industry. with the Activa petrol scooter with multiple versions, the company is come up with an electric version which Indian consumers are awaiting for the same. Apart from their plans to launch the electric vehicle in the Indian market, some of the key points are strong enough for Honda can capture a great EV market share in the country. Kinetic Honda is the predecessor for Honda Activa which was a big hit in 90s.  Year wise Activa Models released by Honda:  2001,  2002,  2007,  2008,  2009,  2018,  2019,  2020,  2021 Some of the key advantages for Honda can be a great EV market giant compared with startups and OEMs due to the following: Charging facilities in service stations: As Honda has 334+ service stations [1] across various states in India, the majority of them are bigger compared to other two-wheeler service stations. So a large charging infrastructure network and facility can be developed which can provide easy ac

India is witnessing a new chapter in the growth of the renewable sector, mainly in the solar sector. Hence, any new breakthrough in the field of solar cells and solar power generation is beneficial for India. New technology is being developed in the University of Chicago within the confines of its chemistry laboratory by Professor “Luping Yu”. A new kind of solar panel was designed and manufactured which has a higher efficiency when compared with the currently running modules used for power generation. The given polymer solar cell consists of a new polymer, called "PID2". The new polymer improves the efficiency of electrical power generation by 15 per cent when added to a standard polymer-fullerene mixture. New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer a type of large molecule that forms plastics and other familiar materials which improved the efficiency of solar cells. The group also determined th
