National Solar Mission - 20000 MW of Solar Power by 2022

Jawaharlal Nehru National Solar Mission is also known as the National Solar Mission. The mission was launched in Jan 2010 by the Government. This topic would be of importance in the IAS Exam for both Prelims and Mains.

For more details on Governments actions to protect the environment, candidates can go through the other missions of NAPCC formulated by the Government.

India is a tropical country where sunshine is available for longer hours per day and in great intensity. The daily average solar energy incident over India varies from 4 to 7 kWh/metre square with about 1500 – 2000 sunshine hours per year, depending upon location resulting in aggregate incident radiation of about 5000 trillion kWh/yr. This is too higher than the current total energy consumption. Hence solar energy has the potential to be a great source of future energy.

National Solar Mission – Funds for 100 GW Solar Power Capacity

Initially in India, the focus on solar technologies was bordered on the social and rural segment. Some institutes like IIT’s, National Physical Laboratory focused on developing solar, thermal and photovoltaic (PV) technologies. PV technology was being promoted extensively to meet the challenge of providing electricity for rural telecom network, village electrification and electrification of the unmanned railway crossing.

The Target for National Solar Mission

It had a set a target of 20,000 MW of grid-connected solar power by 2022. It was revised in June 2015 to 1,00,000 MW by 2022.

The 100 GW solar power capacity has been divided into:

  1. Rooftop solar electricity generation – 40 GW
  2. Large and Medium Scale grid-connected solar projects – 60 GW


  1. The total cost for up-gradation to 100 GW solar power capacity would be $ 94 Billion.
  2. Central Government is also planning to leverage bilateral and international donors, including green climate fund under the United Nations Framework Convention on Climate Change (UNFCCC).
  3. Using the bundling mechanism with thermal power.
  4. Investments would come from large Public Sector undertakings.
  5. Funds would be generated from Independent Power Producers.

Benefits of Using Solar Power

  1. Energy security
  2. Mitigation of adverse impacts due to Climate change
  3. Reduction in pollution and health benefits.
  4. Reduce dependence on fossil fuels that put a strain on foreign reserves and ecology.
  5. The solar manufacturing sector will get a boost
  6. Help in the creation of technology hubs for manufacturing
  7. Increased manufacturing capacity and installation are

Some of the improvements required in the policy

  1. Locate projects near towns and village clusters so that there will be the uninterrupted power supply.
  2. Minimise transmission losses
  3. In the medium to long term minimise the need for new investments in transmission infrastructure.

Government funding

  1. Government of India is providing Rs 15,050 crore as capital subsidy to promote solar capacity addition.
  2. This capital subsidy is for rooftop solar projects in various cities and towns, for viability gap funding based projects to be developed through the Solar Energy Corporation of India (SECI) and for decentralised generation through smaller projects.

The mission is made up of 3 phases,

Phase 1 – 2012 – 13

Phase 2 – 2013 – 17

Phase 3 – 2017 – 22

Targets are given below

  1. Install 1,00,000 MW of solar power by 2022.
  2. 40 GW rooftop and 60 GW through large and medium scale grid-connected solar power projects.
  3. To achieve 15 million sq metres of solar thermal collector area by 2017 and 20 million by 2022.
  4. To deploy 20 million solar lighting systems for rural areas by 2022.
S.No Targets / Application Segment Solar Collectors Off-grid solar applications Utility grid power, including rooftop
1 Target for Phase 1 (2010/13) 7 million sq mt 200 MW 1000 – 2000 MW
2 Target for Phase 2


15 million sq mt 1000 MW 4000 – 10000 MW
3 Target for Phase 3


20 million sq mt 2000 MW 20,000 MW

Implementation model

  1. Bundling scheme
  2. Generation Based Incentive (GBI) Scheme
  3. Viability Gap funding scheme

The mission also aims to reduce the cost of Solar Power Generation in the country through

  1. Long term policy
  2. Large Scale deployment goals
  3. Aggressive R&D
  4. Domestic production of critical raw materials, components and products, as a result, to achieve grid tariff by 2022.

Achievements of the National Solar Mission

  1. To reduce the risks of solar power producers, Solar Energy Corporation of India (SECI) was established as a major procurement agency.
  2. Creation of larger projects to bring down capital investments in solar power generation projects through the development of integrated solar parks so as to provide infrastructure for solar power plants.
  3. Renewable energy corridor was also launched to develop a dedicated transmission grid for areas with an abundance of sunlight or wind to create solar and wind energy.
  4. Solar radiation monitoring stations were set up across India.

Major Positive Developments since 2014

  1. The new Government as per its ambition to provide electricity for all, the target was revised for establishing grid-connected solar power was revised from 20 GW to 100 GW under the NSM.
  2. The huge quantum jump in targets generated huge demands for solar energy projects and equipment.
  3. 100 GW is divided into two major segments – a) 60 GW of grid-connected ground-mounted large solar power plants, typically above 1 MW capacity. b) 40 GW of rooftop solar power plants for generation of electricity.
  4. Emphasised to rope in Central and State Public Sector companies, defence establishments and others who started establishing projects on their unutilized land. To avoid the problem of limited land availability, innovative ideas such as floating solar power plants, solar power plants over canals, use of barren land for solar power plants are being promoted.
  5. Revised targets for Renewable Purchase Obligations (RPO), to ease the purchase of solar power, net metering, interstate power purchase by bulk consumers such as Delhi Metro.
  6. Focus on skill development and indigenous manufacturing through the establishment of Skill council for green jobs.

The above details would be of help to candidates preparing for UPSC 2020 exams from the perspective of mains examination.
