India's Grid Connected Renewable energy installations

The statistics show a very fair growth in India's Renewable energy sector
According to Ministry of Power, as on January 2013 the total Renewable energy capacity of India is about 25,856.14MW (excluding hydro power projects) which accounts to a precise of 12.2% of the total energy produced in India

Solar Power:

With about 300 clear, sunny days in a year, India's theoretical solar power reception, on only its land area, is about 5000 Petawatt-hours per year (PWh/yr) (i.e. 5000 trillion kWh/yr or about 600 TW)The daily average solar energy incident over India varies from 4 to 7 kWh/m2 with about 1500–2000 sunshine hours per year (depending upon location), which is far more than current total energy consumption. The total installations by end of 2012 is 1200MW. India targets to increase its solar power capacity to about 10GW by 2017.

Wind Power:

The development of wind power in India began in the 1990s, and has significantly increased in the last few years. As of January 2013 the installed capacity of wind power in India was 18634.9MW

Hydro power:

India is endowed with economically exploitable and viable hydro potential assessed to be about 84,000 MW at 60% load factor. The current installed capacity of Hydro power counts to 39,416.40MW with 18.61% of the total energy production of India

Geothermal Power:


Though India has been one of the earliest countries to begin geothermal projects way back in the 1970s, but at present there are no operational geothermal plants in India.Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near tectonic plate boundaries. the potential geothermal provinces can produce 10,600 MW of power

It has been estimated from geological, geochemical, shallow geophysical and shallow drilling data it is estimated that India has about 10,000 MW of geothermal power potential that can be harnessed for various purposes.
Different orogenic regions are – Himalayan geothermal province, Naga-Lushai geothermal province, Andaman-Nicobar Islands geothermal province and non-orogenic regions are – Cambay graben, Son-Narmada-Tapi graben, west coast, Damodar valley, Mahanadi valley, Godavari valley etc

The MNRE said that grid-balancing problems have limited India's deployment of grid-connected solar and wind power plants, and the country is in talks with Germany, which has state-of-the-art technology in this field, to obtain the know-how.
