Are Off-Grid Solutions Really More Expensive for the Rural Poor?

A number you likely know: 400 million. That’s how many people live without electricity in India. And not coincidentally, most of these people are poorest of the poor and live in rural villages or hamlets. The presence of such an enormous population eager for something better has given rise to new commercial products and services such as solar lanterns, solar home systems, and, the subject of this blog, micro-grids.

For a place in the sun

How will solar energy be made to work in India? As I discussed in my previous article there are three key challenges. One, how will the country pay for solar energy in a situation where there is no money to pay for even the crashed costs of installation. Two, what is the best model for the distribution and use of this relatively expensive energy in a country where millions still live in the dark? Three, how should India combine the twin objectives of supply of clean energy and creation of domestic manufacturing capacities?

Keralaites, get your rooftop solar and save a bundle!

Kerala's 10,000 Solar Rooftop Programme is already in full swing with almost half (4700) rooftops signed up by mid-January 2013. Any Keralaite with 15 square meters of unshaded rooftop area can register ( to set up a 1 KW-peak system on their roof. The programme counts on each solar rooftop plant costing in total about Rs.

Clouds over solar

India’s solar power policy is now entering round two. And there is much that needs to be reviewed and reworked as the business of solar energy has seen massive turbulence in India as well as globally. In the first phase (2010 to 2013) of the Jawaharlal Nehru National Solar Mission (JNNSM) the target was to set up 1,000-2,000 MW of grid-based solar power in the country. By 2013, the country has indeed commissioned some 1,000 MW of solar power, but 700 MW of this target comes from the non-JNNSM state of Gujarat.

Talking Energy - On a lighter note

Every niche has its own lingo and Energy might have one of the most complicated ones around. Just as an example energy can be measured in six different ways! - Joule, Calorie, Tonne Oil Equvalent,  Watt hour, British Thermal Unit and Tonne Coal Equivalent. (For a good converter see: ).

Solar mini-grid and rooftop systems in Dayalbagh, Agra

Only half of the subsidy paid by the central government so far, laments the educational institute.  The system is not grid-interactive yet since there is no regulation on feeding electricity into the grid

The Radhasaomi Satsang in Dayalbagh is a spiritual center with a university campus (Dayalbagh Educational Institue), residential colonies, schools, hospitals etc. The residential colony and the Dayalbagh Educational Institute (DEI), now depend on solar energy besides conventional grid power for fulfilling their electricity needs.

Indian Rooftop Solar Rearing to go

Grid-connected solar power is growing fast in India, going from just a few megawatt (MW) in 2009 to over 1000 MW by mid-2012. 1000 MW of solar power can supply over 20 lakh Indians with electricity. Solar uses no fuel and is therefore one of the greenest ways of generating electricity. While many of the largest solar powered countries have focused mainly on rooftop installations (over half of German solar power capacity is on rooftops) almost all of India's solar power is generated through large plants installed on the ground (mainly in the semi-desertous areas of Gujarat and Rajasthan).

Reminiscing my visits of Swedish power plants

This November brought back reflections of my two study visits of Swedish power plants. The visits were done during the same months of previous two years while pursuing higher studies at a Swedish university. They were the Älvkarleby Hydroelectric Power Station and natural gas based Rya Combined Heat and Power (CHP).
