Mera Gao MicroGrid Power among the 10 emerging tech list of Technology Review

Electricity, which is a basic necessity in developed world is a luxury to millions of Indian living in rural areas. Energy Scenario in India is complex, on one hand close to 400 million mostly rural residents do not have access to power, on the other hand where power is available, almost 50% generated energy is lost duet to poor electrical infrastructure and power theft. At the same time, the economy is growing at 7-8% per year, and the demand for energy is skyrocketing for all practical purposes. Due to acute energy shortage, global climate issues, and scarce resources India cannot pursue traditional model for energy generation and distribution.

The country has to adopt new model such  as distributed generation or MicroGrid, where sustainable energy is generated and distributed in local area. Nowhere is so practical and sustainable than rural India, where energy demand is up-to basic needs like lighting bulbs, cooking, or charging cellphones. Such needs, which are at present met by expensive and/or polluting fuel like Kerosene and Woods, provide untapped market for clean tech companies, especially, when government is facilitating this opportunities through National Solar Mission.

One such company known as "Mera Gao MicroGrid Power (MGP)", which serves this "Bottom of Pyramid " market was recently selected for its unique MicroGrid technology as one of the 10 emerging technology of 2012 by the Technology Review.  Mera Gao Power provides seven hours of electricity to per household that powers two LED light bulb and a mobile charging station through its Solar MicroGrid for the cost of $0.50 per week. Founded by two US born entrepreneurs, Nikhil Jaisinghani and Brain Shaad, It primarily operates in Uttar Prades (UP), which is one of the poorer state in India where shortage of electricity is so acute. According to Technology Review, the falling cost of LED and Solar panels has made it possible to operate MicroGrid that provides services for which the poor can afford. The MeraGaoPower uses just four solar panel to supply electricity to 100 households at the total cost of $2500. The grid uses 24 volt DC throughout, which allows to use aluminum wiring instead of the expensive copper wire. To effectively minimize the loss of energy, the village is carefully mapped before installation for efficient arrangement of distribution lines.

According to Jaysinghani, the mapping and design is their biggest innovation. The company, which deployed the first commercial micro-grid in last summer, is now supplying power to eight more villages and has plan to scale upto 50 villages by end of this year. For which, it has received $300,000 grant from USAID, however,  according to guardian, the founders have vision to supply micro-grid based power to 100,000 household by 2016 requiring many more investment in the future. The Distributed Energy Generation (DER) is $2 billion potential market in India considering 114 million people spend $75 for such services per month, according to World Resource Institute (WRI),a Washington DC based think tank.

For Villagers, who don't have access to grid electricity, this means cheap quality power at home and relief from kerosene, which is pollutant and health hazard, for which, often they have to pay expensive price due to black marketing.  The mobile charging station provides another relief from traveling long distance for the sake of charging phone and paying expensive price. According to Guardian report,  for the villagers it is just more than light, it is an opportunity to do more after the dark. The report describe what villagers feels in their own words. 


"I wanted this light straight away, as it enables me to cook after dark," said Muni-devi, a grandmother from the village of Kaharanpura who makes samosas to sell at the local market. "With longer hours to work, I can earn more for my family each day."

Santram Pal, a father of four from the neighboring village of Chuck, was exuberant, too. "I'm very happy with the lights," he said. "Now my children can study at night and my house won't go so black inside from the smoke. Thieves won't come either."

India launches its first Smart Mini-Grid System

Renewable Energy Based Smart Mini-Grid System Commissioned Minister of New & Renewable Energy, Dr. Farooq Abdullah and Minister of Power, Shri Sushilkumar Shinde jointly commissioned the India’s first of its kind Renewable Energy Based Smart Mini-Grid System at TERI Retreat in Gurgaon today. The system has been developed with the support from the Ministry of New & Renewable Energy. Speaking on the occasion Dr. Farooq Abdullah said that India needs to tap all sources of energy in order to meet its growing demand for power. He said that the country must have strong safeguards so that it gets the best technology and also develops it indigenously. Shri Sushilkumar Shinde said that renewable energy is important as it reaches unreachable areas. He said that smart mini-grids will be very useful for stand-alone projects in villages and inaccessible areas. Secretary, Ministry of New & Renewable Energy Shri Deepak Gupta and Director General, TERI Dr. R.K. Pachauri were also present on the occasion.

A Smart Mini-Grid (SMG), or Micro-Grid, is an intelligent electricity distribution network, operating at or below 11 KV, where the energy demand is effectively and intelligently managed by diverse range of Distributed Energy Resources (DERs) such as solar PV, micro-hydro power plants, wind turbines, biomass, small conventional generators such as diesel gensets etc in combination with each other through smart control techniques.

Globally, managing existing energy resources and demand in an optimal and efficient manner has become the need of the hour. Enhancing energy-security and energy-access, particularly in emerging economies is one of the major challenges that one has to deal with. Smart grid has been evolved as one of the solutions to tackle these challenges. Advanced sensing, communication and control technologies are used in smart grids these days for not only generation and transmission of power but also distribution and utilization of electricity in a more intelligent and effective manner.

Such an application will not only foster the effective inter-connection and utilization of multiple renewable energy resources but would also help in advancing access to energy to the last mile in the most optimum way by improving the efficiency of the overall system. The Smart Mini-Grid system has a great potential in large commercial and industrial complexes, hospitals, shopping malls/ complexes, apartments, residential complexes, educational institutions, remote un-electrified as well as electrified locations to ensure maximum flexibility, reliability and safety.

The project was sanctioned to TERI under the aegis of Asia-Pacific Partnership on Clean Development and Climate (APPCDC) in March, 2009 with the contribution of Rs.87 lakhs from the Ministry of New & Renewable Energy. The project was completed with the technical collaboration of the Solar Energy centre under the Ministry of New & Renewable Energy. The smart mini grid has been deployed at TERI Retreat building in which 3.2 kW wind generator, 10.5 kW solar PV power, 1 kW thin film, 2 kW SPV systems, 100kW biomass gasifier and diesel generator have been integrated to demonstrate optimal evacuation of renewable power.
