micro-grids: powering the future

Micro-grids spread across Africa

Communities in developing countries (such as India and countries in Africa), especially those in remote locations, benefit from the deployment of micro-grids. As African nations push for rural electrification, they look to micro-grids as a solution to the problem. Micro-grids that use renewable energy are more cost effective and safer compared to diesel generators and kerosene, that are widely used in Africa today. Kerosene often uses up to 20% of an average African’s income, can cause fires, and unhealthy air quality.

A medium-sized solar power system with battery storage, on other hand,  can be easily used by over 50 households, an entire village, in many rural locations in Africa. Smaller, individual units, can power single, or a few, households. The power can be used for lighting, cell phone charging, cooking, etc…

Micro-grids are important for remote communities in Africa. Electrification of rural villages has been made possible through them. Power needed for water pumping, and purification, is done with the help of various micro-grids in Africa and other parts of the world. Mobile communication has a wider reach in the continent through telecom towers that are powered with micro-grids.

Micro-grids are cheaper than building power lines into forests and mountains, especially in the most remote locations in Africa. Poor communities in other third world countries will also benefit from having micro-grids installed, especially when the utility grids don’t want to build long power lines to connect them to the grid.

Many African rural communities have already built micro-grids as their energy source. Every time a new installation is made, the skill base of the locals is developed. Their infrastructure is improved as well. However, despite the recent momentum of micro-grids, one of the reasons there are not enough micro-grids in Africa is because of the prohibitive cost and lack of reasonable financing. Policy is needed to ensure that they are more affordable to the poor, remote villages in the continent.
