IIT-Madras invented indigenous way of low voltage, brown-out dc power distribution

IIT-Madras has developed an indigenous way of power distribution in which houses will be able to receive an uninterrupted 24 X 7 electricity. The project includes distribution of low voltage, brown-out mode of power distribution in which Alternating Current is also converted into Direct Current before supplying electricity to houses. Here, brown-out means is that say 10 percent of power is transmitted. Instead of 100 percent power cut you can have 90 percent power cut and meet the demand for a few critical devices in every home like fans, lights, TVs and cellphones. Under this project each house will receive 100 watts of DC power, which is sufficient to run 1 or 2 fans along-with 2 to 3 tube-lights and mobile charger.

Apart from this, some features are that houses covered under this project will also receive power through a separate line supplying Alternating Current to meet rest of their needs. Both lines will be separate and houses will get power supply through separate energy meters. Also, value of direct current is so low so that electricity boards will not be needing to cut power to do repairs.

The pilot project has been completed in which around 200 houses in Madurantakam have been chosen to implement and study the project.
