The Baikampady Mangalore Microgrid is a microgrid in India by SELCO foundation in Karnataka.
About the site
The entrepreneur who owns and operates the micro-grid system inherited the property from his father. The land is used as a plantation for coconuts, bananas, and other plants. Previously, the owner rented land to laborers who lived in makeshift tarpaulin tents. Due to a court order and community pressure, the owner was required to construct basic apartments for the resident laborers. Prior to installing the mini-grid system, residents would primarily use kerosene for light at a cost of 150-200 Rs per month. The kerosene was difficult to procure and poses health and safety risks. Residents would pay an additional 60-70 Rs per month for mobile charging. Grid power is available at the site, but there were a number of drawbacks to directly using the grid. First, government agencies do not recognize the site as a formal settlement so there was a regulatory risk to installing grid electricity. Second, the electricity service in this area is not reliable. And finally, the electric service provider charges a minimum fee for each meter even if no power is consumed. As this housing is used by migrant day-laborers, the houses are not fully occupied year-round. A solar PV micro-grid was therefore suggested, making use of the land-owner to build a sustainable model.
