Cajamarca, the region identified to start the rural electrification initiative "Luz en Casa" in 2009, had the highest rates of poverty and lack of electrification in Peru, which was the country with the highest number of population without access to the electricity service after Haiti.

Within this setting, we set the goal of proving that is was feasible, sustainable and affordable -with the appropriate technology and management- to bring a quality basic electricity service to low-income households in dispersed, isolated rural communities.  With this purpose, we implemented an innovative electricity service delivery model based on the provision of electricity with solar home systems in return of an affordable monthly fee. We achieve the Luz en Casa objective when exceeding 3,000 systems in operation.

The model has been improved with the inclusion of this service in the Peruvian regulation, the creation of the "Centro Luz en Casa" microfranchises owned by users specifically trained to give specialized assistance to benefited households, or the replacement of systems installed between 2009 and 2017 by more efficient third generation systems. In addition, we developed the side initiative "Luz Comunitaria" which brought electricity to 17 community centres (schools and churches) in the communities benefited by Luz en Casa.
