Connecting end of the mile-Malinyi, Tanzania
January to December, 2018
Eng. Matthew Josephat Matimbwi through Tanzania Renewable Energy Association (TAREA) and Associazione Microfinanza E Sviluppo Onlus (AMS)-Italy with financial support from Waldensian Evangelical Church-Italy and The Autonomous Province of Trento-Italy provided solar lights and connected community of Malinyi to the internet using solar photovoltaic technology.

The activities that have been realized in Malinyi are providing solar lights to Malinyi Bus Stand and Market Place, supplying solar electricity to Malinyi and Kipingo Secondary Schools, connecting to the internet Malinyi Teachers' Resource Centre (5 computers and solar photovoltaic system), provision of chairs to the primary schools of: Malinyi; Nawigo; and Makugira and training of 5 young people in solar photovoltaic technology installation and maintenance.

Installation of solar street light at bus stand
The solar street lights at Malinyi bus stand increased security to the passengers that spend overnight waiting for travelling, increased hygiene as there was a practice of urinating around in the night and increased the quality of business environment to the women food vendors.

Market solar lights
Market solar lights provide opportunity of increased working hours at the marketplace to 2 hours beyond the sunset; increased security of products left overnight at the market; and hygiene.

Solar photovoltaic systems at Kipingo and Malinyi secondary schools
Solar systems at the schools have contributed to the increase of the school performance as students can have opportunity of learning in the extended time in the evening and there is increased security around the school environment.

Internet for teachers' resource centre
Solar plant installed to supply electricity to five desk top computers and internet modem provides access to the teachers accessing information online. It will help teachers increase their knowledge and enable fast communication.

Chairs to 3 primary schools
84 chairs have been distributed to the 3 primary schools of Makugira, Malinyi and Nawigo. The chairs were provided to reduce the deficit of school chairs that existed in the village of Malinyi.

Solar lights for the households
Malinyi is connected to national grid. It is the fact that not all households are able to connect to the grid. Even those who are able to connect to the national grid are not yet connected. Project enables those families not yet connected, through VICOBA, to replace kerosene lanterns to improve the living environment and provide possibility of children studying at home in the evening.

The above achievement had been realized in the period of  2014-2017.

New project Finance 4 Sustainable Energy has been launched for the period of 2018-2020
