Consumer Study shows impact of mini-grids on Nigerian communities

A new consumer study from Nayo Tropical Technology Limited (NTT) shows the material impact of solar mini-grids in Nigeria on livelihoods, income and education.

NTT currently owns and operates four solar mini-grids, and is expanding its portfolio with 14 new mini-grids under construction. Shell Foundation has supported NTT since 2019 with co-funding from UKAID, USAID and PowerAfrica.

In June 2020, NTT contracted Seopad Nigeria Limited to conduct a consumer survey across its mini-grid sites to understand the impact of NTT products and services on consumers in rural Nigeria.

The conclusions were overwhelmingly positive, with improvements in business ventures, access to education for children, and more family time. Households felt that women and children benefitted most from using mini-grid power.
