  Improving access to energy services among the underserved requires
understanding the status quo in energy access and estimating future energy
requirements of energy service provision. In this paper, we present a novel
survey dataset collected in 2021 within the framework of the PeopleSuN project.
Across three Nigerian geopolitical zones, a total of 3,599 households and 1,122
small and medium-sized enterprises were surveyed. The sample is representative
of grid-electrified regions of each zone, excluding urban centres. Our surveys
collect data on demographic and socioeconomic characteristics, energy access
and supply quality, electrical appliance ownership and usage time, cooking
solutions, capabilities, and preferences. We encourage academic use of the data
presented and suggest three avenues of further research: (1) modelling
appliance ownership likelihoods, electricity consumption levels and energy
service needs in un-electrified regions; (2) modelling the integration of
decentralised renewable and battery storage solutions to address high usage of
diesel generators in peri-urban regions; (3) exploring broader issues of
multi-dimensional energy access, access to decent living standards and climate
vulnerability.
