Data collected as input to the geospatial least-cost plan for universal electricity access by 2030 developed as part of the ESMAP funded World Bank Nigeria Electricity Access Project (NEAP). The dataset covers the service area for the Kaduna Electricity Distribution Company (KEDCO) Nigeria. The data was downloaded on April 7th, 2016 for the four states of the Kaduna Electric utility coverage area: Kaduna, Kebbi, Sokoto and Zamfara. The data source for the nightlights data is from : Earth Observations Group (EOG) at NOAA/NGDC https://ngdc.noaa.gov/eog/viirs/download_dnb_composites.html The data was downloaded for the range of 20151101 to 20151130 2015. The data represent the light outputs from cities, towns, and other sites with persistent lighting, including gas flares. Ephemeral events, such as fires have been discarded. Then the background noise was identified and replaced with values of zero. The data was downloaded on 1/28/2016 for the West and North Africa region and then further clipped to only include the four states of the Kaduna Electric utility coverage area: Kaduna, Kebbi, Zamfara and Sokoto states.
