This dataset describes the core variables for the electricity produced by the Gbamu Gbamu minigrid system located in Ogun State Nigeria for the month ended April 2020. The data is collected originally by Rubitec Nigeria Limited,a renewable energy generation company in Nigeria. Some of the variables covered in the dataset include: cost of energy, kilowatt hours, minimum voltage, average voltage, maximum voltage, maximum current, true power, apparent power, power factor and power limit of energy produced.

The data were collected in Musanze district, Rwanda. The purpose of the study is to assess the impact of energy efficiency policies on future energy demand in secondary cities. That was processed by spss. The results showed that four energy sources predominate: electricity, charcoal, firewood and LPG. However, there were urban households with greater diversity of energy sources in urban households, also including electricity (97.89%), candles (44.21%) and liquefied petroleum gas, or LPG (37.89%). Charcoal use is much higher at 82.11%, whereas firewood use is only 29.49%. In order to minimize energy loss in urban households, this research suggests that similar studies in the future may focus more on obtaining previous data, if possible, the study could be conducted over years to use own primary data, or else obtaining as many years’ data as possible to forecast the future energy consumption accurately.
