## Project Overview
Analysis of electricity infrastructure, generation capacity, and electricity access across Nigerian states using SQL and Power BI
## Tools Used
* **MySQL:** Data cleaning, standardization, and view creation.
* **Power BI:** Data visualization, interactive dashboard design, and DAX modeling.
* **Excel:** Initial data retrieval and null value handling.
## Datasets
* **State Electricity Access Dataset:** Contains the electricity access rate (%) for rural and urban areas across Nigerian states over a 5-year period (2018–2023).
* **Grid Infrastructure Dataset:** Details state-allocated infrastructure, including grid type, plant type, voltage capacity (real and apparent power), transmission length, year commissioned, and functional status.
* **Nigeria Energy Analysis Dataset:** A merged, analytical dataset combining access and infrastructure records via SQL joins on the state level to uncover deep distribution trends.

## Key Insights
* **Capacity Leadership:** Lagos State significantly dominates the national power generation capacity.
* **The Energy Mix:** Gas-powered plants make up the overwhelming majority of the current energy infrastructure.
* The Infrastructure Disconnect:** Higher infrastructure allocation in a state does not inherently guarantee a proportionally higher electricity access rate for its po …
