Executive Viability Abstract
This feasibility study evaluates the deployment of decentralized solar mini-grids across underserved rural communities in Nigeria. With over 80 million people lacking grid access, the project targets the 'Energy Gap' by providing reliable, 24/7 solar power to residential, commercial, and productive-use customers. The study indicates high technical viability and strong economic potential, supported by the Nigeria Electrification Project (NEP) and World Bank subsidies, offsetting initial high CAPEX costs to ensure long-term sustainability.

## Project Overview
The Nigeria National Solar Mini-Grid initiative aims to bridge the rural electrification gap through 100kW to 1MW solar-hybrid installations. These systems leverage Nigeria's high solar irradiance (5.5 kWh/m2/day) to replace expensive and polluting diesel generators.
## Market Analysis
Nigeria is the largest market for mini-grids in Sub-Saharan Africa. Market drivers include the high cost of alternative power (N600-N900/kWh for diesel), regulatory support from the Nigerian Electricity Regulatory Commission (NERC), and the 'Minimum Subsidy Tender' framework. The target demographic includes rural households, small-scale farmers, and micro-enterprises.
## Energy Demand Forecast
Demand is categorized into three tiers: 1. Basic Residential (lighting/charging), 2. Small Business (refrigeration/tools), and 3. Productive Use Equipment (PUE) such as agro-processing and water pumping. Forecasts suggest a 15% year-on-year growth in load as communities industrialize post-electrification.
## Capex Summary
Total CAPEX is estimated at $1,200 - $1,500 per connection. Major costs include: PV Modules (25%), Battery Energy Storage Systems (BESS) (35%), Power Electronics/Inverters (15%), and Distribution Infrastructure (25%).
## Revenue Model
The project utilizes a Pay-As-You-Go (PAYG) model integrated with smart meters. Revenue streams include: 1. Flat-rate tariffs (NERC approved), 2. PUE leasing, and 3. Connection fees. The 'Anchor-Business-Community' (ABC) model ensures a base load from industrial 'anchors' to stabilize cash flow.
