Frequently Asked Questions (FAQ)
Q1: What is the main goal of the REA’s solar projects?
The primary goal is to provide affordable, reliable, and clean electricity to the millions of Nigerians in unserved and underserved rural communities, thereby reducing energy poverty, stimulating economic growth, and improving quality of life.
Q2: How can a community apply to get a solar mini-grid from the REA?
Communities do not typically “apply” directly. The REA, through its programs like the NEP, issues calls for proposals to pre-qualified private sector developers. Developers then identify viable sites based on technical and commercial feasibility. However, communities can make themselves attractive to developers by demonstrating willingness to pay for power and ensuring security for the infrastructure.
Q3: What is the difference between a Solar Home System (SHS) and a Mini-Grid?
A Solar Home System (SHS) is a small-scale system designed for a single household or small business, typically powering lights, phones, and a TV or fan. A Mini-Grid is a larger, centralized solar power plant that generates electricity for an entire community, distributing it via a small local grid, similar to a miniature version of the national grid.
Q4: Are these solar systems given for free?
No, the model is not primarily based on free distribution. The REA’s strategy is to create a sustainable market. This involves providing grants or subsidies to private companies to lower the initial capital cost, which in turn allows them to offer systems to end-users at affordable prices, often through flexible payment plans like PAYGo for SHS or monthly tariffs for mini-grids.
Q5: How has the Solar Power Naija initiative impacted the average Nigerian?
It has impacted the average Nigerian by:
Providing cleaner and cheaper alternatives to petrol generators.
Enabling children to study at night and improving home comfort.
Powering small businesses, leading to extended operating hours and increased productivity.
