Powering Nigeria’s Future: How to Fix the Broken Promise of Minigrids

By Dr Tobi Oluwatola

In a small village of Egororebet, just outside Jos, Nigeria, a solar-powered minigrid hums at dusk. But instead of glowing homes and bustling businesses, the panels cast shadows over empty wires. The batteries died years ago. Families still burn kerosene lamps. The community’s dream of electricity? A flicker, then darkness.

This scene repeats across Africa, where dozens of government and donor-funded minigrids—decentralized energy systems meant to power rural communities—are operating far below capacity or lying abandoned. The issue isn’t just a lack of investment or sunshine. It’s a web of systemic failures: shoddy construction by contractors, neglected maintenance, and a lack of accountability that leaves communities stranded, despite their willingness to pay for better service.

During visits to 40 minigrid sites conducted under the FCDO sponsored UK Nigeria Infrastructure Advisory Facility (UKNIAF) programme over the last 12 weeks, a pattern emerged. Contractors often cut corners—using second-hand solar panels, substandard wiring, or poor earthing that risks fires–doing just enough to scale the minimum standards. Systems were installed and commissioned without proper documentation such as the commissioning test results, as-built single line diagrams and layout drawings, key equipment manuals, key maintenance spares, and operations and maintenance schedules. Panels went uncleaned for months, dust slashing energy output. Minor faults, like a tripped inverter or loose connection, became permanent failures because no one took responsibility.

As Nigeria races to electrify 25 million people by 2030, these stalled projects offer urgent lessons. Here’s how to turn them around—and ensure future minigrids across the continent don’t suffer the same fate.

The Problem: Why Minigrids Fade

Most minigrids start with fanfare: solar panels rise, batteries are installed, and communities celebrate. But within years, systems falter. Lead-acid batteries—cheap but fragile—die under intense heat and irregular maintenance. Users, struggling to pay high tariffs, disconnect or bypass their meters. Others never plug in, because of the limited capacity of minigrid deployed to the community. Many others are not connected for productive use because their equipment is still fossil fuel-powered, and cannot afford to retrofit to electrically powered alternative.

But the rot often starts earlier. Contractors, eager to win bids, sometimes use second-hand equipment or skip critical steps like proper earthing systems, adequately sized cables, and protective devices, leaving systems vulnerable to damage. Many installations lacked even basic O&M plans. No one was hired to clean panels or fix faults. “The contractors disappeared after commissioning,” laments a village head in Kaduna State. Worse, one project in Ogun State failed because corroded, reused cables caused a fire outbreak.

The result? Millions of dollars in stranded assets, and villages slipping back into energy poverty.

Solutions: From Quick Fixes to Long-Term Shifts

1. Hold Contractors Accountable

Problem: Poor workmanship and shortcuts plague projects.
Solutions:

Enforce strict quality standards: Ban second-hand equipment in public contracts. Require certifications for solar panels and batteries.
Local technicians: Train community members—especially women—to handle basic maintenance. In Rwanda, “solar sisters” repair systems and earn steady incomes.
Third-party inspections: Independent engineers should verify installations before payment is released. NEMSA ought to play this role, but in many cases, it is not apparent that they did their jobs.
Long-term contracts: Tie contractor payments to system performance over 2–3 years, not just installation.

2. Better Tech for Tougher Conditions

Problem: Cheap, fragile tech fails under harsh realities common across Africa.
Solutions:

Ditch lead-acid batteries: Upgrade to lithium-ion, which lasts longer and handles heat better.
Remote monitoring: Install IoT sensors to alert operators to faults (e.g., low voltage, dirty panels).

3. Plan for Survival, Not Just Installation

Problem: No O&M strategy leads to collapse.
Solutions:

Mandatory O&M funds: Dedicate 20% of project budgets to maintenance. Kenya’s minigrid rules require this, ensuring cash for repairs.
Clean energy franchises: Partner with local shops to sell spare parts and offer repairs. Scale up approaches piloted in one scheme in Sokoto State that uses motorcycle taxis to dispatch technicians.
Community task forces: Assign villagers to clean panels monthly and report faults. A small stipend or free power can incentivize this.
Carbon Credits: Access to green bonds, finances, and bonuses for carbon mitigation
Metering: Adequate and secure metering infrastructure to guarantee payment collection and reduction in energy theft

4. Make Payment Easy—And Fair

Problem: Tariffs don’t match realities.
Solutions:

Pay-as-you-go (PAYG): Let users pay via mobile money, like airtime. Kenya’s M-KOPA uses this to sustain 250,000 solar systems.

Anchor clients: Partner with businesses (e.g., rice mills) to guarantee revenue. In Benue, a minigrid powers a fish farm that covers 40% of its costs.

5. Communities Must Own the Power

Problem: Projects imposed from above breed distrust.
Solutions:

Co-design systems: Involve locals in site selection and tariff setting. In Niger State, women’s groups helped design a minigrid that now powers a shea butter cooperative.
Energy literacy: Teach communities how electricity can boost incomes—e.g., nighttime tutoring, charging shops, or irrigation.
Renewable Energy Users Cooperatives–REUCS: Create community associations to take ownership of the project by carrying them along from the design, and construction to the commissioning phases.

Policy Reforms: Breaking the Cycle

Nigeria’s Rural Electrification Agency (REA) and state governments must:

Blacklist rogue contractors: Publish names of firms delivering substandard work.
Simplify standards: Adopt clear, enforceable guidelines for minigrid design and O&M.
Link grants to sustainability: Fund only projects with realistic O&M plans and community buy-in.

Economic Catalysts: Linking Minigrids to Growth Sectors

To truly thrive, minigrids must go beyond basic lighting—they should power industries that drive prosperity, such as Data Centres and Digital Hubs; and Agriculture and Agro-processing hubs – two sectors with transformative potential:

1. Data Centers and Digital Hubs

Nigeria’s tech sector is booming, but unreliable power stifles innovation. Minigrids can unlock rural digital economies:

Data Centers: Deploy small, energy-efficient data centers powered by minigrids to serve local businesses, schools, and government offices–especially in the Universties. These hubs can offer cloud storage, internet services, and IT training. Globally, we have 60GW of data centers and are on track to build another 10GW this year but they are mostly in North America, Europe, and Asia. Some of the new capacity can be built in Africa otherwise, we have the same inequality in intelligence infrastructure as we have had in the last 100 years of electricity infrastructure.
Hybrid Systems: Pair solar with lithium-ion batteries and backup generators to ensure 24/7 reliability for critical infrastructure. In Rwanda, a solar minigrid in Bumba supports a tech hub where young entrepreneurs code and stream courses.
Job Creation: Data centers need technicians, security, and admin staff—roles that can be filled locally with skill-based training and support.

2. Agriculture and Agro-Processing

Agriculture employs 70% of Nigerians but suffers from post-harvest losses and low-value exports. Minigrids can revolutionize this:

Cold Storage and Processing: Power cold rooms to preserve tomatoes, fish, or dairy, reducing waste. In Kenya, minigrids run by Powerhive support avocado oil processing, doubling farmers’ incomes.
Electric Irrigation: Replace diesel pumps with solar-powered systems, cutting costs for smallholder farmers. A project in Katsina uses minigrids to irrigate maize fields, boosting yields by 30%.
Value-Added Products: Install electric mills, grinders, or oil presses to process crops locally. A shea butter cooperative in Niger State, powered by a minigrid, now exports directly to global markets.
Policy Support: Offer tax breaks for agribusinesses using minigrids and fund pilot projects linking farmers to clean energy.

The Bigger Picture: Electricity as a Catalyst

Functional minigrids aren’t just about lightbulbs. They’re about students studying after sunset, clinics refrigerating vaccines, and farmers irrigating fields. When minigrids work, they lift entire economies.

But sustainability requires humility. “We’ve learned that installing a minigrid is the easiest part,” says a developer in Niger State. “Keeping it alive is the real test.”

A Call to Action: Shift from counting megawatts to monitoring and measuring impact

Nigeria’s minigrid challenges reflect a more widespread struggle across the continent and are fixable—with accountable contractors, smart maintenance plans, and communities in the driver’s seat. The goal isn’t just to build more systems but to ensure these systems are fit for purpose and the last the test of time.

The status quo of elaborate launches and failed projects is not an option. Donors and public officials must shift from counting megawatts to monitoring and measuring impact: How many businesses opened? How many batteries survived five years? How many families still pay bills?

The world is watching. If Nigeria cracks this puzzle, it won’t just electrify villages—it’ll light a path for the 600 million Africans still living in the dark.
