How IEEE Smart Village Sparks Solar Revolution in Rural Cameroon
Breaking: Solar Minigrids Bring First Lights to Cameroon's Remote Mountain Villages
For decades, children in the rural village of Mbem in northwest Cameroon knew only moonlight after sunset. That changed when Renewable Energy Innovators (REI) Cameroon began deploying solar minigrids with support from IEEE Smart Village. The first systems now power homes and businesses, ending a 30-year wait for electricity.
“When the minigrid came on, it was like a new world,” says Jude Numfor, CEO of REI Cameroon, who grew up in Mbem. “Our community went from zero electricity to a reliable, clean power source in just a few months.”
Mission Sparked by a Single TV
Numfor’s drive to electrify his homeland began in childhood. “There was one person in the village with a petrol generator and a small television. When he turned it on, all the children would run to his house and peep through the window,” he recalls. That memory led him to cofound REI Cameroon in 2006.
Today, the company designs, installs, and maintains solar minigrids using photovoltaic panels and battery storage. The systems generate 50-hertz AC power distributed through smart meters. In 2017, IEEE Smart Village granted funding to expand operations and refine REI’s business model.
Open-Source Metering Ensures Transparency
A key innovation from the partnership is open-source metering. Unlike proprietary utility meters, this community-driven system allows users, researchers, and utilities to view and customize data collection. “It ensures transparency in billing, consumption tracking, and grid management,” Numfor explains.
IEEE Smart Village, supported by IEEE societies and the IEEE Foundation, backs projects that bring electricity and economic opportunities to remote areas. “It’s not just about money,” Numfor says. “We share ideas, we get advice, and we have made friends. Entrepreneurship is lonely, but with the Smart Village community, it is different.”
Background: From Tinkerer to Tech Entrepreneur
Numfor’s first experience with reliable electricity came in 2001 after moving in with a missionary family in Allat. They used solar panels to power their home—an unimaginable luxury for a boy from Mbem. “I could watch TV, eat ice cream, and turn on lights. It made me wish my brothers in Mbem had the same opportunity,” he says.
His curiosity turned to engineering when a motion-sensor solar light broke. “My missionary family told me to play with it like a toy. I replaced the dead battery with a motorcycle battery and brought the power back for the night,” Numfor laughs. That tinkering sparked a lifelong mission.
Supported by his missionary parents, he studied technology independently—since Cameroon’s universities then offered no solar energy programs. He later founded REI Cameroon to bring affordable, sustainable electricity to rural communities across the country.
What This Means: A Blueprint for Off-Grid Energy Access
The partnership between IEEE Smart Village and REI Cameroon proves that community-driven solar minigrids can be financially sustainable. The open-source metering model reduces costs and builds trust, making it scalable to other off-grid regions.
“This isn’t just about lighting homes,” Numfor emphasizes. “Electricity enables education, health care, and small businesses. It transforms entire communities.” With IEEE Smart Village’s ongoing support, REI Cameroon plans to expand to dozens more villages, potentially reaching thousands of new households.
For the children of Mbem—and those in similar villages—the era of “bush lamps” and kerosene hazards is ending. Solar power is igniting a new dawn in rural Cameroon.
