Millions of Nigerians continue to face unreliable electricity supply, with more than 85 million people lacking consistent access to power. Even for households and businesses connected to the grid, high tariffs, frequent outages, and estimated billing remain persistent challenges, affecting daily life and business operations.
To address these issues, Lagos-based clean energy company WiSolar has introduced a “Single Energy Wallet”, a unified electricity platform that combines solar generation, battery storage, and grid electricity into one managed service. The system allows users to access electricity through a single digital wallet while charges are deducted in real time based on actual consumption.
WiSolar said the platform removes the need for manual switching between power sources, eliminates multiple electricity bills, and replaces estimated billing with pay-per-kilowatt-hour charging that reflects actual energy use. Solar power is prioritised as the primary source, with grid electricity automatically taking over when solar output drops due to night-time, weather conditions, or maintenance. Once solar generation resumes, the system switches back seamlessly.
According to Founder and CEO of WiSolar, Tonye Irims, the system is designed to maintain continuous electricity supply while removing operational complexity from users. “Homes and businesses connected to the platform do not control switching between energy sources. Instead, the system balances supply automatically to maintain uptime.”
Pricing under the wallet is linked directly to the energy source, with solar power billed at a lower rate and grid electricity at a higher rate. The system automatically consumes solar energy first and draws on grid power only when necessary. WiSolar said this allows customers to use lower-carbon energy by default while managing costs without making active decisions.
The company illustrated the system’s operation: with a wallet balance of N10,000, a solar rate of N190 per kilowatt-hour, and a grid rate of N225 per kilowatt-hour, deductions occur automatically as energy is consumed. Solar energy is applied first, with grid electricity covering any shortfall. WiSolar said this prevents what customers often describe as “bill shock” by making spending visible at all times.
At the centre of the system is a single wallet for all electricity use. There are no subscriptions, and customers are not issued estimated bills. Charges apply only to actual consumption, billed instantly.
Irims said the platform reflects a shift in electricity delivery, treating power as a managed digital service rather than a fragmented utility experience. “You don’t manage the energy. WiSolar does.”
He added that customers can access the wallet through the mobile application, which enables real-time balance tracking, monitoring of solar and grid consumption, battery performance, and top-ups.
