In Abeokuta, Ogun State, the Olowu of Owu Kingdom, Oba Professor Saka Adelola Matemilola, has transformed his palace into a working demonstration of decentralized renewable power and he intends to share the surplus with his community. The palace currently runs on an operational 50 kVA solar installation that will be expanded into a 120 kVA system. Once the full build is complete, the surplus capacity is expected to light streets, power health centres, and keep public boreholes running across the kingdom.
This energy upgrade is paired with an equally inventive social-innovation project: a 3D-printed, serialized “cowry” token system that will function like a cloud-verified gift card to guarantee school-feeding payments reach children directly. The Olowu plans to roll the cowry scheme out to more than 5,000 schoolchildren when schools resume in September and expand the tokens into a local retail payment option by December. Together, the solar system and the token network aim to reduce carbon emissions, cut costs from unreliable grid supply, and close leakages in welfare delivery.
What’s Actually Installed and How It Will Be Used
The palace’s first phase, roughly 50 kVA, already powers offices, guest rooms, and palace services. Typical palace load averages about 25–30 kVA, leaving meaningful excess capacity to charge batteries and feed public assets at night.
The full 120 kVA system, expected to be completed in the coming months, will allow the Olowu’s team to run street lighting, power a nearby health centre, and electrify several public boreholes that currently depend on unreliable mains or diesel generators. Local stakeholders describe the project as both an environmental choice and a pragmatic hedge against frequent grid outages.
Dr. Akintoye Akindele, an Owu indigene who has been involved in the project, explains that predictable daytime solar generation will allow batteries to store enough energy to power essential services at night. Micro-distribution networks will route electricity to community priorities schools, water facilities, clinics, and markets under the oversight of local leaders. The palace’s approach blends on-site generation, battery storage, and targeted distribution rather than attempting a full grid replacement.
Why This Matters Now: National Context
Olowu’s initiative comes against a backdrop of persistent instability in Nigeria’s national grid. In 2024, the grid suffered multiple full or partial collapses, and outages remain frequent in 2025. These power failures have disrupted businesses, homes, and essential services across the country. Causes include ageing transmission infrastructure, vandalism, and fuel shortages all of which make decentralized solar systems and mini-grids an increasingly attractive complement to the central grid.
International development partners and the Nigerian government have been pushing distributed renewable solutions at scale. Programs supported by the World Bank and Nigeria’s own mini-grid expansion plans aim to increase access through private-sector-led solar home systems and community mini-grids, targeting millions of new connections. These efforts show how localized projects when financially and technically viable can multiply rapidly, especially in areas where the national grid remains unreliable.

The Social-Technology Twist: Cowries Meet Cloud Verification
What sets the Olowu’s project apart is the pairing of renewable energy with social accountability. The 3D-printed cowry tokens are cultural symbols redesigned as serialized access tools. Each token is linked to a child in a secure cloud database. When a child redeems a meal at an approved vendor, the vendor logs the serial number, and the system records the consumption in real-time.
This method aims to eliminate the leakages that plague school-feeding programs, where funds or supplies sometimes fail to reach intended beneficiaries. The cowry also carries cultural significance, increasing local acceptance. The plan to expand cowries into a local gift-card system by December could help create a small-scale, self-sustaining community economy.
If executed successfully, the palace-to-community model could deliver three quick wins:
- Cleaner Power: Reduced use of diesel generators will lower carbon emissions and improve air quality.
- Reliable Services: Street lighting, water pumping, and healthcare facilities will have consistent electricity.
- Stronger Social Accountability: Welfare programs will be auditable, reducing corruption and mismanagement.
Beyond immediate benefits, leadership from a respected traditional ruler can encourage acceptance of new technologies. This cultural legitimacy can help overcome skepticism, attract local business participation, and encourage donors to support the project.
Risks and Scaling Challenges
Despite its promise, the initiative faces potential hurdles. Mini-grid and community energy projects in Nigeria often struggle with financing, unclear regulations, maintenance issues, and security risks such as vandalism and equipment theft.
Sustaining the project will require a reliable operations and maintenance plan, clear agreements on who manages the power distribution, and consistent revenue streams to keep batteries and inverters in good condition. Scaling the model to other communities would also require alignment with national electrification plans to prevent overlap or waste.
International experience shows that expanding from pilot projects to full community coverage typically requires blended finance models, where public and private funds combine to make the investment viable.

Observers will be watching for several key developments:
- Completion of the 120 kVA installation.
- Successful and transparent rollout of the cowry system in September.
- Vendor participation in the token network.
- Evidence that surplus solar power is indeed reaching public services as promised.
If the Olowu’s team can demonstrate cost-effectiveness, transparency, and resilience against theft or mismanagement, the project could serve as a model for other traditional institutions and local governments across Nigeria.
