British International Investment (BII), the United Kingdom’s development finance institution, has provided $7 million in financing to Okra Solar to support advance equipment purchases for decentralised electricity projects, in a move aimed at accelerating new connections in Nigeria, where approximately 87 million people still lack access to electricity.
The facility is expected to finance equipment for about 150,000 new electricity connections, potentially reaching 750,000 people, according to BII’s project summary. By enabling the company to purchase equipment before securing individual project contracts, the financing is intended to reduce procurement delays and improve the speed at which decentralised power systems can be deployed.
The investment addresses a persistent challenge facing off-grid energy companies: the time and capital required to maintain equipment inventory. Until now, Okra Solar typically ordered equipment only after reaching agreements with project developers, purchasing in batches of a few thousand units. This approach limited the company’s ability to respond quickly when new projects were secured, particularly where equipment had to be sourced and transported internationally.
With the new financing, Okra Solar will be able to procure larger quantities in advance and hold equipment ready for deployment once contracts are signed. Chief Executive Officer Afnan Hannan said the arrangement would allow equipment to reach Nigeria in less than one-third of the time previously required, potentially shortening the period between project agreements and electricity connections.
The financing therefore targets more than the cost of installing renewable energy systems. It addresses a supply-chain constraint that can slow the expansion of off-grid electricity services, even when demand and project opportunities are present. For decentralised energy companies operating in markets with substantial electricity access gaps, the ability to secure inventory ahead of demand can influence project delivery schedules, operating capacity and the number of households reached.
Okra Solar supplies solar mesh grid technology, which combines solar generation, battery storage and smart devices that enable neighbouring homes and businesses to share electricity. Unlike conventional systems designed around a single household or a centralised mini-grid serving a defined area, mesh grids allow connected users to distribute available power across a network of nearby customers.
BII describes the technology as complementary to individual solar home systems and conventional mini-grids, particularly in smaller and geographically dispersed communities. Such settlements can be difficult or expensive to serve through traditional grid infrastructure, while the economics of larger mini-grid developments may not always be viable where households and businesses are spread over wide areas.
Nigeria’s electricity access deficit provides a substantial potential market for these alternatives. With approximately 87 million people without electricity, the country faces the challenge of extending reliable power to underserved communities while supporting economic activity in areas where grid expansion remains limited. Decentralised renewable energy systems offer one route to addressing this gap, although their contribution will depend on affordability, equipment reliability, financing conditions and the ability of operators to sustain services after installation.
The BII facility comes as Nigeria consolidates its position as a major destination for investment in off-grid solar. According to the 2025 Investment Data Report published by GOGLA, with support from the World Bank‘s Energy Sector Management Assistance Program (ESMAP), Nigeria attracted $114 million of the $315 million invested globally in off-grid solar companies during 2025. This represented the largest national share of the reported global investment total.
The figures point to the growing importance of Nigeria within the decentralised energy market. However, investment raised by companies does not automatically translate into new electricity connections. The conversion of capital into functioning systems depends on project execution, distribution networks, customer financing and the capacity of energy businesses to operate commercially in communities where purchasing power may be constrained.
For investors and development finance institutions, this creates a case for financing interventions that address operational bottlenecks alongside the cost of infrastructure itself. Equipment procurement is one such constraint. Companies that can secure inventory in advance may be better positioned to respond to project demand, reduce delivery uncertainty and manage the time between investment commitments and actual deployment.
The scale of the anticipated connections under the Okra Solar facility also raises questions about the long-term performance of decentralised systems. Reaching 150,000 new connections will be an important measure of deployment, but the development value of the investment will ultimately depend on whether households and businesses receive reliable electricity over time. Maintenance arrangements, battery replacement, tariffs, customer affordability and the financial sustainability of operators will all influence whether new connections deliver lasting benefits.
For Nigeria, the expansion of decentralised renewable energy could support households, small enterprises and community services that face the economic costs of unreliable or unavailable electricity. Access to dependable power can enable businesses to extend operating hours, support productive uses of energy and reduce dependence on diesel generators. Yet these benefits are not automatic; they require systems that are appropriately sized, maintained and affordable for the communities they serve.
The $7 million facility illustrates how development finance can support the less visible parts of energy infrastructure delivery, including inventory financing and supply-chain capacity. As Nigeria attracts a significant share of global off-grid solar investment, the next test will be whether financing commitments and technology deployment translate into dependable electricity access at scale.
The proposed 150,000 connections offer a measurable target. Their wider significance, however, will be determined by the quality, affordability and continuity of the electricity services delivered to the people and businesses they are intended to reach.
