One Nigerian village without a grid enjoys electricity every night. Another, officially connected to the national grid, does not.
It is a paradox that would have been almost inconceivable a generation ago. Yet as dusk settles across rural Nigeria, it is becoming increasingly common. In one community, children complete their homework beneath the steady glow of LED lights powered by a modest solar home system. A tailor runs an electric sewing machine long after sunset. A small shopkeeper keeps drinks cold and mobile phones charging. A few kilometres away, households connected to the national grid wait in darkness, hoping electricity will return before morning.
For decades, electrification was measured by a simple metric: how many kilometres of transmission line had been built and how many homes had been connected to the grid. Governments planned around it. Development finance institutions invested in it. Utilities were judged by it. That assumption shaped more than infrastructure. It shaped how the world understood development itself.
Today, that assumption is quietly breaking down.
The most consequential electrification story of this decade is not the expansion of national grids. It is the emergence of decentralized energy systems capable of delivering reliable electricity to places where conventional grids cannot do so economically, or sometimes, reliably. Across Africa, off-grid solar, mini-grids and distributed energy systems are not merely compensating for weak utilities. They are redefining what electrification means.
Nigeria’s remarkable growth in off-grid solar adoption is often presented as another symptom of a struggling electricity sector. That interpretation is understandable, but incomplete. What we are witnessing is not simply a response to grid failure. It is the early architecture of a different electricity future.
The world continues to debate generation capacity, transmission expansion and utility reform. Those conversations remain important. Yet they overlook a more profound transition already unfolding across emerging markets. The future of electrification may not depend on building larger grids alone. It may depend on building smarter systems capable of delivering electricity wherever people live, work and create value.
That distinction reveals what I describe as “The Missing Middle of Electrification”.
More than a century of electricity planning has conditioned us to believe that electrification is fundamentally an engineering challenge. Build more power plants. Extend more transmission lines. Connect more customers.
History suggests otherwise.
Electrification has never been purely an engineering problem. It has always been a systems problem. Technology generates electricity. Systems deliver it.
This difference may appear subtle, but it has become one of the defining questions of the global energy transition.
For much of the twentieth century, centralized electricity systems transformed industrial economies. Large power stations generated electricity, transmission networks carried it across vast distances, while distribution companies delivered power to consumers. It was an extraordinarily successful model for countries whose population density, institutional capacity and economic structures made nationwide grids commercially viable.
The twenty-first century presents different realities.
Rapid urbanization, dispersed rural settlements, climate pressures, digital technologies, declining renewable energy costs and changing consumer expectations have fundamentally altered the economics of electricity delivery. Extending conventional grids into every community is no longer the only path to universal energy access. In many places, it is no longer the most efficient one.
Around the world, distributed energy is increasingly becoming a permanent component of modern electricity systems rather than a temporary substitute for them. Nowhere is this transformation more visible than in Africa.
The continent has become the global epicentre of off-grid solar deployment, accounting for the overwhelming majority of global off-grid solar sales. Nigeria’s rapidly expanding market reflects growing investor confidence, technological maturity and increasing consumer acceptance of decentralized energy solutions.
These numbers deserve attention. But their true significance extends far beyond market growth. They signal the beginning of a structural shift in how electricity reaches people.
Much of today’s energy debate remains preoccupied with generation. Governments announce new power plants. Utilities celebrate additional megawatts. Investors evaluate installed capacity. Yet millions of solar panels already exist. Millions of batteries have already been manufactured. The technologies required for decentralized electrification are no longer experimental.
Despite this, hundreds of millions of people continue to live without reliable electricity. If technology alone were sufficient, energy poverty would already be in decline everywhere.
Clearly, something else is missing.
Between electricity generation and meaningful energy access lies an ecosystem that receives remarkably little attention. It determines whether families can afford a solar system, whether equipment reaches remote communities, whether trained technicians are available to install and maintain it, whether digital payment systems make ownership possible, and whether projects become sufficiently aggregated to attract institutional investment.
This ecosystem, not the solar panel itself is where electrification succeeds or fails.
I describe this ecosystem as “the Missing Middle of Electrification”.
This can better be understood as three interconnected layers.
The first layer is technology: solar panels, batteries, inverters, smart meters and mini-grids.
The second layer is physical infrastructure: transmission lines, distribution networks and grid interconnections.
The third, and least understood is, the Missing Middle itself: consumer finance, pay-as-you-go platforms, local installers, maintenance ecosystems, distribution channels, project aggregation, regulatory certainty, digital payments and concessional finance structures.
Most policy debates focus on the first two layers.
The future of electrification will be determined by the third.
Buying thousands of solar panels without building the ecosystem around them is like purchasing an entire fleet of aircraft without airports, maintenance crews or air traffic control. The technology exists, but the system that enables it to function does not.
The lesson is straightforward.
Solar panels do not create electrification. Systems create electrification.
Nigeria offers perhaps the clearest window into this new reality.
Viewed through the traditional lens, its electricity sector appears to be defined by persistent supply constraints, ageing infrastructure and one of the world’s largest unelectrified populations. Yet those same conditions have inadvertently transformed the country into one of the most important laboratories for the future of electrification.
Few markets combine such a large population, rapidly growing electricity demand, a vibrant entrepreneurial ecosystem, expanding digital payment infrastructure and an increasingly sophisticated off-grid energy industry. These characteristics make Nigeria more than a national case study. They make it a high-frequency signal of where global electricity systems are heading.
Across the country, innovation is no longer confined to the engineering of solar technologies. It is emerging in business models.
Pay-as-you-go financing is making electricity affordable for households previously excluded from formal energy markets. Mini-grid developers are demonstrating that communities once considered commercially unviable can become bankable when technology is combined with innovative financing and community engagement. Local installers are creating employment while ensuring systems remain operational long after installation. Digital payment platforms are reducing transaction costs, improving collection efficiency and expanding access to consumers previously regarded as too risky to serve.
These innovations rarely dominate international energy conferences. Yet they are solving problems that additional generation capacity alone cannot.
The lesson extends well beyond Nigeria.
The economics of electrification are changing.
For decades, success was measured by the cost of generating electricity and the capital required to expand transmission infrastructure. Tomorrow’s electricity systems will increasingly be judged by different metrics: the cost of connecting the last customer, the affordability of energy services, the resilience of decentralized networks, the speed of deployment and the ability to attract long-term private capital into underserved markets.
In other words, the competitive advantage is shifting from infrastructure alone to ecosystem design. This distinction has profound implications for governments, utilities and development finance institutions.
The question is no longer whether decentralized energy should complement national grids. That debate is rapidly becoming obsolete. The more important question is how national electricity systems should integrate centralized and decentralized infrastructure into a coherent, resilient and financially sustainable energy architecture.
This also requires a fundamental shift in how utilities define success.
Should utilities continue measuring performance primarily by kilometres of transmission lines constructed and customers formally connected to the grid? Or should success be measured by something more meaningful: the number of households, schools, clinics and businesses receiving reliable, affordable and productive electricity every day?
The answers to these questions will shape investment priorities for decades. They will also determine where development finance delivers its greatest impact.
For development finance institutions, this represents an opportunity to rethink the architecture of energy investment itself. Concessional finance can reduce the cost of capital for mini-grid developers operating in underserved communities. Blended finance structures can mobilize significantly larger volumes of private investment by absorbing early-stage risks. Carbon markets can improve project economics while supporting national climate commitments. Project aggregation can create investment portfolios large enough to attract pension funds and institutional investors that would otherwise overlook smaller distributed energy projects.
Equally important is investment in local capability.
Financing technicians, distribution networks, maintenance ecosystems, digital payment platforms and local manufacturing capacity may ultimately produce greater long-term development outcomes than financing hardware alone. This is where the Missing Middle becomes commercially significant.
Too often, investment focuses on visible assets while overlooking the systems that determine whether those assets perform over time. Solar panels are visible. Transmission towers are visible. Power stations are visible.
The institutions, financing mechanisms, distribution systems and local capabilities that sustain them are far less visible. Yet these invisible systems often determine whether infrastructure succeeds or fails.
Across each article in “The Energy Transition’s Missing Middle” series, the same pattern continues to emerge. Whether examining electricity grids, gas-to-power infrastructure or decentralized electrification, the fundamental constraint is rarely technological innovation.
The technologies already exist. The capital increasingly exists. The policy ambitions certainly exist.
What remains insufficiently developed is the institutional, commercial and financial architecture that connects these ingredients into functioning systems capable of delivering impact at scale.
That is the Missing Middle. It is not a technology gap. It is a systems gap.
Africa’s off-grid revolution therefore deserves to be understood as something far larger than a solar success story. It represents a fundamental rethinking of how electricity can be delivered in the twenty-first century. Rather than replicating the centralized models of the past, African markets are demonstrating how distributed infrastructure, digital finance, entrepreneurial innovation and locally embedded delivery ecosystems can expand access more rapidly and often more economically than conventional approaches alone.
History may ultimately remember this decade not as the moment Africa embraced solar power, but as the moment it redefined what electrification actually means. The next generation of energy leaders will not be distinguished simply by the number of megawatts they build. They will be distinguished by their ability to design systems that transform electricity into economic opportunity, social resilience and inclusive development.
Because the future of electrification may not arrive through another transmission line stretching across the landscape. It may arrive on the back of a motorcycle carrying a solar kit to a village the grid was never designed to reach.
The story is not solar. The story is not the grid. The story is the Missing Middle that connects technology to people, infrastructure to opportunity, and investment to lasting development.
That is where the future of electrification will be won or lost.
The world is not struggling to invent solutions. It is struggling to build the systems that allow solutions to work at scale. That is the Energy Transition’s Missing Middle.
