The Infrastructure of Abundance

Chapter 1

It's all sunlight anyway

Walk down almost any street in Lagos after dark and you'll hear the country's real power system before you see it. It's a low, uneven hum coming from behind gates, under staircases and outside shops: millions of small engines, each burning fuel to make a few kilowatts for the people next to it.

I want to start with a simple claim, because the rest of this essay depends on it. The diesel in those generators is sunlight.

Hundreds of millions of years ago, plankton and algae in shallow seas captured sunlight through photosynthesis and turned it into carbon-rich tissue. When they died they sank, were buried, and over geological time heat and pressure cooked them into crude oil. When we pump that oil out of the Niger Delta, refine it into diesel, truck it to a filling station and pour it into a generator, we are releasing sunlight that fell on the Earth before the dinosaurs.

Look at it that way and almost the whole energy system turns out to be sunlight, harvested in different ways.

• Gas is the same buried organic matter as oil, taken deeper and hotter. Past a certain temperature, the long hydrocarbon molecules in oil crack apart into short ones, ending as methane. Much of Nigeria's gas sits alongside its oil for exactly this reason.
• Coal is the land-based version: swamp forests that captured sunlight, died, and were buried and compressed before they could rot.
• Wind is sunlight: the sun heats the Earth unevenly, and air moves to even it out.
• Hydropower is sunlight: the sun evaporates water, it falls as rain on high ground, and we catch it on its way back down at Kainji, Jebba and Shiroro.
• Firewood and charcoal are sunlight stored for a few years rather than a few hundred million.

There are only three real exceptions. Geothermal energy is heat left over from the Earth's formation, topped up by radioactive decay deep underground. Tidal energy comes from the moon's gravity pulling on the oceans. Nuclear energy is released by splitting atoms like uranium.

A useful test is to ask what would happen if the sun switched off. Within weeks, the wind would die as temperature differences evened out, the rain would stop, and plants would stop growing. We would still have whatever oil and gas was already underground, but that's a savings account with no more deposits. Geothermal, tides and nuclear would carry on. And even those exceptions trace back to stars: uranium was forged in exploding stars long before our sun formed. Nearly all the energy we use is starlight. Most of it is our own star's.

So the real question, behind what most people would call "solar and renewables versus oil and gas," is which way of harvesting sunlight, at what cost, with how much complication, and with what side effects.

On those three measures, the old answer was clear. Stored sunlight (oil and gas) won. Oil is extraordinarily dense: a litre of diesel holds about 10 kWh (kilowatt-hours) of energy, and you can carry it in a jerrycan, keep it for months and burn it whenever you like. Fresh sunlight is the opposite. It's dilute, it only arrives during the day, and for most of the twentieth century turning it into electricity was absurdly expensive. Solar panels powered satellites, calculators and little else.

But stored sunlight has always come with a long and fragile chain. Somebody has to find the oil, drill it, ship it, refine it, import it (for most of Nigeria's history, we exported crude and imported the refined product back), store it, truck it across bad roads, sell it at a pump, and carry it home. At the end of all that, a small generator turns perhaps a fifth to a third of the fuel's energy into electricity and throws the rest away as heat, noise and fumes. The side effects are real: carbon monoxide in poorly ventilated rooms, tanker explosions, fuel queues, smog, and an economy whose cost of production rises and falls with a price set in London and Riyadh.

Here's how the main options compare for electricity in Nigeria today. Each cost figure is worked through later in the essay.

(Firewood and charcoal belong in the family tree but not the table: they cook food rather than make electricity.)

What changed is that the last row stopped being a niche.

Two things happened. First, solar panels became manufactured goods produced at enormous scale, and manufactured goods follow learning curves: every time cumulative production doubles, the cost falls by a roughly fixed percentage. For solar modules that has been about 20% per doubling for decades. Oil gets no such curve: it's extracted, and the cheapest barrels get pumped first. Over time, the thing you make gets cheaper and the thing you dig up doesn't.

Second, batteries arrived. The great weakness of fresh sunlight was that it couldn't be stored, so it couldn't compete with a fuel you could burn at 9pm. LFP (lithium iron phosphate) batteries, pushed down their own learning curve by electric vehicles, fixed that. A panel plus a battery is, functionally, a machine that stores sunlight for hours instead of millions of years.

This is the pattern Clayton Christensen described in The Innovator's Dilemma. The new technology starts out worse than the incumbent on the measures that matter to mainstream customers, so it serves the fringes: satellites, rural lanterns, telecom masts in the bush. The incumbents ignore it. It keeps improving at a pace the incumbent can't match, and one day it's simply better for most people. In Nigeria, I think that day has already come for anyone paying for diesel or petrol to make electricity. The rest of this essay is about why, how big this gets, and what it could make possible.

Nigeria sits in one of the sunniest belts on Earth. For fifty years we have sold our stored sunlight abroad and bought it back refined, while the fresh stuff fell on our roofs for free.

Chapter 2

The generator nation

Most discussions of Nigerian power start with the grid. I think that's the wrong place to start, because for most people who pay for electricity, the grid isn't the thing they're trying to replace. To see why, it helps to build the picture from the bottom up, starting with litres of fuel.

Start with total litres. The NMDPRA (Nigerian Midstream and Downstream Petroleum Regulatory Authority) publishes monthly figures. Its 2026 daily benchmarks are 50 million litres per day for petrol and 14 million for diesel, and actual truck-outs move around those numbers: in December 2025, petrol consumption was 63.7 million litres a day and diesel 16.4 million; in March 2026, diesel consumption fell from 20.3 to 14.5 million litres a day; and in August 2026, petrol truck-outs dropped to 41.5 million litres a day. Call it roughly 45–50 million litres of petrol and 15 million litres of diesel a day. Over a year, that's about 17–18 billion litres of petrol and 5.5 billion litres of diesel.

At late-2026 pump prices of around ₦1,400 a litre for petrol and ₦2,000 for diesel, Nigerians spend about ₦23–25 trillion a year on petrol and ₦11 trillion on diesel: roughly ₦35 trillion, or about $26 billion, on two liquid fuels. That's somewhere around 8–10% of GDP.

Checking the numbers from the other end

Truck-out data measures what leaves depots. We can cross-check it against what comes in: Dangote's domestic deliveries plus imports. August 2026 is the cleanest recent month (NMDPRA factsheet, imports, Dangote split):

Supply runs ahead of truck-outs in August because stocks were being rebuilt. Over the year, the two methods agree within 10–20%: petrol has ranged from about 41 to 60 million litres a day in 2026, and diesel from about 12 to 20 million. My working figures sit in the middle of both.

One discrepancy is worth flagging. Dangote's own H1 2026 report puts its domestic supply at around 50 million litres of petrol and some 25 million litres of diesel a day. The regulator's monthly figures are lower: in July, for example, NMDPRA recorded 25.8 million litres a day of Dangote petrol going to the domestic market. I use the regulator's numbers throughout, because they're published monthly and line up with truck-out data.

From litres to kilowatt-hours

Split by end use. Diesel does two jobs in Nigeria: it moves heavy things (trucks, buses, construction equipment, boats) and it makes electricity (generators at factories, banks, hospitals, hotels, estates, malls, telecom towers and wealthier homes). My view, from sitting with customers and watching where the tankers go, is that most of Nigeria's diesel ends up in generators rather than trucks. There's no official split, so I'll assume 60% goes to power generation and invite anyone with better data to correct me. That's about 3.3 billion litres a year.

Petrol is mostly transport: cars, okadas, kekes and buses. But Nigeria is unusual in that a meaningful share of petrol is burned in small generators, the 1–3 kVA (kilovolt-ampere) machines that power a fridge, a fan and a TV in millions of households and small shops. I'll assume a quarter of petrol goes to generators: about 4.5 billion litres a year.

Convert litres to kilowatt-hours. This is where the number most people quote, ₦630/kWh, turns out to be the optimistic case.

A diesel generator's efficiency depends heavily on how hard it's working. Run near its rated output, it might produce 3.2–3.4 kWh per litre. Run at a quarter of its rating, it produces far less, because a big engine burns a lot of fuel just turning over. And in Nigeria, generators are routinely oversized: a 60 kVA set bought for the occasional peak spends most nights powering a few air conditioners and lights at a fraction of its capacity.

So ₦630/kWh is roughly what a well-matched generator achieves. The average Nigerian generator, oversized and lightly loaded, probably costs more. Then add what fuel cost leaves out: oil changes and servicing every few hundred hours, filters, overhauls, and the generator itself wearing out. On a typical commercial set, that adds something like ₦80–100 per kWh, taking the all-in cost to around ₦720/kWh. Small petrol generators are worse again: running at partial load, they produce perhaps 1.5–2 kWh per litre, which puts fuel alone at ₦700–900 per kWh.

Putting the national picture together, using the conservative per-litre figures:

If the fleet runs less efficiently than assumed, the cost per kWh is higher and the electricity produced is lower. Either way, the ₦13 trillion is real money already being spent.

That 19 TWh is also less than the electricity Nigerians actually want. It's what they can afford to generate. Households and businesses ration generator hours: on in the evening, or during working hours, and the rest of the time they go without. Rationing is already baked into the litres; it means the true demand is larger, a point I come back to in chapter 8.

For comparison, the national grid sends out somewhere around 35–40 TWh a year, and a large share of that is lost before it's billed. In capacity terms, the gap is even more striking: Wood Mackenzie research from 2022 estimated Nigeria had 28 GW of diesel generator capacity, one of 17 countries where generator capacity exceeded on-grid power plant capacity. What Nigeria actually has is a vast, private, fuel-burning power system with a grid attached.

The real incumbent

When people say solar in Nigeria "competes with the grid," they usually compare it to a Band A tariff of around ₦210–225/kWh. That's the wrong comparison. Band A is the best grid supply in the country, it's only available to some customers, and even they run generators when it goes off. The real incumbent, the thing people are actually paying for at the margin, is self-generation at ₦630–900/kWh.

How unusual is that? It helps to compare what solar is up against in other countries. Two things decide how valuable a solar panel is: the price of the power it replaces, and how much sun it gets.

Germany and the UK have expensive grids but weak sun. India has strong sun but cheap grid power. Pakistan's boom happened at roughly a third to a half of Nigeria's value per panel. Nigeria is unusual in having both: some of the most expensive incumbent electricity on Earth and some of the strongest sunshine. A kilowatt of panels here is worth roughly two to three times what it's worth in Britain or Pakistan.

That changes the economics completely. Nobody has to be persuaded that electricity is worth paying for. The millions of generators running every night are the proof.

Prices over time. This matters more because fuel has become far more expensive in a short time. Diesel cost roughly ₦220–250 a litre in 2019, crossed ₦800 during the 2022 price spike, and has sat at ₦1,800–2,000 for most of 2026. Petrol was held at around ₦145–185 by subsidy until May 2023; it's now ₦1,400 or more. In five years, the fuel cost of a generator kWh has risen roughly eightfold in naira.

And people respond to price. In the first half of 2026, according to marketers' data, average petrol consumption fell from about 60 million litres a day in January to roughly 46 million in May, and diesel consumption dropped 17.5% over the same period. Some of that is people simply doing without. Some of it is people buying panels.

Pakistan is the parallel

Pakistan in the early 2020s looked a lot like Nigeria today: a population of similar size, a strained grid, and a sudden supply of cheap Chinese panels. The trigger there was the grid price: grid electricity prices rose by roughly 155% between 2021 and 2024. The response was extraordinary. Pakistan imported 17 GW of panels in 2024 alone, double the previous year, and cumulative imports reached about 50 GW by August 2025, roughly equal to the country's entire grid capacity. Grid demand fell: a 10.4% reduction over a single year.

Nigeria's version has started. In the 12 months to June 2025, Nigeria overtook Egypt to become Africa's second-largest panel importer, at 1,721 MW, and it imported 2.9 million panels worth more than ₦435 billion over 2025, with imports holding firm across all four quarters.

So Pakistan built 50 GW at a fraction of the value per panel that Nigeria offers. The economic pull here is larger. What Nigeria lacks is the finance and installation capacity to respond at Pakistan's speed. That's the gap this essay is about.

Chapter 3

The crossover

The case for solar in Nigeria rests on two price curves heading in opposite directions. One is fuel. The other is hardware.

What hardware costs today

Here are numbers from Lagos in late 2026, at four levels of scale. We import our own panels, one container at a time, so I can show how each component's cost builds up from the factory gate to a Lagos warehouse:

The three components behave very differently. Batteries already sell close to landed cost, so there's little to gain from importing them at small scale. Panels carry a modest markup. Inverters carry the most: a mid-market unit sells for up to nearly double its landed cost, and a premium brand for close to four times. Freight, clearing and haulage are also partly fixed, so an importer bringing in many containers spreads them more thinly and negotiates lower factory prices.

For a standard 10 kWp (kilowatt-peak), 10–12 kVA, 15 kWh system for a large home or small business, that gives four price levels:

Competitor quotes I've seen for this spec sit at ₦6–6.9 million. In the rest of this essay I use ₦7 million as the conservative retail case and ₦4.5 million as the scale case: scale takes more than a third off.

These are global commodity prices that a decade ago would have been unthinkable. Module prices fell roughly 90% over the 2010s. Battery pack prices fell by a similar amount. In Nigeria, Ember estimates a 420W panel retails for about $60 and produces around 550 kWh a year.

The naira trap. A common objection is that devaluation kills solar, because panels and batteries are priced in dollars. But diesel and petrol are also priced in dollars. Nigeria imports refined product or refines crude that trades at world prices. Devaluation pushes up both sides of the comparison at roughly the same rate. What actually decides the race is what happens in dollar terms, and there the story is one-sided: since 2019, diesel at the Nigerian pump has roughly doubled in dollars, while panels have roughly halved. The ratio between them has moved by a factor of four or five. Subsidy removal in 2023 then pulled petrol into the same trend.

What a kilowatt-hour of solar costs

In Lagos, 10 kWp produces around 13,000–14,000 kWh a year; in the north, more. Not all of it gets used, because loads don't perfectly match the sun. A conservative planning figure is 8,000 kWh of useful electricity a year; well-matched systems at heavy-use sites deliver 9,000 or more.

• Over a 15-year life, including maintenance and component replacement: roughly ₦8.5 million for 120,000 kWh, or about ₦70/kWh unfinanced
• Financed at a 25% cost of capital: about ₦240/kWh at retail prices, or about ₦160/kWh at scale

Even the expensive, financed case is a third of what a generator costs.

Payback depends on the grid, and the grid is worse than its labels

The honest answer to "how fast does solar pay back?" is: it depends on how long the generator would otherwise run, and that depends on the grid.

On paper, Band A means at least 20 hours of supply a day and Band B at least 16. In practice, Band A availability swings between roughly 40% and 80% of hours from month to month, and Band B often sees about a third. Real generator hours are far higher than the labels suggest.

"Off-grid" doesn't mean the generator runs all day either. Most households and businesses ration it: on in the evening, or during working hours, and the rest of the time they go without.

So I ran the same ₦7 million system through an hourly simulation covering a year of Lagos sunshine, a typical load of about 33 kWh a day peaking in the evening, and grid outages that vary by band and by month. When the grid is off, the generator covers outages from 6am to midnight. The battery holds a reserve for outages, so solar targets the hours the generator would otherwise run. Generator power is valued at ₦720/kWh all-in, Band A grid at ₦210 and Band B at about ₦65.

Three things stand out.

• Even Band A pays back in under two and a half years. Its reliability is mostly on paper, and the battery covers the hours the grid fails, which is exactly when the generator was costing most.
• For households that ration their generator, solar brings more power as well as savings. A home running its generator only in the evening saves around ₦2.8 million a year, but it also gets roughly 5,500 kWh a year of electricity it previously went without. That's more than it used to buy from the generator. The pitch to that household is "spend the same, get twice the electricity."
• About a quarter to a third of the panels' output goes unused. It's produced at midday when the battery is already full. Today that's wasted. In a networked future, it's power a neighbour could buy (chapter 8).

These paybacks are faster than Ember's estimate of 18–36 months for full systems for two reasons. The model values generator power at ₦720 including maintenance, and it assumes the system is well matched to the load. A badly sized system will do worse, which is why design matters. The input that matters most, and that nobody publishes properly, is real grid availability by band, feeder and month. That's data I want to collect and publish.

How much battery?

The battery is what turns solar into a generator replacement. Here is the same 10 kWp array with different battery sizes:

At a heavy-use site, panels without a battery deliver about 5,200 useful kWh a year; with 15 kWh of battery, about 9,400. The battery nearly doubles what the panels are worth. The sweet spot is about 1.5–2 kWh of battery per kWp of panels. Beyond that, each extra kWh of battery covers rarer and rarer outages, and payback starts to lengthen.

When did the lines cross?

For anyone running a generator, I'd put it around 2022–23: the diesel spike and the end of the petrol subsidy, landing just as module prices hit record lows. Before then, solar made sense for the patient and the well-capitalised. After, it was the cheapest power you could buy.

So why isn't everyone on solar already? Because a system that's cheap over its lifetime still has to be paid for on day one. A system that pays back in two years still costs ₦5–7 million upfront, and most households and businesses don't have that sitting idle, especially when naira borrowing costs 25–30%. The barrier is financing.

That's exactly the gap capital is built to fill. If you believe the numbers above, and I've spent the last year and a half watching them hold on real sites, then there's a trade available where everyone wins: an investor pays the upfront cost, the customer pays less than they do today, and the investor still earns a fast return, all else being equal.

The abundance point

Here is the part I think investors have underrated.

A diesel user is a proven customer. They have already shown, with their own money, every day, that they'll pay ₦630 or more for a kWh. You don't have to create demand, educate a market or wait for a regulator. The demand is there and it's being served badly.

So consider the offer an EaaS (Energy-as-a-Service) provider can make to a heavy generator user. "We'll install the system at our own cost. You pay us half what you currently spend on fuel, ₦315 per kWh, for the power you use." The customer saves 50% from day one with no upfront spending. On around 9,000 useful kWh a year, the provider earns about ₦2.8 million on a ₦7 million asset, a payback of about two and a half years. At scale prices, it's under two. That's infrastructure with a long life and an existing, motivated customer.

That's a different category of investment from most energy infrastructure in Nigeria. A gas power plant takes years to build, depends on a gas supply that gets vandalised, sells into a grid that struggles to collect payment, and needs long-dated finance to make the numbers work. A rooftop system takes days to install, depends on nothing but sunlight, and pays back in two to three years selling to someone who already wants to buy.

When something is that much cheaper than what it replaces, it will happen. The open question is how fast capital, installers and supply chains can move.

Chapter 4

The power station is on the roof

Every other power system Nigeria has tried is centralised. Gas comes from the Delta through pipelines that get vandalised. It's burned in power stations owned by one set of companies, sent through transmission lines owned by TCN (Transmission Company of Nigeria), and delivered by DisCos (distribution companies) that struggle with losses, metering and collection. Every link is a failure point, and the system is only as reliable as its weakest one.

The generator was the people's answer: decentralise the generation, but keep the fuel. That traded one long chain for another: crude to refinery (or import terminal), depot, tanker, filling station, jerrycan, generator, mechanic. Every link in that chain is also a failure point, as anyone who has queued for fuel during a scarcity knows.

Solar plus battery cuts the chain to its minimum. The hardware arrives once: panels, inverter, battery. After that, what remains is maintenance: cleaning panels, checking connections, watching battery health, and replacing the inverter once or twice over the system's life. That's real work, and the industry neglects it at its peril, but it comes to a technician's visit every few months. A generator needs a tanker every few days. Solar's fuel arrives every morning without a queue or a price.

That's decentralisation (generation where the consumption is) and localisation (very little ongoing dependency on anything outside the building). The knock-on effects are bigger than they first look:

• Fewer tankers. Every litre of generator fuel moves by road. Take billions of litres out of the system and you take a large number of tanker journeys off Nigeria's roads, with fewer accidents, explosions and jams. I suspect solar could take a measurable bite out of Lagos traffic, though I haven't seen anyone quantify it.
• No fuel scarcity. A business on solar doesn't stop when there's a depot strike or a supply disruption.
• Cleaner air and quieter streets. Generator fumes kill people every year through carbon monoxide poisoning, and the background roar of millions of engines is a public health problem we've learned to ignore.
• Foreign exchange. Every kWh made from sunlight is a kWh not made from imported or world-priced fuel. In nine of Africa's top ten solar importers, refined petroleum imports outweigh solar imports by a factor of 30 to 107. Solar is the rare import that reduces the import bill.

What's still hard

It would be dishonest to stop there. The economics are excellent, but several things stand between good economics and a country that runs on sunlight.

Finance. The single biggest barrier is upfront cost. A system that pays back in two years still costs ₦5–7 million on day one, and most households and small businesses don't have it. Naira lending rates are 25–30% or more. Development finance often arrives in dollars, which creates the next problem.

Currency. Hardware is bought in dollars; customers pay in naira. A provider who signs a five-year naira contract and then watches the naira halve has a problem. The fixes exist (tariffs indexed to diesel prices or exchange rates, local-currency finance, partial guarantees) but they add cost and complexity.

Quality and maintenance. Nigeria's solar market is full of undersized inverters, dying lead-acid batteries, fake or mislabelled panels and installers who disappear after payment. Every failed system becomes a story about how "solar doesn't work." The industry needs enforced standards from SON (Standards Organisation of Nigeria), real warranties, trained technicians, and remote monitoring so that faults get caught before customers lose faith.

Design. The flip side of the payback tables in chapter three is that a badly sized system can destroy the economics. Too little battery and the generator keeps running in the evening; too much and the customer pays for capacity they rarely use. Getting sizing right for each site's load, grid pattern and generator habits is a skill, and it's scarce.

Space and scale. A home or a shop can often fit what it needs on its roof. A factory running a 500 kW load usually can't, and a dense multi-storey building certainly can't. Larger users will need ground-mounted arrays, shared systems, or eventually a grid that can carry solar power from where it's generated to where it's used.

Seasons. Output drops in the rainy season and under harmattan dust. Systems have to be sized for the worst months.

The grid's finances. Pakistan shows the danger: when better-off customers cut their grid use, the grid's fixed costs fall on a smaller and poorer customer base, unit prices rise for those left, and more people leave, a cycle known as a utility death spiral. Nigeria needs a grid built to work with distributed solar.

None of these is a reason to doubt the direction, and all of them are work that needs doing.

Chapter 5

Powering production

Cheap electricity matters less as a household bill than as an input to production. The gains from solar look very different depending on who's using it. Going segment by segment:

Homes. By number of systems, households are the biggest market, from wealthy homes running 10–20 kVA generators to families running a petrol "I-better-pass-my-neighbour" set for a few hours each evening. The gains are real: lower bills, quieter nights, no fumes, and for rationing households, far more hours of power. Pay-as-you-go solar home systems have already brought light and phone charging to millions who never had a grid connection. But a home mostly consumes power, so the economic multiplier is limited, except where the home is also a business, which in Nigeria it often is.

SMEs (small and medium enterprises). For a barber, tailor, printer, pharmacy, cold-room operator, welder or restaurant, energy can be one of the largest costs after rent. A hairdresser who cuts her fuel bill in half has, in effect, raised her margin. A cold-room operator who can run 24 hours without diesel can stock more and waste less. The gains here are directly economic, spread across millions of businesses, and they show up as lower prices and more jobs. The challenge is finance at small ticket sizes, which is where lease-to-own and pay-as-you-go structures matter.

C&I (commercial and industrial). Factories, malls, hotels, hospitals, banks, office blocks and residential estates are the largest diesel burners per site and the most creditworthy customers. This is where EaaS fits best: big loads, daytime consumption, proven willingness to pay, and balance sheets that can sign five- to ten-year contracts. They also tend to run the most oversized generators, so their real cost per kWh is often well above ₦630. A manufacturer whose energy cost falls from ₦700 to ₦300 per kWh is more competitive against imports and, in time, in export markets.

Agriculture. This is where I think the biggest untapped gains are. Most Nigerian farming is rain-fed, so the land sits idle for months each year. Solar irrigation pumps make dry-season farming possible across the north without diesel. Solar cold storage cuts the enormous post-harvest losses on tomatoes, peppers and fish. Solar-powered milling, drying and processing let farmers sell finished products instead of raw ones. Each of these turns electricity directly into food and income.

Mini-grids. For communities far from the grid, solar mini-grids run by private developers are often the cheapest route to 24-hour power. Their economics depend on anchor loads: a large daytime consumer such as a mill, a clinic, a telecom tower or a market, whose steady demand makes the system bankable and lets households connect at affordable tariffs. The REA (Rural Electrification Agency) and development partners have built a solid programme here. The next step is scale.

Telecoms. Nigeria has tens of thousands of telecom towers, and many burn diesel around the clock, especially outside the cities. Towers are ideal for solar: constant load, secure sites, operators with balance sheets. Tower companies have been hybridising for years. Finishing the job would remove a large and very visible slice of diesel demand.

Where are the biggest gains? It depends on what you measure. By diesel displaced, C&I and telecoms come first. By economic multiplier, agriculture and SMEs come first, because cheaper power there translates directly into more food, more output and more jobs.

The strategic projects

If I were designing a national programme, these would be my first priorities:

1. Industrial parks and export zones on solar and storage, so that the businesses most exposed to international competition get the cheapest power first.
2. Solar irrigation across the northern states, turning one growing season into two.
3. Cold-chain corridors linking farms to cities with solar-powered storage at each step.
4. Market electrification, putting solar on Nigeria's great markets, where thousands of traders currently run thousands of generators.
5. Hospitals and clinics, where reliable power is a matter of life and death.
6. Tower solarisation, a contained, high-impact programme with willing private partners.

Each of these doubles as an anchor load: once a system serves a market, a clinic or an industrial park, connecting the homes and shops around it becomes cheaper and easier.

Chapter 6

Moving things

So far this essay has been about stationary power: the generator half of Nigeria's fuel bill. The other half is transport, and most of the petrol Nigeria burns moves people and goods.

Two- and three-wheelers first. The fastest change will come from okadas and kekes, for a simple reason: they're commercial vehicles running long hours, so fuel is a huge share of the rider's costs, and the vehicles are cheap enough to electrify now.

A rough comparison: an okada doing 100 km a day burns about 2.5 litres of petrol, or ₦3,500 at ₦1,400 a litre. An electric motorcycle covering the same distance uses about 4 kWh. Even charged at ₦300/kWh, that's ₦1,200. A keke doing 150 km a day might burn 6 litres (₦8,400) against 15 kWh electric (₦4,500). Electric motors also have far fewer moving parts, so maintenance falls too. For a rider who earns a living on the road, that difference is the difference between scraping by and saving.

Battery swapping makes it practical: a rider swaps a depleted battery for a charged one in a couple of minutes at a station, rather than waiting hours to charge. And if those swap stations are themselves powered by solar and storage, the rider's fuel supply has gone from a refinery and a tanker to a panel on a roof down the road. That's the same localisation logic as chapter four, applied to movement.

Buses next. City buses run fixed routes and return to the same depot each night, which makes them easy to charge. Lagos has piloted electric buses on its BRT (bus rapid transit) routes. The federal push towards CNG (compressed natural gas) vehicles is a sensible bridge: it uses Nigerian gas rather than world-priced petrol, and it builds the habit of switching away from liquid fuel. But electric buses charged from solar-plus-storage depots will, I think, win on cost by the early 2030s.

Trucks last. Long-haul freight is the hardest case. Trucks are heavy, travel long distances and need big batteries, and Nigeria lacks charging corridors. I expect trucks to electrify in the late 2030s and 2040s, starting with short, repetitive routes such as port-to-depot, quarry-to-site and urban delivery. For long distances, the better answer is probably rail, which Nigeria should be building anyway.

How much power does transport need? A rough estimate: if about three-quarters of Nigeria's petrol goes to transport, that's around 13 billion litres a year, holding roughly 120 TWh of chemical energy. Combustion engines waste most of that as heat; electric drivetrains are roughly three to four times more efficient. So electrifying today's road transport would need something like 35 TWh of electricity a year, about the same as the entire grid supplies now, and achievable with roughly 25 GW of solar.

That's a big number. It's also a small one next to the destination.

Chapter 7

Electrostate

Everything so far has been about replacing what Nigerians already burn. That's the beachhead. This chapter is about what comes after it.

A petrostate is a country whose economy and politics are organised around selling stored sunlight. Nigeria has been one for half a century, with the paradox of importing much of its own refined fuel for most of that time. An electrostate is something different: a country whose economy runs on cheap electricity it generates at home from sunlight, and which uses that cheap electricity to make things.

The word that matters in that definition is cheap. Solar will spread across Nigeria whatever the government does, because it already beats the generator. But it won't become cheap on its own. A market prices power against the alternative. While the alternative is a ₦720 generator kWh, solar will be sold at half of that, or a little under it, and the gap between that price and the ₦80–150 it actually costs becomes margin. That's a good business, and it leaves power expensive.

So what separates a country that has a lot of solar from an electrostate is intent: a government that treats low-cost energy as the industrial strategy itself. China is the clearest example. It built the world's largest solar manufacturing industry and the world's largest solar fleet, and it treats cheap power as an input to everything else it makes. Most industrial strategies pick winners: this sector gets a tax break, that one gets a tariff wall. Cheap energy lifts every producer at once, from the welder in Aba to the fertiliser plant to the cold room at the market. It may be the only industrial strategy that doesn't require the government to guess which industries will win.

It helps to think of it as a ladder. Each rung is a level of abundance, each needs more deliberate choices than the one below it, and each implies a much bigger fleet of panels and batteries. The capacities line up with the stages in chapter 9.

Cheaper than diesel

The first rung needs almost nothing from government, and it's where Nigeria is now. Commercial capital in Nigeria wants its money back fast. With naira interest rates at 25–30% and real risks around currency, contracts and collection, investors look for paybacks of around two years. That's why EaaS pricing sits at around half of diesel: it's what a two-to-three-year payback requires. The panels are arriving by the million without a national programme, because the arithmetic already works. This rung takes Nigeria from what is probably a gigawatt or two installed today to around 10 GW by 2030, the first stage in chapter 9.

Government's job on this rung is mostly to protect it: no import bans, no new levies on panels, and standards that are actually enforced, so that bad systems don't teach people that solar doesn't work (chapter 10).

But notice what the price is anchored to. A ₦315 kWh is a very good deal for someone paying ₦630 for diesel. For a factory deciding whether to make something in Nigeria or import it, it's still more than twice what manufacturers pay in most of the countries Nigeria competes with. This rung displaces diesel. Making Nigeria competitive takes the next one.

Priced at cost

The second rung is the first one that needs a decision. A government, a pension fund, or a development finance institution acting with government backing can afford to be more patient than commercial capital. Suppose public capital accepted a seven-year payback on the same systems.

Using the numbers from chapter three, a ₦7 million system producing 8,000 useful kWh a year with a seven-year payback means charging about ₦125 per kWh. At the scale price of around ₦4.5 million per system, that falls to about ₦80 per kWh. That's well below Band A grid power, about a ninth of the all-in cost of diesel at scale, and available 24 hours a day.

Why should public capital accept a lower return? Because the return to the country is far higher than the return on the asset. A government that finances solar at a seven-year payback is buying:

• Competitive production. Factories, farms and workshops paying under ₦150 instead of ₦700 per kWh can compete with imports and, eventually, export.
• Foreign exchange. Every litre of generator fuel displaced is world-priced fuel Nigeria no longer has to buy.
• Household income. The ₦13 trillion a year now burned in generators is money that could go to food, school fees and investment.
• Health and quality of life. Less smoke, less noise, fewer deaths from fumes and fires.
• Fiscal room. Cheap distributed power reduces pressure on a grid that has absorbed decades of subsidy.

Here's the number that I think makes the case. This rung is the size of the generator fleet: replacing its output, around 19 TWh a year, would take something like 15–25 GW of solar and 30–40 GWh of batteries, depending on how well systems match their loads. At scale prices of about $340 per kW installed, battery included, that's roughly $5–9 billion. Nigeria spends about $10 billion a year on generator fuel alone.

At scale prices, the whole self-generation fleet could be replaced for less than one year's fuel bill.

Abundance

Pricing at cost makes power cheaper than the grid. Abundance is what happens when it's cheap enough, and reliable enough, that people stop rationing it.

That's a bigger change than it sounds. Almost every Nigerian household and business manages electricity as a scarce good: the generator goes on at 7pm and off at midnight, the AC runs in one room, the freezer is switched off overnight to save fuel. The model in chapter three shows what happens when that constraint lifts. A household that ran its generator only in the evening ends up using thousands of kWh a year more than before. Across the country, that's how demand grows three- to fivefold (chapter 8).

It's also the rung where the fleet grows to match what people want to do with power. Meeting the demand stack in chapter 8, ~180–250 TWh a year, mostly from solar, takes something like 100–200 GW of panels and 150–400 GWh of batteries: the 100 GW stage in chapter 9 and beyond.

Abundance needs two things the lower rungs don't.

The first is storage, because abundance means power at 9pm as well as at noon. The model in chapter three points to 1.5–2 kWh of battery per kWp of panels for a system that replaces a generator, and roughly half of the solar that reaches the load passes through the battery first, because so much Nigerian demand comes after dark. For the generator fleet alone that means 30–40 GWh of batteries; at today's Lagos retail price of about $95/kWh, roughly $3–4 billion, already inside the total above. For the abundance fleet it means 150–400 GWh, which is why falling battery prices matter as much as falling panel prices.

The second is tariffs that reward use. A utility trying to cover its fixed costs from a shrinking customer base raises its unit price. An electrostate wants the opposite: low, flat or falling prices for each extra kWh, especially for anyone using power to produce something. This is the clearest test of whether a government means it. Does it treat a kWh as a source of revenue, or as an input to the rest of the economy? Every naira added to the price of a kWh, whether through levies, duties on panels or tariffs that protect weak local manufacturers, is a tax on everything the country makes.

Super-abundance

Solar has a property no fuel has: the more of it you build, the more hours of the day it produces more than anyone can use.

You can already see this on Lagos rooftops. On a typical home system, around half of what the panels produce goes unused, because it arrives at midday when the battery is full and the house is empty. Today that power is thrown away. In California, South Australia and parts of Europe, so much solar now comes on at midday that wholesale prices regularly fall to zero or below.

An electrostate plans for that surplus and puts it to work. Panels are now the cheapest part of a solar system, so the cheapest way to have enough power on cloudy days and through the rainy season is often to overbuild them and accept a midday surplus for most of the year. The strategy is then to build things that can use power whenever it's nearly free:

• Water: pumping for irrigation and treatment, storing water rather than electricity
• Cold: ice-making and cold rooms that bank the midday surplus as cold for the evening
• Fertiliser: ammonia made by electrolysis in the hours when power is cheapest
• Processing: drying, milling and processing crops in daylight
• Computing: data centres with flexible workloads that run hardest at noon
• Transport: charging okada, keke and bus batteries at midday swap stations (chapter 6)

None of these happens by accident. They need the surplus sold to them cheaply: rules that let rooftops sell into estates, mini-grids and the grid; time-of-day prices that pass the near-zero midday cost on to whoever can use it; and industrial parks sited where the surplus is. This is the rung where government intent matters most, because it's the one the market is least likely to reach on its own. A single investor has no reason to overbuild. A country does.

The surplus arrives well before the terawatt. At around 100 GW, panels on a clear day at noon would produce roughly twice what the whole country uses at that hour. Everything built beyond the ~200 GW that abundance needs is deliberate overbuild, and the terawatt in chapter 9, with 1.5–2 TWh of batteries, is where that strategy leads: about 1,400 TWh a year, 3,500–4,000 kWh per person, much of it at midday and nearly free.

Choosing cheap

Put together, the ladder is an industrial strategy, and the strategy is a price. I'd suggest Nigeria set a target for what a kWh of industrial power should cost, the way a central bank sets a target for inflation, and judge every energy policy by whether it moves the country towards that number.

The machinery could be simple:

• Public capital, private delivery. Government and pension money provides long-term naira finance; private installers design, install and maintain the systems, paid on performance.
• Local currency, long tenors. Nigerian pension assets run to tens of trillions of naira. Even a small allocation to infrastructure bonds backed by solar assets would transform the market.
• Bulk procurement. Buying hardware at national scale at factory prices, with quality standards built in.
• Anchor-first rollout. Start with industrial parks, export zones, markets, hospitals and cold chains, then extend to the communities around them.
• No taxes on the kWh. Keep duties, levies and protective tariffs off panels, batteries and the power they make.
• A grid that buys the surplus. Let rooftops, estates and mini-grids sell midday power to whoever can use it.
• Independent monitoring. Every system metered and visible, so performance is verifiable and fraud is hard.

The risks are obvious, and Nigerians know them better than anyone: procurement corruption, politically chosen projects, white elephants. Design is the defence. If private firms are only paid when systems produce verified kilowatt-hours, there's much less room for waste.

A petrostate makes its money by selling energy dear. An electrostate makes its money by selling energy cheap, at home, and putting it into everything the country makes.

Chapter 8

The real prize

Nigeria uses astonishingly little electricity. Comparable data puts consumption at about 144 kWh per person per year, against 351 in Ghana and 4,198 in South Africa. Adding self-generation lifts Nigeria to perhaps 200–250 kWh per person, still a fraction of its neighbours'. One analysis estimated that, counting latent and suppressed demand, Nigerian per capita consumption should be four to five times its current level.

The model in chapter three shows that suppressed demand at the scale of a single home. A household that runs its generator only in the evening, once given solar and a battery, ends up using roughly 5,500 kWh a year more than before: power it always wanted and couldn't afford.

That gap is the market. Here's a rough stack of where demand could come from by around 2040, for a population of roughly 300 million:

Generator displacement, the whole of chapters 2 and 3, turns out to be about a tenth of this.

Three further layers sit beyond the table because they're harder to size but potentially larger:

• Selling the surplus. A quarter to a third of rooftop output goes unused at midday. Across millions of roofs, that's a distributed power station nobody is paying for yet. Neighbour-to-neighbour sales, estate-level networks and mini-grids that buy from rooftops could turn spilled power into income.
• Energy-intensive exports. Fertiliser from green ammonia, aluminium and other metals, food processing and data centres all compete on the price of power. A country selling electricity at ₦80–150/kWh, while its neighbours run on diesel, has a real industrial advantage.
• Regional trade. Nigeria sits at the centre of a West African market of over 400 million people. Cheap power can be exported directly over the regional grid, or embedded in exported goods.

Priced at even ₦150/kWh, 200 TWh a year is a ₦30 trillion annual market, more than twice what Nigerians spend on generator fuel today. And it's served by an asset that, once built, burns nothing.

This is why I think people are underestimating the space. They size the market as "the diesel bill." The diesel bill is the proof that demand exists. The real market is everything Nigerians would do with electricity if it were cheap and always on.

Chapter 9

Stages to a terawatt

My central claim is that Nigeria should, can and probably will reach a terawatt of solar in my lifetime. That sounds absurd today. It sounds less absurd when you break it into orders of magnitude and ask what each stage looks like and what has to be true.

Stage 0: about a gigawatt (where we are). Nigeria imported 1.7 GW of panels in the year to mid-2025 and millions more panels through 2025. Installed capacity is probably in the low single-digit gigawatts once you account for stock sitting in warehouses and small, low-quality panels. Early adopters are wealthier households, banks, telecoms, some factories and estates. Diesel and petrol generators still produce far more electricity than solar.

Stage 1: 10 GW and ~15–20 GWh of batteries (by 2030). At this stage solar displaces a large share of C&I and middle-class generator use. EaaS and lease-to-own become normal ways to buy power. Okadas and kekes begin to electrify in the major cities.

What has to be true: annual installations of around 2 GW, finance available at scale for C&I and SMEs, enforced quality standards, and no policy shocks (a point I return to in the next chapter).

Prediction: By 2030, Nigeria will have 10 GW of installed solar, and generator fuel consumption will be at least a third below its 2025 level.

Stage 2: 100 GW and ~150–200 GWh of batteries (by around 2042). At this point solar is the backbone of Nigerian electricity. Generators survive mostly as emergency backup. The grid carries utility-scale solar and storage alongside gas. Most two- and three-wheelers are electric, and buses are following. Panels and batteries are assembled in Nigeria at scale. 100 GW produces around 140 TWh a year, roughly two and a half times today's grid and self-generation combined, and most of the way to the demand stack in chapter 8.

What has to be true: a national finance facility of the kind described in chapter seven; a reformed grid that can buy, carry and balance distributed solar; local manufacturing (domestic module capacity grew from about 110 MW to around 600 MW between 2023 and 2025, a start); and average installations of about 7–8 GW a year through the 2030s. That sounds like a lot until you remember Pakistan, with a similar population, installed 17 GW in a single year.

Predictions: By 2035, a majority of new okadas and kekes sold in Lagos will be electric. By 2042, Nigeria will have 100 GW of solar, more than any other African country.

Stage 3: 1 TW and ~1.5–2 TWh of batteries (by around 2070). A terawatt of solar produces around 1,400 TWh a year. For a population that may reach 350–400 million, that's roughly 3,500–4,000 kWh per person, approaching what Britain uses today. At this stage trucks and most industry are electric, Nigeria makes its own fertiliser from green ammonia, processes its own crops and minerals, runs data centres for the region, and exports goods made with cheap power.

What has to be true: installations averaging around 30 GW a year from the 2040s onwards; a manufacturing base for panels, batteries and electrical equipment; a high-voltage grid that moves power across the country; something firm for the rainy season, when solar output falls by a fifth to a quarter (gas, hydro, or deliberately oversized solar); and an economy that has learned to use cheap electricity productively.

Is 30 GW a year realistic? China installed well over 250 GW of solar in 2024 alone. Thirty gigawatts a year is about a tenth of that.

What about land? Utility-scale solar takes roughly 1.5–2 hectares per megawatt. A terawatt would need about 15,000–20,000 km², around 2% of Nigeria's land area, and much of it would sit on rooftops, over car parks, or above crops grown in partial shade.

Prediction: Nigeria will reach 1 TW of installed solar before 2075.

Chapter 10

What could change

Predictions this far out will be wrong in the details. The question is whether they're wrong about direction or only about speed. Here's what could shift the pace.

Technology gets cheaper faster. Sodium-ion batteries, perovskite-silicon tandem panels and continued manufacturing scale could push costs down faster than the curve suggests. That would accelerate everything in this essay, especially stages two and three.

Oil shocks. A price spike, like the one in early 2026, speeds things up: every rise in diesel is a better sales pitch for solar. An oil price collapse would slow things down, but not reverse them. Even at ₦1,000 a litre, half of today's price, diesel's fuel cost would be over ₦300/kWh, still above what financed solar costs and four times its unfinanced lifetime cost.

Currency. Devaluation hits fuel and hardware roughly equally, so the comparison barely moves. The damage falls on finance: naira contracts and dollar debt don't mix. Local manufacturing and local-currency capital are the long-term answers.

Policy. This is the biggest risk to pace. Bad policy can slow the transition badly. When an outright import ban was floated in early 2025, first-quarter panel imports fell 89%. Pakistan, which had exempted panel imports from duties and sales tax, imposed a 10% sales tax on new imports in 2025. Grid rules that penalise self-generation, or tariffs that protect weak local manufacturers at the expense of everyone else, would cost Nigeria years. Good policy (standards, local-currency finance, a grid that welcomes distributed power) could compress the timeline just as dramatically.

A working grid. If the grid were fixed tomorrow and delivered reliable power at ₦210/kWh, rooftop solar's advantage would narrow, as the Band A rows of the payback table show. But a grid fixed in a world of cheap panels and batteries would itself be built largely on solar and storage. The terawatt arrives by a different route.

Why the direction holds. Strip everything else away and the argument comes down to this: fuel is dug out of the ground, and panels and batteries are made in factories. Things that are dug up don't get systematically cheaper; things that are manufactured do, every year, for as long as production grows. Nigeria pays for electricity mostly in fuel, at some of the highest prices on Earth, and sits under some of the strongest sunshine on Earth. The gap between those two facts will keep widening.

The pace will depend on finance, policy and how quickly we build the industry. The direction is already set.

Every Nigerian generator is burning sunlight that fell hundreds of millions of years ago. The same sunlight is falling on the roof above it today, for free. We are going to learn to use it.
