Africa’s Electricity Grid Is Being Re-engineered

Last Updated 1 hour ago by Kenya Engineer

For decades, the central question in African electricity development was relatively simple: how do you generate more power and connect more people to it?

That question has not disappeared. But it is being joined by a more complicated one. As solar, wind and geothermal capacity expand, industries become more electricity-intensive and new technologies such as batteries and electric vehicles enter the system, how should the grid itself be redesigned to cope with a much more complex electricity landscape?

The answer is increasingly visible in projects being developed across Africa. Transmission lines are being built not simply to connect consumers to power stations, but to move renewable electricity across regions. Battery systems are beginning to provide services traditionally associated with conventional generators. Countries are strengthening cross-border interconnections and power markets. And private investors are entering transmission infrastructure, historically one of the most difficult parts of the electricity value chain to finance.

The International Energy Agency says the transformation is now a global engineering priority. More than 2,500 GW of renewable generation, storage and large-load projects, including data centres, are currently stalled in grid-connection queues worldwide. The IEA estimates that annual grid investment will need to rise by roughly 50 per cent from today’s level of about US$400 billion by 2030 if electricity demand is to be met.

For Africa, the challenge is both larger and more complicated. The continent needs to expand electricity access while simultaneously building the infrastructure required for an energy system that is increasingly renewable, decentralised, interconnected and digital.

Kenya offers a useful window into that transition.

From generation to system architecture

Kenya’s National Energy Compact sets out an ambitious expansion of the electricity system by 2030. The country is targeting 100 per cent clean-energy generation capacity, compared with 83 per cent in its 2024 installed-capacity baseline.

The numbers behind the transformation are substantial. Kenya plans to increase installed geothermal capacity from 943.7 MW to 1,681 MW, wind from 436.1 MW to 966.1 MW and solar PV from 442.9 MW to 806.9 MW. It also targets 400 MWh of battery energy storage, compared with no utility-scale BESS in the 2024 baseline.

But generation is only one part of the equation.

The same plan calls for the transmission network to grow from 9,484 km to 17,500 km, an increase of about 8,000 km, while transformation capacity is targeted to rise from 12,410 MVA to 24,410 MVA. Distribution infrastructure is expected to expand by more than 212,000 km by 2030.

Those figures illustrate a fundamental point. Kenya’s energy transition is not simply a programme for installing more renewable power plants. It is a programme for rebuilding the physical and digital infrastructure that allows electricity to move from where it is generated to where it is needed, when it is needed.

That is a very different engineering problem.

Transmission is becoming an investment class

One of the most significant developments in Kenya is the emergence of private-sector participation in transmission.

In December 2025, Kenya Electricity Transmission Company signed a US$311 million public-private partnership with Africa50 and Power Grid Corporation of India for two high-voltage transmission projects.

The flagship component is an approximately 180 km, 400 kV double-circuit Lessos–Loosuk line, accompanied by a new 400/220 kV substation at Lessos and a 400 kV switch station at Loosuk. The project is intended to provide an alternative evacuation route for up to 300 MW from Lake Turkana Wind Power and to support future geothermal generation from the North Rift.

The significance goes beyond the physical line.

KETRACO’s Acting Managing Director, Eng. Kipkemoi Kibias, said the company expects to require about US$5 billion to develop an additional 8,000 km of transmission lines over the next 20 years.

“KETRACO is currently able to mobilize only a fraction” of the roughly US$250 million annual requirement through traditional sources, Kibias said when the PPP was signed. The company is therefore deliberately turning to private-sector participation to bridge the financing gap.

Africa50 CEO Alain Ebobissé described the Kenyan transaction as potentially providing a model for other African countries, arguing that transmission networks are critical to closing the continent’s electricity-access gap.

This is an important shift in the economics of African power infrastructure. Transmission has traditionally been seen largely as a public-sector responsibility because of its strategic importance and the difficulty of recovering investment directly from users. Kenya’s independent transmission model suggests that private capital may increasingly become part of the solution.

The grid also has to become flexible

More generation and more transmission will not, by themselves, solve the problem.

Wind and solar introduce variability into the electricity system. Electricity demand is also becoming more dynamic, with industrial loads, electric vehicles, distributed solar, data centres and other large consumers potentially changing their consumption patterns rapidly.

This is where energy storage becomes important.

KenGen is currently conducting a feasibility study for a 100 MW/100 MWh battery energy storage system distributed across Olkaria, Kipevu, Embakasi and Muhoroni. The company identifies load balancing, shifting, frequency and voltage support, renewable-energy integration and reduction of curtailment among the potential applications.

The technology is already moving beyond the pilot stage elsewhere in Africa.

In Malawi, a 20 MW/40 MWh grid-forming battery system at Kanengo Substation entered commercial operation in July 2026. The project was described as the country’s first utility-scale BESS and is designed to strengthen grid reliability and support the integration of renewable energy.

In the Democratic Republic of Congo, the engineering proposition is even more striking.

A 233 MWp solar plant paired with a 526 MWh battery system at the Kamoa-Kakula copper complex reached commercial operation in August. The system is designed to provide 30 MW of firm, round-the-clock power to the mine.

Richard Stanford, CrossBoundary Energy’s chief technical officer, told African Business that the project was demonstrating that the technology was working as intended.

The significance is not that solar has suddenly replaced baseload generation. Rather, the project demonstrates a different engineering approach: generation and storage can be designed together to provide a predictable industrial electricity supply.

That opens another possibility for Africa. In areas where national grids are weak or transmission projects would take many years, large industrial customers could increasingly become anchors for new renewable generation and storage systems.

Africa is beginning to operate as a regional electricity system

The next stage is not only about strengthening national grids. It is about connecting them.

In June 2026, the World Bank approved a US$1.6 billion, 10-year programme for regional energy transmission, trade and decarbonisation in Eastern Africa.

The RETRADE-EA programme includes support for cross-border infrastructure, the Eastern Africa Power Pool, regional system planning and the development of a day-ahead electricity market. Its first phase includes the Uganda-Tanzania Interconnector Project, involving approximately 260 km of 400 kV double-circuit transmission line with a planned transfer capacity of 1,000 MW.

The World Bank’s Regional Vice President for Eastern and Southern Africa, Ndiamé Diop, described a well-integrated regional energy market as a catalyst for economic growth and job creation.

For engineers, regional interconnection changes the design problem yet again.

A country no longer has to build enough generation to satisfy every possible condition on its own. Surplus hydroelectricity in one country can potentially serve demand in another. Geothermal, wind and solar resources can be traded across borders. Regional diversity in weather and demand can improve system balancing.

But that requires more sophisticated protection systems, synchronisation, forecasting, control, telecommunications, metering, settlement systems and operational coordination.

The physical grid is becoming a regional digital system.

The control room is becoming as important as the substation

This is perhaps the least visible part of the transition.

A modern renewable-heavy electricity system requires much better visibility of what is happening across the network. System operators need to know not only how much electricity is being generated, but where it is coming from, how rapidly it is changing and how much flexibility is available elsewhere in the system.

Kenya’s National Energy Compact explicitly includes modernising the transmission network and SCADA system alongside the expansion of transmission capacity.

That is significant because the future grid will depend increasingly on digital technologies that can observe, predict and respond to system conditions.

Artificial intelligence will also have a role. The IEA notes that AI can already be used to monitor grids, transformers and other energy equipment, reduce unexpected failures and optimise the use of existing grid capacity.

In other words, the grid itself is becoming an information system.

The coming collision between generation and new loads

There is another reason the grid has to evolve quickly.

Electricity demand is beginning to change in ways that were not anticipated when much of Africa’s power infrastructure was designed.

Electric vehicles will add new loads. Industrialisation will increase electricity consumption. Cold chains and electric cooking will expand. Mining companies are seeking reliable power for increasingly automated operations.

And then there are data centres.

A large AI data centre can represent a concentrated load of 100 MW or more. In Kenya, plans for a 44 MW AI-ready facility at Tatu City and a recently expanded 6.4 MW Nairobi facility illustrate the direction of the market.

The grid therefore has to become capable of accommodating not only more generation, but much larger and more sophisticated consumers.

This is where the two sides of the energy transition meet.

Africa is simultaneously trying to connect millions of people to electricity, decarbonise generation, expand industrial capacity, build digital infrastructure and integrate new technologies.

The engineering challenge is no longer just producing more electrons. It is to make the entire system capable of moving, storing, controlling and trading those electrons efficiently.

Designing the grid Africa actually needs

Africa’s electricity future will not be built around one technology.

Geothermal will remain important in Kenya. Hydro will remain strategically important across East and Central Africa. Wind and solar will continue to expand. Batteries will become more significant. Regional interconnectors will allow countries to trade power. Distributed generation and mini-grids will fill some gaps that national networks cannot economically reach.

The engineering challenge is to make those components work together.

Kenya’s 8,000 km transmission expansion target, the Lessos–Loosuk independent transmission project, KenGen’s proposed battery programme, Malawi’s grid-forming BESS, the DRC’s solar-and-storage industrial system and the Eastern Africa Power Pool’s developing regional market are not isolated developments.

Together, they point towards a different electricity architecture.

The traditional power system was built around large generators, long transmission lines and relatively predictable consumers.

The emerging system will have multiple generators, batteries, flexible loads, distributed resources and cross-border electricity markets, all coordinated through increasingly digital control systems.

That will demand new thinking about protection, system stability, planning, tariffs, financing, cybersecurity, equipment standards and engineering skills.

The race to build Africa’s next electricity system is therefore not just a race to install more megawatts. It is a race to build the grid capable of making those megawatts useful.

And that, for Africa, may prove to be the defining engineering challenge of the next decade.
