Energy Efficiency is Key to the Sustainability of Data Centres in Africa

Access to affordable, reliable and environmentally sustainable sources of electricity is a pressing issue for the growing number of Data Centre operators across Africa. These facilities need to ensure a high availability of power to mitigate downtime, but many African countries face frequent power outages.

Existing Data Centres have relied on diesel-fuelled generators to sustain operations during power outages, a practice that could exacerbate carbon emissions in the future. Indeed, the deployment of hyperscale Data Centre capacity is expected to increase emissions through further diesel-generator utilisation.

In a recently published focus report by Oxford Business Group titled “Data Centres in Africa”, the CEO of MainOne, Funke Opeke opined that power distribution networks are facing frequent shortages, but there is an adequate supply of electricity in the region’s national grids.

“By strategically locating our Data Centres close to sources of power and partnering with local power distribution companies to build direct connections to the national grid, we ensure high power availability and reduce the utilisation of diesel-fuelled power generation at our facilities” she states.

MainOne has increased the capacity of its Data Centres, which reached 5 MW in the key markets of Nigeria, Ghana and Côte d’Ivoire, with services delivered to a total of 10 countries across West Africa. Its data centre subsidiary, MDXi, runs energy-efficient facilities by optimising airflow, using sensors and artificial intelligence to manage operations, and installing energy-efficient hardware. Taken together, these actions go a long way towards reducing the carbon footprint and improving energy efficiency for the sustainability of its Data Centres.

Following the launch of its Tier III Data Centre in Appolonia City in Accra, Ghana earlier in the year, MDXi has commenced the expansion of its Lekki data center in Lagos, Nigeria, with the goal of increasing its 600-rack facility to over 1200 racks by 2023.

Further investments have also been directed towards the expansion for its Data Centre in Côte d’Ivoire.

Africa is experiencing some of the fastest growth in internet access seen around the world, largely due to its young population. As such, data consumption will continue to grow for the foreseeable future.

This will fuel further investment in submarine cables and Data Centres to bring data closer to consumers. However, without sustainable power strategies, the industry will continue to contribute to global warming in a region that can least afford the consequences.

Nigeria has recorded an 84 Percent  decline in spam SMS after Airtel Africa deployed its Artificial Intelligence-powered spam detection tool, Spam Alert.

Airtel AI Blocks 84 Percent of Spam SMS in Nigeria

According to Airtel, the free service has flagged over 205 million fraudulent and unsolicited messages across 13 African markets within six months.

Nigeria registered the sharpest decline, while Kenya recorded the highest flagged spam volume with 68 million messages, followed by Tanzania with 47 million and Zambia with 33 million.

Spam Alert prefixes suspicious SMS with “SPAM Alert,” providing users with real-time protection against phishing scams and nuisance texts without requiring extra applications.

Sunil Taldar, CEO, Airtel Africa, said the solution demonstrates the company’s commitment to tackling digital fraud as smartphone penetration expands across Africa.

Currently active in 13 of Airtel’s 14 markets, including Nigeria, Uganda, Zambia, and Tanzania, the service has cut overall spam SMS by 12% across the continent. Seychelles will join soon, Airtel confirmed.

In Nigeria, Airtel reported that between March 13 and May 20, 2025, the system intercepted more than 9.6 million suspicious messages, of which over 9.1 million originated from off-network sources. T

he AI-powered system scans all SMS in real-time using 250 parameters, including sender identity, link structure, and regional anomalies, processing each message in under two milliseconds without storing content.

The Nigerian Communications Commission (NCC) welcomed the innovation.

Dr. Aminu Maida, executive vice chairman, said the initiative strengthens consumer protection at a time when spam and fraud are growing more sophisticated. He stressed the need for more collaboration between operators and regulators to reduce digital risks.

The NCC’s 2023 Industry Risk Report had ranked phishing and bulk unsolicited messaging among the top threats facing subscribers, especially in rural areas and among first-time smartphone users.

Airtel’s initiative is expected to ease these concerns by reinforcing trust in mobile communications.

Why Elon Musk Halted Sales of Starlink in Lagos, Abuja

Starlink, the satellite internet provider operated by Elon Musk’s SpaceX, has stopped taking new orders for residential kits in parts of Lagos and in Abuja after network capacity was reached, the company’s online ordering page shows.

starlink

Neighborhoods listed as sold out include Victoria Island, Ikoyi, Lagos Island and Surulere.

Prospective customers in those areas can join a wait list by paying a deposit and will be notified when service space opens.

At Chevyville Estate in Lekki, one resident trying to subscribe was met with a message that read: “Starlink service is currently at capacity in your area. However, you can place a deposit now to reserve your spot on the waitlist and receive a notification as soon as service becomes available again.”

That experience mirrors what consumers in other busy districts are seeing.

A Starlink engineer who spoke on condition of anonymity to discuss internal limits said the company temporarily closes new sales in zones where adding customers would degrade service for existing users.

“It happens when the area cannot take a new customer due to its designed capacity at the time,” the engineer said.

“This also helps preserve a steady connection for people already online.” Remedies can include adding more ground infrastructure, securing regulatory clearances, or expanding satellite coverage.

Since entering Nigeria, Starlink’s monthly fee has climbed: the service began at about N38,000 (roughly $25), rose to about N45,000 ($30) and — by 2025 — was charging roughly N56,000 ($37).

Starlink has cited naira depreciation, higher operating expenses and costs tied to meeting rules set by the Nigerian Communications Commission for the increases.

Those higher prices, and the service interruptions, appear to have affected subscription numbers. After a near eight-month pause that began in November 2024 and was tied to limited bandwidth and regulatory issues, orders resumed in late June 2025.

Still, data from the NCC show active Starlink users in Nigeria fell from 65,564 in the fourth quarter of 2024 to 59,509 in the first quarter of 2025, a decline of more than 6,000 users, or about 9 percent.

Analysts point to the price rises, service holds and economic pressure as key reasons for the drop; some customers have switched to cheaper alternatives or stopped service.

As Elon Musk maintains his position as the world’s richest individual, with a net worth of $429 billion (according to the Bloomberg Billionaires Index), his commitment to global digital inclusion through Starlink remains a central focus.

Starlink’s activity in Nigeria is part of a wider push across Africa.

The company has recently moved to enter markets including Lesotho and Somalia and secured permission to operate in the Democratic Republic of Congo after earlier restrictions,

SpaceX is also working with operators such as Airtel Africa to reach rural areas where wired internet is scarce.

For many users in Nigeria, the appeal of Starlink remains clear: a reliable option where terrestrial networks falter.

But until the company expands capacity or adjusts pricing, consumers in dense urban pockets may have to wait for access or turn to other providers.

Google has announced a new set of investments in Africa, reaffirming its nearly two-decade commitment to the continent’s digital transformation.

The latest commitments focus on empowering Africa’s next generation through AI, unlocking opportunities and expanding on the innovation capacity of young Africans. They cover internet connectivity; youth-led learning and innovation; and skills training.

Connectivity

Google is announcing four strategic subsea cable connectivity hubs in the north, south, east and west regions of Africa. This investment creates new digital corridors within Africa and between Africa and the rest of the world – ultimately deepening international connectivity and resilience, as well as spurring economic growth and opportunity.

This is the latest addition to Google’s Africa Connect infrastructure program, which sees the company build vital connectivity across the continent: including the Google Cloud region in Johannesburg serving users across the continent, the Equiano cable running along the entire western seaboard of the continent, and Umoja, the first fiber optic route to directly connect Africa with Australia (running through Kenya, Uganda, Rwanda, Democratic Republic of the Congo, Zambia, Zimbabwe and South Africa).

Google’s investments to date have enabled 100 million Africans to access the internet for the first time, and the Equiano cable alone is expected to increase real GDP this year in Nigeria, South Africa and Namibia by an estimated $11.1 billion, $5.8 billion and $290 million, respectively.

Youth-led learning and innovation

Enabling Africa’s young people to learn, innovate and lead is critical to Africa’s development and economic growth. That’s why Google is today also announcing free one-year subscriptions to Google AI Pro plan for college students (18 or older) across the continent – starting with Egypt, Ghana, Kenya, Morocco, Nigeria, South Africa, Rwanda and Zimbabwe. The subscription provides advanced AI to students – from Deep Research, which helps save time with custom research reports and in-depth information from hundreds of sources across the web, to Gemini 2.5 Pro, which provides help with assignments or writing.

Building skills and solutions

Equipping people with AI skills is critical. To date, Google has trained 7 million Africans and plans to train an additional 3 million students, young people, and teachers by 2030. Google is also bolstering local capacity by providing African universities and research institutions with over $17 million in funding, curriculum, training and compute and access to advanced AI models over the past four years – with an additional $9 million planned for the coming year.

On the announcements, Alex Okosi, Managing Director for Google in Africa, said: “Africa’s digital economy holds immense potential, and it will be driven by the talent and ingenuity of its next generation. Today’s announcements, spanning AI education, advanced tools for students, and expanded connectivity, are a unified investment into the upward trajectory of the continent.

“We are committed to providing the foundational infrastructure, the cutting-edge tools, and the financial support necessary for Africa’s youth to innovate, lead, and build a thriving digital world.”

Google’s long term partnership

These announcements are the latest chapter in Google’s long-term investment in the continent, which has delivered on $1 billion of investment. Google’s sustained commitment to Africa has included driving connectivity; training more than 7 million people across the continent in digital skills to support the future workforce; and supporting 153 startups from 17 African nations through the Google for Startups Accelerator Africa, helping them raise $300 million and create 3,500 jobs.

AI creates an unprecedented opportunity to benefit everyone, and Google is committed to making that a reality for people, businesses and communities across Africa. Today’s announcements are another example of how Google is continuing to expand connectivity, increase product access and skills across the continent and enable African-led innovation – with more to come.
