On a recent Friday morning north of Johannesburg, the head of South Africa’s largest telecoms company surveyed the arsenal of backup systems keeping just one of his 15,000 network towers online amid the worst power cuts.
A diesel generator, solar panels, a bank of expensive backup batteries and theft-proofed within a block of concrete.
“Our costs have gone through the roof,” lamented Sitho Mdlalose, managing director of Vodacom South Africa.
As the national power grid crumbles, leaving Africa’s most advanced economy in the dark for up to 10 hours daily, mobile operators, including Vodacom, MTN, and the majority state-owned Telkom, are scrambling to ensure their networks stay up and running.
Three company executives told Reuters that they’re spending millions to install solar panels and batteries and trialing wind turbines while targeting deals with independent power producers to supplement struggling state utility Eskom’s increasingly unreliable output.
At stake: Essential voice and data services in a nation where landlines are rare, but nearly 80% of residents have access to mobile internet.
According to the South African Reserve Bank governor, the power crisis and logistical constraints will erase two% points from economic growth this year.
Mary-Jane Mphahlele, an attorney who also runs a small travel agency in the city of Polokwane, experiences that loss of economic activity every time the power is cut.
“New clients can’t call me ... That means no money will come into my business,” the 29-year-old said. “It’s hell.”
Telecommunications companies have seen operating costs balloon as they battle to mitigate the worsening crisis. As a result, Vodacom and MTN executives told Reuters they must divert capital from much-needed network upgrades and 5G rollouts.
Meanwhile, they said government regulations are blocking potential solutions, such as sharing backup power infrastructure with their competitors, and revealed they’re lobbying authorities to help ease the pain.
“Government and business must jointly seize this moment,” MTN Group Chief Executive Ralph Mupita told investors last month. “If we do not act as a country, we risk becoming a failed nation-state.”
South Africa’s power crunch – the product of years of corruption, a failure to add generating capacity, chronic breakdowns, and under-exploited renewables capacity – has hobbled the economy and sparked public anger.
President Cyril Ramaphosa declared a national disaster in February, calling the crisis an existential threat to South Africa’s social fabric.
In the past year, power outages have cost South Africa’s number two operator, MTN, some 640 million rands ($36 million) in service revenue, forcing it to downgrade its medium-term margin target.
Telkom incurred over 150 million rands in additional costs in its third quarter ended in December 2022 alone.
Vodacom – majority owned by London-listed Vodafone – is spending well over 300 million rands a year on incremental costs, including fuel, battery replacements, repairs and security, Mdlalose told Reuters.
While most network towers in South Africa have a battery for backup power, more advanced systems are less common. MTN, for example, has 12,900 towers in South Africa but only around 3,000 diesel generators and solar panels at a few pilot sites.
Officials said companies concentrate those extra resources on high-revenue sites, mainly in larger metro areas. But even city residents struggle when hours-long outages outlast backup measures.
“You just have to wait for the electricity to come back or move around town to get network,” said lawyer and businessperson Mphahlele, who lives in the provincial capital of around a half million residents.
MTN is deploying capital expenditure of about 9 billion rands in South Africa, with most going towards rolling out longer-lasting batteries and diesel generators, CEO Mupita told reporters last month. In addition, Telkom is deploying energy solutions to over 200 key sites.
Vodacom is also expanding battery use and installing solar panels at sites where space allows, Mdlalose said.
But it’s a zero-sum game forcing other important projects onto the back burner.
“We’ll probably slow down on advanced CAPEX-related portfolios like accelerating 5G,” MTN Group Chief Financial Officer Tsholofelo Molefe told Reuters.
Vodacom expects to slow its rural network drive and redirect those funds to back up power rollouts.
That risks delaying South Africa’s pivot to the digital economy and could leave rural areas, which already suffer from sparse coverage, lagging even further behind.
The challenges aren’t simply financial. As telecoms ramp up their efforts, criminal gangs are doing the same, targeting newly installed generators and batteries and stealing fuel.
At a tower site shared by Vodacom and MTN in Soweto, a large township south of Johannesburg, thieves recently bashed through concrete to make off with cables, radio transmitter processors and an air conditioner.
Mdlalose said Vodacom sees 600 and 700 such attacks monthly and loses around 5,500 batteries annually to theft.
MTN did not share data on its overall losses to criminal activity but said it’d witnessed a sharp rise in incidents, including cable and battery theft. As a result, it will begin placing some battery systems inside concrete bunkers.
With the costs mounting, mobile operators are turning to the government for help.
MTN is seeking a temporary relaxation of visa regulations to bring in foreign technicians, including from Nigeria, where towers are heavily reliant upon diesel generators, Mupita told MTN’s investors.
It’s also seeking clarity on whether the state of disaster permits mobile operators to allow each other to roam across networks to avoid dropped calls freely, MTN’s CFO Molefe told Reuters.
That could bypass lengthy approval processes and avoid limitations on locations where roaming is permitted and which spectrum bands companies can roam on.
Telcos also want the same fuel rebates enjoyed by the agriculture and mining sectors, according to Nomvuyiso Batyi, CEO of the Association of Comms and Technology.
And they’re seeking to save on costs by jointly purchasing and operating backup power equipment, she and Vodacom’s Mdlalose added.
The regulatory body that oversees the sector said it was considering measures “to ameliorate the impact of load-shedding on service provision, economic activity, and social well-being.”
And the government’s Competition Commission told Reuters the Minister of Trade, Industry and Competition was considering public input as his department drafts exemptions for power users under the state of the disaster.
The final regulations, which Vodacom’s Mdlalose considers a lifeline for the industry, have yet to be published.
“Frankly, if we’re not allowed to do that, it would be a real tragedy,” he said. “This is a national crisis.”
