Orange S.A. (EPA: ORA), France’s largest telecommunications operator, plans to double the number of solar-powered mobile base stations across Africa and the Middle East as higher fuel prices and unreliable electricity supplies strengthen the commercial case for renewable-energy investments.

Speaking to Bloomberg Television during the Africa-France business summit in Nairobi, group chief executive Christel Heydemann said the fallout from the conflict involving Iran had increased the attractiveness of solar investments across the company’s African operations.

“The current crisis in the Middle East is making the business case even more sustainable,” Heydemann said.

According to Orange’s 2025 annual report, the company has already deployed solar-energy systems at around 15,000 sites across 11 countries in Africa and the Middle East, representing roughly 30% of its regional network infrastructure.

Heydemann said Orange intended to double that number, although she did not specify a timeline and said a formal announcement would be made soon.

The solar expansion forms part of a broader €5bn ($5.7bn) investment programme planned across Africa and the Middle East over the next three years, regions that have become key growth drivers for the French telecoms group.

The strategy reflects increasing pressure on African telecom operators to reduce diesel consumption, lower operating costs and improve resilience in markets where grid reliability remains weak.

Tower operators and mobile-network companies across the continent have accelerated renewable-energy deployment in recent years, including Helios Towers (LSE: HTWS), Safaricom (NSE: SCOM) and MTN Group (JSE: MTN).

Orange also partnered with the Congolese subsidiary of Vodacom Group (JSE: VOD) in 2025 to share the cost of deploying solar-powered infrastructure in rural areas of the Democratic Republic of the Congo (DRC).

The operator had around 179mn customers across 18 countries in Africa and the Middle East at the end of 2025, with many of its largest operations concentrated in francophone African markets.
