The power line and telecom network installation market in France

RTE plans around €100 billion of investment over fifteen years, to 2040, in its ten-year network development plan (SDDR) published in 2025. Connections of consumers and low-carbon generation account for €53 billion, renewal and climate adaptation for €24 billion, and reinforcement of the extra-high-voltage grid for €16.5 billion. This programme durably supports the power line and telecom network installation market in France.

According to RTE’s SDDR, 23,500 kilometres of lines, 85,000 pylons and the telecom and control-command system will be renewed across France in the plan running to 2040. This renewal and climate-change adaptation component is estimated at around €24 billion. It responds to ageing infrastructure and feeds a significant share of the demand addressed to power line companies in France.

According to the Autorité de régulation des communications électroniques, des postes et de la distribution de la presse (Arcep, the French telecoms regulator), 28.1 million fixed internet subscriptions use optical fibre in France at the end of June 2026, or 85% of the total. The number of very-high-speed connections keeps rising. After the mass construction phase, the telecom network market in France is turning to final connections and maintenance.

Orange announced at the end of 2019 the technical shutdown of its copper network in France. According to Arcep, the timetable, organised in batches of municipalities, began to apply from 2023 and provides for completion in 2030. The shutdown accompanies the spread of optical fibre and opens up, for the power line and telecom network installation market in France, work on migrating the last customers and removing old infrastructure.

The power line and telecom network installation market in France brings together subsidiaries of large electrical engineering groups and regional public works companies. In telecoms, Circet presents itself as the leading European telecom infrastructure services group, with €4.912 billion of pro forma turnover in 2025; its website attributes €1,041.8 million of turnover and 2,954 employees to France.
