Your Linky data soon at Amazon? Doubt sets in

Your Linky meter knows a lot about you. Not just the number of kilowatt hours burned in the month: with the “load curve”, a reading every thirty minutes, or even every ten, we reconstruct the course of your days.

The CNIL has made it clear since its deliberation no. 2012-404: this measurement step makes it possible to identify your times of getting up, going to bed and your periods of absence. A peak at 7 a.m. is a wake-up call. Flat consumption for several days is a vacation.

This data travels through a path that few people know about. The meter sends its readings via CPL (power line transmission), a technique that passes the signal through your own electrical wires to a neighborhood hub. From there, Orange’s 2G mobile network takes over to the Enedis servers. In short: your consumption data already passes through a private operator listed on the stock exchange before even arriving at its destination.

Cloud Act: why Amazon is a problem

That's where it gets stuck. In April 2025, AFP reported that an Enedis information systems executive spoke, on condition of anonymity, of migrating some of the applications to the Amazon cloud, in the name of progress in artificial intelligence. In its official response to AFP, Enedis confirms that it is studying the movement of certain “non-strategic” applications while swearing that sovereignty remains an “essential” criterion. Except that since 2024, the company has been increasing job offers for AWS architects and cyber experts on AWS and Azure. Funny way to defend sovereignty.

This article largely takes up information from a file published by Clubic, which was the first to compile Enedis' AWS job offers, the anonymous declaration reported by AFP and the perspective with decree no. 2026-339. The editorial team must, before publication, either carry out its own verification of the job offers and the response from Enedis, or explicitly credit the original source.

The problem is that Amazon and Microsoft are American companies, therefore subject to the Cloud Act. This 2018 law allows American authorities to demand, by court order, data hosted by an American company, even stored on servers in France.

Only the SecNumCloud qualification, delivered by ANSSI, guarantees immunity to these requests. OVHcloud, Scaleway or Outscale have it. Neither Amazon nor Microsoft. And the timing raises questions: decree no. 2026-339 of April 30, 2026 now authorizes Enedis to collect the load curve of a sample of customers with the Base option at 6 kVA without obtaining their consent, to test price signals.

There remains one point of context: this decree of April 2026 does not come out of nowhere. As early as February 2026, the Energy Regulatory Commission (CRE), in a prospective report, openly raised the question of the end of prior consent, noting that only 30% of meters had activated the collection of the load curve, with most subscribers refusing not out of principle, but out of inertia.

The problem is not that Enedis necessarily lies, it is that we cannot verify anything: neither the location of the data centers nor the cloud providers involved are public. Be careful not to mix everything up: the ANSSI certification of the Linky chain only covers the encrypted transport of data, from the meter to the entrance to the information system, not accommodation on arrival. For data deemed sensitive by the CNIL and concerning 38 million households, it is a blind spot which deserves better than a reassuring press release.
