Siemens led a consortium with Landis+Gyr and Iskraemeco (selected 2017) to swap Vienna-area electricity meters for smart meters from November 2018. Wiener Netze hit Austria's 95% legal target in December 2024 and had cut remaining legacy meters to about 46,000 of ~1.6 million by March 2026; consumption data is available to customers the following day.

Live 📅 since 2018

📊 Impact

~1.6 million electricity meters in Wiener Netze's service area; Austria's 95% legal smart-meter target reached in December 2024, with about 46,000 legacy meters still outstanding by March 2026 against roughly 1.6 million exchanged; Austria's national rate stood at 96.9% at the end of 2024 per regulator E-Control.

🎓 Lesson

Installing the meters was only half the job: in 2026 Wiener Netze was still chasing about 46,000 hold-outs it can ultimately reach only through a power cut-off or a lawsuit, and nationally only 12.6% of households had switched on quarter-hourly readings — the setting Wiener Netze's 2026 summer grid-fee discount requires.

Claim 1 clm-0b0916d3a0d917e6 quantitative
Siemens led a consortium with Landis+Gyr and Iskraemeco (selected 2017)
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Iskraemeco's project page dates the award and names the same three companies: "In August 2017, Wiener Netze announced that it had selected a consortium comprising Siemens, Landis+Gyr and Iskraemeco for the mass-deployment phase of the rollout." Siemens' own magazine names the same three: "Siemens ist gemeinsam mit Landis+Gyr und Iskraemeco Lead- und Technologiepartner der Wiener Netze bei der Umstellung auf die neuen elektronischen Stromzähler" (Siemens is, together with Landis+Gyr and Iskraemeco, lead and technology partner of Wiener Netze).
Caveat
Neither source puts Siemens above the other two. Iskraemeco describes a consortium of three without a lead, and the Siemens magazine calls all three jointly lead and technology partners, so "Siemens led" is a stronger reading than the sources give. Both are suppliers writing about their own contract.

to swap Vienna-area electricity meters for smart meters from November 2018
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Iskraemeco gives the month: "Installations began at a smaller scale in November 2018." The Siemens magazine gives the year and the scope: "Im Jahr 2018 starteten die Wiener Netze mit dem Tausch bei rund 1,6 Millionen Haushalten und Unternehmen" (in 2018 Wiener Netze began the swap across some 1.6 million households and businesses).
Caveat
November 2018 was a deliberately small start. The same source says the large-scale phase only began in 2021, with 436,000 meters deployed by the end of that year. The service area is also wider than the city: Wiener Netze supplies Vienna plus parts of Lower Austria and Burgenland.

Claim 3 clm-26a02673e3a44f91 quantitative
Wiener Netze hit Austria's 95% legal target in December 2024
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Siemens' magazine ties the milestone to a dated, symbolic meter swap: "Mit dem symbolträchtigen Tausch der Zähler im Wiener Stephansdom im Dezember 2024 haben die Wiener Netze 95 Prozent aller Stromzähler auf neue elektronische Stromzähler umgestellt" (with the symbolic meter swap in St Stephen's Cathedral in December 2024, Wiener Netze converted 95 percent of all electricity meters). Wiener Netze's own legal page dates the same achievement a month earlier, to November 2024: "Dieses Ziel haben die Wiener Netze im November 2024 erfüllt." The operator and its supplier therefore give different months for the same milestone.
Caveat
The month is disputed by the operator itself. Wiener Netze's legal page says the target was met in November 2024; the December date comes from its supplier and is tied to a symbolic ceremony rather than to the moment the threshold was crossed.

Claim 4 clm-6c9acccf8ea63d4e quantitative
cut remaining legacy meters to about 46,000
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Both the operator's press page and the identical wire release state the figure: "Bereits rund 1,6 Millionen Smart Meter sind installiert. Aber rund 46.000 Altzähler sind noch im Einsatz" (some 1.6 million smart meters are installed, but around 46,000 old meters are still in service). The release adds why they must go: the calibration period of those meters is expiring, and under the Austrian weights and measures act they may then no longer be operated.
Caveat
This is the operator's own count and is not broken down or independently audited. The release is also an enforcement notice, which gives Wiener Netze a reason to state the remaining number plainly.

Claim 5 clm-6aff12715b58be2c quantitative
of ~1.6 million
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The press release counts the meters already exchanged: "Mehr als 1,6 Millionen Zähler wurden bereits erfolgreich getauscht" (more than 1.6 million meters have already been successfully exchanged). Siemens' magazine uses the same order of magnitude for the whole task: "Im Jahr 2018 starteten die Wiener Netze mit dem Tausch bei rund 1,6 Millionen Haushalten und Unternehmen."
Caveat
The two sources count slightly different things. The press release puts about 1.6 million meters already swapped and roughly 46,000 still outstanding on top of that, so the total stock is a little above 1.6 million rather than 46,000 being part of it.

Both carry the same date line for the statement of remaining meters: the operator's press page is marked "Publiziert am: 30.03.2026" and the wire release is stamped "30.03.2026, 10:00:50". The figures are given as the position on that day.

~1.6 million electricity meters in Wiener Netze's service area
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The press release states the installed base and the service area in the same document: "Bereits rund 1,6 Millionen Smart Meter sind installiert", and separately that "Mehr als 2 Millionen KundInnen in Wien, Teilen Niederösterreichs und des Burgenlands" are supplied (more than 2 million customers in Vienna, parts of Lower Austria and Burgenland). Siemens' magazine gives the same 1.6 million figure for the households and businesses covered by the swap.
Caveat
The figure counts electricity meters, not customers: the same release puts the customer base above two million. It is an operator figure and carries no independent count.

Claim 8 clm-36154b0f178a12e6 quantitative
Austria's 95% legal smart-meter target
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The operator's legal page describes the quota as a national one, set out in a regulation under the Austrian electricity act: "Der nationale Plan für die Einführung sieht zu den Zielen auf EU-Ebene bis Ende 2024 eine Abdeckung von mindestens 95 Prozent der österreichischen Haushalte und Unternehmen mit Smart Metern vor" (the national rollout plan provides for coverage of at least 95 percent of Austrian households and businesses by the end of 2024). The page names the instrument as the Intelligente Messgeräte-Einführungsverordnung (IME-VO 2022) under ElWOG 2010, and traces the requirement back to the EU's third internal energy market package.
Caveat
The 95 percent is a country-wide quota, not a target written for Vienna. Wiener Netze reports meeting it within its own service area; the page does not say what share of the national total that represents.

Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Siemens' magazine, published on 19 December 2024, reports the threshold as crossed that month: "Mit dem symbolträchtigen Tausch der Zähler im Wiener Stephansdom im Dezember 2024 haben die Wiener Netze 95 Prozent aller Stromzähler auf neue elektronische Stromzähler umgestellt." Wiener Netze's own legal page instead says the target was met in November 2024: "Dieses Ziel haben die Wiener Netze im November 2024 erfüllt."
Caveat
The operator dates the same milestone to November 2024, a month earlier than this entry states. The December date rests on a supplier publication and on a ceremonial meter swap.

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The operator's press page of 30 March 2026 states the outstanding stock and the reason it must go: "Bei rund 46.000 – noch nicht getauschten – Zählern läuft die Eichfrist ab" (the calibration period is expiring on around 46,000 meters not yet exchanged), and meters that fall outside calibration rules may no longer be operated under the Austrian weights and measures act.
Caveat
An operator figure with no independent verification, published as part of an enforcement notice warning the last holdouts of disconnection or legal action.

Austria's national rate stood at 96.9% at the end of 2024 per regulator E-Control
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The trade report is titled "Österreich erreicht nahezu Voll-Rollout bei Smart Metern" (Austria reaches near-complete smart meter rollout) and attributes the share to the regulator E-Control, which counts metering points rather than customers. The article itself could not be opened: every edition of the publisher's site answers automated requests with a block page, so the wording was confirmed through search results rather than read on the page, and no locator string could be taken from it.
Caveat
The national figure counts metering points across Austria and is published by the regulator, not by Wiener Netze. The Vienna share it is compared against is not published by the operator at all, so the two numbers are alike in size but are not measured the same way. The reference year could not be confirmed on the page itself.
