If an existing electricity meter is being replaced by a digital electricity meter, we will notify you in writing as soon as possible. If the proposed date does not suit you, please contact us: 081 837 59 10

If free access to the meter is guaranteed, nobody needs to be at home. During the meter change, there will be a power interruption lasting about 15 minutes. You should therefore switch off electronic devices such as servers, computers or TVs beforehand and disconnect them from the mains.

The costs for the smart meter are borne by St. Moritz Energie. 

After the meter has been installed, your smart meter still needs to be integrated into our communication network. From this point onwards, you can view your own energy consumption and energy costs in the energy portal at any time.

All distribution grid operators in Switzerland are obliged under Art. 17a Para. 2 Electricity Supply Act and Art. 31e Para. 3 Electricity Supply Act to introduce an intelligent metering system and thus install smart meters. The change is a legal requirement of Energy Strategy 2050.

Yes, your data will be treated confidentially and will not be passed on to third parties. We adhere to the data protection guidelines in connection with smart electricity meters that are set out in the Electricity Supply Ordinance (StromVV). The components of a smart metering system (hardware and software) must fulfil strict data security requirements. Compliance with these requirements is checked by the Swiss Federal Institute of Metrology METAS and confirmed by means of certification. You can additionally protect your data by activating two-factor authentication. The transmission of data is encrypted and pseudonymised so that it is not possible to draw any direct conclusions about the customer. St. Moritz Energie may only process your data in a non-pseudonymised form for billing purposes. Data from smart meters that is not required for billing and is older than 12 months will be deleted or anonymised.

No. Real-time data acquisition is not provided. The data collected are 15-minute average values. These are transmitted with the number of your device and the current consumption and feed-in values (pseudonymised data). St. Moritz Energie also strictly adheres to data protection regulations.

The data belongs to the customer. It is only used for billing purposes and in pseudonymised form for the optimal management of the electricity grids.

As a distribution grid operator, St. Moritz Energie is responsible for metering in its grids in accordance with Art. 8 of the Electricity Supply Ordinance (StromVV). It is its responsibility to determine which metering infrastructures and information processes are used for its customers. If a smart metering system cannot be installed because the end consumer, producer or storage operator refuses to use it, the grid operator may invoice the resulting additional metering costs individually from the time of refusal.

A smart meter is an electronic electricity meter. It measures electricity consumption and production and communicates this data in encrypted form to St. Moritz Energie and the end customer. Electricity consumption and production can be read with pinpoint accuracy using a smart meter. The smart meter is an important component of an intelligent electricity distribution grid (smart grid). Thanks to a smart meter, the utilisation of the existing grid infrastructure is improved and the cost-intensive expansion of power lines is kept to a minimum or avoided.

Synonym for smart meter

A smart metering system is a smart meter that sends and receives data digitally and is integrated into a communication network for remote transmission.

An iMRS is an iMS extended by the control functionality. This means that in addition to measurement, the iMRS also performs control and regulation tasks. See also ‘Why is ripple control switched off?’

• No more on-site meter readings necessary
• Accurate meter reading possible, e.g. when changing tenants or for a billing period
• No more invoices on account, as the actual consumption is billed directly
• The recorded data is made available in a customer portal.
• You can see your energy consumption and optimise it
• You can find large or hidden electricity consumers in your household easily and independently

The municipalities of St. Moritz and Celerina, which are supplied by St. Moritz Energie, are currently building a fibre optic network together with Swisscom. Part of this project is also the laying of a so-called building fibre. The SmartMeter then communicates with the billing system via this connection. This communication is extremely secure, exceptionally energy-efficient and absolutely radiation-free.

No. The iMG communicates via the fibre optic network and is therefore absolutely radiation-free.

St. Moritz Energie relies on the Quickline Energy system. In doing so, we are relying on a proven, open and professional solution that was developed for the Swiss market, fulfils all legal requirements and is already being used by various utilities.

The iMG records 15-minute values of your electricity consumption. St. Moritz Energie only records the meter readings (register values) periodically, whereby the daily values are differentiated according to high and low tariffs.

Multi-utility refers to all trades other than electricity. This includes water and heat. The smart meters used in the St. Moritz Energie supply area enable the connection of so-called multi-utility meters. This means that the meter readings of these meters can also be read and billed remotely. This connection is not planned as part of the current rollout.

All electricity meters in the St. Moritz Energie supply area will be replaced by smart meters by 2027. You do not have to do anything for the meter replacement. It is the responsibility of St. Moritz Energie to decide which areas in the distribution grid will be upgraded and when. This is important to ensure an efficient rollout. A smart meter can therefore not be ordered by the customer.

The wires from your residential unit to the electricity meter must not be live during the changeover, as there is a danger to life. To ensure that appliances can be replaced in the future without being energised, we install so-called meter plug-in terminals during the installation of the iMG. This means that any future meter changes can be carried out without interruption.

The costs for your iMG are chargeable grid costs, i.e. there are no additional charges for you. Only if your electricity distribution system does not meet the technical requirements is the owner responsible for the corresponding preparatory work (see e.g. asbestos).

You will be informed personally about the exact time of installation and commissioning.

The rollout involves the gradual replacement of smart meters. St. Moritz Energie will replace around 10'000 meters with smart meters within around 3 years.

You will be informed via the press, social media and the St. Moritz Energie website. If you have specific questions about the smart meters, please contact us via our customer service. From 1 January 2025, St. Moritz Energie will install an iMG in all new buildings and conversions.

As a distribution grid operator, St. Moritz Energie is responsible for metering in its grids in accordance with Art. 8 of the Electricity Supply Ordinance (StromVV). It is its responsibility to determine which metering infrastructures and information processes are used for its customers. If an intelligent metering system cannot be installed because the end consumer, producer or storage operator refuses to use it, St. Moritz Energie may invoice the resulting additional metering costs individually from the time of refusal.

As soon as your circuit is equipped with an iMG and communication is stable, your consumption data is read out every 15 minutes. Once the data has been recorded for an entire month, it is available for you to view on the St. Moritz Energie portal.

On the main page of St.Moritz Energie at www.stmoritz-energie.ch you can register for the first time or log in as usual.

You can view your consumption data retrospectively via the customer portal. Furthermore, the Swiss Electricity Supply Act requires smart meters to have a customer interface, so that end users can access their meter readings ‘as soon as they are recorded’. To use this feature, additional adapters, dongles or smart home systems are usually required to visualise and control the data. Further information on the customer interface for electricity meters can be found at https://www.smart-metering-interface.ch/

No, with the introduction of the iMRS system at St. Moritz Energie, the ripple control system will gradually be decommissioned. All customers who currently have an application that is controlled via ripple control will be migrated to the new system. The prerequisite for this is the consent of the customer so that these so-called flexibilities can continue to be controlled.

No, the switching times remain the same. More flexible switching times will be introduced at a later date. However, St. Moritz Energie is endeavouring to transfer only those systems that are connected to the ripple control system to the new system, provided that the customer still wishes this and agrees to it.

Control using ripple control signals is an old technology that is no longer state of the art. Thanks to the rollout of our intelligent measurement and control system, we will be able to control loads much more precisely and therefore more efficiently in future.

According to Art. 8c of the Electricity Supply Ordinance, the energy supply company may only continue to control grid-serving loads after the RS system has been replaced with the customer's consent. Without consent, the energy supply company may only control loads in the event of imminent grid overload. This means that you will be able to control your loads freely in future. With all the advantages and disadvantages.

In the event of an imminent grid overload, an energy supply company may switch off loads as an emergency measure. This is sometimes done on a ‘larger scale’ by switching off entire consumers. To prevent this, an energy supply company needs the largest possible manipulation mass that can be switched on or off without major consequences.
Heat applications (boilers, storage heaters, etc.) but also charging stations and heat pumps are generally very suitable for this purpose.

Do gutter heating systems prevent uncontrolled icing of pipes? This icing depends on local factors. General control of such systems is difficult and can lead to damage. Individual on-site control is much safer for this application. However, gutter heating systems can also be switched off without prior notice to prevent an imminent grid overload.

Asbestos refers to a group of mineral fibres that can also be found in certain rocks in Switzerland. For a long time, asbestos was regarded as a ‘miracle fibre’ for industry and construction, as it is very heat-resistant and has a high electrical insulating capacity, among other things. Asbestos fibres are also very elastic and tensile. They can therefore be easily incorporated into various binders. Products containing asbestos were also used in buildings for electrical installations, among other things. Even though asbestos has been banned in Switzerland since 1990, it can still be found in many places.

Asbestos should not be inhaled. If building materials containing asbestos are mechanically processed, the fibres split into smaller and smaller fibres, which are quickly dispersed over a wide area in the air. If they are inhaled, they can become lodged in the lungs or pleura. There, asbestos fibres can lead to various diseases. These include, in particular, asbestos lung and lung or pleural cancer. For all asbestos-related diseases, the time between exposure to asbestos and the onset of the disease is long: usually 15 to 45 years elapse. The longer and more intensively a person is exposed to asbestos fibres, the greater the risk of illness. In order to avoid illness, building materials containing asbestos must be recognised in good time. Only then can the necessary protective measures be taken to prevent the fibres from becoming airborne or being inhaled.

In many buildings that were built or last renovated before the asbestos ban (or before the transitional periods expired), electricity meters are mounted on meter boards containing asbestos. As long as meter boards containing asbestos are not mechanically processed, they do not generally pose an immediate risk to residents. A health hazard only arises when asbestos fibres are released and inhaled. When replacing electricity meters on meter boards containing asbestos, it is possible for asbestos fibres to be released into the air. St. Moritz Energie replaces its electricity meters in accordance with the legal requirements. Our employees or their authorised representatives are trained to recognise asbestos and to assess the danger it poses. Based on the risk assessment carried out, our employees carry out the work in accordance with the protective measures specified by the Swiss Accident Insurance Fund (Suva). St. Moritz Energie prioritises the health and protection of its employees, partners and customers. We therefore recommend that you remove building materials containing asbestos, such as meter boards. This applies in particular if changes are made to the electrical installations due to conversions or renovations.

The fitters of St. Moritz Energie will not carry out the meter change (see previous question). The customer will then be contacted by St. Moritz Energie.

The home distribution system is the property of the homeowner and is their responsibility. You therefore decide on the replacement. St. Moritz Energie strongly recommends replacing distribution boards containing asbestos. If a smart meter cannot be installed, St. Moritz Energie will charge for the additional cost of manually reading the electricity meter.
