Metering
Metering installation and alteration work must always be ordered by an electrical professional.
Remotely readable meters
In connections and cuts of electricity related to the start and termination of electricity contracts, electricity can be switched on or off remotely. Electricity is connected and disconnected automatically according to the validity periods of the electricity contracts. If you have a contract that has started and you have received an SMS about connecting electricity, follow the instructions behind the link below.
Replacement of meters
We started the extensive renewal of meters in 2023, and nearly all current meters will be replaced by the end of 2029. The technical service life of electricity meters is approximately 15 years, and the replacement has started with the oldest meters. By the end of 2024, approximately 120,000 meters will be replaced across Helsinki, and approximately 240,000 meters will be replaced during 2026–2028. There may be meters of different ages in the same property, so not all meters are necessarily replaced at the same time.
Information on meter replacements
The residents of the areas are informed of the replacement of meters as the replacement process progresses. Meter replacements are carried out by our partner Eltel Networks. If the electricity meter is located in your home, Eltel Networks will agree with you on the time of installation. If the electricity meters are located in the housing company’s public premises, Eltel Networks will inform you of the meter replacement by letter and SMS. We recommend that you follow Eltel Networks’ announcements about the replacement of meters and act according to Eltel’s instructions.
Replacing the meter is a simple procedure and the installation visit takes about half an hour. The meter replacement causes a short power outage.
To ensure a smooth replacement of the meter, please make sure that there is enough free space in front of the meter for the electrician to work safely. It is also necessary to make sure that the property's access information and the contract person’s mobile phone number are up to date. If an individual meter is not replaced, such as in an apartment building, the metering data of this meter will probably need to be estimated when the remote reading connection is lost.

Reading instructions for device types
A relay installed in the meter is available for controlling electric heating, such as at delivery sites with time-based distribution as the distribution product. The load controls are switched on with a random delay between 10 p.m. and 11 p.m. and switched off at 7 a.m. However, the night-time distribution price of time-based distribution starts at 10 p.m.
The smart electricity network benefits electricity users and helps to build readiness for renewable energy solutions. The new generation of electricity meters provides even more real-time information about your own electricity consumption. Via the HAN (Home Area Network) home automation connection located in the meter cover, you can use a data package updated every 10 seconds to optimise, for example, the charging of electric cars.
There is an RJ-12 connector on the meter cover to which you can connect your own device to receive data. The HAN port is activated by Helen Electricity Network, after which data is sent out from the gate in 10-second cycles. Activation of the interface is free of charge.
Below you can read Sesko’s recommendation for the local H1 customer interface for electricity meters and check the list of data sent. You can use the contact form to request activation of the HAN port.
Contact form for port activation
Meters with HAN ports have been installed since the beginning of 2023 and all meters will be equipped with HAN ports by the end of 2030. You will receive a meter with a HAN port free of charge in connection with meter replacements carried out by Helen Electricity Network. If you want a meter with a HAN port earlier, please contact us via the contact form. In this case, we will charge a fee in accordance with the service price list for the replacement of the meter.
