The old power system in Tallinn
Some parts of Tallinn are still supplied by the 3 x 220 V power system, also known as the old power system. This low voltage network built in the 1930s–1960s mainly serves the Central, Kristiine, and North Tallinn city districts, and also buildings in the Old Town. We currently only repair breakdowns in this out-of-date system.
Mandatory connection
For most of the 840 buildings covered by the old system, nearly half of them, we have already built an electricity network with the new voltage system.
For places of consumption where the customer has received notice of the possibility to transfer to the new power system, the customer must connect to the new network within three (3) years.

The advantages of the new power system
Higher security of supply
The new power system allows electricity to be transferred to your place of consumption from different substations. This reduces the number of power outages significantly.
More power
It is possible to consume 1.7 times as much energy with the same main fuse as in the old power system.
Higher quality
The cross-sections of the new cables are larger and the network is built to a supply loop design.
Improved safety
The new voltage and an updated internal electricity system reduces the danger of electrical accidents and fires.
New opportunities
Solar panels can be connected to the new power system.
Who should connect to the new power system?
Customers whose houses and apartments are within the new power system network can already connect to the new system. A new connection must be established within three years after receiving notice from us.
How much does it cost?
Our services for switching to the new power system, including the installation of a junction box, new cable lines to the connection point and the replacement of the meters, are free for you. The required electrical works inside your house have to be carried out at your own expense.
The part of the internal electrical system of the building that is outside the apartments will have to be renovated at your expense. We also recommend all apartment owners update the electrical system inside their apartments.
Grants for renovating electrical installations
From April 2015 until 2026, grants are available from KredEx to renovate electrical systems. This means that you will pay up to 50% less to renovate the part of electrical system inside the building that is outside the apartments. You can read more about the grant for renovating electrical installations on the web page of KredEx »
Steps to switching to the new voltage system
If you live in an apartment building, a joint decision is needed to switch to the new voltage system. In a private home, the owner must make the decision.
Submitting an application
On the basis of your application we can prepare a technical inspection document and a connection quote.
Construction work in the external network
We will install a new input cable and replace the old meters.

The old power system in Tallinn
The cables used in the electricity network with the old voltage system have exceeded their optimal service life by now. It is an outdated network that poses significant electrical hazards and causes power outages.
Elektrilevi renews the network in the above-mentioned areas annually, building a network with a new voltage system next to the old network, thus creating an opportunity for consumers to connect their apartment building to the new electricity network.
When the network with the new voltage system is ready, the customers of the old voltage network in the same area will be notified. The customers will also be obliged to upgrade the in-house electricity system within the next three years. That must be done to be able to join a new voltage system that is significantly more reliable and safer than the old voltage system. If the connection to the new network does not take place within three years, the customer will be charged a fee for maintaining the old voltage system.
Who should connect to the new power system?
The obligation to transfer to the new power system arises from the Grid Code (§ 36 subsection 1) established with a government regulation.
The buildings that are still connected to the old system will be connected to the new network step by step. The new network will also be extended as planned to buildings that are not yet connected to it.
Steps to switching to the new voltage system
On the basis of your application we can prepare a technical inspection document and a connection quote.
Send us an application (pdf) to switch to the new voltage system. After receiving the application we will prepare and issue the technical inspection document and a connection quote within 5–30 days.
If the network with the new voltage system has not been extended to your building yet, we can most probably transfer your house to the new system within a year. If the transfer cannot be completed within a year for technical reasons, we will let you know.
We will install a new input cable and replace the old meters.
Arrange for the renovation of the internal electrical system of the building in the jointly used areas of the building and order the necessary measurements.
To bring internal electrical systems of the house up to date, you have to complete the following work:
