We are building a weatherproof electricity network

Sometimes, when the weather surprises us, the electricity is cut off. These are the unexpected situations that we are trying to reduce by revamping the electricity network. We will improve electricity distribution by moving the electricity network underground. There, the network is protected from the weather and the number of power outages is reduced.

To date, 56% of our electricity network has been moved underground (Caruna Oy and Caruna Espoo Oy). We are renewing the electricity network both in urban areas as well as in sparsely populated areas. You can check the building sites in your neighbourhood on our map service.

We take care of our network in many more ways. Tree tops and branches growing near to power lines will no longer fall on the lines in windy weather and cut off electricity.

Building site ahead, please be careful

Please bear safety in mind when you are near the building site.

  • Do not touch power lines that are hanging down on the ground, as they may still be live.
  • Please do not remove the markers indicating building materials or excavation routes
  • If you need to move cable reels or other materials, please let us know by contacting our customer service

Temporary passageways or detours are built to make the area safer for you.

This is how the construction proceeds

The construction of the electricity network takes about one to two years and consists of several stages, only some of which are visible to the residents in their daily lives.

  • Caruna orders the project from a contractor.
  • We are beginning to design the electricity network, and this will take about six months, depending on the area.
  • Once the design has been completed, we will begin building the new electricity network. The duration of construction is affected by, among other things, terrain conditions and weather (for example, frost in spring).
  • After commissioning, the old electricity network will be dismantled and finishing work will begin. During the finishing work, the electrical network material is removed from the area. The gardens and streets will be tidied up to at least the condition they were in when the project started.
  • Finally, we will carry out the relevant inspections. For example, we will check that the new electricity network has been installed to at least the depth required by standards (70 cm below ground level).

Information and customer service

We will communicate the construction phases by means such as text messages

The dismantling of the old electricity network or the commissioning of a new electricity network may cause short interruptions in the electricity distribution, of which we will inform you in advance. Please make sure we have the correct contact information in the Caruna+ service.

You can track construction progress and timetables in our map service, where you can also subscribe to messages about the site in your area.

Quick answer from the chat service

You can chat with our service expert on our website on weekdays from 8 am to 4 pm. The chat box will appear on the bottom right when we are free to answer your questions.

At customer events, you can ask about construction

When we plan an electricity network improvement project, we organise a customer event for the residents of the area. Come and ask Caruna and its contractors about the project planning. If you can not make it, but you are interested, here’s a program of events.

Frequently asked questions

Take a look at our website for the most frequently asked questions about, among other things, the construction of the electricity network.

Resident service available

Our resident service tours the population centres to provide information on construction sites, listen to our customers' feedback and provide guidance on matters related to electricity distribution. Resident Service ensures that our customers are satisfied with our construction during all stages of the work. Resident service also provides guidance through the implementation of our services.

We are committed to responsible land use and safety

During construction, environmental impacts are minimised as much as possible or even made positive for the environment, landowners and other stakeholders.

We recycle 95% of dismantled materials from the electricity network. From 2016 to 2019, we removed approximately 1,150 pole-mounted transformers from groundwater areas. 

Our responsibility also includes employee responsibility, and we invest in developing the occupational safety of our subcontractors. We have launched electrical and occupational safety training for non-electrical professionals. Already more than 1,500 subcontractors have completed the Caruna Card training.

We are committed to safety and responsible land use.

We construct our electricity network together with other operators whenever possible. Joint construction of the electricity network is a sensible option for the environment and for citizens: at best, it can spare local residents from repeated disruption due to excavation work and reduce the burden on the environment.

We build with other operators whenever possible.

Modern society is based on high-quality telecommunications connections, extensive use of information technology and secure access to electricity

Joint construction also enables us to ensure that more areas with small houses are included, and that work is done in a more environmentally friendly way. Fibre optics provides faster internet connections, which can offer data transfer rates of up to 1,000 Mbps, enabling the best possible digital services.

Fibre optics enables residents and companies in an area to begin using all of the newest internet, television, video, communications and health services.

Contact Valokuitunen if you are interested in a modern and reliable internet connection

Caruna is building a fibre optics network in the Southwest Finland region in partnership with Valokuitunen. If you live in this area, you will be able to obtain a fixed network connection when we put the electricity network underground.

The Caruna contractor is responsible for the design, construction and installation of the fibre optic network excavation route. The construction work that will be done on customers' sites and in their homes will be planned by Caruna's contractor.

Valokuitunen is responsible for selling the high-speed fibre optic connection built by Caruna. They will talk about acquiring a subscription in areas where fibre optics are being built. If fibre optics is available in your area, you will receive a letter or postcard from Valokuitunen with more information.
