To make your daily life run smoothly, we at Caruna make sure that you have uninterrupted access to electricity. 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). The work began with the medium-voltage overhead cables in forests and sparsely populated areas with the greatest residential density and amounts of electricity transferred. Now, we are also renewing the electricity network in neighbourhoods close to densely populated centres. 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.

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).

  • 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 safer

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 – you can check and update your contact information in Caruna+.

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

We answer your questions on our social media channels on weekdays from 8 am to 4 pm:


Chat with an expert

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. We serve coffee and snacks! If you did 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.

We build and develop our electricity network ever closer to our customers, which is why we want to be present ourselves. Our resident service tours the population centres of Southwest Finland 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.

If you would like to discuss a specific project with us or other concerns, just come and see our resident service.

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. The remaining pole-mounted transformers in the restructuring programme will be dismantled in the spring and winter of 2020.

Our responsibility also includes employee responsibility, and we invest in developing the occupational safety of our subcontractors. At the start of the year, we launched electrical and occupational safety training for non-electrical professionals. More than 1,100 subcontractors have completed the Caruna Card training.

Joint fibre optics construction

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.

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.

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.
