Electricity connection rates

You need an electricity connection to connect to the electricity network, for the network to extend to the border of your plot, and to use an electric meter.

Your connection fee covers the costs incurred from the construction of medium or low voltage networks and secondary substations up to the connection point of the distribution network. The connection point is determined in the connection contract, and is usually located on the border of the plot or construction site.

Other factors affecting the connection price include the main fuse size and the connection zone, i.e. the distance to the nearest secondary substation.

Please see below for information on how connection zones are determined. For electricity connection prices, see the rates at the bottom of this page. Choose your rates according to the network area where your metering point is located: Caruna Oy or Caruna Espoo Oy.

Delivery times when you receive a connection quote

Our Customer Service department can give you a connection quote over the phone for most of the areas where a zone rate has been set.

If we require further information about your site, however, you will normally receive a quote within a month. For example, we may need information on the connections, medium voltage connections, and industrial connections located outside the zones or situations where long sections of the network must be strengthened.


We use the so-called zone pricing to set the electricity connection rates. A connection zone is determined by the distance to the nearest secondary substation.

More information about the zones

Zone 1 Areas with a city plan and connections with a directly measured distance from an existing secondary substation of up to 300 metres. On shore plan areas, the zone pricing is based on distance.
Zone 2 Connections with a directly measured distance from an existing secondary substation from 300–600 metres.
Zone 3 Connections with a directly measured distance from an existing secondary substation from 600–800 metres. Main fuse size max. 3x35 A.
Area outside the zones Area or case-specific pricing, where the connection fee consists of direct network expansion costs and a capacity reservation fee.

Fixed term connection distribution rate

A fixed-term electricity connection is suitable for temporary electricity use, such as electrification of the construction site or during construction. The contract is concluded for a maximum of two years at a time.

We charge for the connection in accordance with our service rates, the basic fee and the power fee for the network service product will be doubled.
