Electricity network connection fees

A connection fee is charged for connecting to the electricity distribution network in accordance with the price list.

The connection fee covers the construction costs of the distribution network up to the connection point. The distribution network includes medium- and low-voltage networks as well as distribution transformers. The connection fee also includes connection to the distribution network and the installation of a consumption meter.

Depending on the structure of the distribution network, the connection point can be a distribution cabinet, an underground cable on the border of the plot, an overhead trunk line or a distribution substation. Primarily, the connection point is located on the border of the plot.

The connection fee is refundable, and no value added tax (VAT) is charged. When the connection is dismantled, the connection fee will be refunded minus the cancellation costs. Previously defined connection or area prices will be processed in accordance with the agreed terms.

Below you will find the connection price list and principles in the distribution area of Nurmijärven Sähköverkko Oy.

Low-voltage connections

The connection fee for low-voltage connections is based on the size of the main fuse and the distance measured as beeline from the existing distribution substation. Zone pricing is used to determine the effect of distance. Zone pricing refers to the uniform division of low-voltage connections into different zones based on their geographical location. Nurmijärven Sähköverkko Oy has two zones in use.

Zone 1 covers the existing local detailed plan area. Zone 1 also includes junctions outside the local detailed plan area, which are located directly from the plot boundary at 200 m from the existing distribution substation.

Zone 2 is valid outside the local detailed plan area with junctions of up to 3x63A located at no more than 600 m from the existing distribution transformer substation. With fuses larger than this, the distance from the existing distribution substation is no more than 300 m.

Area pricing refers to the determination of the connection price of a certain pre-defined area that is not included in zone pricing. The area price is formed by dividing the construction costs of the estimated connections in the limited area subject to pricing by the number of potential connections in the area. However, when applying area pricing, the minimum price of the connection is the connection fee according to zone 2.

The capacity reservation fee for the low-voltage network is €48.30/kVA.

No VAT is charged on connection fees.

Medium- and high-voltage connections

In this context, a medium-voltage network refers to an electricity network with a voltage level of 20 kV and a high-voltage network refers to a 110 kV electricity network. The subscriber owns and pays for its transformer substation and is responsible for its use and related installations. In addition, the person joining must have their own manager for the use of electrical equipment.

In the medium and high-voltage network, the connection fee is based on two components: the connection, construction and other possible costs directly incurred by the network operator for connecting to the network, and the cost of capacity reservation:

Connection fee = a + b x P, where

a includes the direct network extension costs of connecting to the network and any network security costs resulting from the connection, but excludes the costs of strengthening the network [€],

b is the capacity reservation cost, which also covers the cost of strengthening the existing medium and high-voltage network [€/kVA], and

P is the connection power [kVA] of the connector.

When estimating construction costs, the unit prices used in the Energy Authority’s determination of the network value are used.

The capacity reservation fee for the medium-voltage network is €23.50/kVA
The capacity reservation fee for the high-voltage network is €10.10/kVA
No VAT is charged on connection fees.
