Grid connection regulations require grid operators that are directly connected to the transmission grid to ensure that there is available capacity in the transmission grid before allocating capacity to customers in their own grid. In order to streamline such clarifications, we ask grid operators to report sufficiently mature connection cases to Statnett in batches, so we can clarify whether the increased exchange at the connection point is operationally viable. The grid agreement must be updated before capacity is increased at the connection point.

For the processing of connection cases, the country is divided into areas that are managed by designated contact persons. We follow up on connection cases and grid agreements. You can contact us for guidance and follow-up. At the bottom of this page, you can find contact information for the different parts of the country.

Grid operators that are directly connected to the transmission grid must use the following process to clear their current and future capacity needs with Statnett:

Grid operators must report how much capacity is needed for general consumption growth

Individual customers with consumption below 1 MW are regarded as ordinary consumption when we consider the need for increased capacity. This also applies in cases where the sum of several small connections, such as the development of residential or cottage areas, exceeds 1 MW in total. Although connections below 1 MW do not need to be reported as connection cases, we need grid operators to regularly share updated forecasts for general consumption growth with Statnett, together with other known plans for increased consumption or production that will increase the load at the connection point.

It is the grid operator’s responsibility to ensure that forecasts for consumption development in its own grid are updated and as reliable as possible. Several factors must be considered, including coincidence factor, how consumption growth is distributed among different connection points and limitations in the regional grid. Grid operators must themselves assess how much capacity (power volume in MW) must be reserved for general consumption growth at their connection points with the transmission grid.

Statnett plans development of the transmission grid based on the grid operator’s forecasts, and we strive to have processes that ensure the best possible accuracy to meet consumption growth in a timely manner. This means that the grid agreement’s capacity limit will include volume for general consumption growth, provided that it is operationally viable. As a general rule, capacity is reserved for growth for four years, with a new assessment every other year, coordinated with the Regional Power System Assessment (RKSU) process. If there are limitations in the transmission grid, Statnett will reserve the expected volume, within the time horizon until the necessary grid measures are in place.

Requests for increased capacity for larger individual customers must be sent to Statnett for an individual assessment

Grid operators must clarify the capacity of the transmission grid before they connect new consumption or production in their own grid. Until the spring of 2022, we have processed and reserved capacity related to each individual case submitted by grid operators.

Statnett reserves volume at the individual connection point, which the grid operator in turn distributes to its own customers. In this context, volume will constitute the grid operator’s assessment of the expected increase in maximum consumption or input at the connection point in the transmission grid (cf. grid agreement), and not the sum of installed power from each individual customer.

Grid operators must clear the connection of new customers with installed power greater than 1 MW with Statnett. The same applies in the event of a need for increased capacity exceeding 1 MW for the grid operator’s existing customers. The connection manager will work with grid operators in assessing which cases must be clarified with Statnett.

In order to deal with the demand efficiently, grid operators that have several connection cases over 1 MW, which affect the exchange at the same connection point, must pack these into a total volume that is expected to comprise the increased exchange with the transmission grid. It is also possible to take into account expected future cases. The grid operator itself must assess how the connection affects the maximum power exchange (MW) from the individual connection point and state this in the application form. You can find a link to the application form at the bottom of this page.

Please submit requests for increased capacity for connection cases with power requirements greater than 1 MW in the form at the bottom of this page.

The grid operator must decide whether the cases require guidance or whether they are specific requests for increased transmission capacity, cf. the corresponding process for our direct customers. The grid operator must note this in the form.

When submitting the application form, the grid operator must inform Statnett of the operational viability assessments in the regional grid and the local grid, if applicable. The grid operator must state whether the requested volume will require grid reinforcements in the regional grid or possibly the local grid. Furthermore, the grid operator must state whether there will be congestion in the event of an intact grid or operational stoppage, and how the grid operator will handle such situations.

The grid operator must assess the maturity of requests for capacity in its own grid. In larger cases, it is appropriate for Statnett and the grid operator to make a joint maturity assessment. For individual cases over 100 MW, Statnett and the grid operator must always jointly assess the maturity of the project.

When the grid operator considers its customer’s need for connection or increased capacity to be sufficiently mature, and the grid operator has carried out an operational viability assessment in its own grid, the grid operator may submit a request to Statnett for increased capacity in the transmission grid. You will receive confirmation that your request has been received within 14 days. The confirmation will include an estimated response time for the request.

Statnett assesses capacity in the transmission grid

When the grid operator requests increased capacity for projects or needs that are sufficiently mature, Statnett makes an assessment of whether there is available capacity in the transmission grid and whether the increased power exchange is operationally viable.

All major requests for increased capacity are handled in Statnett’s work with the relevant area plan. This will provide a more holistic perspective on operational viability assessments and an overall more efficient process for meeting demand.

If the customer’s power requirements and location have not been reasonably clarified, Statnett may require compensation for clarifying whether it is operationally viable to comply with the customer’s request. The payment is determined on the basis of actual expenses incurred.

Statnett reserves capacity for mature needs

In order for Statnett to reserve available capacity, it must be reserved by grid operators or direct customers. In addition, grid operators must assess how much capacity must be reserved for general consumption growth. Reservations are assessed on the basis of an application/order, based on specific maturity criteria. The available capacity is not reserved, which means that other grid operators or direct customers can also order the available capacity. We therefore ask you to order capacity as soon as possible after our response, if your customer(s) proceed with their plans.

In order for Statnett to reserve capacity for the grid operator, the grid operator must have made an updated maturity assessment of the volume that is the basis for the order. Statnett must be provided with a written summary and conclusion of the assessment.

To ensure a fair and transparent distribution of available capacity in cases where capacity in the transmission grid is limiting for several grid operators and/or Statnett’s direct customers, the grid operators and Statnett must jointly consider queues of connection cases according to principles that are as similar as possible. Statnett’s general principles and criteria for assessing the maturity of projects that order capacity are described in our process for direct customers.

If there is no available capacity, Statnett will consider measures for increased capacity

Statnett prepares area plans for grid development in all regions as a basis for our comprehensive grid and system development. As a result, we will be able to see system measures and installation measures in context, and bring together the needs for market measures, refurbishment, grid capacity and maintenance. The area plan for a given area is updated every two years.

If there is no available capacity to connect the requested volume in the existing or planned grid, we will study the need for new measures in the transmission grid in the relevant area plan. Before each update of the area plan, we require updated information from the grid operator about the requested capacity in the relevant area, including an updated maturity assessment. The area plan will identify the measures that make it operationally viable to connect mature needs.

Statnett will not normally enter into assessment agreements with customers before the start of the development project, as this is handled through the work with the area plans. Making an overall assessment in an area plan means that some cases will have to wait, but carrying out such assessments from a more holistic perspective enables us to limit the time spent on each individual case.

After the area plan has identified the necessary measures to connect the requested capacity, the grid operator can place an order based on which needs are mature and most likely to be realised. The same guidelines apply here as when ordering available capacity (see above).

The table below shows examples of the time required to implement measures after they have been identified through our work with the area plan. Lead times will vary from case to case.


Design and implement measures* 

Increased transformer capacity 

4–6 years 

New substation 

5–10 years 

New power line 

7–12 years 


*Median values from the start of the project until the facilities are in operation, including time to secure statutory permits. Lead times for new grid facilities will vary between projects of the same category. The main reasons for these variations are scope of work, need for disconnections and time required for licensing processes. Interfaces to other projects, access to materials, geographic location, topography and seasonal work are also factors that often affect lead times.

In accordance with statutory regulations, Statnett is in some cases obliged to require investment contributions for measures in the transmission grid from customers in the underlying grid. When Statnett initiates a grid development project, we will enter into an agreement on coordinated project development. The customer will then have to pay a share of the project development costs for the measures in the transmission grid.

Connection with conditions that stipulate terms for disconnection or limitations in consumption or production may be considered

If there is no available capacity in the transmission grid on ordinary terms, we may consider providing a connection with conditions that stipulate terms for disconnection or limitations in consumption or production, if this is operationally viable and desirable for the end customer, cf. section 3-2 or 3-3 of the Norwegian regulations concerning grid operations and the power market (NEM). Such terms are voluntary for all parties and facilitate faster connection to the grid. In accordance with the regulations, customers are not entitled to any form of compensation when entering into such an agreement or when disconnecting or limiting consumption or production. The grid operator and Statnett will make a joint assessment of any connections with such terms.

Grid operators must follow up on their own customers prior to connection and report to Statnett on actual capacity utilisation

It is the grid operator’s responsibility to set deadlines for its customers until operational start-up, and further for utilisation of reserved capacity.

If the grid operator cancels a reservation for its customers, the grid operator must inform Statnett of this so that the grid operator’s corresponding reserved capacity in the transmission grid can also be terminated by Statnett. This is necessary for efficient utilisation and distribution of available capacity.
