Enquiries concerning grid capacity
First, Statnett will provide a confirmation that we have received your enquiry
Early stage – guidance: Some customers submit enquiries early in their own project run, and only need provisional guidance. Statnett will be able to advise them within a few weeks, based on available information and without undertaking any analyses, free of charge.
Early stage – grid analysis: In some cases, the customer’s MW requirements and location are not yet confirmed, and they wish to have multiple possibilities assessed. If customers require more information than what we can provide without performing analyses, the grid operators may then choose to charge for making a grid analysis.
Clarify whether the customer’s project can be connected to the grid without grid investments
Once the customer’s power requirements and location have been reasonably ascertained, Statnett must perform an analysis of whether the customer’s order is operationally sound, free of charge. Examples of time spent on the analysis:
Simple cases take around 2–3 months.
More complex cases can take up to 6 months. This time is necessary to more thoroughly assessment. Customers will be kept informed of progress.
Allocate grid capacity
If we concludethat there is sufficient capacity in the grid, the customer can reserve grid capacity. The grid owners must collaborate on the allocation of capacity. A deadline should be set for using the reserved capacity. If the capacity is not used by the deadline, it is made available to other customers. For production projects, we set a deadline for construction to start within two years. Allocation of grid capacity is described on the NVE website.
Assessment of grid measures
If it becomes apparent that there is a need to assess grid measures to meet the customer’s need, Statnett is obliged to perform these assessment, often in collaboration with local grid owners. This type of analysis is discussed in more detail here. The customers must cover their proportional share of costs incurred after 1.1.2019. Statnett will enter into agreements with the customers before the investigations start. The assessment is carried out in dialogue with customers and other affected grid owners. Examples of time spent on the analysis, after the work on entering into the agreement is finished.
- Simple – 2–4 months: for example, increased transformer capacity in an existing substation
- More extensive – 6–12 months: for example, a new substation or minor works on lines
- Major – requires application processing by the authorities: 6–12 months in Statnett + 12–18 months for external quality assurance and application processes
Planning and implementing measures in the grid
It takes time to plan and implement projects at the transmission grid level, including necessary application processes (licence). Here are some examples of how much time different measures can take, including application processes:
- Operational measures: 0–12 months
- Increased transformer capacity: 5–4 years
- New substation: 4–7 years
- New power line: 5–10 years
