Rejlers Kapacitetskartor för Elnätsföretag (2026)

A short advisory article from the engineering consultancy Rejlers (7 Oct 2026) on how a distribution grid company can meet the capacity-information duty in 27 a § förordning (2022:585) without building a new system. It is vendor material: the article promotes Rejlers’ own GIS-based service and a webinar, so its “no new system needed” conclusion is a consultant’s view, not a regulator’s. Its description of the legal duty matches the ordinance text (Source - Förordning (2022-585) om elnätsverksamhet); the practical advice is the part specific to this source.

Key points

• The rule, as the article summarises it. Since 1 July 2026 distribution companies must publish information on available capacity for new connections: on their website, updated at least quarterly, “transparent, clear and geographically detailed”, and including capacity already subject to connection requests, the possibility of a connection with conditions limiting feed-in or withdrawal, and the basis for calculating available capacity. 27 b § adds that the company must first investigate what measures are needed to protect information it may not disclose.
• An information product, not a new technical system. The article argues the map can be built on data the company already holds in its network information system (NIS), connection cases and network-planning material, and that the grid model and the capacity map serve different purposes: the model describes the grid’s technical structure for internal use, the map helps an outside party see where conditions for a new connection are better or worse. The information can therefore be processed, classified and adapted before publication, and the company decides what becomes public and at what geographic detail.
• Guidance, not a connection decision. The map should answer “where might I have grounds to proceed?”, not “is a guaranteed amount of power available for my connection?” It cannot replace the technical assessment of a specific connection, and the article says that use of geographic analysis or interpolation should be stated clearly.
• Quarterly, not real time. The ordinance sets no requirement for a live link to internal systems. The article therefore proposes a controlled publishing process, with a separate public information model instead of publishing internal NIS data directly, and says the company’s work is limited to providing data extracts, taking part in decisions on method and publication level, and approving the result before each publication; later quarterly updates reuse the same structure.
• Value beyond compliance (the author’s claim). Project developers, producers, large consumers and municipalities get earlier and more realistic information; for the company it can reduce manual enquiries and “air bookings” (applications for capacity that is not actually needed) and help communication about connection times and forecasts.

Limits of this source

The article gives no examples of published maps, no cost or effort figures, and no information on how many grid companies have already complied. It was written by a supplier of the service it describes.
