  Fingrid technical requirements for large demand facilities connected to the transmission grid, applied immediately from 12 June 2026

  On 12 June 2026 Fingrid, the state-owned transmission system operator, published 'Technical requirements for large demand facilities' and applies them immediately to new and modified demand facilities (such as data centres) connected directly to the transmission grid. The content matches the Type D demand facility requirements in the KJV2026 draft grid code (PP-FI-004). Distribution-connected facilities follow once KJV2026 is confirmed by the Energy Authority. Until then the KJV2018 demand grid code stays in force alongside Fingrid's general connection terms.

  Electricity used in data centres moved from the lower electricity tax class II to the general class I from 1 July 2026

  Act repealing provisions of the Act on Excise Duty on Electricity and Certain Fuels (government bill HE 156/2025, linked to the 2026 budget; Finance Committee report VaVM 28/2025 of 5 Dec 2025 recommended adoption unchanged). From 1 July 2026 electricity consumed in data centres no longer qualifies for tax class II (0.05 c/kWh) and is taxed at the general class I rate of 2.24 c/kWh, an increase of 2.19 c/kWh. The government estimated extra revenue of EUR 47 million a year at 2026 levels. A replacement subsidy scheme for data centres was announced at the same time (see profile) but the government dropped it in the 2027 budget talks (Sept 2026).

  2.24 EUR cent/kWh General class I rate now paid by data centres; class II rate was 0.05 c/kWh (increase 2.19 c/kWh). Date = government decision to submit the bill (23 Oct 2025); enactment date not read.

  Act 846/2024 amending the Energy Efficiency Act: data centres of 500 kW IT power or more brought under EU EED data centre rules

  Act 846/2024 (issued 19 Dec 2024, in force 30 Dec 2024; government bill HE 170/2024) adds data centres to the scope of the Energy Efficiency Act and a new chapter 5 b implementing Article 12 of Directive (EU) 2023/1791. Operators of data centres in Finland with installed IT power demand of at least 500 kW must publish the region (maakunta) where the data centre is located (first by 31 Dec 2024, changes by 15 May of the following year) and fall under the EU data centre energy performance reporting scheme. The Energy Authority (Energiavirasto) supervises compliance, with rights to obtain information and inspect premises. Defence, civil-protection and vital-function data centres are exempt.

  Draft Electricity Market Act amendment: priority procedure for grid connection offers when capacity is short, data centres kept out of the top group

  The Ministry of Economic Affairs and Employment (TEM) has circulated a draft bill amending the Electricity Market Act to rank grid connection requests when network capacity is insufficient. Group 1 (protected) covers households, most small and medium industry and critical uses, including non-data-centre consumption sites up to 3 MW connection power; data centres are excluded from group 1 and have different limits from other consumption. Groups 2 to 4 would be processed twice a year. A customer that commits flexible generation of at least 80% of the site's peak power on an organised market moves from group 3 to group 2; a commitment to supply from a named power plant is also possible. Fingrid supports the bill and wants it in force as fast as possible. Comments closed around 8-9 Oct 2026; the bill is expected in Parliament later in autumn 2026.

  KJV2026 draft grid code for demand connections: facilities above 30 MW must ride through faults and be able to limit power intake

  Fingrid put the KJV2026 grid code specifications for demand connections out for comment from 12 June to 21 August 2026. They cover demand facilities and distribution networks connected to the Finnish power system, with significant requirements for facilities whose rated demand capacity is above 30 MW, naming data centres, electric boilers and electrolysers. Such facilities must withstand grid disturbances (fault ride-through) and be able to limit their power intake from the grid. Planned entry into force is March 2027, after amendments and confirmation by the Energy Authority.

  Planned data centre register and registration obligation (government decision of 5 Dec 2025)

  The Ministerial Committee on Economic Policy decided on 5 December 2025 to launch a cross-administrative legislative project to create a register of data centres and set related obligations, to give authorities a fuller picture of data centre investments and operations, including security impacts. Security authorities will also examine data centre security. The same decision set out a 10-year electricity-based tax relief for registered data centres that reuse waste heat or exceed the required energy efficiency level (capped at EUR 30 million, from 1 July 2026); that aid was dropped in the 2027 budget talks (1 Sept 2026, reported by Xinhua/Yle). No thresholds or dates for the register are stated yet.
