Fingrid’s KJV2026 draft is a demand-code consultation, not a signed 5 GW queue

On 12 June 2026 Fingrid opened a public consultation, to 21 August 2026, on KJV2026 grid-code specifications for demand connections. Facilities above 30 MW, including data centres, would need fault ride-through and the ability to limit intake. A draft code is not a signed connection agreement.

Fingrid’s English consultation page dated 12 June 2026 is the dated code source used here. It says Fingrid is holding a public consultation from 12 June to 21 August 2026 on new Grid Code Specifications for Demand Connections, KJV2026. Comments may be sent in free form or as an annotated copy to gridcompliance@fingrid.fi. A consultation is not an in-force code.

The 30 MW sentence must stay a 30 MW sentence. KJV2026 applies to demand facilities and distribution networks connected to the Finnish power system. It sets significant system-technical requirements for demand facilities with a rated demand capacity exceeding 30 MW, including data centres, electric boilers and electrolysers. Those large industrial demand facilities would have to withstand disturbances — a fault ride-through requirement — and have the capability to limit their power intake from the power system. A requirement draft is not a reserved megawatt.

The two documents must stay two documents. After the summer 2026 consultation Fingrid will amend the requirements and submit them to the Energy Authority for confirmation, with a target of March 2027 for KJV2026 to enter into force. On the same day Fingrid also published a separate paper, Technical requirements for large demand facilities. Those requirements apply immediately to demand facilities directly connected to Fingrid’s transmission grid, because new large demand needs rules that complement KJV2018. They do not apply to demand facilities connected to distribution networks until the Energy Authority confirms the final KJV2026 text.

Named neighbouring papers stay on their own files. Fingrid’s August 2026 signed data-centre agreement note, the H1 2026 signed-agreement note, the 2025 data-centre connection-agreement paper and the southern-Finland consumption-tight note are different instruments. A demand-code draft does not become those signed-queue files.

DataCenterSweden records 12 June 2026 as a Fingrid consultation opening on KJV2026. No project identifier is attached. The next update would need a later primary source that names the confirmed code, a changed threshold or a named facility already held to the immediate transmission-grid paper. Until then, KJV2026 stays a draft — not a signed Finnish hall queue.

Why it matters

A Finnish code page that names data centres above 30 MW is easy to file as a new queue cap. The June draft is usable only if consultation and the March 2027 target stay open, and the immediate paper stays limited to direct Fingrid connectees.

What remains unknown

The fetched page does not print the confirmed KJV2026 text, a named Finnish campus already held to the immediate paper or a megawatt reserved under the draft.
