Polarnode’s Sarvenmaa proposal in Keminmaa remains in environmental assessment. The operator markets more than 500 MW of grid capacity, while assessment considers roughly 1,000 MW peak demand; neither is operating IT load. A proposed 400 kV connection would serve the approximately 109–110-hectare site. The August 2026 planning document names Tornator as owner and targets zoning stages in 2027, without establishing a completed sale or approval. FCG supports planning and environmental assessment. The authority requests further generator, emissions, noise and cooling information and recommends considering a smaller alternative.

Reviewed sar municipal parcel context

Reported rounded

The August 3, 2026 municipal participation and assessment plan identifies an approximately 110-hectare forestry planning area concerning parcel 241-407-3-30 and names Tornator Oyj as owner. This is a dated planning ownership statement, not a current land register extract or proof that a proposed sale closed.

Source

Reviewed sar zoning schedule context

Reported rounded

The August 3, 2026 plan states that no master or detailed plan was then in force at the site and that a detailed plan is needed to enable the data centre. Its preliminary schedule places the proposal stage in spring 2027 and approval stage in autumn 2027. These are planning targets, not granted approval, current entitlement or a building permit.

Source

Reviewed sar team context

Reported rounded

The municipal participation and assessment plan names FCG Rakennettu Ympäristö Oy as planning consultant; the October 14, 2026 authority opinion also identifies FCG as EIA consultant. These are scoped professional roles, not EPC or construction contractor appointments.

Source

Reviewed sar technical holds context

Reported rounded

The October 14, 2026 authority opinion calls for maximum generator counts, electrical and fuel input ratings, emissions and noise information, and cooling equipment details in the assessment report. It recommends examining a smaller alternative alongside the up to-11-building proposal. These are assessment requirements and a recommendation, not project rejection or an approved generator design.
