Polarnode’s proposed Mustakorpi development in Kuopio has an approximately 32-hectare design reservation within a 92.7-hectare EIA area. The operator advertises 200 MW grid capacity and a 2028 power target; the October 2026 programme’s approximately 250 MW availability figure remains unreconciled. The programme assesses approximately 385 MW IT and 500 MW total electricity demand, not approved capacity. The programme reports zoning began in spring 2026, insufficient fibre for the development and district heating at least 1 km away. EIA consultation opened October 21, with comments scheduled to close November 19, 2026.

Site & development

Land and site control context

Reported rounded

The October 14, 2026 EIA programme identifies an approximately 32 ha design reservation within a broader 92.7 ha assessed project area. The reservation covers portions of 297-411-3-94, 297-411-3-89, 297-411-3-131 and 297-411-3-33. Programme reported approval was December 10, 2025, with an 18-month term from signing; no expiry is calculated without the signature date. Reservation is not ownership or verified current title.

Site location

Reported rounded

Mustakorpi development between Hiltulanlahti and Pellesmäki, Kuopio. The operator advertises approximately 32 ha; the October 2026 EIA programme places that design reservation within a broader 92.7 ha assessed project area. These are different boundaries of the same undertaking, not a surveyed ownership polygon.

Additional project facts

Eia programme capacity scenarios context

Reported rounded

Version B of the October 14, 2026 programme assesses VE1 at approximately 385 MW IT and 500 MW total electricity demand, with backup generator fuel input approximately 1,700 MW thermal. VE2 adds optional 200 MW electrical gas generation with indicative 465–515 MW thermal fuel input. These are maximum impact assessment alternatives, not approval, a selected configuration, commissioned capacity or current IT load. Electrical output, demand and thermal fuel input must not be added or converted.

Eia programme zoning history context

Reported rounded

Programme section 3.3.4/p 12 reports that zoning for the Mustakorpi business area began in spring 2026 and proceeds separately alongside EIA. Spring is the reported precision; no day or quarter is established. The earlier operator forecast remains a separate historical statement.

Technical details (3)
Utility service

Reported context

Polarnode advertises 200 MW maximum grid capacity and a 2028 power target. The October 14, 2026 EIA programme separately describes about 250 MW available electricity and assesses a scenario with approximately 500 MW total electrical demand. Their relationship is unresolved; these statements do not establish contracted allocation or operating IT, and no source establishes that 200 MW supersedes 250 MW.

Fiber

Reported context

The operator advertises connectivity to the site. Programme section 3.1 reports insufficient fibre for the proposed development, without establishing that no routes exist.

Water supply

Reported context

Operator advertises water/sewer and heat-use access; no verified allocation, cooling design or consumption. The programme places district heating at least 1 km away. Advertised heat-use access is not a verified completed connection or offtake agreement.
