Fingrid’s 2025 annual review: about 10 data-centre connection agreements are not the August 5 GW total

Fingrid’s Annual Review and Financial Statements 2025, published with the 3 March 2026 bulletin, says the company signed approximately 40 new connection agreements during 2025. Around one third concerned energy storage, and approximately 10 agreements were signed with data centres and with electricity production, respectively. Ten signed Finnish agreements are not nearly 5 GW of planned mid-August capacity, and they are not a Swedish hall.

Fingrid’s Annual Review and Financial Statements 2025 is the dated transmission-system source used here for the agreement count. It was published with the 3 March 2026 financial-statements bulletin. The annual review says that during 2025 Fingrid signed approximately 40 new connection agreements. Around one third of the agreements concerned energy storage, and approximately 10 agreements were signed with data centres and electricity production, respectively. Approximately and around are the authority’s words. A signed-agreement count is not an energised megawatt. The HTML bulletin of the same day does not reprint that count.

Two enquiry totals in the same annual review must stay on their own lines. In 2025 Fingrid received grid-connection enquiries on electricity consumption for roughly 37 gigawatts, on production for roughly 45 gigawatts and on grid energy storages for around 26 gigawatts. The companion 3 March bulletin, and the same annual review, also say connection enquiries increasing electricity-consumption capacity amount in total to over 100 gigawatts, more than half of which is related to data-centre projects. Enquiries are not the 40 signatures. One hundred gigawatts is not ten agreements.

A later Fingrid paper uses a third metric. The 18 August 2026 notice already stored in this register says data-centre projects with signed connection agreements had a planned final combined capacity of nearly 5 gigawatts by mid-August, including distribution-network projects. That is a planned-capacity observation on signed papers. It is not a restatement of the 2025 count of approximately 10 data-centre agreements. Mixing March and August invents a single Finnish queue the sources did not publish.

The annual review also records process geography, not a Swedish cell. The 3 March bulletin restates that in early 2025 Fingrid announced restrictions on connecting new industrial-scale electricity consumption and grid energy storage in southern Finland. The annual review adds that in November 2025 Fingrid expanded the connection-agreement inquiry procedure for large industrial consumption and storage from southern Finland to the whole country. Those sentences sit beside the southern-Finland tightness note stored from 30 January 2025. They do not name Horndal, Falun or Hamre.

DataCenterSweden records the 2025 annual review as a signed-agreement count published on 3 March 2026. No Swedish project identifier is attached. Nearly 5 GW stays on the August row. Over 100 GW of enquiries stays an enquiry total. Until a later paper names the projects inside the ten agreements, the count remains unsigned to any hall in this register.

Why it matters

Ten signed Finnish data-centre agreements are easy to paste together with 5 GW and 100 GW into one brochure cell. The 2025 annual review is usable only if the count, the enquiry total and the August planned-capacity sentence stay on three lines.

What remains unknown

The annual review does not name the approximately 10 data-centre counterparties, does not publish their megawatts, and does not assign any agreement to a Swedish hall.
