Eurelectric’s 3 June 2026 Exergi note is a platform snapshot, not a named hall megawatt

On 3 June 2026 Eurelectric published a Stockholm Exergi Open District Heating case, sourced to Exergi. It records more than 30 data centres across 16 providers and a SEK 2 million per megawatt per year revenue signal. A platform count is not a metered 2026 megawatt-hour and not Horndal.
Eurelectric’s 3 June 2026 story is the dated heat-platform source used here. It says Stockholm Exergi’s Open District Heating platform allows data centres to sell waste heat into the city’s district-heating network under standardised, temperature-indexed contracts. The source line is Stockholm Exergi. A temperature-indexed contract is not a named hall delivery.
The commercial sentences must stay Exergi’s. The utility invests in pipe connections while data-centre operators invest in heat pumps, converting a cooling cost into a revenue stream of SEK 2 million per megawatt per year. A neighbouring metric on the same page writes about €170,000 per megawatt per year paid to operators. Those are platform price signals. This article does not convert one into the other and does not attach either figure to a named Swedish hall.
The cluster sentences stay a count, not a campus. The platform now connects more than 30 data centres across 16 providers. Key metrics on the same page name more than 30,000 apartments heated annually, 3.5 percent of Stockholm’s heat supply and a target of 10 percent. Thirty-plus and 3.5 percent are snapshot sentences. They are not a 2026 metered offtake for one operator.
Named Stockholm heat rows stay on their own papers. Conapto’s Exergi arrangement, GlobalConnect’s southern Stockholm heat sentence, the DigiPlex retrofit and Google Horndal’s readiness wording are different issuers and dates. A platform snapshot does not become those files.
DataCenterSweden records 3 June 2026 as an Open District Heating platform snapshot. No project identifier is attached. The next update would need a later primary source that names a new hall contract or a measured megawatt-hour. Until then, 30-plus halls and SEK 2 million per megawatt per year stay platform sentences — not reserved heat for a named campus.
Why it matters
A 30-plus-hall heat headline with a kronor-per-megawatt signal is easy to file as live Stockholm offtake. The June snapshot is usable only if the count stays a platform, not a named hall row.
What remains unknown
The page does not name the 30-plus halls, does not publish a 2026 megawatt-hour and does not attach SEK 2 million per megawatt to a single campus.
