Meta Odense data center, Odense SØ, Denmark

Meta's Odense data center, in Odense in the Region of Southern Denmark, is a three-building campus that came online in 2019 and is best known for heating thousands of local homes with its servers' waste heat. Meta says its investment in the Odense data center exceeds 10 billion Danish kroner and that the site supports 175 operational jobs.

The first 55,000-square-meter building opened in 2019, and Meta announced a 30,000-square-meter expansion in 2020. In December 2021 it said it would add two more buildings of about 90,000 square meters, taking the campus to nearly 200,000 square meters and its total investment to more than 13 billion kroner. A year later Meta stopped that plan. Its contractor Aarsleff said in December 2022 that its 2.4 billion kroner contract had been terminated and work "will be stopped immediately," after earthworks, concrete work and cable trenches were already done. "We have decided not to move forward with the planned expansion beyond three buildings and we will be ending construction work on the two additional buildings," Meta's Nordics communications manager Peter Munster told DCD, adding that AI workloads require "a different type of data center."

The campus is connected to the Odense district heating network. Meta says 165,000 megawatt hours of surplus heat from its server halls go to the system run by Fjernvarme Fyn and reach up to about 9,000 households in Odense. It says three new solar projects in Denmark, totaling about 210 megawatts, are part of the renewable energy it buys to match its data centers' electricity use.

Meta also owns 212 hectares of land at Andrup in Esbjerg, bought in 2021 for 277 million kroner as a possible site for a future data center.
