(Sharecast News) - Investment firm 3i Infrastructure has agreed to invest approximately €300m to acquire a majority stake in Lefdal Mine Datacenter, a Norwegian data‑centre campus on the country's west coast.
3i Infrastructure said on Wednesday that Lefdal Mine Datacenter was being acquired from a fund managed by Columbia Threadneedle Investments, whose largest investor will reinvest alongside 3i Infrastructure. Completion was expected to take place in summer 2026.
The FTSE 250-listed firm added that the deal also includes a small portfolio of operating renewable assets. Including co‑investment, the overall commitment will total roughly €400m, with 3i Investments overseeing the transaction.
LMD currently has 37MW of operational capacity across its customer base, with a further 43MW under construction. 3i Infrastructure said the site benefits from Norway's "low‑cost, reliable power supply" and uses an underground location and closed‑loop seawater cooling system to deliver "high efficiency". Only one of six mine levels was currently in use.
Bernardo Sottomayor, head of European infrastructure at 3i Investments, said: "We are delighted to be redeploying some of the proceeds from the TCR exit into a high-quality asset like LMD. This transaction offers an attractive risk/return profile, whilst further diversifying our portfolio into a new subsector. The contracted existing capacity provides strong downside protection, and we see attractive growth opportunities to create value. We look forward to working with the management team to deliver a strong outcome for 3iN."
As of 0845 GMT, 3i Infrastructure shares were down 0.43% at 345.50p.
