Summary
- CVC DIF will acquire a significant majority stake in firstcolo from Cube Infrastructure Managers.
- firstcolo operates two near-full Frankfurt facilities and is developing the 24MW FRA7 campus in Rosbach.
- FRA7 combines secured power, high density cooling provision, and planned heat reuse as investors favour projects with a clearer route to delivery.
CVC DIF has agreed to acquire a significant majority stake in German colocation operator firstcolo, backing a platform that combines two near-full operating facilities with a 24MW expansion already under construction near Frankfurt.
The investment will be made through DIF Value Add IV, with Cube Infrastructure Managers selling its controlling position. Completion is expected by the end of September, subject to the remaining transaction conditions.
firstcolo serves more than 350 customers through two established Frankfurt region data centres. Its next phase of growth centres on FRA7 in Rosbach, where a 24MW gross capacity facility is being developed with power, permits, a fixed price construction arrangement, and initial customer commitments already in place.
FRA7 gives the transaction somewhere to grow
Construction at FRA7 began earlier this summer, moving the Rosbach project beyond the land and planning stage before CVC DIF entered the ownership structure. firstcolo puts the facility at up to 24MW gross capacity and around 16MW of IT capacity, with opening targeted for 2027.
The site is being designed around higher density computing rather than conventional colocation alone. firstcolo lists cooling configurations ranging from hot aisle containment to water based and in row liquid cooling, while the facility is intended to accommodate much denser racks than traditional enterprise halls.
That capability changes the mechanical and electrical package around the customer space. Concentrated GPU loads require larger power feeds, more capable distribution, higher flow rates through cooling loops, greater attention to water temperatures, and controls that can manage significant thermal changes without compromising redundancy.
firstcolo also targets a PUE below 1.2 for FRA7 and says the facility will use renewable electricity. Those design objectives will ultimately be judged against operating conditions, occupancy, customer density, and the way cooling plant performs through different seasons rather than against a single design figure.
CVC says the land, power supply, permits, and construction arrangements are already secured. In Frankfurt, where grid access can determine whether a site progresses at all, that package gives the development more substance than a speculative capacity pipeline.
Power and waste heat move into the investment case
A regional utility is expected to secure the facility’s energy supply, while firstcolo has also committed to making waste heat available to the local district heating network. The operator previously said the heat would be offered to Rosbach and the surrounding area without charge for 20 years.
Connecting a data centre to district heating is more complex than making heat theoretically available at the facility boundary. Network temperatures, seasonal demand, heat pump requirements, pipe routes, commercial agreements, and the cost of connecting buildings all determine whether rejected server heat reaches useful consumers.
Those practical questions are gaining weight in Germany and across Europe as planning policy and energy regulation place more emphasis on heat reuse. New data centres can reject large quantities of low temperature heat continuously, but the receiving infrastructure often has to be planned on a different timetable from the data centre itself.
FRA7’s cooling architecture gives the project another lever. Higher liquid temperatures associated with direct liquid cooling can improve the quality of recovered heat, reducing the temperature lift required before it enters some district heating systems. The actual arrangement at Rosbach will depend on customer deployments and the final heat network design.
Power access carries similar commercial value. As grid queues lengthen, investors are increasingly distinguishing between theoretical development capacity and projects where electricity supply has advanced far enough to support a credible opening date.
Operating assets anchor the development risk
CVC DIF is acquiring more than a future project. firstcolo’s two existing facilities already generate revenue from a broad customer base, giving the investment platform an operating foundation while FRA7 adds capacity.
That combination has attracted infrastructure capital across the European data centre market. Mature facilities provide contracted cash flow, while expansion sites create room for further growth without requiring an investor to assume all the risk of entering a new market from scratch.
Germany remains a particularly competitive environment. Frankfurt continues to absorb large cloud and colocation demand, but power constraints, construction costs, equipment lead times, and planning requirements are pushing developers towards secondary locations around the metropolitan region where land and electrical infrastructure can still be assembled.
Rosbach fits that pattern. It retains access to the Frankfurt market while giving firstcolo room to build a larger and denser facility than its existing footprint.
CVC says further high performance data centres could follow in Frankfurt and elsewhere in Germany. Each additional site will have to clear the same tests now embedded in FRA7: available power, a workable construction programme, customers prepared to contract capacity, and mechanical systems able to carry the densities expected from the next generation of compute.
