Goodman will supply up to 50 MW of recovered waste heat from its planned FRA02 data center in Neu-Isenburg, Germany, to Stadtwerke Neu-Isenburg's (SWNI) district heating network. The 54 MW IT-capacity facility is scheduled to enter service in 2028 and will heat roughly 600 buildings across three local districts.

The agreement, signed with the City of Neu-Isenburg and SWNI after four years of joint planning, routes heat into the Gewerbegebiet Süd industrial estate, the Neue Welt residential area, and the Waldschwimmbad public pool. SWNI will build and operate the distribution network, while Goodman will fund the on-site equipment that recovers and hands off the heat.

What does the deal cover?

• Up to 50 MW of waste heat recovered from FRA02
• Supply to 600 buildings across three districts
• 54 MW IT capacity at the data center
• High-voltage substation scheduled to finish this year
• District heating plant slated to break ground in 2028

Where is FRA02 and what is its current status?

The site sits at Rathenaustraße 29-31 in Neu-Isenburg, just south of Frankfurt. Structural topping out took place earlier this year, and Goodman confirms a dedicated high-voltage substation will be completed in 2025. The heating plant itself is scheduled to begin construction in 2028, the same year FRA02 enters commercial service. Goodman has already procured the land for the plant and will finance the heat-recovery kit on the data center side.

What did the partners say?

Christof Prange, country manager for Germany at Goodman, said: "Recovering waste heat from FRA02 for use by local homes, businesses, and community facilities will deliver a meaningful long-term benefit for Neu-Isenburg. Together, we have worked through the technical, planning, and commercial requirements needed to turn our shared ambition into tangible infrastructure."

Mayor Dirk Gene Hagelstein linked the project directly to the city's climate plan. "Decarbonizing our heat supply is a key priority for Neu-Isenburg, and FRA02 is helping turn that ambition into reality," he said, citing a closed-loop cooling system, rooftop PV arrays, and a green facade as the sustainability measures embedded in the development.

Kirk Reineke, managing director of Stadtwerke Neu-Isenburg, added: "FRA02 will provide a valuable source of recovered heat for our district heating network and support our decarbonization goals. Projects like this depend on strong, long-term partnerships."

How will the heat exchange work in practice?

The data center will reject heat through a closed-loop cooling system designed to limit drinking-water consumption, an issue that has shaped permitting debates across the data-center-dense Frankfurt region. Goodman will fund the on-site heat-recovery and handover skids; SWNI takes ownership at the boundary and runs the network outward. A 50 MW thermal offtake at 54 MW IT load is a high utilization ratio, and the project will rank among the larger day-one heat-recovery schemes in European data center development.

What is the wider context?

Goodman, headquartered in Australia, is developing data center projects across Hong Kong, Australia, the United States, Japan, and Germany. FRA02 serves as the company's flagship German site and one of a small cohort of European facilities being built with a municipal heat offtake written into the original design, rather than added later as a retrofit. For Neu-Isenburg, the same parcel of land now anchors both a digital infrastructure investment and a heat decarbonization programme.
