Frankfurt's ageing substation forces Mainova to rethink €40M rebuild plans
Frankfurt's Mainova is reassessing plans to modernise the ageing substation at Heide- and Schopenhauerstraße. The facility, which has powered Nordend and Bornheim for over 50 years, can no longer be fixed with simple repairs. A full overhaul is now required, but the timeline and approach are changing.
Earlier this year, residents noticed survey teams conducting subsurface tests and drilling boreholes at the site. These investigations aimed to produce a geotechnical report for the planned rebuild. The original project, set for completion between 2028 and 2029, involved demolishing the current structure and constructing a new one at a cost of €35 to €40 million. The design also included a land swap with the neighbouring playground, which was to be relocated and expanded on the substation's larger plot.
However, shifting conditions have forced Mainova and its subsidiary, Netzdienste Rhein-Main (NRM), to revise the entire plan. Further surveys may still be needed to assess the site's exact state before final decisions are made. The fate of the playground remains uncertain, as its redesign and timing now depend on the updated proposals.
No public details have emerged about how the substation's modernisation might affect playground access or whether alternative solutions have been explored by Mainova or the city.
The substation's future—and that of the adjacent playground—rests on the revised plans. Additional assessments will determine the next steps for both the facility and the surrounding area. A final decision on costs, timing, and design has yet to be announced.
