Stadt Frankfurt am Main - Amt für Bau und Immobilien is seeking an electrical contractor to equip a new municipal storage site with solar generation, battery storage and e‑charging, showing how energy storage is now built into standard building projects rather than treated as an add‑on.
On 2nd April 2026, Stadt Frankfurt am Main - Amt für Bau und Immobilien published a contract notice for an electrical installation for a new storage site. The project bundles together the full electrical fit‑out for the facility, including a photovoltaic (PV) system, a battery storage system, e‑charging stations and other electrical components.
Although the notice does not detail capacities or layouts, the scope is clear: the buyer wants a single contractor to deliver a complete power and charging package. That means responsibility for coordinating the PV array, the battery storage unit and the electric vehicle charging points with the wider electrical installation.
For suppliers, this structure underlines a trend seen in many recent building projects. Electrical works are no longer just about lighting, sockets and basic distribution. They now often include on‑site generation, storage and e‑mobility infrastructure as core elements of the brief.
The Frankfurt storage site is one of a growing number of public projects where battery storage is specified alongside PV from the outset. Across recent tenders, storage appears less as a pilot and more as a standard design feature.
In December 2025, the Magistrat der Stadt Gedern launched a PV system installation for a new fire station. That project combines PV modules, cabling, a hybrid inverter, a smart meter and battery storage on the station roof. Pairing storage with emergency services infrastructure suggests a focus on power availability and better use of on‑site generation.
Similarly, in November 2025 the Zweckverband Staatliche weiterführende Schulen im Süden des Landkreises München tendered a photovoltaic system for a school campus in Deisenhofen, specifying glass‑glass modules, inverters, switchgear, energy storage and extensive cabling. Storage here is part of the basic equipment for an education campus, not an experiment.
By February 2026, the Stadt Waldenbuch was seeking electrical engineering services that included a PV system, main distribution cabinets, circuit sub‑distributors, extensive cabling, lighting, a central battery, clock systems, public address, fire alarm and data technology. Again, a central battery is treated as one of several standard systems in the building.
The pattern continues in specialised facilities. In February 2026 the Staatsbetrieb Sächsisches Immobilien- und Baumanagement tendered electrical installations for an archive, combining a central battery system with a PV installation, distribution systems, lighting, alarm systems and network infrastructure. The Landratsamt Oberallgäu’s electrical installation services notice from February 2026 similarly calls for a central battery system alongside sub‑distributions, low‑voltage and low‑current lines, lighting and data cabinets.
At the larger infrastructure end, Versorgungsbetriebe Bordesholm GmbH’s battery storage system construction tender from January 2026 focuses on a dedicated storage facility near the PV open space park Eiderstede, covering civil works, site enclosure and cable connections, with an option for maintenance. That project shows storage being deployed at a site‑level scale around a solar park, rather than only within individual buildings.
Taken together, these procurements point to battery storage becoming a regular part of public building and energy infrastructure programmes. The Frankfurt storage site project sits squarely within this shift, even though it is framed simply as part of an electrical installation package.
A notable feature of the Frankfurt tender is the inclusion of e‑charging stations as part of the depot’s electrical design. While the notice does not specify user groups, integrating charging into a storage and operations site aligns with a wider move to prepare municipal fleets and staff parking for electric vehicles.
Other authorities are pairing charging infrastructure with substantial upgrades to power supply and controls. In October 2025, Land Schleswig-Holstein, represented by Gebäudemanagement Schleswig-Holstein AöR, issued a charging infrastructure planning notice for the government campus Düsternbrook. That project involves upgrading the power supply, expanding electric vehicle charging and integrating photovoltaic systems while renewing ageing electrical systems.
In November 2025, transport operator RVK | Regionalverkehr Köln GmbH tendered for GMH charging infrastructure at a new operating yard for fuel cell and battery‑electric buses. The specification spans medium‑voltage fields, transformers, low‑voltage distributions, DC chargers and a load management system. Here, charging is tightly linked with grid‑side equipment and active control of demand.
Emergency and control facilities show a similar pattern. In February 2026, Stadt Borken went to market for fire and rescue station electrical work, including charging infrastructure, a photovoltaic installation, low‑voltage switchgear and a suite of safety and communication systems. The Landratsamt Eichstätt’s February 2026 electrical installation services notice for a new integrated control centre similarly combines low‑voltage distribution, e‑mobility charging stations, lighting systems, backup generators, UPS systems and fire protection.
Compared with these complex, availability‑critical sites, the Frankfurt storage project appears more straightforward. Yet the inclusion of e‑charging alongside PV and battery storage shows the same principle: charging points are increasingly designed as part of a managed electrical ecosystem, not bolt‑ons to a basic grid connection.
Another clear theme across recent notices is the move to procure broad, all‑inclusive electrical packages rather than separate trades for power, data, safety and automation. The Frankfurt tender, with its reference to a PV system, battery storage, e‑charging and “various electrical components”, fits this model.
In February 2026, Stadt Lübbenau/Spreewald sought a contractor for electrical installation at the new Kita Spiel und Spaß. The scope spans a PV system, main and sub‑distributions, extensive cabling, lighting and emergency lighting, lightning protection, VoIP, media technology, a fire alarm system and a data network.
In March 2026, Amt Schenkenländchen’s electrical installations notice combined high‑voltage systems, sub‑distributions, cabling, lighting, a central battery system, a venetian blind system with central control and lightning protection. The Zweckverband Schulzentrum’s March 2026 electrical installation works tender likewise brings together a PV system, low‑voltage distribution, lighting fixtures, safety lights, lightning protection, a data transmission network and building automation wiring.
More specialised settings follow the same pattern. The Staatliches Bauamt Freising’s March 2026 electrical engineering services for a sports facility for the Federal Police cover emergency lighting, low‑voltage systems, lighting, security installations and data transmission networks. Vermögen und Bau Baden-Württemberg, Amt Tübingen’s March 2026 electrical installation for a university innovation campus includes power distribution boards, lighting systems, control panels, laboratory distribution boards, data and fire alarm cabling and specialised systems.
For contractors, the message is that public clients expect integrated capabilities. Delivering PV, storage and EV charging now sits alongside responsibility for safety systems, ICT networks and building automation. The Frankfurt storage depot tender is a smaller example of this, but it shares the same integrated outlook.
The Frankfurt electrical installation project shows how battery storage is becoming a routine part of municipal capital works. Similar notices for schools, archives, depots, fire and rescue stations and transport yards all point in the same direction: public buyers are commissioning combined packages of generation, storage, charging, safety and communication systems.
As this contract progresses, key points of interest for the market will be how the balance between PV, storage and e‑charging is specified and how responsibilities for control and monitoring are allocated within the electrical scope. The growing number of tenders that treat storage and smart electrical systems as standard suggests that more such opportunities are likely to appear across future building and refurbishment programmes.
