Take a look at our company chronicle.

For over 20 years, HO-MA has stood for the highest quality and expertise in this field, continuously evolving. Explore this page to learn about our company history and significant milestones we have achieved throughout our journey.


Establishment of HO-MA Elektro Aggregate Service GmbH on 24.11.1992


Commencement of business operations on 02.01.1993 in Berlin, Siemensstadt. From the outset, the focus is on servicing, maintenance, and repair of backup generators within Berlin. This quickly expands to include the installation of complete emergency power systems. Gradually, the service area expands to encompass the state of Brandenburg.


Since September 01, 1996, HO-MA Elektro Aggregate Service GmbH has been providing training. The expansion of the service area and a continuously growing customer base necessitate the relocation to new, suitable premises by the end of the 1990s.


Relocation to the premises at Otternbuchtstraße 20a (13599 Berlin) in mid-2000, accompanied by an expansion of the service area.


The new branch in Sangerhausen (Saxony-Anhalt) is established in mid-2002, further expanding the operational area. Here too, a competent and always dedicated team works for the customers, following the motto:


On October 01, 2005, the scope is expanded to include the rental business. Nationwide and in neighboring countries, soundproofed rental generators ranging from 15 to 2,000 kVA are offered. Additionally, a wide range of accessories such as fuel tanks, cables, transformers, distribution panels, load resistors, and light towers are available.


The distribution of standard generators in hood and container construction complements the range of services. As a dealer, HO-MA becomes the right point of contact for numerous customers.


The sale of particulate filters and switchgear cabinets becomes part of the range of services.


In addition to its dealership activities, HO-MA becomes an authorized service center for SDMO generators.


The new corporate design is introduced. The completely redesigned website also goes live. In addition to its dealership activities, HO-MA now also becomes an authorized service center for MOSA generators.


Since mid-year, HO-MA has been distributing mobile gasoline and diesel generators, as well as water pumps, for use on construction sites, camping, or in the garden through the HO-MA online shop. Customers can find guidance on what to consider when making a purchase through a selection assistance page.

Anniversary: For 20 years, HO-MA Elektro Aggregate Service GmbH has been synonymous with expertise, reliability, and top-notch customer service in the field of emergency power technology. The scope of operations continues to expand, and the rental and sales departments operate nationwide.


Starting from April, HO-MA is also represented in Stade near Hamburg, thus expanding its presence in the northern region. The employees at this branch bring with them years of experience in the field of backup power systems and emergency power technology.


The service offerings of HO-MA Elektro Aggregate Service GmbH are TÜV-certified. The subsidiary company specialized in manufacturing, HO-MA Notstrom Sonder- und Anlagenbau GmbH, is established.


The web presence for service offerings and inquiry products is merged with the HO-MA online shop, allowing the complete range of services to be accessible through a single domain.


HO-MA moves into its new business premises at Motardstraße 101 (13629 Berlin). The newly constructed hall allows for further growth and the production of in-house products.


All employees enjoy the new working atmosphere in the new building. Modern workstations with height-adjustable desks and, upon request, 2 or even 3 monitors have become the new standard. Additionally, a 650 kVA training generator was acquired and installed in a concrete enclosure. This laid the foundation for our state-of-the-art training system.


The idea of an internal training academy is born and now being pursued. Through a major contract in Lithuania, we were able to gain valuable experience in international business, both in rental and service.
Standardaggregate werden nun mit unserem neuen Logo an unsere Kunden geschickt, um die Marke HO-MA Notstrom weiter im Markt zu etablieren.


Our Anniversary: 25 Years of HO-MA Emergency Power. We celebrated our 25th anniversary with our customers and strategic partners during an in-house exhibition.
Our training academy is now being established by our new training director. Regular internal training sessions for all employees will be conducted from now on. This allows us to elevate our know-how to a new level and stay one step ahead of our market competitors.


Our strategic realignment is beginning. The move from the small Stade to the larger Hamburg is the first step. As a second step, our new facility in Leipzig/Halle in Wiedemar starts operating.
We proudly present our first promotional video, which was created as part of a 4-month marketing project.


We used the pandemic period to fundamentally restructure our quality management and integrate it into all processes. A team supports our QMB in implementing this across all departments.
At last, we have our own backup generator and remain operational for our customers even during power outages.


Our new website goes live, showcasing a state-of-the-art online presence. We have decided to now present both companies on a single website.
