Hertener Energiehandelsgesellschaft

Hertener Energiehandelsgesellschaft mbH (HEH) is a German energy company belonging to the Hertener Stadtwerke group, the municipal utility (Stadtwerke) of the town of Herten in North Rhine-Westphalia. It functions as the group's energy trading and supply arm, active in the procurement and sale of electricity, natural gas, district heat and water for customers in Herten and the surrounding region. As part of a Stadtwerk, its business is closely tied to the local community and to the public infrastructure of the town. The parent group, Hertener Stadtwerke GmbH, traces its origins to the start of gas supply in Herten in 1900, and the group has described itself as being "125 years in service for Herten." Over the decades it has grown from a gas supplier into a diversified municipal utility whose core business is the supply of electricity, natural gas, heat and water, complemented by energy services and solutions that support efficient energy use. Beyond energy, the group also operates leisure and swimming facilities — the Copa Ca Backum water, sauna and wellness world, taken over from the city in 1986, and the Westerholt indoor pool, operated since 1990 — as well as activities in settlement development under the Hertener brand. Ownership of the group is entirely public. Hertener Stadtwerke GmbH has a single shareholder, Hertener Beteiligungsgesellschaft mbH, which is itself a wholly owned subsidiary of the City of Herten; in effect, the utility belongs to the citizens of the town. The company is overseen by a supervisory board composed of ten city council representatives, five employee representatives of the Stadtwerke and one representative of the city, while Thorsten Rattmann serves as managing director (Geschäftsführer). HEH's role within this structure is the commercial trading and supply of energy. Its offerings sit alongside the group's broader portfolio of energy products, services and solutions, including modern energy-supply concepts and, more recently, products supporting the energy transition such as photovoltaic packages for households. The company operates in the German energy market, with a clear regional focus on Herten and its region, and it communicates with customers and the public through the Hertener Stadtwerke website, newsletter and press channels.

The history of Hertener Energiehandelsgesellschaft mbH is bound up with that of the Hertener Stadtwerke group, the municipal utility of Herten in North Rhine-Westphalia. According to the group's own account, its story began with the start of gas supply in Herten in 1900, and it has since grown continuously. The group describes itself as having been "125 years in service for Herten," a milestone it marked with a jubilee film looking back at its development and forward to its future. Over the twentieth century the municipal utility expanded from gas into the broader set of services expected of a German Stadtwerk. Its core business today is the supply of electricity, natural gas, heat and water, supplemented by energy services and solutions that promote conscious and efficient use of energy. The group also diversified beyond energy: in 1986 it took over the former Backum open-air pool from the City of Herten and over the years transformed it into the Copa Ca Backum water, sauna and wellness world, and since 1990 it has operated the Westerholt indoor pool, used mainly by schools and clubs. Under the Hertener brand it is also active in settlement development. Hertener Energiehandelsgesellschaft mbH represents the energy trading and supply function within this group. It is registered as a German company and is associated with the Hertener Stadtwerke organization and its website. Its business covers the procurement and sale of energy — electricity, gas and heat — for customers in Herten and the region, alongside the group's wider portfolio of energy products and services. Ownership has remained public throughout. Hertener Stadtwerke GmbH has exactly one shareholder, Hertener Beteiligungsgesellschaft mbH, which is a 100% subsidiary of the City of Herten; in simple terms, the utility belongs to the citizens of the town. Governance rests with a supervisory board of ten city council representatives, five employee representatives of the Stadtwerke and one city representative, with Thorsten Rattmann as managing director. In recent years the group's communications have emphasized the energy transition and local service. Its website promotes products such as photovoltaic action packages that allow households to generate their own solar power, reduce grid purchases and become more independent of rising electricity prices, with 0% VAT where legal conditions are met. News and press releases document ongoing investment in infrastructure, notably the expansion of the district heating network in the Mühlenviertel in Herten-Langenbochum and related works in Herten-Disteln, as well as community and educational initiatives such as a climate and environmental protection homework booklet distributed to around 900 pupils. Through these activities, HEH and its parent group continue to position themselves as a customer-focused, future-oriented and responsible local energy provider for Herten and its region.
