The Verbandsgemeinde of Konz and the affiliated local communities would like to promote the use of renewable energies. To this end, they want to continuously increase their share in the expansion of decentralized generation plants in the field of renewable energies and thus support the move away from nuclear power in a pioneering way.
For this purpose, the municipal council, after the approval of the local communities and the city of Konz, has transferred the performance of tasks in the field of renewable energies, especially in the field of energy production, to the municipal utilities of Konz. Accordingly, the operating statutes of the municipal utilities were expanded and an "energy" branch was formed.
Since then, the municipal utilities in Konz have been involved in the field of renewable energies in various subject areas for sustainable and resource-saving energy production and use.
The Verbandsgemeindewerke Konz are active in the energy sector in the following areas:
In 2012 and 2013, the Konz association of municipal utilities set up a total of 12 photovoltaic systems and operate these systems for the most part for their own supply and for the supply of third parties in the immediate vicinity.
The location, the size of the photovoltaic system and the use of electricity can be seen from the following table "PV systems":

Another field of activity of the Verbandsgemeindewerke Konz in the field of energy production is the operation of heating networks. With the competent operation of the two heating networks described below, the Verbandsgemeindewerke Konz also present themselves as a reliable supplier in the heat/heating sector.
Heat network school center:
From the autumn of 2015, the municipal utilities in Konz will supply the new Saar-Mosel-Bad and the adjacent school and sports center in Konz with thermal energy via a local heating network. The energy for feeding this local heating network is covered by various components as required. A woodchip heating system, a natural gas-powered combined heat and power plant and 2 gas boilers with different outputs and, in exceptional cases, an oil burner are available for energy production. With these components, the v.g. Local heating network can be operated economically all year round. At the same time, the different energy producers ensure comprehensive security of supply for the customers in the local heating network.
The annual energy requirement of the connected buildings is around 2,900,000 kWh. This corresponds to an amount of energy equivalent to approx. 290,000 liters of heating oil. The fuels are used individually depending on the price range and personnel costs. Energy generation and consumption are monitored and, if necessary, optimized via an energy management system.
The block-type thermal power station (CHP) there generates around 60% of the electricity requirement for the Saar-Mosel-Bad all year round, in addition to heating energy, so that the combined heat and power generation ensures a particularly effective use of the natural gas supply.
Local heating supply Karthaus:
The city of Konz has so far operated a local heating network in the area of the Karthaus monastery to supply the surrounding public buildings (primary school, day care center, canteen, monastery) and the local retirement home on Brunostrasse. This heating network was essentially fed with thermal energy via a wood chip boiler. To ensure the security of supply, especially in the event of system faults, the heating systems in the connected buildings remained in operation.
In the meantime, the German Red Cross has built a new old people's and nursing home on Albanstraße, in the vicinity of the existing old people's home. So that this building can also be supplied via the heating network, the system had to be expanded and optimized.
Since the Konz municipal utilities already operate a local heating network to supply the school and sports center and the Saar-Mosel baths, the municipal bodies have transferred the management of the Karthaus local heating supply to the Konz municipal utilities in order to achieve economic synergies.
As part of the optimization of the heating system by the municipal works in Konz, the central heating system, which previously consisted of a large woodchip boiler, was supplemented by 2 gas burners with modulating output and equipped with modern measuring and supply technology. In this way, year-round operation of the local heating network including redundancy can be ensured from an economic point of view. The partially outdated heating systems in the connected buildings could be switched off. This work was completed by the end of 2018/beginning of 2019.
The annual energy requirement of the connected buildings is around 2,100,000 kWh, which corresponds to a heating oil requirement of around 210,000 l.
An important aspect of generating electricity from renewable energies is the use of wind power.
The municipal utilities in Konz intend to expand the use of wind power on suitable areas within the municipal association area. The land use plan shows suitable areas for wind power in the area of the local community of Pellingen. The area there borders on an existing wind farm, which is located in the area of the adjacent municipality of Paschel and the district of Konz-Oberemmel.
In the meantime, the local community of Pellingen and the Verbandsgemeindewerke Konz have founded a joint institution under public law (AöR). This AöR with the name "Windpark Pellingen AöR" has the abbreviation "WIPP" and participates in WEAG Windkraft Konz GmbH & Co. KG for project planning of wind turbines in the Pellingen area.
In the first half of 2019, WEAG Windkraft Konz GmbH Co. KG submitted applications for approval for several wind turbines in the Pellingen district.
Three more wind turbines, which are about as high as Cologne Cathedral, started up in December 2021. The three new wind turbines produce up to 38 million kilowatt hours of electricity a year.
For comparison: According to the energy atlas, electricity consumption in the entire Konz municipality in 2018 was 110 million kilowatt hours. In purely mathematical terms, the new wind turbines in Pellingen can therefore produce almost a third of the entire electricity for the association of municipalities. In the Gusterath substation, the electricity is fed into the Westnetz grid.
Further information can be found on the website of "Windpark Pellingen" - a joint company of WEAG Power GmbH & Co. KG and Windpark Pellingen AÖR, an institution under public law of the Konz municipality and the local community of Pellingen:
"Windpark Pellingen AöR" (WIPP)
The abbreviation "WIPP" stands for " Pellingen AöR wind farm “.
This is a joint institution under public law (AöR) of the two sponsors:
- Verbandsgemeinde of Konz (Verbandsgemeindewerke – Energy sector)
- Municipality of Pellingen
The aim is to be involved right from the start in the project planning and implementation of wind turbines in the area of the high-altitude community of Pellingen. This should give the municipalities involved the opportunity to be involved in the value-added process.
The WIPP has a board of directors, which is provided by the management of the Verbandsgemeindewerke Konz. The business is also managed from there, since WIPP itself does not employ any staff.
How does participation take place? WIPP is a partner in the project planning company "WEAG Windkraft Konz GmbH & Co.KG". She has a 49% stake in this company, which initially has the task of planning wind turbines in the Pellingen district and submitting the application for approval. At the same time, it holds a 49% stake in Verwaltungs-GmbH.
The CEO of WIPP is also one of the two managing directors of the project planning company. After receiving the approval, the sponsors then decide whether to accompany the implementation.
