19.06.2023 - Energy System Transformation - ONERGYS in conversation with Stefan Rouenhoff MdB

Stefan Rouenhoff at Stephan Waerdt's during their conversation in Berlin Stefan Rouenhoff and Stephan Waerdt during their conversation in Berlin.

In his function as a member of the board of the Bundesverband Kraft-WärmeKopplung e.V. (Federal Association of Combined Heat and Power) Stephan Waerdt (ONERGYS) visited member of the German Bundestag, Stefan Rouenhoff in Berlin.

During the meeting, they exchanged views on current matters related to the energy transition. Both agreed that to be efficient the transformation of the heat and power supply must be open to new technologies and include bioenergy, especially in rural areas.

In this context, combined heat and power (CHP) plays a decisive role both in heating grids and in the power plant parks to cover the residual load in so-called "dark slack periods". CHP must therefore also be explicitly included in the new Building Energy Act (GEG). Rouenhoff and Waerdt also want to continue the dialogue at local level in the district of Kleve with a view to municipal heat planning.

16.06.2022 - DENSO spark plugs product improvement

As a renowned manufacturer - with the highest quality and technology standards - DENSO® has made an improvement to the electrode material.

By enhancing the material composition of the alloy used for the electrode, a higher wear resistance is achieved. This allows for a smaller diameter of the centre electrode while maintaining the same and even optimizing the service life. In addition, this makes the manufacturer DENSO® less dependent on the highly fluctuating supply of precious metals on the world market. .

DENSO® has marked the new version with an underscore to distinguish these running change spark plugs from the previous range.
This is a "running change" - meaning that the new and old versions merge seamlessly. Mixed installation is therefore not a problem.

The GE3-5 and GK3-5 spark plugs are already being supplied with the new improved alloy.

According to DENSO®, the variants will follow chronologically in the future: GI3-1, GL3-1, GT3-1, GI3-3 & GL3-3.
Following that, the changes will also be applied to the GE3-1, GK3-1, GE5-1, GE2-1, GK3-1 and GN3-1A

16.03.2020 - COVID-19 Information

Dear customers, suppliers and partners

We all are in the face of an unprecedented challenge at the moment. Of course, you are worried about how we deal with the current COVID-19 situation. ONERGYS has already taken far-reaching measures to prevent further spread and contamination. The health and safety of our employees, customers and partners remain our top priority.

We are available and able to deliver!  

Despite numerous restrictions, we have managed to keep our shipping and service at the usual high level and protect the employees at the same time. Our office activities were moved to the home office as far as possible. In our business premises and our shipping warehouse, the hygiene and behavioral instructions published by the Federal Centre for Health continue to apply. Here we work with a minimum staffing level in order to ensure the dispatch and the processes as usual.

Due to our high storage capacities, we are able to deliver incoming orders as usual and without any problems at the moment. The internal processes function smoothly. Should this situation change, we will inform you immediately.

Please note that due to the current situation, there may always be a delay in the shipping route or the tracking process of your order. Our shipping partners report a 100% availability at the moment.

In part, due to the high volume of shipments, there are delays in delivery and customs clearance at borders worldwide. This also applies to delivery by our suppliers. We are in close contact here to ensure continuous delivery, so that we can continue to supply the usual spare parts in sufficient quantities. Within the scope of possibilities, we have increased our safety stock.

 "First come, first served!"

Incoming orders are processed according to the "first come, first served" principle, i.e. in the chronological order of their incoming dates. Please place your order at to get an order/transaction number directly. On our webshop you will also find the current availability -> Green traffic light = item is available from stock. Yellow traffic light = item has been ordered from our supplier, goods receipt is expected. In case of doubt, we recommend the shipping method "Express" if you need to order items in a time-critical manner.

We have no influence on any delivery delay by the shipping service providers. However, we make sure that your orders leave our warehouse on time. Should there nevertheless be due to the occurrence of force majeure or problems with delivery by the forwarding agents, ONERGYS shall not be liable for any delays or any additional costs or damages incurred as a result, since delivery is the responsibility of the shipping partner falls.

Suppliers and logistics partners struggle with restrictions and high volumes

The logistics situation is stable. Except for restriction from a few postcode areas in Europe, there are no areas that could not be served at present. The situation at border crossings has been partly changed by controls, with no restrictions on the movement of goods. Border closures, entry bans, restrictions at local, regional and international levels can make deliveries and pick-ups more difficult or, in exceptional cases, no longer possible. 

Please allow enough time for a delay in delivery!

The goods leave our warehouse on time, but the running times are extended and there may be delays. We are not going to make firm deadlines in the current situation, as we cannot guarantee them. Of course, in cooperation with our partners and suppliers, despite adverse circumstances, we try to get your shipment on its way in the usual ONERGYS quality and speed. Please check in advance whether a smooth delivery is currently possible for you. Please also help us with a telephone number and a contact person for making communication and coordination possible in context of delivery. 

Please contact us!

We are available by phone and email, as usual. If you are unable to reach your personal contact, please contact one of the following central e-mail addresses:
