The most frequently asked questions about Energy Relax in tranches

The time of procurement is central to the price of energy. The energy price is subject to strong fluctuations in the market depending on various factors such as supply and demand, weather conditions, geopolitical events and other influencing factors. The timing of the deal can have a significant impact on the final price. By cleverly choosing the time of procurement, potential price advantages can be exploited.


The final average price is determined by the volume-weighted procurement price incl. surcharge of all tranches.


Energy Business is BKW's digital customer portal for customers in the free market. With the Relax in tranches product, you can view and purchase the tranches you have procured and those that are still open on Energy Business at any time. In addition, you have access to information on electricity market developments, your contract documents and invoices, as well as your energy purchases/load profile.

When the contract is concluded, your specific reference profile is rolled out over the contract years, i.e. a long-term forecast is created. This profile is divided into the desired number of tranches, which can be procured independently of each other in terms of time. BKW provides you with details of a proven standard procurement strategy. On request, your customer advisor can help you to adapt this strategy to your specific needs.


For customers with a net purchase of less than 2 000 MWh, BKW assumes the risks for any quantity deviations in the supply. However, the customer is subject to a reporting obligation for foreseeable changes in the supply (e.g. addition of PV systems, etc.). For net purchases of more than 2 000 MWh, the costs/revenues incurred for deviations outside the contractually agreed tolerance limits shall be passed on to the customer.


The Relax and Relax in tranches procurement solutions do not offer the option of an open delivery share. If you want to freely combine the share of procurements on the forward and spot market, the Energy Balance product is the right one for you.


No, BKW is one of the few energy suppliers that cover the whole of Switzerland. Our customers are SMEs that are represented in all Swiss cantons such as Zurich, Lucerne, Solothurn, Grisons, Zug, Aargau, St.Gallen, Bern, etc.
