Upper revenue limit

The upper limits for a network operator’s permitted total revenue from network fees (upper revenue limit) are set on the basis of the stipulations in the Incentive Regulation Ordinance. The upper revenue limit is determined by a cost check. In addition to the approved costs (including basic costs, depreciation, calculated return on equity), investment measures, compensation for inflation and the regulatory account are taken into consideration.


Unbundling generally means establishing or boosting the independence of various business areas of a company or a group of companies. This is done due to legal (anti-trust law) and/or regulatory requirements. In the case of so-called grid-based network industries (energy, rail, telecommunications), unbundling focuses on separating the network infrastructure operations from the upstream and downstream value creation stages of the relevant network industry (production/sales)
