| 1 The income from auctions to cover the chargeable costs of the transmission system is allocated to the segments in accordance with the regulatory requirements. | ||||
| 2 The ITC compensation for grid usage and active power losses corresponds to net income. Supervision charges paid to ElCom and to the Swiss Federal Office of Energy (SFOE) amounting to CHF 6.2 million (previous year: CHF 6.1 million) were deducted from the gross income of CHF 19.1 million (previous year: CHF 41.8 million) on a pro rata basis. | ||||
| 3 Active power losses are a separate internal balance group. As a result, internal transactions occur between the general ancillary services/imbalance energy and active power loss segments. | ||||
Swissgrid was able to reduce the tariffs for general ancillary services/imbalance energy and active power losses in the reporting year and, as expected, reported lower net turnover than in the previous year. In addition to lower tariff income in the general ancillary services/imbalance energy (CHF –108.1 million) and active power loss (CHF –76.2 million) segments, the decrease in net turnover is attributable to lower revenue from balance group imbalance energy (CHF –76.7 million) and lower income from auctions to cover the chargeable costs of the transmission system (CHF –70.5 million). The decrease in tariff income is attributable to the lower general ancillary services tariff (from 0.75 to 0.55 cents/kWh) and the lower individual ancillary services tariff for active power losses (from 0.64 to 0.35 cents/kWh). The decrease in revenue from balance group imbalance energy is attributable to the lower costs for ancillary services energy, as these costs are passed on to the balance groups. In accordance with ElCom’s instructions, the income from auctions received in the reporting year had to be used to cover the chargeable costs and to maintain or expand the transmission system (previous year: income from auctions was used exclusively to cover the chargeable costs). This resulted in lower income from auctions to cover the chargeable costs compared to the previous year.
Net proceeds from congestion management
The net proceeds from congestion management received by Swissgrid in the financial year, referred to as income from auctions, and their use can be broken down as follows:
| In millions of CHF | 2025 | 2024 | ||
|---|---|---|---|---|
| Income from auctions received by Swissgrid | 428.0 | 324.8 | ||
| Used for reduction of the chargeable grid costs | 271.2 | 324.8 | ||
| Used for grid investments | 156.8 | – |
The use of income from auctions is determined annually by ElCom.
