| 1 From the 2025 financial year onwards, the costs for grid enhancements are included in the solidarised costs in accordance with the provisions of the revised Electricity Supply Act (in force since 1 January 2025). | ||||
| 2 The costs for reactive energy/voltage maintenance are allocated pro rata to general ancillary services/imbalance energy and reactive energy in accordance with the regulatory requirements. | ||||
| 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. | ||||
Lower market prices, optimised procurement processes and the use of the «Optimizer Autopilot» for control energy led to lower costs for ancillary services energy (CHF –88.7 million) and for active power loss procurement (CHF –71.1 million). The number of national redispatch measures also declined thanks to targeted measures, leading to a decrease of CHF 36.9 million in the costs for national redispatch.
