In July 2022, the Netherlands Authority for Consumers and Markets (ACM) announced that, in 2023, it will give distribution system operators (DSOs) an advance for the high costs connected to grid losses in 2022. Since the DSOs expect to incur high costs connected to grid losses in 2023 as well, due to the high energy prices, ACM plans to give them an advance next year too. ACM decided to do so in order to prevent DSOs from having less room for investments in projects that are crucial for the energy transition as a result of these high costs.
Energy losses occur when transmitting electricity and when converting, for example, high-voltage electricity to low-voltage electricity. Energy losses also occur when transporting natural gas. System operators are responsible for the purchase of electricity and natural gas that is lost during transmission, which are called grid losses. Costs that are incurred for these grid losses are passed on to end-users in the transmission tariffs. ACM calculates these costs on the basis of costs incurred in the past. As historic costs are not a good indicator for the expected costs in 2023, ACM has announced a remuneration. A remuneration usually takes place two years after the costs have been made. ACM has now decided to give system operators next year an advance for the costs related to grid losses in 2022 and 2023. For 2023, this concerns the costs for electricity and natural gas, while for 2022, only the costs for electricity are concerned.
In October 2022, ACM will publish the tariff proposals of the DSOs and TenneT. ACM will announce the 2023 tariffs by late November.
