For the period from 1 January 2023 to 31 December 2023 (from now on: 2023) the Energy Agency has determined the level of eligible costs for electricity operators and, thus, implemented the conditions for setting tariff items for network charges for the use of the electricity system on the basis of the Legal Act on the methodology for determining the regulatory framework and network charges for the electricity system operators.

In setting the regulatory framework for 2023, the Energy Agency addressed in detail the following areas:

• electricity consumption
• planned development of the network infrastructure and quality level of the electricity system operators’ services
• eligible costs of the electricity system operators
• tariff items for network charges by individual demand groups

Setting the regulatory framework

Based on the analysis of the operations of electricity operators in past periods, projections of electricity consumption, and investment plans, the Energy Agency has set the level of eligible costs for both - the TSO and the electricity DSO. The eligible costs of the electricity system operators shall consist of:

• controlled operation and maintenance costs
• uncontrolled operating and maintenance costs
• costs of electricity losses in the system
• costs of flexibilty services
• depreciation costs
• regulated return on assets
• ancillary services costs
• quality of supply
• research and innovation costs
• the impact of investments performance on eligible costs
• incentives

Resources to cover eligible costs are the network charges and other revenues. Deviations from the regulatory framework of previous years and the planned settlement for the current regulatory period are taken into account when determining the resources to cover eligible costs. 

The Energy Agency issued a decision providing a regulatory framework for each electricity system operator, in which it also established tariff items for the network charges, which remain the same as the tariffs for 2022. It also published the network charges tariff items in the Official Gazette of the Republic of Slovenia, No. 161/22.
