Information regarding planned cost structure of distribution system operators, imposed by the National Energy and Utilities Regulatory Commission (NEURC) together with distribution tariffs. The data is itemized by distribution system operators with reference to respective NEURC resolutions by which cost structure is imposed. The costs are divided into three levels, so that by summing lower-level cost items one can obtain higher-level cost item. For the purposes of data unification, the wording of some cost items were changed without changing their actual meaning.

Information on the structure of tariffs for electricity distribution services according to the COST+ methodology, which is set by the NEURC together with tariffs for electricity distribution. Key indicators are: cost components that are included in the tariff calculation and costs in the current tariff.

As of 2024, 6 DSOs operate according to the "COST+" methodology, the rest – using the Regulatory Asset Base (RAB regulation).

Information on the structure of tariffs for electricity distribution services based on the Regulatory Asset Base (RAB), which is set by the NEURC together with tariffs for electricity distribution. Key indicators are: cost components that are included in the tariff calculation and costs in the current tariff.

RAB regulation is a system of long-term tariff formation, the main purpose of which is to attract investment in the development and modernization of electrical networks and stimulate the efficiency of DSOs' costs. Such regulation helps to reduce the cost and shorten the period of connection to the power grids of new consumers, improve the quality of the distribution service to existing consumers and reduce the loss of electricity in the networks.

As of 2024, 26 DSOs operate using RAB regulation, the rest - according to the "COST+" method.
