This provision does not apply to investments in tangible and intangible assets made following the development of investment projects related to Regulation (EU) no. 347/2013. The methodology for determination of the initial value of the assets is described in Annex no.2 to the Methodology approved by ANRE Order no.41/2019

Parameters used on revenue aproval for period 01.10.2023-30.09.2024 (iii) OPEX approved for October 2023-September 2024 amount to RON 944.425,68 thousand (iv) Pass-through costs approved for October 2021-September 2022 amount to RON 98.458,81 thousand (v) Incentive mechanisms and efficiency targets Boosting efficiency is achieved by the adjustment of operating costs. According to the methodology, operating costs are established in the first year of a regulatory period and are adjusted in the subsequent years of the regulatory period with the difference between the inflation rate and the annual rate of gas transmission economic efficiency increase. The rate of gas transmission economic efficiency increase reflects ANRE`s estimations regarding possible OPEX savings, without the technological consumption costs, which may be achieved in a year of the regulatory period to improve the economic performance of the licence holder and is established depending on the efficiency target set for a regulatory period. The rate of gas transmission economic efficiency increase ensures a transfer of economic efficiency in favour of the consumers. The rate of gas transmission economic efficiency increase established by ANRE Order 64/2019 for each year of the fourth regulatory period is 1,5%. The inflation rate approved for October 2023-September 2024 is 4,75.
