Resolution ARG/gas 119/10 - “Consolidating Act on the regulation of the quality and the tariffs for natural gas storage services for the 2011-2014 period (TUSG): approval of part II - Regulation of natural gas storage service tariffs for the regulatory period 2011-2014 (RTSG)”, measures on the transitory payment for the gas transportation metering service for 2011.
With this resolution, published on 5 August 2010, the Electricity and Gas Authority established the calculation criteria for the storage tariffs for the third regulatory period (1 January 2011-31 December 2014).
The valuation of the net capital invested (RAB) is based on the revalued historic cost method. The return rate (WACC) of net capital invested is set at a real rate of 6.7% before taxes.
The incentives for new investments were confirmed and provide for a higher return compared to the base rate (WACC), amounting to 4% for a period of eight years for extending existing capacities and for a period of 16 years for developing new fields. The revenues associated with new investments are paid starting from the second year following the one in which the costs were incurred (“spending”) and are guaranteed regardless of the volumes transported.
The method for updating the price cap tariffs is applied to revenue relating to operating costs and is equal to approximately 18% of the revenues in question, which are updated for inflation and decreased by an annual recovery coefficient set at 0.6% (2% on operating costs and 1.5% on amortisation and depreciation in the previous regulatory period). The revenue components which are related to returns and amortisation and depreciation are determined on the basis of the annual update of net capital invested (RAB). Specifically, in the third regulatory period, the amortisation is subtracted from the price-cap mechanism.
With this resolution, for the purposes of applying the tariffs, the calendar year is taken as a reference rather than the thermal year and the single tariff is confirmed nationally along with the revenue equalisation mechanism.
