forecasted contracted capacity at entry and exit points and associated assumptions; the quantity and the direction of the gas flow for entry and exit points and associated assumptions, such as demand and supply scenarios for the gas flow under peak conditions; the structural representation of the transmission network with an appropriate level of detail; additional technical information about the transmission network, such as the length and the diameter of pipelines and the power of compressor stations. b the following information: the allowed or target revenue, or both, of the transmission system operator; the information related to changes in the revenue referred to in point (i) from one year to the next year; the following parameters: types of assets included in the regulated asset base and their aggregated value; cost of capital and its calculation methodology; capital expenditures, including: methodologies to determine the initial value of the assets; methodologies to re-evaluate the assets; explanations of the evolution of the value of the assets; depreciation periods and amounts per asset type. operational expenditures; incentive mechanisms and efficiency targets; inflation indices. the transmission services revenue; the following ratios for the revenue referred to in point (iv): capacity-commodity split, meaning the breakdown between the revenue from capacity-based transmission tariffs and the revenue from commodity-based transmission tariffs; entry-exit split, meaning the breakdown between the revenue from capacity-based transmission tariffs at all entry points and the revenue from capacity-based transmission tariffs at all exit points; intra-system/cross-system split, meaning the breakdown between the revenue from intra-system network use at both entry points and exit points and the revenue from cross-system network use at both entry points and exit points calculated as set out in Article 5. where and to the extent that the transmission system operator functions under a non-price cap regime, the following information related to the previous tariff period on regarding the reconciliation of the regulatory account: the actually obtained revenue, the under- or over-recovery of the allowed revenue and the part thereof attributed to the regulatory account and, if applicable, sub-accounts within such regulatory account; the reconciliation period and the incentive mechanisms implemented. the intended use of the auction premium. c the following information on transmission and non-transmission tariffs, accompanied by the relevant information related to their derivation: where applied, commodity-based transmission tariffs referred to in Article 4(3); where applied, non-transmission tariffs for non-transmission services referred to in Article 4(4); the reference prices and other prices applicable at points other than those referred to in Article 29. 2 In addition, the following information shall be published with regard to transmission tariffs: a explanation of the following: the difference in the level of transmission tariffs for the same type of transmission service applicable for the prevailing tariff period and for the tariff period for which the information is published; the estimated difference in the level of transmission tariffs for the same type of transmission service applicable for the tariff period for which the information is published and for each tariff period within the remainder of the regulatory period. b at least a simplified tariff model, updated regularly, accompanied by the explanation of how to use it, enabling network users to calculate the transmission tariffs applicable for the prevailing tariff period and to estimate their possible evolution beyond such tariff period. 3 For the points excluded from the definition of relevant points referred to in point 3.2(1)(a) of Annex I to Regulation (EC) No 715/2009, the information on the amount of forecasted contracted capacity and the forecasted quantity of the gas flow shall be published as set out in point 3.2(2) of Annex I to Regulation (EC) No 715/2009.
