摘要：The Network Code on Gas Balancing of Transmission Networks stimulates the development of the wholesale gas market by encouraging balance responsible parties to use standardized balancing mechanisms. To balance their portfolios, balance responsible parties can use renominations of quantities at entry and exit points, trade on a virtual trading point or trade on a trading platform. In the event of a system imbalance, Plinacro, as the operator of the gas transmission system in the Republic of Croatia, activates the balancing energy to return the system within acceptable limits. In accordance with the Rules on the Organization of the Gas Market, the Croatian Energy Market Operator performs a monthly calculation of the daily imbalance charge, trades conducted on the trading platform for balancing activities, a neutrality charge and a charge for deviation from the nominated quantities which have been analysed in this paper based on the case study of a chosen balancing group. The analyses conducted in the paper have shown that the balance responsible party may be entitled to compensation or be liable to pay compensation based on the monthly calculation of the Croatian Energy Market Operator, HROTE, depending on the value of each charge. Plinacro as the forecasting party is preparing a new model for the allocation of gas quantities that will affect the operations of gas suppliers, DSOs and especially BRPs. Based on this analysis, it could be concluded that more accurate estimated consumption for a balancing group leads to cost optimization and a more transparent gas market.
