Year: 2024
Type: article
Abstract: The article examines the mechanism and funding of the "green" tariff in Ukraine, whose primary goal is to increase the share of electricity generated from renewable energy sources (RES) in the overall energy system balance. The functioning of the State Enterprise "Guaranteed Buyer" (GarPok), which serves as the main purchaser of electricity under the "green" tariff, is described, along with the sources of funds for the payment of this tariff, such as transmission fees, financial support from the state budget, and revenues from the sale of guarantees of origin. The current state of "green" tariff financing and its associated challenges, including the National Energy Company "Ukrenergo" debt to GarPok and the absence of revenue from the sale of guarantees of origin, are analyzed. The paper also discusses aspects of RES generation exiting GarPok's balancing group, including the opportunities for selling electricity on various markets. The results of an analysis of the efficiency of RES generation in the electricity market are presented, and the minimum green tariff level at which renewable energy generation exits the balancing group of SE "Guaranteed Buyer" is determined. The number and installed capacity of generation facilities operating on the electricity market through traders' balancing groups are also provided. Keywords: Green tariff, renewable energy sources (RES), negative imbalances, positive imbalances, electricity market, energy supply.
