Abstract

In this paper, the impact of the adoption of combined-cycle gas-turbine (CCGT) power generation on the Italian energy market is assessed. The study is developed by using the data on new CCGT installations foreseen by the Italian system operator (Gestore della Rete di Trasmissione Nazionale, GRTN). The generation companies (GenCos) participate to the market with their conventional and/or CCGT power plants, through an incremental cost based-supply bid for every generating unit. The CC power plant incremental costs are evaluated and implemented in a market model representing the day ahead energy market (DAEM) structure, as stated by regulator, in order to assess energy price and dispatched power. In particular, the simulation tool is able to maximize the social welfare with a double side multistage bid structure.
