摘要

Under the ambitious targets for a green power system set by the European Council by 20501, the need of new investments in flexible and efficient technologies to support high shares of renewable generation is on the top of the agenda of all national European governments. This study contributes to the current discussion on the economic viability of new investments in electricity storage and transmission line upgrade [1] and the associated environmental impact in terms of changes in CO_2 emissions and renewable power integration [2] [3]. The analysis is based upon a simple model simulating the operation of a transmission line upgrade project. The case study is applied to the Italian power market (IPEX) where prices in different zones differ significantly due to high variation in the share of generation mix across zones and poor interconnections in some areas of the system. The line upgrade investment increases the power capacity between two interconnected zones, thus alleviating intra-zonal congestion. Its operation maximizes spatial arbitrage value by shifting power from the cost-efficient zone (with low marginal generation costs) to the neighbouring zone (with higher marginal costs), up to the interconnection capacity. The investment analysis focuses on the case of Sicily that coincides with the geographical zone of SICI, and the pole of limited production, Rossano (ROSN), that is located in CSUD and is connected to the island through a submarine cable (Fig. 1). This case study is of particular interest because the zone SICI features the highest and more volatile price levels in the country. Moreover SICI is interconnected to the mainland through one single line (Rossano-Rizziconi-Sorgente) which is in the process of being upgraded through a new double-circuit transmission line of 380 kv2, that will increase the transferred capacity between the two areas. Additionally, the potential of wind and solar generation [4] makes this region the potential leading producer of renewables in Italy3.
