The entire feasibility study is expected to be ready at the end of the year. The first stage of a four-step feasibility study being developed by Greek electricity transmission system operator ADMIE and its Italian peer Terna for the second submarine cable interconnection linking the Greek and Italian energy systems has been completed.
ADMIE and TERNA are exploring the possibility of developing another electricity interconnection via the submarine cable, for additional capacity of between 500 and 1,000 MW. The project is also included in ADMIE’s ten-year network development plan covering 2022-2031 period.
According to the study, the link between Greece and Italy needs to be strengthened in order to enable electricity price convergence between the two countries. Following the launch of the exchange, Greek electricity prices have equaled Italian-zone price levels for about half the time. This period would have been more extensive, but the existing infrastructure’s capacity limits prevented further price convergence.
