The TAP (Trans Adriatic Pipeline) is one of the so-called PCIs, the projects considered as priority for the European Union’s energy policy. As it crosses through Italy to reach the markets of Northern Europe, our country should benefit from a whole series of indirect advantages deriving from this infrastructure.#These are linked mainly to the certainty of supplies and the geopolitical and strategic value brought by the TAP, and by the considerable beneficial economic repercussions such as the creation of employment and the impact on the local economy. However, the variables and reasons for economical and geopolitical uncertainty are so numerous that it is impossible to make a precise estimate of the impact that the pipeline would have on energy costs.#While the entirely private funding of the TAP would lead to a 100 percent positive result of a cost-benefit analysis based only on the financial component, the element of social acceptance and its political cost cannot be overlooked by local and national administrators.
