Energy revenue in irrigation systems: A case study

Abstract

Irrigation systems are generally characterized by a greater discharge than that which usually flows in drinking water supply systems. Moreover, they are supplied in limited periods of the year (irrigation periods) and sometimes a pump station with a high level of energy consumption could be needed. Therefore, when the geodetic heads are relevant it is possible to produce hydroelectric energy from these systems. Through the application on a real case study, i.e. an irrigation system managed by Consorzio Valle del Liri in Southern Italy, a simple optimization method of the system efficiency is herein illustrated. This work results in a feasibility study of the investigated system, leading to increasing social and environmental benefits.
