The cost of electricity has increased steadily over the past decade. One of the most demanding items in agriculture for electricity is irrigation. The objective of the study conducted from 2012 to 2014 summarized in this document was to build an energy diagnosis of irrigation installation to offer solutions to farmers to reduce their energy consumption and thus reduce energy bill. In order to build this diagnosis, nine installations equipped with mobile gun were followed during the three years of the project. One of the installations was equipped by pressure sensors to study pressure loss variations during an irrigation campaign. This study has led to simple indicators definition to characterize irrigation installations in terms of energy and to a diagnosis method to help farmers who want to reduce their electrical consumption.
