MODELLING AND BENCHMARK DEVELOPMENT FOR ELECTRICAL ENERGY USE AND ENERGY EFFICIENCY ON NOVA SCOTIA DAIRY FARMS

Abstract

The analysis of energy use on dairy farms faces a number of challenges, based partly on benchmark parameter currently used as a means to quantify energy consumption. This research addresses this issue, using energy audit data obtained from 19 dairy farms in Nova Scotia to produce benchmark parameters that relate energy use to each operational component of the dairy farm. Models were produced on the basis of energy audit data and theoretical performance of each operational component. These models for major energy component were validated using two statistical tools; Coefficient of Efficiency and Index of Agreement. Model approach was used to determine the benchmark parameters. EUI values were computed based on the model developed, audit data and benchmark parameter, resulting in more pragmatic benchmark values. This research also identifies the potential savings from installation of energy efficient technologies suitable for each major energy components.
