theoretical flow demanded was 65 l s , excluding zero, ensuring its operation when the farmer
irrigates. The number of working hours estimated was over 3,000, always working under best efficiency conditions, and generating more than 12 MWh. The diesel generator emissions, considering 2,6 kg eCO2 l-1 (MITECO, 2018) of diesel, amount to 9.6 t eCO2 that will be completely avoided using the proposed solution. The payback period estimated was five years. The construction of this plant will take place during March and April of the current year.
MHP is a potentially viable solution for improving the energy efficiency on the irrigation sector. Its usage at farm level to replace diesel generators seems to be a technically and economically effective way to, partially or completely, avoid GHG and air pollution emissions without interrupting irrigation activity. Future research will use the results of this experimental plant to investigate the long-term performance of MHP technology in this setting.
