It was found that the change in the hydrological regime of energy plantations due to climate change did not significantly affect the productivity and water consumption of perennial crops - miscanthus, Jerusalem artichoke, willow. Climate change has had a positive effect on the productivity of annual crops: sorghum +22%, while the water consumption ratio decreased by -30%, and in corn the ratio decreased by 112 l / kg dry matter, respectively 17%, while its productivity increased insignificantly - up to 5%. It was found that the change of hydrological regime due to climate change did not negatively affect the agro-ecological situation in the plantations of the studied crops. The NO3 content in groundwater at the beginning of the growing season was 4.7 - 5.2 mg / l and increased to 7.5 - 7.7 mg / l at the end of the growing season. The leaching of P2O5 was 0.2 to 0.3 mg / L. Only the application of potassium fertilizer increased the content of K2O from 1.4 to 3.5 mg / l at the beginning of the growing season, which did not exceed the limit norms. The change in the hydrological regime did not significantly affect the energy productivity of Jerusalem artichoke, corn, willow, miscanthus - the difference was 1 - 6%. At the same time, sorghum reacted positively to the reduction of moisture in the plantation, which provided an increase in energy productivity by 65 GJ / ha in 2019. and 56 GJ / ha in 2020
