Introduction. In recent years, the issue of the need to make decisions regarding hydraulic structures of hydroelectric power plants (hereinafter referred to as GTS HPP) that are in operation, the estimated service life of which has ended, has become relevant.

Aim. To focus attention on the lack of norms and rules for establishing the designated period of operation of hydraulic structures, on the importance of ensuring regulatory regulation by creating rules for determining the design service life and designated period of operation, criteria for the possibility of their extension, and also to outline an optimal approach to managing the period of operation of hydraulic structures of hydroelectric power plants during their operation.

Materials and method. Federal laws and other regulatory legal acts are considered for the presence in them of provisions and requirements for the purpose of service life and period of operation, criteria for the possibility of extending the designated period of operation of GTS facilities for various purposes, including GTS hydroelectric power plants. According to SP 58.13330.2019 "Hydraulic structures. The main provisions. Updated version of SNiP 33-01-2003" the assigned estimated service life of the first and second class GTS is 100 years, the third and fourth class GTS is 50 years. This norm was established in 2013. The terms and definitions of service life, designated period of operation.

Results. An analytical review is provided on the state of regulatory support in the Russian Federation in order to determine the rules for designate period of operation of hydraulic structures, information on the practice of decision-making abroad on managing the designated period of operation of hydraulic structures, their conservation, reconstruction or liquidation. The experience of managing the designated period of operation of nuclear power plants is considered. Proposals have been formulated for managing the established period of operation of hydraulic structures of hydroelectric power stations when the service life of hydraulic structures of hydroelectric power stations is exceeded.

 Conclusions. Proposals have been formulated to ensure regulatory regulation for the purpose of determining the period of operation, criteria for the possibility of extending the period of operation, and managing the designated period of operation of hydraulic structures of hydroelectric power stations during their operation.
