According to the contract signed in November 2016, Turboatom JSC will manufacture and supply 7 hydraulic turbines PL 15-GK-600 in a complete set for the reconstruction of two power units of the Kanevskaya HPP.

This contract is the result of the first joint participation of "Turboatom ", which acted as the general contractor, and its partners - SE "Plant " Electrotyazhmash "(delivery of seven generators under the contract) and the Consortium " NPO Ukrhydroenergostroy "(delivery under the contract for eight auxiliary systems of hydraulic units and equipment installation supervision). The agreement on cooperation between the partners was signed in October 2015. The contract is for several years, the final delivery date for all equipment is the end of May 2021.

The guide vane regulates the flow of water through the turbine, and also stops the access of water to the impeller and to the tailwater. Structurally, it is of a conical type with 24 blades. The guide vane includes: an outer and an inner ring, a regulating ring, blades with swing mechanisms, etc. The vanes are controlled by two servomotors through the vane rotation mechanisms and the control ring.

The rotation of the guide vanes is carried out synchronously with the rotation of the impeller blades in a combinatorial relationship providing shockless flow on the impeller blades and, as a consequence, the optimal efficiency of the turbine.
