Актуальность обусловлена необходимостью обоснования для принятия управленческих решений, нацеленных на отраслевые эффекты. Научная новизна заключается в применении комплексного сравнения между различными отраслями проекта. Цель исследования — определение целесообразности доведения уровней воды в Чебоксарском и Нижнекамском водохранилищах до проектных отметок. Рассмотрена эффективность проекта в ержек с их количественной оценкой по сценариям.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В качестве исходных материалов использованы данные технико-экономической оценки завершения строительства Чебоксарской ГЭС, официальные сведения о функционировании Волжско-Камского каскада, а также нормативно-правовые и стратегические документы. Применены методы экономической оценки инвестиционных проектов, сценарного анализа и дисконтирования.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что доведение уровней воды до проектных отметок приводит к увеличению выработки и располагаемой мощности гидроэлектростанций, устранению ограничений судоходства на Единой глубоководной системе, снижению эксплуатационных затрат на дноуглубительные работы и улучшению гидрологического и экологического состояния водохранилищ. Для всех рассмотренных сценариев получен положительный интегральный межотраслевой эффект, существенно превышающий показатели при сохранении непроектных уровней.</p></sec><sec><title>Выводы</title><p>Выводы. Результаты исследования свидетельствуют о положительных межотраслевых эффектах доведения водохранилищ до проектных отметок. Проект целесообразен и подлежит практической реализации.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The study aims to assess the effectiveness of raising the Volga-Kama cascade to its design levels. The relevance stems from the need to provide a basis for management decisions aimed at achieving sector-wide effects. The scientific novelty of this research lies in a comprehensive comparative analysis of various aspects of the project. The aim of the study is to determine the feasibility of raising water levels in the Cheboksary and Nizhnekamsk reservoirs to their design levels. The study examines the project’s effectiveness in terms of key benefits and costs, with a quantitative assessment of these across different scenarios.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The source materials used include data from the technical and economic assessment of the completion of the Cheboksary Hydroelectric Power Station, official information on the operation of the Volga-Kama cascade, as well as regulatory, legal and strategic documents. Methods of economic evaluation of investment projects, scenario analysis and discounting were applied.</p></sec><sec><title>Results</title><p>Results. The results demonstrate that restoring design water levels leads to a significant increase in hydropower generation and available installed capacity, removal of navigation depth constraints on the Unified Deep-Water System, reduction of recurrent dredging expenditures, and improvement of hydrological and ecological conditions in the reservoirs. For all considered scenarios, the aggregated intersectoral effect remains positive and substantially exceeds the outcomes associated with continued operation at non-design water levels.</p></sec><sec><title>Conclusions</title><p>Conclusions. The findings of the study indicate that raising the reservoirs to their design levels will have positive cross-sectoral effects. The project is feasible and should be implemented.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эффективность</kwd><kwd>эффект</kwd><kwd>инвестиционный проект</kwd><kwd>сценарий</kwd><kwd>гидроузел</kwd><kwd>водохранилище</kwd><kwd>каскад</kwd><kwd>уровень воды</kwd><kwd>проектная и непроектная отметки</kwd><kwd>отрасль</kwd><kwd>выгоды</kwd><kwd>издержки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>the efficiency</kwd><kwd>impact</kwd><kwd>investment project</kwd><kwd>scenario</kwd><kwd>hydropower plant</kwd><kwd>reservoir</kwd><kwd>cascade</kwd><kwd>water level</kwd><kwd>design and non-design water level</kwd><kwd>industry</kwd><kwd>advantages</kwd><kwd>and costs</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Upadhyay D., Bhatia U.
