Процесс энергоперехода в мире идет неравномерно и оказывает существенное влияние на социально-экономические процессы во всем мире. Инвестиции в энергетические проекты необходимо планировать по многим причинам, в том числе экономическим и финансовым. Настоящая статья предлагает подход к планированию инвестиций в электростанции, работающие от устойчивых источников электроэнергии, в том числе СЭС, ВЭС, ГЭС и АЭС. Несмотря на важность данной темы, до сих пор не так много работ в этой области. На основе предложенной модели анализа временных рядов проведен расчет необходимых инвестиций для достижения принятых планов в двух странах BRICS: России и Бразилии. Исследование выявило сходства и различия энергетических систем двух стран, а также динамику генерации электроэнергии от устойчивых источников. Бразилия является одним из мировых лидеров по доле устойчивых источников энергии в энергобалансе и продолжает быстрое развитие почти по всем видам устойчивой энергетики. Россия также показывает высокую динамику развития по отдельным видам устойчивой энергетики. Подход, изложенный в статье, показал эффективность и может применяться для прогнозирования генерации электроэнергии и инвестиций в строительство необходимых мощностей сроком на 1–3 года.</p></abstract><trans-abstract xml:lang="en"><p>Nowadays power systems of countries undergo serious changes caused by passing to sustainable electric power sources. The process of power transfer in the world is rather irregular, which affects social and economic processes all over the world. Investment into power projects shall be planned due to numerous reasons, including economic and finance ones. This article provides an approach to planning investment into electric power stations working on sustainable sources of electric power, such as SES, VES, GES and AES. In spite of the problem importance, not so many works have been published in this field. On the basis of advanced model of analyzing time series estimation of necessary investment was done to reach the set goals in two BRICS countries: Russia and Brazil. The research showed similarities and differences in power systems of two countries and dynamics of electric power generation on sustainable sources. Brazil is one of global leaders by the share of sustainable sources of energy in the power balance and it continues fast development in all types of sustainable power. Russia also shows high dynamics of development in certain types of sustainable power engineering. The approach demonstrated in the article proves its effectiveness and can be used to forecast electric power generation and investment into building necessary capacities for the period of 1-3 years.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анализ временных рядов</kwd><kwd>нейронные сети</kwd><kwd>прогнозирование генерации</kwd><kwd>прогнозирование инвестиций в электроэнергетику</kwd><kwd>СЭС</kwd><kwd>ВЭС</kwd><kwd>ГЭС</kwd><kwd>АЭС</kwd></kwd-group><kwd-group xml:lang="en"><kwd>analysis of time series</kwd><kwd>neuron nets</kwd><kwd>generation forecasting</kwd><kwd>investment into electric power engineering forecasting</kwd><kwd>SES</kwd><kwd>BES</kwd><kwd>GES</kwd><kwd>AES</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Санкт-Петербургского государственного университета, проект № 123042000120-3.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">В Германии отменили госпрограмму по отказу от атомной энергетики. – URL: https://oilcapital.ru/news/2025-05-21/v-germanii-otmenili-gosprogrammu-po-otkazu-otatomnoy-energetiki-5395676 (дата обращения: 19.07.2025).</mixed-citation><mixed-citation xml:lang="en">V Germanii otmenili gosprogrammu po otkazu ot atomnoy energetiki [Germany Cancelled State Program on Rejection Nuclear Power Engineering].
