Энергоснабжение изолированных территорий в контексте привлечения инвестиций и развития экономики региона

The study analyses energy supply to isolated areas considering the development of priority areas of the regional economy and assessing the dependence between consumer finances and electricity costs. We examined energy supply problems in the example of the Tuva Republic, the Russian region with vast isolated areas and high prices for energy. We explained the reasons for the increase in electricity costs, including small-scale generation sources based on fossil fuels. The limitations of economically substantiated energy transmission at light loads prevent the connection to a centralised energy supply systems in isolated territories, leading to a decentralised energy supply. Thus, we proposed a methodological toolkit for solving the problem of economic substantiation of the dependence between consumer finances and electricity costs, testing it on the example of the gold mining industry. Our hypothesis relies on technological development opportunities in the field of renewable energy sources to reduce the construction and operation costs of generation facilities. Since the economic feasibility of using renewable energy sources for investors is determined by the dependence of consumer finances on energy generation costs, it is necessary to create energy resource structures depending on different basic conditions. For that purpose, we showed the linear dependence of the profitability of gold mining investment projects on electricity costs. The proposed criteria and methods allow determining the threshold values of the economic efficiency of energy services provided by suppliers and energy produced by self-generating facilities. Based on these results, further research can focus on analysing the impact of electricity costs on the financial parameters of projects to apply innovative energy supply schemes and identifying thresholds of the response of profitability to energy costs reduction for different energy consumption projects. © 2020 Institute of Economics, Ural Branch of the Russian Academy of Sciences.

International Transport Corridors of Eurasia and the Silk Road Economic Belt

The paper discusses the interaction of Eurasian Economic Union and the Silk Road Economic Belt within the framework of transport routes and international transport corridors development. Today’s Eurasian international transport corridors are reviewed together with the discussion of rebuild and renovated transport infrastructure, considering corresponding realization issues. The paper gives the perspective of collaboration in the transport section of planned Big Eurasian Partnership, which is virtually realized within the framework of the Shanghai Cooperation Organization

В статье представлен синтез проблем энергоснабжения на примере Республики Тыва как одного из регионов с обширными территориями изолированного энергоснабжения и с высокими ценами на энергоресурсы. Даны причины роста стоимости электроэнергии, в том числе и от источников малой генерации, работающих на ископаемых видах топлива. Показано, что ограниченность границ экономически обоснованной передачи электроэнергии при малых нагрузках является основным препятствием для подключения к централизованным системам энергоснабжения на изолированных территориях и ориентирует на преимущественно децентрализованное снабжение. Предложен инструментарий, в соответствии с которым на примере отрасли золотодобычи проводится экономическое обоснование чувствительности финансовых параметров потребителя к стоимости электроэнергии. Авторская гипотеза основана на возможностях технологического развития в области возобновляемых источников энергии, сопровождающегося снижением стоимости строительства объектов их генерации и их эксплуатации. Обосновано, что поскольку экономическая целесообразность использования возобновляемых источников энергии для инвесторов определяется с учетом степени зависимости финансовых параметров потребителей от существующих затрат на генерацию, требуется формирование структуры источников энергии при различных исходных условиях. Для решения этой задачи представлена линейная зависимость рентабельности проектов золотодобычи от стоимости электроэнергии. Предложенные критерии и методы определения пороговых значений экономической эффективности получаемых энергетических услуг от поставщика и электроэнергии, производимой объектами собственной генерации, позволят на стадии дальнейших исследований производить индивидуальный анализ влияния стоимости электроэнергии на финансовые параметры проектов для применения инновационных схем энергоснабжения и на практике выявлять пороги чувствительности рентабельности к снижению затрат на электроэнергию по проектам с различными объемами энергопотребления
