Today, the sustainable development of the country’s economy depends directly on the energy sector. Modern society and industry are completely dependent on a stable power supply and today, energy is considered the most important component of the life support of the country’s population. The country’s electrical power industry needs new large-scale investments and promising development. To do this, in the near future, the state needs to consider ways to solve problems that have arisen. The purpose of the study is to consider the elements of public administration and the evolution of the energy supply system in Kazakhstan, as well as public administration systems in other countries, such as the USA, Norway, Great Britain, and the Russian Federation. In the article, with the help of SWOT analysis and scientific analysis, the factors of development of the country’s energy industry are considered.","PeriodicalId":52299,"journal":{"name":"Polityka Energetyczna","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69552698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The seventh goal is aimed at providing the sustainable development of energy systems whilst taking into account these dimensions. To assess the development trends of national energy systems within the framework of the global energy agenda, certain methods of quantitative measurement have acquired particular relevance. Approaches to assessing energy security mainly depend on the in - terpretation of the “energy security” concept.

In economic and financial studies of the project investment preparation stage, the options of using capital and paying interest will be taken into account to minimize risks and increase the project’s ability to pay due debts. However, it is difficult to know which loan repayment option is the most beneficial for the project and when the risk is for the project in the context of debt repayment. The current economic and financial analysis of the project mainly focuses on determining the feasibility of the project through basic parameters, such as net present value (NPV), benefit – cost – ratio (B/C), internal rate of re - turn (IRR), profitability index (PI) and payback period (PP). These parameters do not indicate the most difficult time to pay off the project’s loans. This paper analyzes two options for repayment of long-term loans in Vietnam using the case study of Son La hydropower plant to clarify the above difficult times and recommend a suitable repayment plan for the power project.

However, differing perspectives and priorities among JOA participants can lead to disputes and operational inefficiencies. To ensure smooth operations and prevent potential conflicts, it is crucial that JOAs are precisely drafted and clearly define the scope and limits of joint activities. This paper examines the practical implications of sole-risk and non-consent clauses in JOAs, which aim to regulate unilateral actions by individual parties and maintain the collaborative spirit of the agreement. Sole-risk and non-consent clauses can effectively prevent disputes by specifying the boundaries of joint operations and individual party responsibilities. They ensure that parties do not extend the scope of the JOA to activities that are meant to be conducted independently, thereby preserving the agreement’s original intent. Nevertheless, these clauses must be narrowly defined in order to avoid inadvertently restricting the flexibility and collaboration that are the hallmarks of JOAs. This study analyzes various cases in which sole-risk and non-consent clauses have been implemented and evaluates their effectiveness in preventing disputes and promoting efficient joint operations. The findings reveal that when carefully drafted and unambiguously","PeriodicalId":52299,"journal":{"name":"Polityka Energetyczna","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44776080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
