Intensive modernization and reconstruction of the energy sector takes place throughout the
world. The EU climate and energy policy will have a huge impact on the development of the energy
sector in the coming years. The European Union has adopted ambitious goals of transforming
towards a low-carbon economy and the integration of the energy market. In June 2015, the G7 countries
announced that they will move away from coal fired energy generation. Germany, which
has adopted one of the most ambitious energy transformation programs among all industrialized
countries, is leading these transformations. The long-term strategy, which has been implemented
for many years, allowed for planning the fundamental transformation of the energy sector; after the
Fukushima Daiichi nuclear disaster, Germany opted for a total withdrawal from nuclear energy and
coal in favor of renewable energy. The German energy transformation is mainly based on wind and
solar energy. Germany is the fifth economic power in the world and the largest economy in Europe.
Therefore, the German energy policy affects the energy policy of the neighboring countries. The
article presents the main assumptions of the German energy policy (referred to as Energiewende).
It also presents the impact of changes in the German energy sector on the development of energy
systems in selected European countries.
Energy security is one of the most frequently analysed phenomena in the energy markets. Great variety of scientifc efforts should have indicated clear definition of the phenomenon. However, those studies highlighted more than 80 different definitions of what energy security really is. Due to the fact, that energy security is analyzed by different scientific disciplines, studies have provided a comperehensive reflection on the phenomenon.
The main objective of this paper is of the theoretical nature and focuses on showing energy security externalities. Author delivers an integrative review focusing on existing literature referring to the analyzed phenomena. Energy security is though studied only from the perspective of economics therefore interdisciplinary studies are out of the study scope. The reason for such scientific procedure stem from a belief that each discipline approach is different in terms of concepts, research methods and though results that are obtained. Therefore without undermining high value of interdisciplinary approaches to energy security, author decided to concentrate solely on economic perspective, which in energy security studies seems to be underestimated. Such approach in author’s belief helps achieve theoretical clarity of the below given analysis.
Presented paper is of the theoretical nature and focuses on showing energy security externalities. Critical literature review shows the literature mainstream in which energy security externalities are
The paper presents brown coal as one of the two basic domestic energy raw materials apart from hard coal. Historically, the use of brown coal in Poland is primarily fuel for the power plants. It was used for the production of lignite briquettes in small quantities and as fuel for local boiler houses and as an addition to the production of fertilizers (Konin and Sieniawa). At present, after changes in the case of the quality of fuels used in local boiler plants, brown coal remains as a fuel for the power plants in almost 100%. Currently, the brown coal industry produces about 35% of the cheapest electricity. The cost of electricity production is more than 30% lower than the second basic fuel – hard coal. The existing fuel and energy complexes using brown coal, with the Bełchatów complex at the forefront, are now an important guarantor of Poland’s energy security. In contrast to the other fuels such as: oil, natural gas or hard coal, the cost of electricity production from brown coal is predictable in the long term and almost insensitive to fluctuations in global commodity and currency markets. Its exploitation is carried out using the high technological solutions and respecting all environmental protection requirements, both in the area of coal extraction and electricity generation. Importantly, the fuel and energy complexes using brown coal showed a positive profitability so far and generated surpluses enabling the financing of maintenance and development investments, also in other energy segments. In particular, the sector did not require and has yet not benefited from public aid in the form of, for example, subsidies or tax concessions. Polish brown coal mining has all the attributes necessary for long-term development to ensure the country’s energy security. The document which is a road map for the brown coal industry is the Program for the Brown Coal Mining Sector in Poland adopted by the Council of Ministers on May 30, 2018. The Program covers the years 2018–2030 with a perspective up to 2050 and presents the development directions of the brown coal mining sector in Poland together with the objectives and actions necessary to achieve them. The Program presents a strategy for the development of brown coal mining in Poland in the first half of the 21st century. Possible scenarios have developed in active mining and energy basins as well as in new regions with significant resources of this mineral. This is to enable the most efficient use of deposits in the Złoczew and Konin regions as well as the Gubin and Legnica brown coal basins, and then deposits located in the Rawicz region (Oczkowice) as well as other prospective areas that may eventually replace the existing active mining and energy areas. This will allow power plants to continue to produce inexpensive and clean electricity, using the latest global solutions in the field of clean coal technologies.
The article presents the author’s considerations on the significance of the investment package diversifying natural gas supplies as part of the Northern Gate in ensuring Poland’s energy security. Data found in literature concerning the possibilities of importing the raw material by sea (terminals, gas pipelines) includes investments at various stages of concept development and construction. However, these documents lack cohesive information about a full investment package being implemented. The author has thus attempted at creating variants concerning the diversification capacities of the Republic of Poland in reference to several key offshore and onshore projects. A problem has therefore been formulated: To what extend will the Northern Gate investment package increase Poland’s energy security as a result of increased supply of natural gas from the sea? To answer this questions, researchers were forced to verify their working hypothesis which assumed that Northern Gate investments including a comprehensive package of projects had the potential of significantly improving the level of energy security in Poland by extending the possibility of importing natural gas. To solve the problem and verify the hypothesis, the researchers applied systemic analysis, deduction and variant analysis, which were used to estimate the possible import capacities of the raw material by sea. As a result of the works, the researchers created four variants including various investment projects assuming the import of 7.75 m3 to 30,95 B m3 of natural gas a year by sea. The variant which was adopted as the most probable indicates the possibility of importing 17.75 through 22.75 B m3 of gas a year, which is 111% of the average annual demand in Poland.
The energy security of the European Union is still a concept, rather than the actual action. It was confirmed by legal regulations that give Member States the possibility of individual control of energy security. Furthermore, EU Member States can perform unilateral energy policy, which is often in the interest of the most powerful countries. The concept of energy solidarity, solidarity mechanisms of energy flows directly from the Treaty of Maastricht. This was intended to help to increase energy security, and above all, its construction at the EU level. The functioning of the European Communities and the European Union is showing that the goal of building energy security of the European Union is still in the process of creation and still remain a certain course of action. Following th energy crisis of 2009 we can observe discussion about the concept of energy union, as a way to build energy security of the European Union. Currently, its energy security is limited to the definition adopted by the European Commission and activities aimed at the development of energy infrastructure of Community interest, which contributes to improving EU energy security. The aim of this article is analyze the concept of energy union and attempt to answer the question whether it has a real chance of success, and whether the concept of the proposed shape will be effective and necessary. These questions are important because of we can observe discrepancies between the regulations, promotion of building a common energy security and the practical action of individual Member States of the European Union.
The issue of energy security was the subject of research in the 1970s when the oil crisis of 1973 significantly affected the economic stability of hundreds of companies and ordinary citizens in the United States and Western Europe. One of the first researchers of energy security was Mason Willrich who, considering the impact of energy on international politics, national security, the world economy, and the environment in the world, drew attention to the issues of “security of supply” and “security of demand” as fundamental to ensure energy security. The concept of “energy security” involves the comprehensive implementation of political, economic, environmental, technological, and social measures to strengthen the internal subjectivity of the state and limit opportunities for external influence. Subsequently, numerous researchers have expanded the understanding of energy security to environmental sustainability and energy efficiency). The presented scientific work is focused on the analysis of state management decisions for ensuring the energy security of Ukraine. The authors also trace vulnerabilities in various energy systems, including energy infrastructure, energy services, and renewable energy sources. The decline in energy demand due to the COVID-19 pandemic in Ukraine has created a dilemma: state support for renewable energy production (RES), which generates rising producer prices, or reduced energy intensity of GDP and stimulated production of cheap nuclear energy. A comprehensive scientific analysis of the solution to this dilemma is the purpose of the presented work.
Due to unfavorable factors, dangerous conditions occurred in the delivery of electric energy in Poland. This was the most serious incident of its kind since the 1980’s. Such a serious incident raised concern about the safety of the electric power system in the summer and led to the formulation of conclusions for the future. In this article, the author analyses the conditions, which caused that situation. Poland was experiencing a doubt in August 2015, which along with an extremely high maximum daily temperature created remarkably unfavorable conditions for power plants and decreased the capacity of overhead power lines. Such unfavorable metrological conditions occurred not only in Poland, but also in Central-Eastern and Western Europe. It is worth emphasizing that the safety of electric energy delivery was endangered only in Poland. The improper renovation and upkeep policies, as well as unplanned outages in power plants caused a significant decrease of available power in the National Electric Power System. Unscheduled flows between Germany and Poland ruled out the possibility of importing electric energy at such a critical time. The author presents the correlation between the maximum daily air temperature in the sweltering heat and an increase in the demand for electric energy. Overall, unfavorable conditions posed a threat in the delivery of electric energy in Poland. In this article, the author draws attention to the report from the Supreme Audit Office (Najwyższa Izba Kontroli – NIK) from 2014, which predicted such a dangerous situation. Unfortunately, that report remained unnoticed. The author formulated appropriate solutions in order to increase the safety of electric energy delivery in the summer and to prevent such occurrences in the future.
The implementation of micro scale combined heat and power systems is one of the ways to improve the energy security of consumers. In fact, there are many available large and medium scale cogeneration units, which operate according to the Rankine Cycle. Due to European Union demands in the field of using renewable energy sources and increasing energy efficiency result in the importance of additionally developing systems dedicated for use in residential buildings, farms, schools and other facilities. This paper shows the concept of introducing thermoelectric generators into typical wood stoves: steel plate wood stoves and accumulative wood stoves. Electricity generated in thermoelectric generators (there were studies on both three market available units and a prototypical unit developed by the authors) may be firstly consumed by the system (to power controller, actuators, fans, pumps, etc.). Additional power (if available) may be stored in batteries and then used to power home appliances (light, small electronics and others). It should be noted that commercially available thermoelectric generators are not matched for domestic heating devices – the main problems are connected with an insufficient heat flux transmitted from the stove to the hot side of the generator (caused e.g. by the non -homogeneous temperature distribution of the surface and bad contact between the stove and the generator) and inefficient cooling. To ensure the high efficiency of micro cogeneration systems, developing a dedicated construction both of the generator and the heat source is necessary.
Polish energy security is currently one of the key elements affecting the national security system. Maintaining operational efficiency and the permanent modernization of both, power plants, as well as transformer stations and transmission networks is a starting point of ensuring energy security in our country. This is a significant challenge, taking into account the age of the energy critical infrastructure elements in Poland, as well as the permanent increase of the demand for electricity. This implies a systematic growth of the importance of the issue the country’s energy security. The numerous events and anomalies that accompany our everyday life, such as the storms that passed over Poland on the night of August 11–12, 2017, indicate the considerable sensitivity of the critical energy infrastructure on the impact of various negative factors. The security of Polish critical infrastructure connected with the distribution of electricity is particularly at risk. Therefore, it is desirable not only for current repairs and the modernization of the power system elements, but also for the work related to adapting the infrastructure to current and even forecasted needs, challenges and threats. In the face of the presented research results, the reconstruction of the Polish power system, as well as the implementation of innovative solutions in the production, transmission and distribution of energy seems to be unavoidable. Therefore interdisciplinary research and analyses are recommended, allowing the level security of the critical infrastructure to be increased through the best possible diagnosis of factors that may even slightly threaten this security.
The role and importance of energy security increases with the development of civilization, whose inherent element has become the demand for energy and its carriers. The article discusses the issue of cooperation in the field of energy security in Central Europe at the moment of finishing work on the North-South Corridor, which changes the existing gas architecture in the region. In order to better understand the situation in the region, the energy systems of the Visegrad Group countries, identical to the Central European region, have been analysed, according to the definition of the World Bank and OECD. Considering the historical and geopolitical connections of the Visegrad Group’s fate, it is important to create a common gas market. The physical interconnection of gas systems greatly increases energy security in this region. Moreover, thanks to the construction of LNG terminals in Poland and Croatia, it will be possible to diversify not only the routes, but also the sources of supply of this important raw material.
A lot of interest has recently been put into the so-called ‘virtual cryptographic currencies’, commonly known as cryptocurrencies, along with its surrounding market. The blockchain technology that stands behind them is also becoming increasingly popular. From the perspective of maintaining energy security, an important issue is the process of mining individual cryptocurrencies, which is associated with very high energy consumption. This operation is usually related to the approval of new blocks in the blockchain network and attaching them to the chain. This process is carried out through performing complex mathematical operations by various devices, which in turn require high power and respectively consume a lot of energy. The impact of cryptocurrency miners on the power and energy demand level might gradually increase over time, therefore this issue shouldn’t be ignored. Comparing the above information in parallel with the growing need for providing demand side response (DSR) services in the Polish Power System, raises the question whether devices used for mining cryptocurrencies can be used for the purpose of balancing the power system. This paper presents an analysis of the possibility to provide the demand side response services by groups of cryptocurrency miners users. The analysis was carried out taking basic functional, technological and economical aspects of these devices’ operations into account.
The overriding objective of the National Electric Power System (KSE) is to ensure the security of electricity supply. In summer, the upward trend in the demand for electric energy is caused by, among others, the proliferation of air conditioners. Therefore, the upward trend in summer’s on-peak demand is expected to be maintained. Examples from 2015, 2016 or 2018 indicate that National Electric Power System needs a summer’s on-peak source that will be able to produce electricity regardless of the hydrological conditions. Photovoltaics is a source of energy that can cover the peak demand during sweltering heat. This article briefly characterizes the problem of increasing demand for electricity in summer and uses examples that have taken place in recent years. The main conclusion is the postulate for the extension of photovoltaic power in the National Electric Power System, the purpose of which will be the production of electricity during sweltering heat, covering the peak load in the system. This article presented both the advantages and disadvantages of such a solution. Unfavorable weather conditions (high air temperature, low water level, lack of wind) limit the production of electricity from wind farms or conventional power plants, and also increase transmission losses, which is why photovoltaics is a desirable source from the National Electric Power System’s point of view. The article refers to examples from the Czech Republic and Germany, where a significant installed capacity of photovoltaics enables the stable operation of the power system during sweltering heat. It was also pointed out that the role of photovoltaics in the National Electric Power System is growing, which is consistent with the assumptions of the Polish Energy Policy Project until 2040.
Natural gas plays a significant role in the energy structure of many world economies. Many of them are highly dependent on domestic resources exploitation, other on its deliveries from non-domestic directions. In Poland its importance was relatively low, but in recent years we can observe an increase of interest in this raw material. The aim of the paper is to present the role of natural gas as a primary energy carrier and to determine its impact on the sustainable development and energy security of Poland. The role of gas in the European Union restrictions and development of the domestic economy is also a point. Theoretical deliberations are focused on the most important features of the Polish natural gas market. The article presents the most important national regulations concerning the development of the gas sector in Poland. The amount of natural gas resources are shown as well as indigenous production of the fuel and imports, including the directions from which natural gas is imported. Both political and geographical aspects of the directions of natural gas acquisition are discussed. The level and potential abilities of the diversification of the natural gas supply are discussed. The importance of gas storages in underground gas repositories is underlined. The authors point to the increase in the diversification of raw materials in the structure of electricity, heat production and the transition to pro-ecological fuels.
The paper analyzed the natural gas sector in Ukraine for the period 2000 to 2018. This sector was affected by external factors, such as the crisis which began in late 2008/2009, as well as internal factors, including the situation in Ukraine after 2013 (the Annexation of Crimea). A comparative analysis was also conducted of the natural gas sector in European Union countries and Ukraine – compared the specificity of natural gas consumption in 2018. The analysis (I) examined the demand for natural gas in Ukraine between 2000 and 2018; (II) described changes in sources to cover Ukraine’s gas needs with a particular emphasis on its own production; (III) pointed to the fundamental changes that have occurred in the natural gas supply routes to the Ukrainian sector in recent years; (IV) stressed the growing role of own production in balancing Ukraine’s gas needs; (V) described the role of Ukraine as a transit country for Russian gas to be delivered to EU countries (in recent years, the volume of natural gas transmitted via the Ukrainian transmission system has been around 90 bcm annually); and (VI) looked at the structure of natural gas consumption in the Ukrainian gas sector and how it has changed in recent years. Unlike EU countries, the growing role of own production in balancing Ukraine’s natural gas needs was emphasized, which is consistent with the strategy of the Ukrainian government. Also, attention was drawn to the threats that may significantly reduce the role of Ukraine as an important transit country. The paper also puts forward the most important parameters concerning the underground natural gas storage facilities in Ukraine which is one of the largest in Europe.
