“Leaky Bucket” of Kazakhstan’s Power Grid: Losses and Ine ﬃ cient Distribution of Electric Power

: This paper aims to determine and explain the main factors for power losses (the so-called “leaky bucket” e ﬀ ect) in Kazakhstan and the reasons for ine ﬃ cient energy distribution within the country. Energy e ﬃ ciency in Kazakhstan is much lower compared to more economically developed countries. The di ﬀ erences between energy e ﬃ ciency in various regions of Kazakhstan are also signiﬁcant. This article explores the impact of administrative monopoly tari ﬀ s on the regional energy e ﬃ ciency, based on a national study conducted in Kazakhstan in 2017. The purpose of the study was to identify the administrative barriers and their impact on the sustainability of enterprise development. What hinders the distribution of energy resources among di ﬀ erent regions is artiﬁcial barriers in the energy market and the administrative tari ﬀ monopoly for electric power. This leads to the ine ﬃ cient distribution of resources throughout the country. In addition, it is di ﬃ cult to leverage low distribution e ﬃ ciency in the absence of a market. The authors attempt to prove that the magnitude of administrative barriers directly a ﬀ ects the e ﬃ ciency and competitiveness of business, as well as the ﬁnal prices of goods and services for the end consumer. regions and the most signiﬁcant factors behind them. and a high share of overhead costs, the country’s characteristics, i.e., large open areas, low population density, and the total small market capacity, as well as signiﬁcantly varying climatic conditions. Those factors (rent, waybills), which are part of the overall management process, became a prerequisite for business survival in Kazakhstan. The increase of rent and overhead costs in global trade is usually regulated by changes in the pricing policy and the optimization of the entire production process, but in Kazakhstan, low market capacity does not allow for enough turnover and the compensation of costs. In addition, indirect fees for monopolists for services related to energy transmission, as well as bribes, account for a signiﬁcant share of trade business costs. Practice shows that, as the economic situation deteriorates,


Introduction
Kazakhstan's energy-oriented economy is the richest and largest among the countries of Central Asia, with the world's 15th largest proven natural gas and hydrocarbon reserves, and the 9th largest proven oil reserves. These resources account for approx. 60% of export and 18% of the gross domestic product (GDP) (2015) [1]. Kazakhstan is a large country (9th in the world in terms of area) with a significantly diversified climate, infrastructure, economic structure, and regional differences in terms of the possession of resources. The energy intensity of Kazakhstan's economy is very high, more than twice the global average. Among the Organization for Economic Cooperation and Development differ in their views on the reasons behind these discrepancies, depending on their research method and the impacting factors. For example, previous studies suggest different findings, with significant regional differences in energy efficiency [17,18]. Some authors have tried to measure energy saving opportunities, taking into account regional differences in electric power consumption [19], but their analysis lacks an in-depth consideration of the mechanisms for defining differences in energy efficiency. What is more, they were unable to identify the reasons for the mechanism's impact on energy efficiency [20]. Literature on integrating and mapping distributed generation in the renewable power grid provides similar proof with regard to countries that could achieve higher energy efficiency [21]. Previous studies have demonstrated a complex approach in measuring the energy and economic efficiency in residential buildings [22]. We propose an analytical scheme of regional energy efficiency discrepancies based on stochastic boundary production functions and measuring the role of the total factor productivity in regional energy efficiency discrepancies, assuming that the difference in total productivity is the main reason for regional discrepancies. This article is intended to complement the above studies and examine the impact of an administrative pricing monopoly on regional energy efficiency discrepancies.
The paper aims to determine and explain the main factors for power losses in Kazakhstan and the reasons for inefficient energy distribution within the country. First, the impact of an administrative pricing monopoly on regional energy efficiency is investigated. Secondly, the data used in the work to conduct an empirical study are described. Thirdly, the obtained results are discussed, followed by conclusions.

Materials and Methods
The paper attempts to demonstrate that the magnitude of administrative barriers directly affects the efficiency and competitiveness of business, as well as the final prices of goods and services for the end consumer. Identification of the presence and size of such administrative barriers, and consequently their impact on the sustainability of enterprise development was the purpose of a national study of production and transaction costs which was conducted in 2017 in Kazakhstan, in which the authors participated personally [23]. The research methodology based on the standard cost model (SCM) [24] using desktop and expert evaluation, secondary grouping, and factor analysis allowed for the analysis of data on the dynamics of costs of enterprises in Kazakhstan.
The research included a sample of 2781 enterprises out of the total number of 1,185,163 operating in Kazakhstan, representing different industries, with different shares in the GDP of Kazakhstan.
The division by size was carried out in accordance with the total share of economic entities in the country. Sectoral quotas considered the sector's share in the country's GDP since costs are part of the final value of the product. Industrial enterprises accounted for 13% of the sample, 24% agriculture, forestry, and fisheries, 12% construction, 26% wholesale and retail, 23% services, and 2% other. By regions, the sample was double quoted. The share of surveyed enterprises in the region corresponds to the region's share in the total GDP of the country. The distribution of respondents in the region by sectors is made in accordance with the sectoral structure of the economy established in each region. Thus, the sample fully reflected the sectoral and regional structure of the economy of Kazakhstan, which allowed to draw reliable conclusions. Table 1 shows the structure of the surveyed enterprises divided by size. Most of the surveyed enterprises were small businesses.
Taking into account the harsh continental climate, which is typical for all regions of Kazakhstan, both the use of technologically outdated electric power production methods of resources and the underdevelopment of energy-saving technologies, cost optimization of electric power, and heating supply are relevant to the country's business. Figure 1 shows the share of heating and electric power costs in the total costs of various industries. Table 1. Sampling structure of a study to estimate production and transaction costs.

Taking into account the harsh continental climate, which is typical for all regions of Kazakhstan, both the use of technologically outdated electric power production methods of resources and the underdevelopment of energy-saving technologies, cost optimization of electric power, and heating supply are relevant to the country's business. Figure 1 shows the share of heating and electric power costs in the total costs of various industries. The highest energy losses have been identified in the trade and metallurgy sectors, i.e., 10% of the total amount of losses. The paper investigates the energy losses patterns in these two business sectors (Table 2.) Table 2. Share of electric power and heating costs in the total cost structure, depending on the size of the business. As a result, the impact of electric power and heating cost affects business development. When power costs increase, every third enterprise observes a decrease in sustainability, and the critical impact leads to changes in performance indicators. The growth of power costs is particularly critical for small businesses. This study analyzed the data on the cost of growth for enterprises of various sizes, with the prevailing percentage of small businesses (Table 2, Figure 2  The highest energy losses have been identified in the trade and metallurgy sectors, i.e., 10% of the total amount of losses.

The growth of power costs is particularly critical for small businesses. This study analyzed the data on the cost of growth for enterprises of various sizes, with the prevailing percentage of small businesses (Table 2, Figure 2).  Energy costs have a direct linear dependence on the size of the enterprise as follows:

Share of Item in Total Costs
The energy costs are calculated by using the method of least squares as follows: a·n + b·∑x = ∑y a·∑x + b·∑x2 = ∑y·x (2) In this case, the equation of the linear dependence of electricity costs (trend) are shown in Figure  2 as follows: y = −1.9393x + 11.638, where the coefficient of determination is R² = 0.9225 and indicates presence of a strong relationship. The equation of linear dependence of energy heating (trend) is the following: y = −2.7781x + 13.28, where the coefficient of determination is R² = 0.9768 and shows presence of a strong relationship.

Common National Trends in Business Cost Analysis
The most significant expenses of the enterprise are incurred by the power and heating supply and transaction services of monopolists [23]. The smaller the enterprise, the greater the share of power cost, and the stronger the impact is on business sustainability. In a large enterprise, it is five times lower than in a micro-enterprise. Therefore, for small enterprises, power cost constitutes a survival threshold.
Small forms of business shape out the basis of the entrepreneurial ecosystem of the economy. Thus, it sets the foundation for the growth of new forms of business and it provides an environment for the formation and implementation of entrepreneurial initiative. The more favorable the conditions for the manifestation of the first forms of entrepreneurship, the greater the chances to develop businesses in the regions, creating new forms of products and services [25]. Small forms of business need state support not so much in the form of direct investment, but in the creation of conditions that do not hinder the manifestation of private initiative [26]. In the conditions of high energy Energy costs have a direct linear dependence on the size of the enterprise as follows: The energy costs are calculated by using the method of least squares as follows: a·n + b· x = y a· x + b· x2 = y·x (2) In this case, the equation of the linear dependence of electricity costs (trend) are shown in Figure 2 as follows: y = −1.9393x + 11.638, where the coefficient of determination is R 2 = 0.9225 and indicates presence of a strong relationship.

Small forms of business need state support not so much in the form of direct investment, but in the creation of conditions that do not hinder the manifestation of private initiative [26]. In the conditions of high energy consumption in Kazakhstan, the environment for the development of risky private entrepreneurship is impoverished, especially in industries that need stable conditions in the first years of existence.
The total cost of heating and electric power in the micro-enterprise (sole proprietorship) constitutes up to 20% of production costs, and in small enterprises, 16%. The GoK declares a policy of active support for small businesses, trying not only to increase GDP growth in non-resource-based industries, but also to create a middle class based on small business, as a democratic and financially sustainable fundament of society. However, having decided to create a small business to implement the innovative idea, the Kazakhstani entrepreneur will have to give a fifth of the expenses to pay for heating and electric power generated and supplied by the state and quasi-state monopolists. It is clear, therefore, that the energy policy of the state determines the real conditions for development of private entrepreneurial initiatives.
At the same time, power costs include not only direct costs for the consumed energy, but also from additional transaction fees, to be paid services to quasi-governmental monopoly organizations. These costs include not only services related to direct connection or disconnection of power and heating network to the main lines, but also agency services for obtaining permits and information on the free capacity of power and heating transmission (Table 3). Please note that tariffs for these services differ not only by region in Kazakhstan, but also depending on whether the power transmission and heat conducting organization are natural monopoly holders (NMH). Table 3. The distribution of the cost of services for the connection to energy infrastructure elements (electric power, heating) (% of the number of answers). Cluster 4 is characterized by a low specific energy consumption, but a high energy intensity (nearly maximum) and an average indicator of power costs. The cluster is represented by four regions: Aktobe, Kyzylorda, Mangistau, and West Kazakhstan.
Thus, almost half of the regions of Kazakhstan (Cluster 2) are represented by energy-efficient enterprises, which are characterized by a minimal share of power costs in their total costs, which confirms the presented hypothesis.
The energy efficiency policy of Cluster 3, represented by Pavlodar region, needs to be reviewed in terms of all aspects that comprise the process of rational use of electric power.
In addition, the regions that comprise Cluster 4 need to consider ways to reduce their energy intensity, which brings this cluster closer to the level of inefficiency.

The Price of Energy Barrier for Business
As mentioned above, apart from direct costs for electric power and heating, business also bears the related transaction costs. Table 7 demonstrates that a quarter of the surveyed entrepreneurs face transaction costs for obtaining permits (including those from the NMH subsidiaries) and practically every tenth of them bears the costs of bribes for the representative of the NMH subsidiary. These high transaction costs of business indicate that the GoK lacks a consistent support policy for the energy sector and small business. Table 7. Transaction costs of enterprises in the service sector.

The above structure of business and industry costs allow for the determination of the amount of financial resources that can be released into the economy by reducing the non-productive administrative barriers (Table 8). If direct production costs for electric power and heat are in a determined dependence on the volume of output, the associated transaction costs have no economic justification. The presented tables show that the formation of costs for energy infrastructure services has a major impact on the amount of fees, which cannot be justified by objective reasons.
Energy costs thus constitute a bottleneck that generates associated costs, exceeding the direct costs and triggering the total cost increase elsewhere in the value chain.

Regional Patterns of Costs for Electric Power and Heat Supply
Territorial analysis by region shows that there is no direct correlation between the climatic conditions and the duration of the heating season. Also, the analysis demonstrates that there is no direct correlation between the tariff level and the total fee. The transaction costs of energy services differ by region by a factor of six or more (Table 4). Source: own elaboration.
The Pearson correlation coefficient was used to determine the relationship between the two rows of variables. The correlation coefficient is calculated with the formula: ( where x, yare sample averages, defined as follows: The coefficient of correlation of average temperature of the winter period in regions with indicators of expenses is −0.11 for heat supply. The correlation of average annual temperature in regions is −0.15 for electric power supply, and −0.18 for heat supply, which is not statistically significant, but indicates a feedback: the higher the average annual temperature in the region, the lower the share of energy in the structure of company expenses. Figure 3 shows that the lower the average annual temperature and winter temperature, the higher the share of electric power and heat costs in almost all regions across Kazakhstan is. Figure 3 presents exceptions, e.g., Kyzylorda, Mangistau, and South Kazakhstan regions where, at rather high annual average temperatures, the share of costs for electric power and heat supply is quite large. This fact can be explained by two reasons: 1.
The desert climate in summer requires intensive air conditioning and cooling in offices and in public facilities.

2.
These regions have the highest administrative barriers, with widespread bribery on the part of NMHs.
Thus, if the cost of energy consumption is independent of climatic conditions, then it is dependent on other, less obvious and biased factors.
One of the hypotheses in the paper is that there is a correlation between the number of natural monopolies, the number of services they provide (Table 5), and the share of power costs of enterprises.   The calculated correlation coefficient between the number of NMH subsidiaries and the share of costs for electric power supply is 0.5, which points to a stable relationship. The more subsidiaries there are in a region, the greater the share of costs spent on the services of these monopolies. This situation leads to the conclusion that free-market business contains the natural monopoly. This conclusion is also confirmed by the survey of entrepreneurs, which shows that there is a significant corruption component in power costs [23].
Improving energy efficiency is directly related to reducing energy consumption. But in the case of a cold climate and a large territory, it is not possible to reduce the energy consumption of heating. At the same time, finding a balance between the optimal proportions of energy consumption and the development of the region's economy is recommended. Basic social standards are met, first of all, by introducing low-energy production facilities, mastering new energy-efficient equipment, reducing Energies 2020, 13, 2947 9 of 19 losses and unproductive expenses of fuel and energy resources. At the same time, it is necessary to set goals for reducing the costs of enterprises for heating and electric power in the overall cost structure of the enterprise.
The authors examined the following comparisons to search for these optimal values regarding the energy intensity of the regions with these specific electric power consumption levels and the share of electric power costs in the total costs of enterprises (Figures 4 and 5) Energies 2020, 13, x FOR PEER REVIEW 10 of 21 At the same time, finding a balance between the optimal proportions of energy consumption and the development of the region's economy is recommended.

The horizontal axis of Figure 4 shows the regions of Kazakhstan in the order previously shown in Table 5. The vertical axis shows the value of electric power consumption, attributed to an average of 1 enterprise in the region (specific energy consumption). As observed in Figure 3, the largest specific energy consumption in region 12, i.e., Pavlodar, is 2.65 million kWh for one enterprise and significantly differs from other regions. The average value of specific energy consumption for Kazakhstan is equal to 0.42 million kWh. Also, Pavlodar has the highest energy intensity (as observed by the size of the sphere corresponding to this region). In addition to the Pavlodar region, no. 6 (West Kazakhstan region), no. 9 (Kyzylorda region), and no. 10 (Mangistau region) are characterized by high energy intensity, the value of which is 2-3 times higher than the average value in Kazakhstan.
The high energy consumption and energy intensity of the Pavlodar region can be explained by both climate (the temperature in winter can drop to −40 • C) and industrialization of the region (it is a location for a number of energy-intensive non-ferrous metal works).
As regions with low energy consumption, West Kazakhstan, Kyzylorda, and Mangistau are highly energy intensive. Considering that the main industrial profile of these regions is oil production (without oil refining), a high energy intensity indicator may indicate insufficient energy efficiency of the technology and equipment used, including losses due to the inefficient operation of electric power suppliers.
The upper third quarter (horizontal) of Figure 4 presents regions with high energy intensity: West Kazakhstan, Kyzylorda, Mangystau and Pavlodar. As observed in Figure 5, the size of the sphere corresponding to the Pavlodar region, which presents the share of electric power costs in the total costs of the region's enterprises, is the largest among all of the regions and 2.2 times higher than the average value in Kazakhstan. These areas represent the group of the least energy efficient regions of Kazakhstan.
The central part (horizontal) of Figure 5 presents regions with an average energy intensity, namely Aktobe and Karaganda. The share of electric power costs in Aktyubinsk is equal to the average value, and in the Karaganda region, it is 1.5 times higher than the average value in Kazakhstan. Both areas are industrialized.
The lower third (horizontal) of Figure 5 presents the most efficient regions, in terms of both energy intensity and power costs.
Based on the diagrams considered, the authors propose that the low electric power efficiency of the regions is not so much due to energy-intensive products manufactured in the region, but by inefficient (outdated) technologies and equipment located in such regions.
To test this hypothesis, this analysis applies a mathematical clustering of regions according to three previously applied variables: electric power consumption, energy intensity, and the share of electric power cost in the total costs of enterprises.
Using the Ward method and the principle of Euclidean distances, the authors developed a dendrogram of the distribution of regions ( Figure 6).
In Table 6, at a confidence level of 10, four clusters of regions can be visually identified. Furthermore, the authors used the k-means method for clustering 16 regions of Kazakhstan, and developed a graph of the distribution of average values shown in Figure 7.   Table 6, at a confidence level of 10, four clusters of regions can be visually identified. Furthermore, the authors used the k-means method for clustering 16 Table 6, at a confidence level of 10, four clusters of regions can be visually identified. Furthermore, the authors used the k-means method for clustering 16 Table 6 presents details of the values of indicators per cluster. Cluster 1 includes Atyrau, Karaganda, Kostanai, and South Kazakhstan regions and it is characterized by small values of specific electric power consumption and energy intensity. Its average power cost index is also slightly higher. Cluster 2 is characterized by maximum energy efficiency. This is the biggest cluster in Kazakhstan, and it includes Aktobe, Almaty, Zhambyl, North Kazakhstan, and East Kazakhstan regions, as well as the cities of Astana and Almaty.
Cluster 3 represents the Pavlodar region and is characterized by minimal energy efficiency. The indicators under consideration are the highest, as observed above in Figures 4 and 5. Cluster 4 is characterized by a low specific energy consumption, but a high energy intensity (nearly maximum) and an average indicator of power costs. The cluster is represented by four regions: Aktobe, Kyzylorda, Mangistau, and West Kazakhstan.
Thus, almost half of the regions of Kazakhstan (Cluster 2) are represented by energy-efficient enterprises, which are characterized by a minimal share of power costs in their total costs, which confirms the presented hypothesis.
The energy efficiency policy of Cluster 3, represented by Pavlodar region, needs to be reviewed in terms of all aspects that comprise the process of rational use of electric power.

Such proposals were made by the working group based on the results of the analysis of frontal costs in 201. It was assumed that, by 2020, the level of total costs hampering business development will gradually decrease. The total amount of potential cost savings for the business could be KZT 254,973.9 million or USD 814.6 million at the current exchange rate during the study period. These funds could be used both to support business operations and to invest in the development of new production facilities. Back in 2017, the GoK was concerned about the high level of business costs incurred by the domestic enterprises and the proposed changes could make Kazakh business more resistant to adverse external influences. However, by 2020, the proposed measures have not been implemented as planned.
Previous studies have shown that a significant cost share of accounts for energy use costs regulated by quasi-state structures [24]. At that time, reducing even some of the administrative barriers could save business considerable funds and lead the country's energy policy into a new model of efficient consumption.
The impact of increasing power costs and the associated service and trade costs is particularly critical. With the first deterioration of external conditions, the services sector in general and trade in particular are unable to cross the critical threshold of costs of rent, utilities, and contributions to monopolists for the use of resources.
In the structure of expenses of trading enterprises, total expenses for heating and the electric energy constitute 10.5% and is the largest cluster of operational costs related to location (see Figure 8). Trading in Kazakhstan has industry-specific and region-specific patterns that affect the cost structure the enterprise. In trade, typical factors depend on the size of the rented space and a high share of overhead costs, the country's characteristics, i.e., large open areas, low population density, and the total small market capacity, as well as significantly varying climatic conditions. Those factors (rent, waybills), which are part of the overall management process, became a prerequisite for business survival in Kazakhstan. The increase of rent and overhead costs in global trade is usually regulated by changes in the pricing policy and the optimization of the entire production process, but in Kazakhstan, low market capacity does not allow for enough turnover and the compensation of costs. In addition, indirect fees for monopolists for services related to energy transmission, as well as bribes, account for a significant share of trade business costs. Practice shows that, as the economic situation deteriorates, the size of these costs doesn't decrease and their share in total costs is even higher. According to the survey results, 40% of entrepreneurs in the trade sector had faced this problem.
Thus, the associated costs are clustered around the increasing electric power and heating consumption in trade, resulting in up to one-third of total costs and exceeding other cost groups. These costs can be called "knots" not only because they combine 6-10 types of costs related to their Trading in Kazakhstan has industry-specific and region-specific patterns that affect the cost structure the enterprise.

It is the increase in rent and utility charges that is a critical threshold, which trade enterprises cannot overcome in the case of unfavorable conditions, even in a short period of time.
By early 2020, the share of small and medium-sized enterprises (SMEs) in Kazakhstan's GDP increased to 29.5% and the number of its employees reached 3.3 million. The structure of SMEs in Kazakhstan is still dominated by service companies, especially traders. The growth in the number of trading companies over the last seven years has had almost no impact on the stability of business, and the service sector remains volatile. Given the favorable market conditions in the past years, the number of new arrivals and shutdowns in trade has almost equaled.
Trade is attractive for SMEs, and is the leading sector in terms of new enterprises, with approx. 16,000 enterprises registered annually. However, trade enterprises are fragile, as they can go bankrupt just as quickly (see Figure 9). Over 60% of small enterprises in liquidation are wholesalers and retailers (2700) [23]. The largest number of SMEs that have suspended their activities is also in the trade sector, i.e., 29,800.    Figure 10 shows the factors that have put additional strain on the business and created bankruptcy risk. The inability to pay for rent and utilities is the main threat for half of the SMEs and almost all forms of off-line trade.
Based on the observation of the market situation in Kazakhstan, it can be concluded that service companies (see Figure 11), especially in the trade sector, incur huge losses and may go into bankruptcy soon. Entrepreneurship in Kazakhstan has not yet become a stable part of the economy, and with the loss of income from domestic businesses, small entrepreneurs will join the ranks of the unemployed if the income from their businesses is lost.
Research shows that the enterprises of the service sphere, especially trade, bear huge losses and will go bankrupt in the near future.

Discussion
In recent years, interest in regional energy efficiency research has been observed in a number of countries. For example, in China, a spatial analysis of factors affecting regional energy efficiency allowed the authors to draw conclusions about the need to [25]:  Improve the quality of electric power and optimize the structure of the regional economy.  Promote energy saving and enhance the technical level of local enterprises.  Promote the general development and strengthening regional coordination.
Based on a regional approach to improving energy efficiency in Finland [26], it has been argued that "increasing the energy efficiency is one of the key elements when transferring energy systems towards sustainability, and procedures and solutions towards lower emissions, and also increased energy security and improved competitiveness, are often executed at the regional level".
Modelling the methodology for regional energy efficiency assessment and forecasting [27] allows the Chinese authorities to recommend different energy policies for different regions. For regions with low energy efficiency, it is crucial to control the distribution of energy resources. A more production, 13% trade 18% services; 69% Figure 11.

Based on a regional approach to improving energy efficiency in Finland [26], it has been argued that "increasing the energy efficiency is one of the key elements when transferring energy systems towards sustainability, and procedures and solutions towards lower emissions, and also increased energy security and improved competitiveness, are often executed at the regional level".
Modelling the methodology for regional energy efficiency assessment and forecasting [27] allows the Chinese authorities to recommend different energy policies for different regions. For regions with low energy efficiency, it is crucial to control the distribution of energy resources. A more extensive use of resources should no longer be allowed. In addition, the local government should create an incentive to improve "clean" energy technologies and reduce energy losses. In regions with moderate energy efficiency, it is important to focus on the technological improvement of the production process. The use of energy-saving, pro-environmental technologies should be encouraged and supported financially. For regions with high energy efficiency, it is necessary to focus on controlling the scale of energy supply from other regions.
Kazakhstan's energy sector faces a number of systemic problems, which have been exacerbated by the decrease in global energy prices, a reduction in industrial production in the context of the pandemic and a drop in demand for electric power. The World Bank's report "Stuck in transition: reform experiences and challenges ahead in the Kazakhstan power sector" [28] focuses on the risk of security of supply, significant investment needs, and the need for effective regulation and continuous reforms.
Based on the results of the study of frontal costs [29], the GoK proposed and discussed measures to reduce administrative barriers, providing business with a total cost reduction of KZT 580.6 billion, which as of 2017 is equal to USD 1.85 billion. Only a partial reduction of regulations on fees for energy infrastructure monopolists could provide savings of as much as KZT 255 billion.
In addition, the GoK plans to spend KZT 300 billion on the "Employment Roadmap". This will allow creating 250,000 jobs and implementing not only local, but also several national facilities, including construction of water reservoirs or dams. However, it has already been predicted in the worst-case scenario that the crisis will affect at least 2,000,000 workers in the SME sector and potentially up to 500,000 could be unemployed ( Figure 12). including construction of water reservoirs or dams. However, it has already been predicted in the worst-case scenario that the crisis will affect at least 2,000,000 workers in the SME sector and potentially up to 500,000 could be unemployed ( Figure 12). Small businesses can't use tax holidays and direct incentives they have been granted by the GoK, since the savings are spent on power fees and related costs. Enterprises are unable to change their energy consumption regime and thus reduce costs, and government assistance is ineffective. As a result, SMEs go bankrupt and become a social burden for the state. Thus, a country with rich natural resources may find itself in a catastrophic economic and social situation amidst dropping oil prices and a forced stagnation due to a global pandemic.
It was decided to provide another KZT 600 billion for crediting the operational capital of SMEs at 8% per annum. The income tax exemption should allow businesses to save more than KZT 380 billion in three years, and to allocate the released funds for development. The campaign will cover 1.2 million SMEs [30].
Attracting foreign investors to Kazakhstan is hindered by significant state interference in key markets, including the energy market. To increase global competitiveness, the country's free-market institutions should work transparently, fairly, and efficiently [31].

In Kazakhstan, there is no competition in power supply to retail customers and no freedom of choice with respect to electric power suppliers [28]. This is exemplified by the lack of information about the free capacities of electric power suppliers. Subsidiaries of NMHs do not provide reliable information on the free capacities of nearby transmission substations, and entrepreneurs are told to connect to other substations, which in turn increases their cost of connecting to the power grid.
Significant fragmentation, a non-transparent ownership structure, the strong influence of politics on tariff pricing, a lack of funds for the modernization of power production infrastructure, and inefficient operation make energy distribution the weakest link in Kazakhstan's energy sector [32].
Another disadvantage of the retail market is that several suppliers are closely linked to energy producers as subsidiaries, and therefore are not interested in finding the cheapest power supplier in the national market, which hinders competition [33].
The tariff system is based on the traditional "cost-plus" principle, which reduces incentives for regulated companies to minimize costs and improve service quality. This disadvantage is observed in Kazakhstan along the entire value-added chain of electric power supply. The greatest potential for operational cost reduction is in the supply chain, which accounts for about 50% of the total energy saving potential [34].
Decreasing state interference in the economy and developing competitive, private sector-friendly markets is obligatory. The country recognizes the need to develop national business and runs a number of support programs in this respect. However, these efforts are actually undermined by the macroeconomic environment that does not support the private sector. The financial sector does not provide businesses with accessible resources, local governments create unequal conditions and administrative barriers, and the quasi-state sector crowds out innovative entrepreneurship, including in the energy sector [35].
In the modern economy, electric power turns out to be not only an economic factor, but also a political one. Energy policy forms the model of economic and business development as in the other countries across the globe [36]. In the value chain, power consumption triggers business costs, and as a result, the final cost of a product. Only with a transition to new energy models can the traps of a raw material economy be avoided.
