Energy Sector Enterprises in Digitalization Program: Its Implication for Open Innovation

The digital economy implies structural transformation in many industries, including the energy sector, without considering the state specifics of the industry, for which full-fledged digitalization can be harmful. The aim of the study is to develop a methodology and to determine the level of digitalization in the energy sector in an intercountry context. Based on the methods of comparison and analysis, the work analyses the concept of “digitalization” and defines the indicators applied to the assessment of digitalization. The developed methodology is based on the index method, which makes it possible to assess the rating of countries by the level of digitalization in the energy sector. The article discusses modern technological development and socio-economic aspects that determine theoretical research and the development of digitalization in the energy sector. The reasons and stages of digitalization in the energy sector are highlighted. Using the comparison method, the analysis of existing approaches to assessing the digital energy of enterprises is carried out. End-to-end technologies are highlighted, as well as their practical application at the enterprises of the energy sector. An analysis of the key areas for the development of digital energy is presented. Conclusions are made about the feasibility of developing microprograms and the main directions of digitalization are highlighted.


Introduction
The transformation of the energy sector is currently affecting all energy systems of the countries of the world. Such a transformation is due to the implementation of the principles of sustainable economic development, since energy policy is associated with measures to ensure climate and energy sustainability, as well as socio-economic characteristics of a particular territory [1]. Accordingly, the main tasks of the energy sector are to ensure not only reliability, but also the economic, technological, social efficiency of the entire heat and energy saving of the country, and also to act as the key driver of the economic development of the territory. The main instrument of the tasks set is the innovativeness of the energy system, digitalization and integration of territorial production complexes, the involvement of consumers in a single energy system [2]. In conditions of the transition to the development of new sources of renewable energy, the issues of digitalization are becoming more relevant. According to the Global Wind Energy Council [3] in the world Energy, as of 2020, wind turbines with a capacity of more than 600,000 MB are installed; the main wind energy producers are China over 220,000 GB, the USA over 98,000 MB, and Germany over 60,000 kg. International Solar Energy Association Wood Mackenzie Power and Renewables notes that more than 2.2 million solar power plants have been installed by 2020. At the same time, in the United States, it is planned that by 2023 this figure amounted to 4 million solar power plants. China is the world leader in the production of electricity from renewable energy sources: at the beginning of 2020 generation was about 800 GW-twice as much as in the United States, which ranks second in the world [4]. Therefore, the management of consumption over time is an important tool for the mobility of the energy sector in the framework of the implementation of programs that are renewable from electricity. Taking into account that the vector of many countries, especially European ones, is aimed at the development of renewable energy sources (RES), the ongoing studies made it possible to determine and evaluate the possibilities of combined or sequential use of solar and wind energy, depending on the characteristics of the territory with high spatial and temporal resolution, and the daily progress of the use of energy sources, depending on the month and on the time scale. The results obtained allow for optimizing the production of electricity and heat [5]. Research on the imitation of natural ways of converting wastewater into drinking water in the form of steam as an unconventional energy resource is becoming promising. In addition, the use of solar energy using advanced materials for the production of filters allows us to create new designs with photocatalytic filters for water purification [6].
Another important direction in the transformation of the energy sector is the expansion of the range of applications of solar energy in the food industry and other industries [7].
Countries with a high level of wind potential with state support allow the development of new innovative RES projects [8]. In the development of the energy sector, a large role is played by small companies that produce RES in areas with large wind potential. At the same time, when developing a strategy for transforming the energy sector, it is important to take into account internal and external factors and the problems of operating large and small energy enterprises [9]. The digitalization of production processes and the use of end-to-end technologies in the implementation of the above innovations will make it possible to minimize the costs of the energy sector and provide competitive services to end consumers.
For example, in [10], findings show that the global experience of digitalization is quite positive, including the creation of various information systems, but this does not cover the fuel and energy balance as a whole.
At the same time, it is important to keep in mind that digital development is associated with national culture, as well as the mentality of the population of a particular territory [11].
It is also worth noting that the energy sector requires new approaches to its arrangement due to increased requirements for environmental protection [12].
There are a number of works devoted to renewable energy sources [13][14][15], but they are also more informative and general.
Thus, the issues of the practical application of digitalization tools in the activities of enterprises in the energy sector, studies of transformation assessment are not enough disclosed in modern literature, which predetermines the relevance of this study.
The main purpose of the presented article is a comprehensive disclosure of the features of digitalization in relation to the energy industry, an assessment of the digitalization of the energy sector in the context of countries based on the developed methodology, and the identification of contributing and negative factors of digitalization.
The object of the research is the energy sector in a country context, and the subject of the research is the process of digital transformation.
The scientific significance of the presented study lies in the following provisions. The main stages and prerequisites for the digitalization of the energy industry are determined, its content and the resulting effects are indicated. Digitalization affects all areas of activity and involves the integration and transformation of the energy system, and allows an understanding of socio-economic effects (the authors proposed specific indicators). The study of existing approaches to the content of digitalization made it possible to determine the main directions of digitalization and the introduction of end-to-end technologies.
To develop activities and further directions of digitalization, approaches to studying the readiness of countries in this transformation are summarized. This has allowed the authors to single out five groups of indicators that give an objective assessment of the digitalization index of the energy sector of a particular country. Approbation of the methodology and the results obtained formed the basis of factor analysis with the allocation of limiting and contributing factors. The scientific transformation of the proposed methodology is the compilation of existing approaches, considering important components of digitalization such as human capital and environmental sustainability in the country.
In the digital economy, information, and methods of managing and using it are determinants of the efficiency and development of the real sector of the economy. The activities of the energy sector are directly related to other industries; therefore, the digital divide in agribusiness and energy enterprises occurs in all countries and is a pressing issue [16]. Digital imbalance in industry affiliation negatively affects the socio-economic position of the territory or the region under study [17]. Digital imbalances have a positive or negative effect on information flows and the establishment of communications in society, providing socio-economic consequences for these processes.
The growth in the use of digital technologies in the workplace leads to a demand for new digital skills in three areas (General ICT Skills, Professional ICT Skills, Complementary Skills) [18][19][20][21].
The results of the main prerequisites for digitalization were: -Digitization of the current operating model. The most advanced companies are rethinking or building from scratch back-office processes to realize the potential of robotization: robotic automation of processes, digitalization of internal interfaces ("joints") and interaction with the consumer, increasing the availability of data and their use in decision-making, digitalization of personnel management tools, and updating IT infrastructure. In power distribution, the first candidates for digital transformation are processes that involve many repetitive actions: connecting new consumers, maintaining the network, managing investments, equipment data, and losses [22]. Using advanced analytics, a company must have a plan to "cleanse" and standardize data collected from multiple sources. Sources and data models must be interconnected with each other. -It is necessary to build up the competence of employees in the use of advanced analytics because the introduction of technologies, for example, "smart" counters [23], significantly increases the amount of data compared to manual collection, and indepth analysis of these data cannot be carried out using standard tools (for example, Excel tables). -Utilities should also partner with financial, e-commerce and telecommunications players in order to expand their portfolio of products and revenue streams. The diffusion and development of technologies depends on the specific region, on the availability of state support and the company's willingness to invest. -Important support for the existing system in order to add power generation capacity, continue the asset management strategy through big data analytics and centralize remote maintenance, ensure system stability in real time, automate, and digitize processes, implement customer interaction platforms, and use predictive analytics by customer, as well as offering smart home products and energy management services [24].
The article is divided into several parts as follows. In the first part, a literary review of the features of the energy sector transformation towards the development of RES, and an overview of digitalization tools, as well as the main prerequisites for the digitalization of the sector, are outlined. The second part presents the research methodology, data collection for the formation of a methodology for assessing the digital readiness of the energy sector of different countries. The results indicate the final values of testing the methodology. The discussion presents the achieved results differing from the existing studies. In the final part, the conclusions of the research are presented with further recommendations for promising areas for study.

Materials and Methods
This article uses general theoretical methods of scientific knowledge, such as synthesis, deduction, induction, and analysis, as well as a set of statistical and index methods. The comparison method made it possible to generalize the existing approaches to the essence of digitalization in the energy sector, the factors influencing its transformation and the system of indicators for its assessment.
Information base. Data from international energy and economic organizations (International Energy Agency, etc.); research by domestic and foreign scientists.
We will highlight the main stages of digitalization of energy sector enterprises and the resulting effects.
Having considered the prerequisites for the digitalization of an enterprise in the energy sector, we have identified 7 stages presented in Table 1, which indicates that digitalization is penetrating all the activities of enterprises. As part of the last 7 stage, a separate area that provides the initial basis for the digital transformation of the organization of production assets management is the implementation of production asset management (EAM) systems based on the creation of intelligent maintenance and repair (service) systems. Information subsystems for organizing product sales, organizing procurement activities, and document flow are also generally automated. At the same time, the main task of digitalization of an energy enterprise is the consolidation of information subsystems, avoiding disparate solutions, the creation of a unified system-platform for resource management, as well as logistic, contractual, planning and accounting analytics. The second task, no less important and allowing us to precisely declare the digital transformation of business, is the deep integration of systems. Taken together, these should not represent disparate platforms, but they should be very tightly integrated with the main core of resource management. The resulting synergistic effect of digitalization is global and is not limited to the considered narrow sphere of production, transport, distribution, sale, and consumption of energy resources. The goal of digital transformation is not in solving individual narrow-profile tasks, which were mentioned above, but in the onset of a new technological order that provides qualitatively new conditions for human life. Automation [26] Current trends in the development of software and hardware. Reducing the amount of work required to produce certain goods and provide services

2010-2019
Transformations-growing advances in the development of advanced technological areas, including AI, robotics, blockchain, virtual and augmented reality technologies, and several others Improvement of the technical base, the impact on the efficiency of the use of production assets and capacities, an increase in the share of materialized and a decrease in living labour per unit of output [27] 2019-present Transition to the online format of managers and employees of the energy sector Digitalization of business processes, which allows organizing the work of the energy grid's employees at a remote location [28] 3. Analysis The energy sector has its own internal focus, and it is important to set digitalization objectives within the sectorial aspects. Therefore, Austrian researchers presented studies of the digitalization of the energy sector былo [29] in relation to a hydroelectric power plant, highlighting digitalization in personnel management, big data for analysing the data of installed sensors using digital twins of stations, which allow prediction of the failure of important elements and components and for optimizing efficient operation. This makes it possible to increase labour productivity by 15% and reduce the number of employees by 3% (Table 2). Table 2. Economic effect of using big data in energy (developed by the authors).

Thus, several scientists believe that digitalization should be viewed through the prism of 3-4 levels of physical, infrastructural and business [35][36][37][38][39]. In some works [36], it is indicated that the digitalization of energy is developing in 14 directions.
Based on the analysis of the literature, we will consider the main components and content of digitalization in the energy sector. According to the report of the National Research University "Higher School of Economics", digital transformation implies the sectorial principle of supporting the introduction of new technologies on the principle of introducing any and through the forced introduction of a variety of technologically diverse solutions that are in demand in a given sector of the economy or social sphere [40].
We agree with the materials of the Ministry of Energy of the Russian Federation, which indicate that digitalization makes it possible to manage complex energy systems. It contributes to the development of a wide range of new technologies and opens up access to the markets of the future [41, 42]. Table 3 presents the main approaches to the content of digitalization in the energy sector. Table 3. The essence of digitalization in the energy sector according to the criteria identified by the authors of the article (developed by the authors).

The scope of digitalization is wide enough. Summarizing the main directions of digitalization development in Table 3, we will draw the main conclusions:

1.
Digitalization is an approach that aims to create a digital picture of the surrounding world, but in a format suitable for computer processing.

2.
Digital twins-a constantly updated digital model of an object, which receives data from special sensors, it becomes possible to simulate its behaviour in the real world to help save resources. This helps to improve the quality of the product, reduce costs, time costs, and promptly meet customer requirements. 3.
The factory of the future is based on the "communication" of smart equipment and all systems of the enterprise with each other: each object receives its own digital model and provides data transmission. This allows us to move to a completely new state of production-the Industrial Internet of Things (IIoT)-which is being actively developed all over the world.

4.
Technologies based on cyber-physical solutions and full automation of production are the basis of the next industrial revolution-Industry 4.0. The world of the Internet of Things (IoT) implies the ability to influence physical objects by changing their digital counterparts.

The main factor in the development of Industry 5.0 is the adaptation of existing digital technologies to the individual needs of consumers.

Results
Currently, quite a few models have been developed for assessing the digitalization of countries. To identify the most general and priority areas of assessment, we will summarize a number of approaches (Table 5). Table 5. Approaches to the study of the level of readiness of digitalization of objects [62].

MIT Digital Business Center
Based on the analysis of more than 400 large companies from various industries, three key areas of digital transformation were identified: customer experience (Transforming Customer Experience), operational processes (Transforming Operational Processes) and business models (Transforming Business Models) [21] Digital maturity model Deloitte [22] 27 assesses digital opportunities on 5 key dimensions: consumers, strategy, technology, production, structure, and culture of the organization (Customer, Strategy, Technology, Operations, Organization and Culture). The five main dimensions are subdivided into 28 sub-dimensions, which in turn are broken down into 179 metrics against which digital maturity is assessed. The emphasis is on the Business Strategy, which determines the focus of the transformation Digital Transformation Index Having considered in detail the above methods, we will define an algorithm for assessing the digitalization of countries' readiness using the index method. For a more complete assessment, it is proposed to divide the system into 5 groups of indicators. Table 6 shows the approaches to the study of the level. Group 1-"human capital", characterizes the level of professional industry training and the structure of labor force employment in the energy sector, the more people are employed in this industry, the higher the level of emergence of industry transformation initiatives; Group 2-"reliability and quality of power supply", the lower the reliability, the more difficult it is to make a decision on any reforms without solving the main problems of the industry; Group 3-"availability of electrical energy", the higher the prices for electrical energy, the lower the competitiveness of the economies, which means that it is easier to decide for transformation. For the population, the issue of access to energy efficiency is also important, and for business, the inertia of connecting new consumers is low; Group 4-"operational and investment efficiency", the development of MRE provides an incentive for the emergence of new players in the market of generating companies for which debt financing is important. In addition, it is difficult to develop the energy sector of the new paradigm without foreign investment; the country's openness in this matter is also assessed; Group 5-"environmental sustainability and political and infrastructural readiness of the country for digitalization", the environment today, first of all, forms the political image of the country, which is necessary. "Structure of the electric power system", it is easier to start digitizing the industry; on the other hand, in the absence of a sufficient volume of large-scale gas generation and hydro generation, problems may arise in balancing the electric power system. Without the desire to create a new regulatory framework, transformation will not happen, just as without equal conditions for the vision of business for all potential investors.
The main advantage of this technique is the selection of a set of indicators, the value of which is determined centrally, publicly presented on the websites of economic regulators and official statistical bodies. In addition, the human factor, and indicators of sustainable development of territories, are taken as important points. In determining a set of indicators, the approach was partially used [62].
To build an integral index of digitalization of countries, you first need to find the partial indices for each region in the five blocks indicated above.
For this, the indicators are normalized. Since they are all calculated as a percentage, rationing is made according to the formula UGTij = Xij/100 (1) where UGTij-private index of the i-th block for the j-th region; Xij-indicator of the i-th block for the j-th region.
Since the analysis uses data for 2016-2020 years, after standardization of indicators for all years, the average private index is calculated for each country in five years as an arithmetic mean. To obtain the integral index of digitalization of the country (IC), the average partial indices obtained for five blocks are summed up. Furthermore, countries are ranked based on the obtained value of the overall digitalization index. The larger it is, the higher the country is in the ranking. Evaluating the results of calculations of the integral index of digitalization by country, they can be ranked.
As part of the approbation of the proposed methodology, at the first stage, the calculations of indicators were made in the period from 2016 to 2020. This is based on the official data, presented on the websites of organizations and rating agencies. Then, at the second stage, the arithmetic means are calculated at a specific indicator, the results of which are presented in Table 7.
UHC is an integral indicator for assessing the readiness of countries for digitalization in the energy sector, obtained by the index method; Cheka is an indicator of human capital; NDE-indicators of reliability and quality of power supply; DEE-indicator of the presence of electrical energy; OIE-indicator of operational and investment efficiency; EH is an indicator of environmental sustainability and political and infrastructural readiness of the country for digitalization.  Table 8 shows the results of the group indicators, as well as the sum of these indicators, the integral indicator of the digitalization readiness of the energy sector in the countries that are in the first group was calculated. The energy industry as one of the components of the real sector of the Swiss economy is a highly digitized point. This is confirmed by the third position in the international ratings of the IMD World Digital Competitiveness Rating (2020).
Switzerland is a leader in the implementation of green energy in the provision of smart cities. This result allowed us to take a leading position.
In second place Sweden. Sweden is one of the leading countries in the field of digitalization, which has become the main driver of the country's economic development in recent years. The share of value added by the information and communication technology (ICT) sector in Sweden is one of the highest among the OECD countries; moreover, the country is one of the ten largest exporters of ICT services in the world.
Canada is in third place. Nuclear energy is an important part of Canada's energy sector. Few know that Canadian nuclear power accounted for about 4% of global nuclear energy production in 2018 (sixth largest in the world). This is in a country where about 0.5% of the world's population lives. Here are 10 interesting facts about nuclear power in Canada: 1. Canada has several nuclear reactors. Today, 19 of the 22 nuclear power reactors built in Canada are in operation and located at several stations, mainly in Ontario.
United Arab Emirates-fourth place. The UAE government has made digitalizing its economy a priority in order to improve government efficiency, industry creativity and in order to provide international leadership. The UAE ranks first among the Arab countries of the Middle East and North Africa in terms of digital adaptation. According to this indicator, the Emirates are approaching the advanced states of the world. In addition, the UAE has the highest level of digital identity, which is measured using various indicators, such as access to services, electronic signature, etc.
Singapore is in fifth place. Singapore is on the heels of the leaders of the Asian venture capital market. $324 million was the volume of venture capital investments in Singapore last year, which is almost 10 times more than in Hong Kong, at $37 million. According to the Asian Venture Capital Journal, $5.5 billion was invested by venture investors in China by the end of the first half of 2015. Singapore is still far behind both China and India with $3.3 billion in venture capital investments. If, for example, in Singapore, such a transition took place in the first half of the 1960s, then in Malaysia, Thailand, the Philippines and Indonesia-and in the 1980s in Vietnam and China-this took place in the 1990s and in Cambodia, Laos and Myanmar in the 2000s (Table 8).
France-sixth place. France is one of the leaders in digitalization. France already has a well-developed traditional infrastructure: roads, water lines, housing, and communal services and even parking spaces. However, the state is not going to stop there and is now engaged in the development of digital infrastructure, hoping to increase productivity, create new jobs and improve the quality of life of its citizens in general.
As part of the approbation of the methodology, at the first stage, the primary indices or indicators were calculated for each country for the period from 2016 to 2020. These analytics were carried out for 30 countries, and three groups of countries under study were identified.
The first group includes countries with an integral indicator from 3.8 to 5.2. These are countries with a high level of preparedness for digitalization, having the results of digital projects with a high level of economic efficiency in the field of energy.
The second group is from 3.65 to 3.8. This is a group with an average level of readiness for digitalization of enterprises in the energy sector of the countries. At the same time, they have positive results in the development of digitalization projects for enterprises in the energy sector.
The third group is less than 4.05. The third group includes countries with a low level of digitalization. There is great potential, but perhaps insufficient funding and support from the state in the implementation of digital projects in the energy sector.
Russia took 23rd position in terms of the level of digitalization in the Energy Sector. In Russia, as in leading countries, large companies are the leaders in digitalization.
In contrast, small-and medium-sized enterprises (SMEs) are lagging behind in adopting new digital solutions. In general, highly concentrated industries dominated by large businesses with access to significant investment resources are showing greater progress in digitalization. At the same time, in various industries, the introduction of digital technologies, and even more so digital transformation, require different investments, including in terms of volume and in the timing of implementation. Digitalization of energy is associated with the proliferation of distributed smart energy systems and corresponding resource consumption patterns. In the electric power industry, one of the features is the uneven consumption of electricity. New digital solutions for managing energy systems and distributed energy technologies help balance supply and demand more efficiently and quickly and distribution of energy AI is most widely used by organizations in the mining complex (66.7%), the financial sector (46.4%), and in the energy sector (40%). In the electric power industry, digital transformation is aimed at improving the reliability of power supply, limiting the rise in electricity prices, as well as developing new formats (services) of interaction with consumers. The focus in this segment is the phased formation of smart grids at the national and local levels. Energy generation, distribution, transmission, and consumption are monitored in real time thanks to smart devices, and energy suppliers and consumers are testing various 'demand management' schemes. Moreover, projects are being implemented in the field of management and monitoring of the reliability of power supply. Platforms are being created for the collection, processing and use of big data (for applied and research purposes); the tasks of predictive strategic and investment planning are being solved [64].
At the same time, it is possible to single out factors that contribute to and negatively affect digitalization in the energy sector (Table 9). Table 9. Factors contributing to, and negatively affecting, digitalization in the energy sector (developed by the authors).

Constraints Contributing Factors
Illiterate expenditure of working time [65] Improving the quality of life Enhanced control at various nodes of the enterprise The emergence of economic and social effects Job cuts The emergence of human substitutes control systems Redefining familiar business models [66] Emergence of new business models Not fully ready for digital solutions Ensuring accessibility in the promotion of goods and services Lack of qualified employees [67] Increasing the transparency of economic transactions and ensuring the possibility of their monitoring Within the framework of this study, an analysis of the economic effects was carried out that allows one to obtain digitalization in the energy sector. These results are presented in Table 10.

Direction Results
Intelligent consumption management [68] In 2014, the market was estimated at $5 billion, the prospects for an increase by 2020-5 times Integration of renewable energy sources [69] The increase in the share of renewable energy sources in the balance will require greater inter-system integration with the expansion of the use of digital technologies

Intelligent charging of electric vehicles
Smart charging is impossible without digital infrastructure. It will reduce the power required for EV by 2040 from 140 to 75 GW (assuming the number of EVs is 150 million) The emergence of low-power distributed power sources Digitalization will allow integrating sources using technologies such as: blockchain, microgrids and virtual power plants Virtual Power Plants RES, in combination with batteries, by using digital technologies, can ensure the reliability of power supply Intelligent grids [65] Reduce the need for the construction of standby power plants, expand the possibilities for the integration of renewable energy sources and reduce the need to turn them off during periods of excess generation

Blockchain
In the future, it seems possible to create a self-regulating, autonomous, and self-balancing power system with millions of producers and consumers and automation of payments through microtransactions Intelligent consumption management [66] Dynamic variable rates are better suited for load management than rigid variable rates In addition to the existing methods, this study made it possible to clarify and determine the level of readiness for digitalization in the energy sector in different countries. At the same time, it should be noted that it is scientifically significant in that this methodology allows one to assess not only the level of digitalization, but also the degree of readiness of the country. In the long term, the country can increase these indicators, because the rating data are a potential result in the further development of digitalization of the industry under study. The main object of the study was Russia, which takes a confident position on the degree of readiness point. It is important to note that the study of this aspect requires a further consideration of the comma, including in the context of specific regions of the studied countries, in order to develop appropriate management decisions and in order to conduct effective analytics.

Discussion, Open Innovation in Energy Sector with Digital Transformation
Connection of innovations and digital activity of enterprises in the energy sector. Considering the features of the innovation of energy companies, it should be noted that innovations can provide a certain breakthrough in the emergence of new areas of activity, expanding the accumulated positive experience, which allows for a high level of development of society, the basic values of an individual or employees of an organization, and an increase in the competitiveness of enterprises in the sector. Digitalization is one of the tools used for innovation. It is important to note that the analyzed countries are at different stages of the energy sector digital transformation. The results of a country's digital readiness assessment indicate that the first group of countries were leaders in introducing innovations into the activities of energy companies, including the digitization of production and management processes. Tutak, M. and Brodny, J. conducted an assessment of the digital maturity of countries on the implementation of industry 4.0 technology. The study was of a global nature and concerned the entire real sector of the economy. In the presented analytics of the article, the focus is on the indicators of the energy sector country's digital readiness [70].
However, it should be noted that the results of the evaluation of the first group of countries coincide. Sweden and Finland are leaders in the digital maturity of their economies, as indicated by our results in the energy sector. The leaders are Western European countries with extensive experience in implementing digital technologies, innovations, and in changing corporate culture. The most common implemented technologies of Industry 4.0 are the Internet of things, artificial intelligence. Germany (4.06) belongs to the first group and has a high level of digital readiness of the energy sector. This is due to such factors as the introduction of state support for digital transformation in the Digital Energy Program for 2008-2013. In 2016, the law "On Digitalization" was introduced. Since 2018, innovation days have been held, at which the best results of digitalization in the energy sector are presented. If we consider the results of digitalization in dynamics, then in 2009 the NEXT virtual power plant was introduced; in 2013-cloud technologies by the Senec power plant; in 2014-Freinhofer cybersecurity; in 2017-Leonism trading; in 2018-business process automation E.ON etc. [71].
We note the correlation of the digital readiness of the energy sector with the assessment of the efficiency of the energy infrastructure of countries presented in the study by M.Yu. Shabalov and co-authors. The level of infrastructure development was assessed through the degree of use and implementation of renewable energy, the level of use of information technologies, digital technologies, the quality of materials science and the modernity of energy equipment, the introduction of energy-saving technologies and the share of non-renewable energy.
The US and Canada are in the best positions, as there is a high level of investment in the energy sector, and a low depreciation of the energy infrastructure, respectively. The investment gap is much larger compared to Russian companies. The second position is occupied by Asian countries, which have a lower level of depreciation in their energy infrastructure than the United States, but at the same time they have high investment needs, so there is a large infectious gap in the energy sector [72]. This means that the level of digitalization correlates with the level of equipment cost and digitalization of the organizational processes in the energy sector.
The results of the China energy digital readiness assessment are supported by studies on the implementation of open innovation for the energy efficiency of the industrial sector. Foreign direct investment plays an important role in the implementation of these projects, which, in turn, has a positive effect on the sustainable development of the country [73].
The high level of digitalization of European countries in the context of the energy sector correlates with studies that the ongoing institutional policy of financing R&D and innovation plays an important role, which makes it possible to ensure the efficiency of innovative systems of enterprises [74], also in relation to solar and wind energy projects [75].
Eco-innovations, meanwhile, are a kind of springboard for the transition to renewable energy sources. A study of the countries of the Organization for Economic Cooperation and Development confirms that the economic growth of the country depends on the development of highly qualified human capital to ensure an increasing share of the consumption of renewable energy sources, the introduction of innovations and the digitalization of business processes [76]. Technological innovations as an exogenous element of energy demand ensures the energy efficiency of Malaysia and confirms the level of digitalization of the country's energy sector [77].
At the same time, it should be noted that the open innovation paradigm is confirmed by the need to involve all stakeholders engaged in the implementation of energy efficiency projects in the industrial sector of the economy. Studies show that those companies that use open innovation tools are more likely to use them effectively and get more economic opportunities for successful activities [78]. It is the cooperation of the energy sector that makes it possible to obtain the maximum effect in the implementation of four such components as open innovations, innovative business models, non-productive innovations and openness of achievements. Therefore, the joint design and creation of projects for the introduction of innovations in the energy sector predetermine the relevance of international partnership for the energy transition [79].
The concept of Chesbrough, presented in 2003, is universal and is applicable to various industries, but the practice of its implementation in the energy sector shows the importance of collaboration and innovation management. A good help is the introduction of digital end-to-end technologies [80].
At the same time, the facts show that the regional disproportion of resource intensity does not allow the effective attracttion of talent, the effective introduction of innovation or any guarantees concerning the the qualitative development of the Chinese energy sector [81]. Inconsistency is also observed in the implementation of innovations by large Danish energy companies through the prism of conflicts and competition between various stakeholders. Their policy is aimed at introducing environmentally friendly technologies with open innovation tools, involving the maximum number of participants, information exchange, as well as coordination and control [82]. Open innovation involves collaboration in international, regional, and local enterprise partnerships. The results of studies of partnerships in countries such as the Netherlands, Spain, Germany, and the United Kingdom have demonstrated the effectiveness of the implementation of joint projects to introduce renewable energy sources in the field of solar energy. Another good example of partnership is the energy sector enterprises of Japan, Italy, South Korea, France, USA, which are leading researchers of international cooperation in solar energy projects [83]. When developing their strategy, a significant number of external factors are taken into account, a large amount of information sources is studied. In addition, joint projects in the field of solar energy and wind energy are being implemented. This allows intensive use of a sufficient number of external sources [84][85][86].

Theoretical and Practical Implication
Within the framework of this study, the relevance and importance of studying the readiness of countries for the digitalization of the energy sector is highlighted. The conducted analytics made it possible to identify the main prerequisites for the digitalization of the energy sector. In addition, highlight 7 stages of digitalization of energy in Russia, indicating the resulting effects and the content component of digitalization. Big Data analytics is one of the digitalization tools. Therefore, the paper presents the possible economic effects from the use of this tool in the energy sector. For the development of the categorical apparatus of the problem under study, the main criteria and approaches to the content of digitalization in the Energy Sector are highlighted, considering Russian and foreign scientists. The work identifies five main areas of digitalization, including end-to-end technologies. In total, 18 tools are highlighted, and their practical application is indicated. At the second stage, in the development of methodological aspects of digitalization in the Energy Sector, several approaches to assessing digitalization are outlined. There were highlighted five groups of indicators, which, in our opinion, will be able to give a real assessment of the country's readiness for digitalization in the energy sector; the corresponding indicators are also highlighted, which are based on data from rating agencies and analytical centers in open information. Based on the comparison method, the article presents several approaches of various countries in order to implement digitalization in their energy administration. In addition, the factors contributing or negative to the development of digitalization in the Energy sector are highlighted.
Modern trends in the transformation of the economy real sector are subject to the principles of implementing Industry 4.0 technologies. The conditions of instability of pandemic processes, globalization processes, and high levels of digital activity predetermined the need to study the energy sector of countries' digital readiness, the results of which can form the basis of a digital development strategy for an enterprise in the sector.

Limits and Future Research Topics
The presented article outlines the analysis results of the countries' digital readinesss. A high level was noted in the energy sector of the EU countries, Canada and Scandinavian countries and a low level was noted in the countries in the post-Soviet space and in developing countries. The digital divide is associated, first of all, with a large gap in the levels of investment in modernization, innovation, and digitalization of the energy sector enterprise. The energy sector of the first group in terms of digital maturity levels received a lot of government support through the implementation of government programs. For example, in the UK, a digital strategy was introduced in 2017, in Germany in 2017 an initiatives to create smart grids, data storage systems, etc. have been supported.
Of great importance is the work of agencies and associations whose activities are aimed at the development of energy clusters and the introduction of digital communications. Project activities of research institutes allow the development and successful implementation of successful projects related to big-data, digital sensors, digital twins, digital surveys, implementation of smart city tools, etc. In addition, the largest corporate projects related to the introduction of digital platforms are being implemented, and master classes in the field of electric power industry, mobility of digital thinking are being implemented. Start-up incubators are being developed for the efficient operation of enterprises in the value chain of the energy sector.
The presented analytics also made it possible to determine possible results in the energy sector when introducing digitalization into the production processes of an energy company. Thus, further research will focus on detailed consideration and highlighting of internal and external factors that will ensure higher levels of preparedness of countries for digitalization. The study helped us to identify the leading countries in terms of the level of digitalization in the energy industry, which can positively influence countries with a low level of digitalization, as well as the development of mechanisms and tools for digitalization in the industry.
In conclusion, we express the hope that all the scientific approaches we have proposed and the methodological developments that have been made will find a practical application for the development of the energy industry. Prospects for further development of the topic consist of developing methodological tools for the digital development strategy of countries with a low level of digitalization in the energy sector, conducting factorial digital analytics of the contributing factors for the development of the industry and building a forecast for the future.
